PREFACE.

The sexual life of woman—the appearance of the first indications of sexual activity, the development of that activity and its culmination in sexual maturity, the decline of that activity and its ultimate extinction in sexual death—the entire process of the most perfect work of natural creation—has throughout all ages kindled the inspiration of poets, aroused the enthusiasm of artists, and supplied thinkers with inexhaustible material for reflection.

In the following pages, this sexual life of woman will be considered both in relation to the female genital organs, and in relation to the feminine organism as a whole; in relation both to the physical and to the mental development of the individual; and in relation alike to the state of health and to the processes of disease. Thus from the standpoint of clinical investigation and of practical experience, the book will be a contribution towards the solution of the sexual problem, nowadays recognized as one of supreme importance.

It is thirty years since I published a work on the histological changes that occur in the ovaries during the climacteric period (Archiv. für Gynecologie, Vol. xii, Section 3); and ever since that time, the influence exerted upon the general health of women by the physiological and pathological processes occurring in their reproductive organs, has been to me a favourite subject for observation and experiment. The result of these studies is incorporated in my monographs, “The Climacteric Period in Women” (Erlangen, 1874), “Sterility in Women” (2nd Ed., Vienna, 1895), “The Uterus and the Heart” (Leipzig, 1898), and in various contributions to medical periodicals. I now have a welcome opportunity of drawing a general picture of sexual activity in women, and of illuminating this picture both by the light of my own experience and by numerous references to the works of other authors. In passing, I have devoted considerable attention to questions of education and personal hygiene, both of which are greatly influenced by the processes of the sexual life. Thus, I hope, the work will be rendered more interesting to the physician, and the general picture it is intended to convey will be more fully characterized by contemporary actuality.

Natural divisions of the subject are, I consider, furnished by the three great landmarks of the sexual life of woman: the onset of menstruation—the menarche: the culmination of sexual activity—the menacme; and the cessation of menstruation—the menopause. These several sexual epochs are differentiated by characteristic anatomical states of the reproductive organs, by the external configuration of the feminine body, by functional effects throughout the entire organism, and, finally, by pathological disturbances of the normal vital processes.

Thus in separate chapters a description is given of sexual processes, a detailed exposition of which will be vainly sought in the textbooks of gynecology, yet which are none the less of far-reaching importance in relation to the physical, mental, and social well-being of women, and in relation also to the development of human society; such topics are, the sexual impulse, copulation, fertility, sterility, the employment of means for the prevention of conception, the determination of sex, sexual hygiene. To the topics of pregnancy, parturition, lying-in, and lactation, since these are adequately discussed in works on midwifery, but little space has here been allotted.

It is my earnest hope that physicians and biologists may derive benefit from the book equal in amount to the pleasure I have gained in the work of writing it.

THE SEXUAL LIFE OF WOMAN.

By the sexual life of woman we understand the reciprocal action between the physiological functions and pathological states of the female genital organs on the one hand and the entire female organism in its physical and mental relations on the other; and the object of this book is to give a complete account of the influence exercised by the reproductive organs, during the time of their development, their maturity, and their involution, on the life history of woman.

From the earliest days of the medical art this sexual life of woman has aroused in the leaders of medical thought the highest interest, and for this reason great attention has been directed, not only to the anatomy of the genital organs and to the diseases of the reproductive system, but also to the individual manifestations of sexual activity and to the influence exercised by these on the female organism as a whole.

Several works by Hippocrates are extant on this subject, among which may be mentioned: περι Γυναικειης Φυσεος,[^[1]] a treatise on the physiology and pathology of woman; περι Αφορων,[^[2]] which discusses sterility in women; περι παρθενιων,[^[3]] a treatise on the pathological states of virgins. These writings of Hippocrates contain some very remarkable observations on the influence exercised by disorders of the reproductive organs on the general health of women.

Aristotle wrote at some length on the functions of the female genital organs. In the writings of Aretæus and Galen on the diseases of women we find striking observations, as for instance, in Galen’s De Locis Affectis,[^[4]] which contains a “Statement of the Similarity and Dissimilarity of Man and Woman.” Another notable work is that of Albertus Magnus, entitled De Secretis Mulierum.[^[5]]

The numerous works on the diseases of women published in the sixteenth century consisted for the most part of a repetition of the observations of ancient writers. The gynecological treatises of the eighteenth century, however, bore witness to an increased knowledge of the anatomy of the female reproductive organs, and were illumined by Haller’s researches on the functions of these organs.

The subject with which we are especially concerned is discussed in a work by Boireau-Laffecteur, Essai sur les Maladies Physiques et Morales des femmes,[^[6]] Paris, 1793; and also in Marie-Clement’s Considerations Physiologiques sur les Diverses Epoques de la Vie des Femmes,[^[7]] Paris, 1803. the same connection we must mention von Humboldt’s treatise, Ueber den Geschlechtsunterschied und dessen Einfluss auf die organische Natur.[^[8]] The first comprehensive work in which an exhaustive inquiry was made into the functional disorders of the female genital organs and the relation of these disorders to the female organism as a whole and to the physical and mental peculiarities of woman was Busch’s: Das Geschlechtsleben des Weibes,[^[9]] Leipzig, 1839.

In the second half of the nineteenth century a very large number of monographs were published, investigating and describing the reflex disturbances produced alike in the individual organs and in the nervous system as a whole by changes in the uterus and its annexa. Many of these works will be mentioned more particularly in the course of this treatise.

The sexual life, based upon the purpose, so important to every creature, of the propagation of the species, possesses in the female sex a vital significance enormously greater than sexual activity possesses in the male. From the very beginning of sexuality, when the idea of a bisexual differentiation dawns for the first time in the brain of the little girl, down to the sexual death of the withered matron, who laments the loss of her sexual potency, physical and mental activity, work and thought, function and sensation, arise for the most part, wittingly or unwittingly, from that germinal energy which is the manifestation of the unalterable law that the existing organism endeavors to reproduce its kind.

Every phase of the sexual life of woman, from the threshold of puberty to the extinction of sexual activity, the first appearance of menstruation, the complete development of the sexual organs, the act of copulation, conception, pregnancy, parturition, and the puerperium, finally the involutionary process which accompanies the cessation of menstruation at the climacteric period—every one of these sexual phases entails consecutive physiological processes and pathological changes alike in the individual organs and in the nutritive condition of the entire organism, in the functions of the cardio-vascular apparatus, of the brain and the nerves, of the skin and the sense-organs, in the processes of digestion and general metabolism. Herein we see a striking illustration of the old saying of von Helmont, propter solum uterum mulier est quod est;[^[10]] also of the similar aphorism of Hippocrates, uterus omnium causa morborum qui mulieres infestant;[^[11]] a conception summed up by Goethe in the words of Mephistopheles:

“Es ist ihr ewig Weh und Ach

So tausendfach

Aus einem Punkte zu kurieren.”

Just as in a tree the process of growth is made manifest to the superficial observer by the pleasure he feels at the sight of the buds and blossoms, by the refreshment he obtains from the fruit, and by the sadness which the withering of the leaves causes him, so in the sexual life of woman there are landmarks which no one can possibly overlook, by means of which three great epochs are distinguished. These are: puberty (the menarche), recognized by the first appearance of menstruation and the awakening of the sexual impulse; sexual maturity (the menacme), in the fully developed woman, characterized by the functions of copulation and reproduction; and sexual involution (the menopause), in which we see the gradual decline and ultimate extinction of sexual power and all its manifestations. In all these three epochs the sexual life of woman not only affects the hidden domain of the genital organs, but controls also all the vegetative, physical, and mental processes of the body, and is clearly and incontestably apparent in all vital manifestations. What Madame de Staël said of love is indeed true of the entire sexual life of woman: l’amour n’est qu’unc épisode de la vie de l’homme; c’est l’histoire tout entière de la femme.[^[12]].

The sexual life of woman is coextensive with the peculiar vital activity of the female sex, for it endures from the moment when individuality first begins to develop out of the indifferent stage of childhood until the decline into the dead-level of senility.

To illustrate this fact, I have drawn up a curve of the sexual life of woman, making use of the statistical data available in central Europe regarding the age at which menstruation first appears, the age at which maidens marry, the age at which the largest number of women give birth to a child, and the age at which menstruation ceases; and reducing the figures to averages. * denotes the fifteenth year of life, as the average age at the menarche; ** denotes the twenty-second year of life as the average age at marriage; *** denotes the thirty-second year of life, in which woman exhibits her maximum fecundity; **** denotes the forty-sixth year of life as the average age at the menopause. (Fig. [1].)

Not in this respect alone, however, is the sexual life of woman of paramount importance; it is, in addition, the mainspring of the well-being and progress of the family, of the nation, of the entire human race. In the evolution of man from the primitive state in which he existed merely for the performance of vegetative functions up to the highest stage of contemporary culture, in the history of all races and of all times, the sexual life has been a most potent determining factor. With that life, religion, philosophy, ethics, natural science, and hygiene, have been most intimately related; for that life, they have furnished precepts and laws. The history of the sexual life is identical with the history of human culture.

In a primitive condition of society, among people living in a state of nature and among the lower races of mankind, the sexual life of woman possesses no great general interest, the female being merely a chattel; the ownership of this chattel, moreover, being often temporary and transient. The investigations of anthropologists have shown that among primitive people this form of property is neither highly esteemed nor carefully safeguarded. In such societies no restraint is imposed on the sexual impulse, which is gratified without shame and without formality. No hindrance is offered to the mutual intercourse of the two sexes. Chastity in the females is not prized by the males, nor do the latter compete for the favors of the former. Procreation is no more than a gregarious impulse of the masses among whom the common ownership of all booty is a matter of tribal custom. The woman has no disposing power over that which every one desires and which every one has the right to demand. Very gradually, however, a change takes place in this respect, so that in every period of social life since the very earliest, the modesty of young girls, the high valuation put upon the preservation of virginity, the ethical approbation of chastity in the wife, respect for the duties and rights of the mother, the reverence felt for the matron—all these, throughout the sexual life of woman, have had a civilizing, ennobling, and elevating effect. Thus, as family life has become developed, and as love and marriage have been more highly esteemed, woman has become the much-prized embodiment of all that is beautiful and good, of all that is summed up in the idea of the “housewife,” and her sexual life has been more completely, more ideally admired. The danger is not remote, however, that the leveling tendencies of the present day, and an inclination to despise the sexual life of woman, far from resulting in a further elevation of the social status of womanhood, will result rather in its abasement.

The Bible, as we may expect from the patriarchal relationships of the women of that time, bears witness to the worth of woman, and, whilst esteeming child-bearing, refers to yet higher duties. Precise religious and social precepts are furnished for all the phases of sexual life.

In classical antiquity, also, we see that woman rose to some extent above the low position she had previously occupied in the family circle and in society at large. Both among the Greeks and among the Romans, there was open to women a more intimate place in social life and a more influential rôle in the life of the family, than would have been their portion regarded merely in relation to their child-bearing activity. Amongst the Germans in the very earliest times, chastity gave rise to purer and more moral sexual relations; whereas among the Slavonic peoples the conception of woman as the childbearer continued to dominate these relations.

In consequence of the diffusion of Christianity, woman became man’s companion and equal, and her life, the sexual life included, acquired a deeper significance, owing to the stress which that religion laid on chastity as a virtue, and as a result of the educational influence of woman in the family circle.

With the progress of civilization the sexual life of woman comes to exhibit its activities only within the bounds of morality and law, which in human society have replaced the crude rule of nature, and have supplied regulations adapted to the changing phases of sexual vital manifestations. The wise adaptation of these regulations requires, however, a full understanding of the mental and physical processes, an exact recognition of the bodily states and intellectual sensibilities, of woman regarded as a sexual being.

Modern culture and the social organization of the present day, in association with the resulting sexual neuropathy of women, have exercised on their sexual life an influence as powerful as it is unfavorable, manifesting itself in the overpowering frequency of the diseases of women. In one of the most thoughtful books ever written on the subject of woman, Michelet’s L’Amour,[^[13]] the author remarks that every century is characterized by the prevalence of certain diseases: thus, in the thirteenth century, leprosy was the dominant disease; the fourteenth century was devastated by bubonic plague, then known as the black death; the sixteenth century witnessed the appearance of syphilis; finally, as regards the nineteenth century, “se siècle sera nommé celui des maladies de la matrice”.[^[14]] It is certain that the education and mode of life of the modern woman belonging to the so-called upper classes are, as far as sexual matters are concerned, in direct opposition to those that are agreeable to nature and those that the laws of health demand.

Even before sexual development begins, before the physical ripening of the reproductive organs to functional activity, the imagination of young girls is often prematurely occupied with sexual ideas in consequence of unsuitable literature, owing to visits to theatres and exhibitions, or on account of social intercourse with young men who are not overscrupulous in the selection of topics for conversation. From the time of puberty up to the time of marriage the growing woman is under the influence of the now awakened sexual impulse, which experiences ever-renewed stimulation. A sedentary mode of life, unsuitable nutriment, and the early enjoyment of alcoholic beverages, exhibit their inevitable result in the frequency with which, in this epoch of the sexual life, chlorotic blood-changes, neurasthenic conditions, and diverse symptoms of irritation of the genital organs, make their appearance. Thus, when marriage, so often unduly postponed in consequence of the condition of modern society, does at length take place, it is apt to find the woman not only fully enlightened as regards sexual matters, but often in a state of nervous weakness from sexual stimulation, one of the type whose characteristics have been happily summed up by the French writer Prévost in the expression demi-vierge.[^[15]] The conjunction of this state of affairs in the bride with the frequent partial impotence of the bridegroom, who has already dissipated the greater part of his virile power before entering upon marriage, leads often to the appearance of vaginismus and other sexual neuroses in young married women. Even more disastrous in its consequences as regards the future sexual life of the wife is the ever-increasing frequency of gonorrhœal infection in the first days of marital intercourse, with all the evil results of that infection. On the other hand, an ever-larger proportion of girls belonging to the “middle and upper classes,” abstaining alike from the good and the evil results of marriage, falls under the yoke of sexual impulses denied satisfaction or gratified by abnormal means, and suffers in consequence both physically and mentally. Further sources of injury arising from the conditions of modern social life are to be found in the neglect by women of the well-to-do classes of the duty of suckling their children, and in the ever-increasing frequency with which the women of these classes, after giving birth to one or two children, resort to the use of measures for the prevention of pregnancy, which result in serious consequences as regards both the nervous system and the genital organs of the women concerned. Thus there comes an accelerated ebb in the sexual life, leading to a premature appearance of the general phenomena of senility, with a cessation of the menstrual flow. The modern wife, who claims the right to lead the life that best pleases her, will be more rapidly overtaken by sexual death.

For the elucidation of the manifold reflex and other processes which are dependent upon or accompany the sexual phases of woman, we must in the first place consider the anatomical changes and physiological functions of the female reproductive organs characteristic of the several periods of sexual life which have already been distinguished. We must not fail also to take into consideration the mental states which accompany and characterize these respective phases.

The anatomical changes which occur in the female genital organs during these different phases of sexual life give rise to a number of manifold local stimuli, increasing and decreasing, varying greatly in intensity and area of distribution, upon which depend the reflex effects and remote manifestations in the sphere of the nervous and circulatory systems.

We must first consider the changes in the ovaries, which play an etiologically important part. At the onset of puberty, the follicular masses of the ovary exhibit a more active growth, the follicles increase in size, with their contained ova they approach the surface, and finally, by the bursting of the follicles, the ova are extruded. Then, in the life-phase in which conception occurs, and under the influence of the hyperæmia of all the pelvic viscera that accompanies this process, a notable development of the corpus luteum takes place, this latter body reaching its maximum size in the eleventh week of pregnancy, subsequently undergoing involution and leading to the formation of a considerable scar. Finally, in the critical period of life in which the menstrual flow ceases, a continually increasing growth and new formation of connective tissue-stroma takes place in the ovaries at the expense of their cellular constituents, and a regressive metamorphosis of the graafian follicles occurs.

In association with these sexual processes there ensues a series of striking changes in the shape and consistency of the ovaries, affecting both the surface and the parenchyma of these organs, and capable of stimulating the nervous ramifications in their tissue. In this connection it is worthy of note that the branches supplying the ovaries from the spermatic plexuses of the sympathetic contain a considerable proportion of sensory fibres.

Quite as significant, moreover, as the changes in the ovaries, are those which, in the course of the sexual life, the uterus undergoes, in shape and size, in its muscular substance and mucous lining, and in its vascular and nervous supply.

At the time of puberty the infantile uterus undergoes changes affecting both its external form and the shape of its interior cavity. The body of the uterus enlarges to the size characteristic of sexual maturity, and its mucous membrane becomes the seat of periodic changes. This waxing and waning growth and transformation of the uterine mucous membrane continues throughout the period of menstrual activity, the most superficial layers of the membrane being shed during menstruation, a process followed by regeneration, which is itself succeeded by the premenstrual thickening. When conception occurs, still more extensive changes ensue, the fertilized ovum becoming imbedded in the uterine mucous membrane, and the pregnant uterus, in shape and structure and in the respective relations of the body and neck of the organ, in the increasing distension of its veins and the increasing size of its nerves, becoming adapted to the important functions it has now to fulfil. When these have been fulfilled, and, parturition having taken place, the uterus is empty once more, the organ again adapts itself to altered circumstances by the process of involution. Later, in the climacteric period, a slow regressive process occurs, the outward manifestation of which is the cessation of the menstrual flow, characterized anatomically by atrophy of the muscular tissue of the uterus and of its vascular apparatus, by the dessication of its mucous membrane, by obliteration of the lumen of the uterine cavity, and ultimately by senile degeneration and atrophy of the now entirely functionless organ, so that it becomes an insignificant, cicatrized, solid body.

Next to the ovaries and the uterus, it is the pelvic fascia which in its entire architectonic structure as well as in its individual parts undergoes the most notable changes in consequence of the processes of generation.

A short account of the nerves and blood vessels of the female genital organs appears indispensable, to facilitate the comprehension of the manner in which sexual processes are influenced by the nervous system, and to demonstrate the intimate connection between the blood-supply of the genital apparatus and the general circulation.

The complex nervous network of the female sexual organs is supplied by spinal as well as by sympathetic fibres, the fibres from the two systems anastomosing in a very intimate manner.

Fig. [3].—The distribution of the pudic nerve, n. pudendus, in the female perineal and pubic regions. The trunk of the pubic nerve, n. pudendus, is covered by the gluteus maximus muscle. On the right side of the body the branches of the inferior pudendal nerve, rami perineales, nervi cutanei fermoris posterioris have been dissected out; but the branches of this nerve to the labium majus have been cut short. The formation of the anococcygeal or subcaudal nerves, nn. anococcygei, out of the posterior primary division of the coccygeal nerve and out of the perforating branches which arise from the anterior primary divisions of the fourth and fifth sacral nerves and the coccygeal nerve. (From Toldt: Atlas of Human Anatomy.—Rebman Company, New York.)

The greater number of the spinal nerves distributed to the genital organs arise from the lumbar portion of the spinal cord, pass as rami communicantes to the first four lumbar ganglia of the great sympathetic cord, whence they proceed to the series of symmetrical (paired) and asymmetrical (azygos) sympathetic plexuses in front of, and adjacent to the abdominal aorta, which already contain afferent and efferent spinal fibres derived from the pneumogastric, phrenic, and splanchnic nerves. A small number only of coarse nerve-filaments, a larger number of fine nerve-filaments, derived from the sacral nerves, proceed direct to the internal genital organs; many of these fibres enter the lower extremity of the pelvic or inferior hypogastric pleans, some pass to the cervical ganglia of the uterus. Below the bifurcation of the aorta and in front of the sacral promontory, a large number of the uterine nerves, both of spinal and of sympathetic origin, unite to form an azygos plexus which has been shown by experiment to possess great functional importance. Anatomically this constitutes the upper undivided portion of the hypogastric plexus, which is the downward continuation of the abdominal aortic sympathetic plexus; but inasmuch as it is the principal channel of nervous impulses to the uterus it is often known at the present day as the great uterine plexus (plexus uterinus magnus). The nerves to the ovary and Fallopian tube (ovarian nerves) are derived from the spermatic (ovarian) plexus, an offshoot of the renal plexus; as the spermatic plexus descends, it is reinforced by branches from the abdominal aortic plexus, these branches often arising from a small ganglion (spermatic ganglion). The hypogastric or great uterine plexus, single and median above, divides below into the paired pelvic or inferior hypogastric plexuses, which pass downward and forward on either side of the rectum; these plexuses are reinforced by spinal elements derived from the sacral nerves. Before the terminal expansions of the pelvic or inferior hypogastric plexus enter the tissues of the internal genital organs, the bladder, and the rectum, small masses of ganglionic matter are interspersed among the nerve fibres.

To the above general sketch, which has been based on the synoptical description of Chrobak von Rosthorn, must be added a more detailed account of the innervation of the ovaries, this branch of the subject being of especial importance. The nerves of the ovary are derived from the sympathetic system, in part from the spermatic ganglion, in part from the second renal ganglion, and in part from the superior mesenteric plexus. The nerves of the ovary are for the most part vascular nerves, which unite before entering the ovary to form the ovarian plexus, and then pass into the hilum with the vessels, envelop the vessels of the medullary layer, and thence pass to the follicular region; exceedingly numerous, they form a close-meshed network, surrounding all the vessels up to the finest capillary ramifications; those fibres which terminate in the capillary walls and those also which reach the follicles are regarded by Riese as sensory. The great trunks of the uterine nerves are transversely disposed in relation to the great lateral vessels of the uterus, and passing inward toward the mucous membrane they break up into pencils of filaments; the uterine nerves proper are distributed for the most part to the muscular substance. In the Fallopian tubes, the nerves form arches around the lumen of the tube; some fibres also pass to the longitudinal folds of the mucous membrane.

This expansion of the nerves of the cerebrospinal and sympathetic systems in the female reproductive organs manifests the multiple interconnection of the two systems in this region, and proves beyond doubt that the sensory nerves of the genital organs have manifold connections with the motor tracts of the whole organism on the one hand and with the sensory ganglia of the central nervous system on the other, and in addition with the vasomotor centres and with efferent motor and secretory fibres.

As regards the vascular system of the female genital organs, the latter are supplied by the internal iliac artery. One of the two terminal branches of the common iliac, the internal iliac artery, descends into the pelvis over the sacro-iliac synchondrosis. Its branches may be arranged in four groups: anterior group, the hypogastric, iliolumbar, and obturator arteries; posterior group, the lateral sacral, gluteal, and sciatic arteries; internal group, the inferior vesical, uterine, and middle haemorrhoidal arteries; inferior group, comprising a single artery only, the internal pudic; the uterine artery supplies the uterus and the vaginal fornices; the ovarian artery supplies the ovary, the Fallopian tube, and the broad ligament of the uterus; the vaginal, cervicovaginal, or vesico-vaginal artery supplies the vagina; the internal pudic artery supplies the vestibule and the clitoris; the superior and inferior external pudic arteries (branches of the femoral artery) supply the labia majora. The veins of the female genital organs correspond in general to the arteries in their course and nomenclature, and empty their blood into the internal iliac vein.

Fig. [4].—The distribution of the lateral sacral arteries, the superior haemorrhoidal or superior rectal artery, the uterine artery, the ovarian artery and the distal portion of the internal pudic artery. (From Toldt: Atlas of Human Anatomy.—Rebman Company, New York.)

Attention must also be paid to the extremely rich lymphatic vascular system of the female genital apparatus. The body of the uterus and the annexa of that organ, the neck of the uterus and the vaginal fornices, the middle segment of the vagina, the lower segment of the vagina, the vestibule and the external genital organs—each of these possesses an independent set of lymphatic vessels, leading moreover to independent groups of lymphatic glands. It may be said that the lymph from the vulva passes to the inguinal glands, that from the vagina and the neck of the uterus to the internal and the external iliac lympathic glands, that from the upper part of the uterus and also that from the ovaries and Fallopian tubes to the median group of lumbar lymphatic glands (also known, from their position in front of the aorta and the vena cava, as the aortic lymphatic glands) (Chrobak von Rosthorn).

The important influence which the genital processes exercise on the female organism as a whole is established not only by the anatomical relations just described but also by a number of physiological investigations and experiments and by the result of operations on the female genital organs.

Thermic and mechanical stimulation of the female genitals has, as my own experiments have shown, a notable influence on the heart and the general circulation. In these experiments, when uterine douches were given at temperatures of 4° C. (39° F.) and 45° C. (113° F.), the reflex nervous impulse which resulted from these manipulations had a two-fold influence on the circulation, manifesting itself first by an immediate and considerable augmentation in the functional activity of the heart, the frequency of which was increased in a degree proportional to the nervous sensibility of the individual, and secondly by a notable rise in blood pressure.

With a view to determining the influence of stimulation of the ovary on blood-pressure, Röhrig carried out some experiments on bitches, from which it appeared that electrical stimulation of the ovary invariably produced a remarkable increase in the general blood-pressure, an increase ranging from twelve to twenty-four millimeters of mercury. It further appeared in the course of these experiments that toward the end of the period of stimulation the rise in blood-pressure was always followed by a decline; to which, however, a renewed rise of blood-pressure succeeded after the stimulation was discontinued, provided the duration of this had not been excessive. Only after this second rise was the normal mean blood-pressure regained. Finally it was established that the pronounced phenomena of vagus-irritation exhibited by the curve during and immediately after the stimulation of the ovary were invariable concomitants of the rise of blood-pressure produced by such stimulation.

According to the observations of Federns, the blood-pressure undergoes a rhythmical change between one menstrual period and the next, the pressure curve being normally at its lowest at the time of the commencement of the flow, and at its highest at some time during the two days immediately preceding the flow. This rhythmical change of blood-pressure manifests itself also some time before the first onset of menstruation, when the approach of puberty is indicated only by the menstrual molimina.

Observations made by Kretschy in a patient with a gastric fistula have proved the influence exercised on gastric digestion by the physiological processes occurring in the female reproductive organs. In this patient, his attention was especially directed to determining at what period of digestion the secretion of acid by the stomach attains its maximum, and how that secretion increases and diminishes. He observed that the digestion of breakfast was completed in four and one-half hours, the acid-maximum occurring in the fourth hour, and the reaction of the gastric contents becoming neutral one and one-half hours later. This apparently constant acid-curve began, however, to become irregular as soon as the first symptoms of the approach of menstruation became apparent. When the flow had actually begun, he found that the reaction of the gastric contents remained acid throughout the entire day. As soon as the flow was over, the normal acid-curve was immediately reëstablished.

These observations have been confirmed by Fleischer. This investigator carried out his researches in menstruating women with normal stomachs, and found that with the appearance of the catamenia the process of digestion was almost always notably retarded, but that with the diminution and cessation of the flow digestion returned to the normal.

By stimulation of the central segment of the divided hypogastric or great uterine plexus, Cyon was able to provoke vomiting, a confirmation of the well-known physiological fact that irritative disturbances of the female reproductive organs have a reflex influence on the vomiting centre.

It is also clearly established that diverse stimulation of peripheral nerves, those for instance of the mammary gland, of the internal genitals, or of the epigastrium, is capable of affecting the motor centre of the uterus.

Worthy of note also are Strassmann’s experiments, showing that rise of pressure in the ovary causes swelling and structural changes in the uterine mucous membrane.

Striking also are Neusser’s discoveries that during menstruation there is an increase in the eosinophil cells of the blood, and that by the intermediation of the sympathetic nervous system the ovaries exercise an influence on the hæmatopoietic function of the red marrow of the bones. Most noteworthy is the connection between the functional activity of the ovaries and osteomalacia. In this disease of metabolism we have to do, according to Fehling’s now generally accepted assumption, with a trophoneurosis of the bones, a stimulation of the vasodilator nerves of the osteal vessels, dependent on a reflex impulse from the ovaries. The connecting path between the ovaries and the bones Neusser finds in this case also in the sympathetic nervous system.

The reflex influence exercised on the heart and the general circulation has been shown also by the results of operations on the female genital organs. In cases in which the ovaries have been removed, or in which these organs have been roughly handled, Hegar has noticed a great diminution in the frequency of the pulse, sometimes even cessation of the heart’s action. In similar circumstances Champonière also observed as a rule diminished frequency of the pulse, but in some cases increased frequency. Mariagalli and Negri have described tachycardia following laparotomy and the extirpation of double pyosalpinx. Bonvalot has published cases in which, in consequence of vaginal or intra-uterine injections, in consequence of simple examination, and in consequence of the performance of version, sudden death has resulted from cardiac syncope.

The psychical influences which proceed from the female genital organs in the different periods of sexual life have also great significance for the organism as a whole. Manifold impulses both stimulating and depressing arising in the reproductive organs affect the workings of the mind. The maiden at puberty is affected by the knowledge of sexuality; the sexually mature woman, by the desire for sexual satisfaction, and by the yearning for motherhood; the wife, by the processes of pregnancy, parturition, and suckling, or, on the other hand by the distressing consciousness of sterility; the woman at the climacteric period, by the knowledge of the disappearance of her sexual potency. The mind is further sympathetically influenced by the stimulation of the terminals of the sensory nerves in the genital organs. Through the increase of such stimulation, through its spread to adjacent nerves and nerve tracts and to the entire nervous system, the mind is affected, directly by irradiation, or indirectly by vasomotor processes and spinal hyperæsthesia.

Psychical manifestations and the nervous states associated with these are somewhat frequently, and even actual psychoses occasionally, encountered in the various phases of the sexual life of woman, sometimes taking the form of violent sexual storms, which may indeed, as ordinary menstrual reflexes, accompany every catamenial period.

Of great interest are the facts which have, in recent times especially, been scientifically established, pointing to a certain periodicity, to an undulatory movement of the general bodily functions of the female organism, dependent upon the sexual life. The observations of Goodman, Jacobi, von Ott, Rabuteau, Reinl and Schichareff, have shown that in woman the principal vital processes pursue a cycle made up of stages of increased and diminished intensity, and that this periodicity of the chief general processes of vital activity finds expression also in the functions of the reproductive organs. Goodman has compared this play of general vital functions to an undulatory movement. According to this writer, a woman’s life is passed in stages, each of which corresponds in duration with a single menstrual cycle. Each of these stages exhibits two distinct halves, in which the vital processes are respectively ebbing and flowing: in the latter we see an increase of all vital processes, a larger heat production, a rise in blood-pressure, and an increased excretion of urea; in the former we see, on the contrary, that all these vital processes display a diminished intensity. The moment when the period of increased vital activity is at an end, the moment when the ebb begins, corresponds, according to Goodman, to the commencement of the catamenial discharge.

Goodman sought for verification of this undulatory theory of the sexual life of woman in certain data regarding the bodily temperature and the blood-pressure. A more extensive research was undertaken by Jacobi, who, as the result of her observations, came to the following conclusions. In eight cases she noticed in the premenstrual epoch a rise of temperature ranging from 0.05° C. to 0.44° C. (0.09° F.–0.79° F.); and during the catamenial discharge a gradual fall of 0.039° C.–0.25° C. (0.072° F.–0.45° F.), never less, that is to say, than a quarter of a degree Centigrade; but in the majority of cases the temperature did not, while the catamenia lasted, regain the normal mean. She further observed in the generality of cases an increased excretion of urea during the premenstrual epoch; and a notable fall in blood-pressure during menstruation.

Reinl’s observations on healthy women, in whom menstruation ran a normal course, showed that in the great majority of cases in the premenstrual epoch the temperature was elevated as compared with that of the interval, that in eleven out of twelve cases the temperature gradually declined during menstruation, to fall in three-fourths of the cases below the mean temperature of the entire interval, and exhibiting in the post-menstrual epoch a still further depression, giving place, however, to a somewhat higher mean temperature during the first half of the interval. In the second half of the interval a higher mean temperature was observed than in the first half.

If we make a graphic representation of the mean differences in temperature commonly observed throughout the various stages of an entire menstrual cycle, we see that the curve does in fact take the form of a wave. That drawn by Reinl is shown in the following figure: (Fig. [5].)

Fig. [5].

The rising portion of the wave, the beginning of the tidal flow, corresponds to the second half of the interval; the height of the tidal flow, the crest of the wave, corresponds to the premenstrual epoch. As the flow gives place to the ebb, as the wave begins to decline, we come to the actual period of the catamenial discharge; later in the ebb is the post-menstrual epoch, and the lowest portion of the declining wave corresponds to the first half of the interval. Rhythmic changes corresponding to those observed in the temperature have been recorded—at least in isolated stages of the menstrual cycle—affecting the blood-pressure by Jacobi and by von Ott, affecting the excretion of urea by Jacobi and by Rabuteau, and affecting the pulse by Hennig. It is evident that the vital activity of the organism attains its maximum shortly before menstruation; and that with or immediately before the appearance of the catamenial discharge, a decline of that activity commences.

Schrader, through his researches on metabolism during menstruation in relation to the condition of the bodily functions during this process, has established that immediately before menstruation the elimination of nitrogen in the fæces and the urine is at its lowest, a fact which indicates that at this period of the menstrual cycle the disintegration of albumen in the body is notably diminished.

Von Ott found in thirteen cases out of fourteen that at the beginning of the catamenial discharge or just before a considerable fall in blood-pressure occurred, and that throughout the flow the pressure almost always remained below the mean, no rise taking place till menstruation was finished; this fall in blood-pressure during menstruation was more considerable than could be accounted for by the moderate hæmorrhage. The same author, in conjunction with Schichareff, examined fifty-seven healthy women in respect of heat-radiation, muscular power, respiratory capacity, expiratory and inspiratory power, and tendon-reflexes. He found that the energy of the functions of the female body increased before the beginning of menstruation, but declined with or immediately before the appearance of the catamenial discharge. He exhibited this rhythmical variation in the vital processes by means of the following curve, in which the line A B represents these physiological variations, whilst on the abscissa line c e, the days of observation are recorded, and the interval m n represents the menstrual period. The degree of intensity of the united functions is indicated by the numbers 0–100 on the ordinate.

Still another point of view from which the influences affecting the female organism as a whole may be regarded has very recently become apparent in consequence of the doctrine of Brown-Séquard relating to the internal secretions of ductless glands. As regards the female reproductive glands, which in consequence of their structure must be referred to the group of ductless glands, and yet owing to their secretory function must be classed among secreting glands (so that the nature of the ovary is that of a secreting gland without an excretory duct), it would appear that these glands are not concerned only with the specific female reproductive functions of menstruation and ovulation, but that they also exercise a powerful influence on the nutritive processes, on metabolism and hæmatopoiesis, and on growth and development in their mental as well as their physical relations.

It is supposed that these glands under normal conditions enrich the blood with certain substances, which in part assist in hæmatopoiesis, and in part by regulating the vascular tone in the various organs are concerned in the normal processes of assimilation and general metabolism. According to Etienne and Demange, ovariin possesses an oxidising power similar to that possessed by spermin. Thus it becomes easy to understand how disturbances in the functions of the ovaries give rise to disturbances in the processes of general metabolism and of assimilation. Some go even further, though in doing so they leave the ground of assured fact, suggesting that the ovary in certain circumstances produces toxins, or that the normal ovary possesses an antitoxic function, and speaking of an occasional ovarian auto-intoxication of the body or of a menstrual intoxication. Thus, chlorosis is by some regarded as a disturbance of hæmatopoiesis, dependent on an abnormal condition of the female reproductive organs during the period of development, and referable to a disturbance of the internal secretion of the ovaries (Charrin, von Noorden, Salmon, Etienne, and Demange). And it is now generally assumed, the assumption being based on the observations recently made concerning the organo-therapeutic employment of the chemical constituents of the ovary, that many of the disorders, and especially those connected with the vasomotor system, common during the climacteric period, are dependent on the deficiency of the products of the internal secretion of the ovary that accompanies the cessation of the menses.

Recent experimental investigations on this subject have shown that the interconnection between the female genital organs and the organism as a whole, between the functions of the reproductive organs and the functions of other organs, does not depend on nervous influences only, but that in this interconnection the blood vascular system and the lymphatic vascular system also play their parts. Goltz has proved by actual experiment that the nervous influence on menstruation and ovulation is not the only determinant. In a bitch, he divided the spinal cord at the level of the first lumbar vertebra, and observed, as soon as the animal had recovered from the operation, the appearance of the usual signs of heat; the bitch was impregnated, and gave birth to one living and two dead puppies; lactation and sucking took place as in a normal animal. When the bitch was killed and the body examined it was found that no reunion had taken place in the severed spinal cord. The experiments of Halban gave similar results. He found that in apes, if the ovaries are removed from their normal situation and successfully transplanted to some region remote from the genital organs, the animals remain capable of menstruating. But if the ovaries, which have been transplanted beneath the skin or beneath the peritoneum, are subsequently entirely removed, menstruation, which has continued regularly after the first operation, ceases altogether after the second. It follows from these experiments that the cessation of the menstrual process may be considered to be brought about through the intermediation of the lymphatic or blood-vascular system, by the absence of a kind of internal secretion.

Loewy and Richter have further proved by experiment that in spayed bitches the consumption of nitrogen is less by about 20 per cent. and the entire gaseous interchange less by about 9 per cent., as compared with what takes place in normal animals, and that this change in respiratory metabolism lasts for a long time after the oöphorectomy, for as much as nine to twelve months. If dried ovaries are given to such animals in their food, the gaseous interchange rises to the former level and even higher.

The undulatory movement of the vital processes in woman is apparently in some way dependent on ovulation, though the nature of the connection has not hitherto been fully elucidated. This view is confirmed by the fact that no such rhythmic variation in the bodily functions can be detected either in girls under thirteen years of age, or in women from fifty-eight to eighty years of age in whom menstrual activity has entirely disappeared. The menstrual rhythm begins at puberty and ends when ovulation ceases.

A further contribution to the doctrine of the undulatory movement of the vital processes in woman is to be found in my own observations that pathological symptoms which have become manifest before and at the time of the first onset of menstruation, and have given but little trouble throughout the period of developed and regular sexual activity, are apt when menstruation ceases to recrudesce, and to become as prominent as they were at the commencement of the sexual life. Women who at the time of puberty suffered from cardiac troubles, from digestive disturbances, or from various forms of nervous irritation, and in whom as they grew up these disorders passed more or less into abeyance, are apt at the climacteric period to exhibit, as I have frequently been able to observe, a violent return of these symptoms, in the form, as the case may be, of tachycardia, of dyspeptic troubles, or of psychoneuroses. In this connection we may mention an observation of Potain’s, who distinguishes a peculiar form of chlorosis, occurring in individuals of delicate constitution, which, though apparently cured, reappears at the menopause.

Related to the sexual life of woman is another attribute, one intimately connected with the idea of the female sex, and one which since the primeval days of humanity has filled men with delight and poets with inspiration—the attribute of beauty.

The beauty of woman, a prominent secondary sexual character, makes its first appearance at puberty, when the girl’s form, hitherto undifferentiated in its external bodily configuration, begins to assume a soft and rounded appearance, when the features become regular, the breasts enlarge, and the pubic hair begins to grow—when, in short, to the primary sexual characters already existing, the secondary sexual characters are superadded.

Feminine beauty continues to increase until the attainment of sexual maturity. In her third decade woman arrives at the acme of her sexual life and at the same time attains the perfection of her beauty.

The ensuing sexual phases, pregnancy, parturition, and lactation, entail a decline in beauty, not rapid indeed, but advancing gradually, with the slow yet sure-footed pace of time. The organic revolutions accompanying these processes leave traces recorded upon the surface of the body in conspicuous and indelible characters. The illnesses, also, which so often accompany the fulfilment of sexual functions, in injuring health impair also beauty.

A woman who has given birth to and nursed an infant begins to lay on fat, and this tendency to obesity becomes more pronounced as the climacteric period approaches. The breasts become inelastic and pendent, the abdomen becomes ungracefully prominent; the tonicity of the entire organism gradually declines, and, in consequence of the loss of elasticity in the subcutaneous cellular tissue, the dreaded wrinkles make their appearance and the features become wizened. Beauty is a thing of the past. With the cessation of the sexual life the external secondary sexual characters disappear, and the old woman is even farther removed than the old man from our conception of beauty.

As Mantegazza insists, the beauties peculiar to women are one and all sexual; they depend, that is to say, upon the peculiar functions that nature has allotted to woman in the great mystery of procreation. One of the most vivid and poetical descriptions in ancient or modern literature of these secondary sexual characters on which feminine beauty depends is to be found in the Song of Solomon.

In the following figure (Fig. [7]) the curve of beauty of woman is given as drawn up by Stratz. In one case it may rise very quickly, to decline with equal quickness—the so-called beauté du diable;[^[16]] in other cases, again, the curve rises very slowly, and declines also very slowly, the culmination of the curve being in this case attained later, and when attained being absolutely higher, than in the case of the steeper curve.

Fig. [7].

The age at which the maximum of beauty is attained is a very variable one. In the southern races this often occurs as early as the fourteenth or fifteenth year of life; but in the peoples of the Teutonic stock, Germans, Dutch, Scandinavians, and English, not as a rule before the twentieth year, and it may be even later. Stratz has known cases in which women did not attain the prime of their beauty until the thirtieth and even the thirty-third year. The same author, a most competent authority as regards the subject of feminine beauty, affirms that a beautiful woman is most beautiful when the period of maximum beauty coincides in her case with the first month of her first pregnancy. With the commencement of pregnancy the processes of nutrition are accelerated, all the tissues are tensely filled, the skin is more delicately and at the same time more brightly tinted owing to the greater activity of the circulation, the breasts become firmer and more elastic. Thus the attractive characteristics of beauty at its fullest maturity become enhanced, but for a short time only, since the enlargement of the abdomen in the further course of pregnancy impairs the harmony of the figure. Finally we must point out, before dismissing this subject, that women of the so-called better classes arrive as a rule at maturity later, and remain beautiful for a longer period, than women of the working classes.

The degree to which the female organism as a whole is influenced by the processes of the sexual life that occur in the genital organ depends upon many of the characteristics that combine to make up the individuality. Inherited characteristics, temperament, and race, play a great part in this connection; and not less important than these are the social conditions, the environment, in which the women under consideration pass their life. Thus, among women belonging to the poorer, labouring classes, the reflex manifestations in other organs dependent upon the processes of the genital organs are less frequent and less intense than among women belonging to the well-to-do strata of society and to the cultured classes; less also in the country than in large towns. In phlegmatic individuals, such manifestations exhibit less intensity than in those of an active, ardent temperament; they are less frequent in persons with a powerful constitution than in those endowed by inheritance with an unstable nervous system. Finally, they are less often encountered among families whose upbringing has aimed at hardening the constitution and at inculcating the control of instinctive impulses, than among those in whom from early childhood sensibility and impulsiveness have been given a loose rein.

Extremely variable also are the sympathetic disturbances and morbid states which depend on the processes of the sexual life of woman. “Le cri de l’organe souffrant ne vient pas de l’utérus, mais de tout l’organisme,”[^[17]] says Courty. And a large number of isolated observations has shown how complex are the relations between the healthy and unhealthy female genital organs and the other organs of the body as well as the organism as a whole. Precise and incontestable proofs exist of such relations between the female genital organs and morbid changes in the eye and ear, the skin, the respiratory organs, and the vascular and nervous systems.

The influence exercised by the reproductive system on the general vital processes of woman is indicated also by the general statistics of mortality and the incidence of disease. Mortality in women, the earliest years of childhood being left out of consideration, is at its highest precisely during the great sexual epochs, namely at the time of puberty, during pregnancy, during the puerperium, and at the climacteric period. The complete performance of the reproductive functions entails a higher proportion of illnesses and death; and statistical records show that the mortality of married women between twenty and forty years of age, during the period, that is to say, in which in consequence of marriage they fulfil the duties of sexual intercourse and procreation, and are exposed to the dangers connected with these sexual acts, is much higher than the mortality of unmarried women of corresponding ages. Infection with the gonococcus and with the virus of syphilis, chronic salpingitis, metritis, and parametritis, the manifold diseases of pregnancy, the diseases of the puerperium, the various displacements of the uterus, osteomalacia—all these are pathological states the dependence of which upon the sexual life of the married or at any rate sexually active woman is indisputable. But the complete renunciation of sexual activity appears also to exercise an injurious influence on the health, and to give rise or at least predispose to morbid manifestations. Hysteria, for instance, chlorosis, uterine myomata, and various neuroses, have long been supposed to depend in part upon such renunciation, though the causal connection cannot be regarded as yet fully established.

Especially true as regards woman, indeed, is that which Ribbing says concerning the sexual life in general: “Since all human life and being has its origin in sexual relations, these sexual relations may be regarded as the heart of humanity. We may work day and night for the good of humanity, we may sacrifice for that good our time and our blood, but all this work and all this sacrifice appear to me to remain useless if we neglect and despise the sexual life, the eternally self-renewing elementary school of true altruism.”

From the vital phase in which, marked by the visible manifestations of puberty and by the first appearance of menstruation, ovulation is assumed to begin, the sexual life of woman continues to the period of life in which, marked by the climacteric cessation of menstruation, ovulation also ceases. The total duration of this sexual period in woman’s life is usually about thirty years; but it is subject to great variations, from six to forty-six years according to the available statistics, these variations depending upon climate, race, constitution, and the sexual activity of the person under consideration.

The duration and the intensity of the sexual life of woman depends upon a series of external conditions affecting the individual, but especially upon the inherited predispositions, upon the constitutional conditions, upon the varying vital power of the individual. My own observations have led me to formulate, as a general law, that the earlier a woman (climatic and social conditions being similar in the cases under comparison) arrives at puberty, the earlier, that is to say, that menstruation first makes its appearance, the greater will be the intensity and the longer the duration of sexual activity, the more will the woman in question be predisposed to bear many children, the more powerfully will the sexual impulse manifest itself in her, and the later will the menopause appear. It seems that in such women a more intense vitality animates the reproductive system, bringing about an earlier ripening of ova, a more favorable predisposition on the part of these ova to fertilization by the spermatozoa, a livelier manifestation of sexual sensibility, and a longer duration of ovarian functional activity.

My general views on this subject are embodied in the following propositions:

1. The duration of sexual activity is less in the women belonging to the countries of southern Europe than in those belonging to the countries of northern Europe. It would appear that in those climates in which ovulation begins sooner and menstruation first appears at an earlier age, the menopause also appears earlier; but that, on the contrary, in those climates in which puberty is late in its appearance, the decline of sexual activity is similarly postponed.

2. Women in our mid-European climates, in whom puberty appears at an early age, the first menstruation occurring between the ages of thirteen and sixteen, exhibit a more prolonged duration of the sexual life, of menstrual functional activity, than women in whom menstruation begins late, between the ages of seventeen and twenty. Extremely early appearance of the first menstruation—so early as to be altogether abnormal—has, however, the same significance as abnormally late onset of menstruation; both indicate that the sexual life will be of short duration.

3. Women whose reproductive organs have been the seat of a sufficient amount of functional activity, who have had frequent sexual intercourse, have given birth to several children, and have themselves suckled their children, have a sexual life of longer duration, as manifested by the continuance of menstruation, than women whose circumstances have been just the opposite of these, unmarried women, for instance, women early widowed, and barren women. Sexual intercourse at a very early age, however, accelerates the onset of the climacteric period and the termination of the sexual life. The same result follows severe or too frequent confinements.

4. The sexual life has a shorter duration in the women of the laboring classes and belonging to the lower strata of social life, as compared with upper class and well-to-do women. Bodily hardships, grief, and anxiety also hasten the onset of sexual death.

5. Women who are weakly and always ailing have a shorter sexual life than women who are powerfully built and always in good health. When irregularities and disorders have appeared in the various sexual phases, the decline of sexual activity occurs earlier than in women whose functions have in this respect been normal. Certain constitutional conditions, such as extreme obesity, certain acute diseases, such as typhoid fever, malaria, and cholera, and certain diseases of the uterus and its annexa, chronic inflammatory conditions for instance, bring about a notable shortening of the duration of the sexual life.

In 500 cases that have come under my own observation, the women concerned belonging to very various nationalities, the duration of the sexual life, as witnessed by the continuance of menstruation, was as follows:

Menstruation continued for:

Thus we see that the duration of the sexual life varies from 6 to 46 years. The most frequent duration is one of 32 years, next to this one of 29, next again, 31, 33, and 37 years, respectively. In 6 women only did the duration of the sexual life exceed 40 years, and in 4 only was it less than 11 years. In half of all my cases the duration of the sexual life was between 27 and 34 years, and from these figures we obtain an average duration of about 30 years.

For North Germany, Krieger gives data from which it appears that in this region the average duration of the sexual life is 30.49 years. In more than half of the 722 cases recorded by this writer the duration was between 31 and 37 years. In isolated cases the duration was very short, not exceeding 8, 9, or 10 years, or, on the other hand, as long as 47 years; whilst the number of cases increased fairly regularly up to the duration of 34 years, and thereafter again diminished.

As regards Austria, Szukits has collected information in the case of 269 women, and found, in these, that the duration of the sexual life varied from 12 to 45 years. The average duration was 29.16 years; in more than half of the women, the period of sexual activity lasted from 21 to 30 years; the shortest period observed was 12 years, the longest 45 years.

The period of sexual activity lasted:

In Poland, according to Raciborski, the duration of sexual activity is in Jewesses 23 years, but in women of Slavonic blood 31 years.

In France, according to Courty and Puech, the usual duration of the sexual life is from 28 to 30 years.

According to Puech, among 10 women menstrual activity lasted:

Brierre de Boismont gives the following particulars of the duration of menstrual activity in 178 Frenchwomen:

For England, Tilt gives the mean duration of menstrual activity, as observed in 500 women, as 31.21 years; it varies between 11 and 47 years; there are more cases with a period of 34 years than with any other integral number of years. Tilt found the duration to be:

For London the average figure is 34 years; for Paris, 30 years; for Vienna, 29 years; and for Berlin, 34 years.

From the data of various observers obtained from diverse nationalities, the following table has been compiled, exhibiting the mean duration of the sexual life:

In the temperate zone the sexual life of woman lasts longer than in the colder and subarctic regions. Still more favorable is the contrast between the temperate zone and the countries of the tropics, in which the duration of the period of menstrual activity is limited to eighteen or twenty years. According to some isolated observations the duration of sexual activity in Arabian women in Africa was as little as nine years.

A certain influence on the duration of the sexual life is exercised by the commencement of menstruation at an earlier or later age than the average. The total duration of menstrual activity is more variable in women who begin to menstruate early than in women who begin to menstruate late, in whom the duration of the sexual life is a more regular one. In those women who begin to menstruate early the mean duration of the sexual life is about thirty-three years, in those who begin to menstruate late it is about twenty-seven years.

The following data, based on the observation of 250 cases, are published by W. Guy, regarding the duration of the sexual life, that is to say of menstrual activity, in women beginning to menstruate early and those beginning to menstruate late, respectively:

A further analysis of these 250 cases is given by Guy in the following table:

Hannover also gives data respecting the relation between the duration of menstrual activity and the early or late appearance of menstruation. These data are tabulated as follows:

Totals: In 412 cases the average age at the menopause was 44.82, and the average duration of menstrual activity was 27.973 years.

From the tables of L. Mayer, Krieger has instituted a comparison between the duration of menstrual activity in 101 women who began to menstruate early and 180 women who began to menstruate late, finding in the case of the former a mean duration of 33.673 years, and in the case of the latter a mean duration of 27.344 years, showing therefore a sexual life longer on an average by 6.429 years in those in whom puberty was early as compared with those in whom puberty was late.

From the tables of Tilt, based on the observation of 164 cases, 76 women in whom menstruation appeared early and 88 in whom it appeared late, we learn that among the former the shortest duration of menstrual activity was 18 years, among the latter 12 years; among the former the longest duration was 37 years, among the latter only 33. The majority of those who began to menstruate early continued to menstruate for 28, 31, 32, 33, 34, 35, 36, 38, or 39 years; those who began to menstruate late, for 23, 27, 28, 30, or 31 years. The mean duration of the sexual life in those who began to menstruate early was 33.66 years; in those who began to menstruate late it was 28.28 years. Since the average duration of the menstrual function is given by Tilt as 31.33 years, those who began to menstruate early exceeded this average by 2.33 years, while those who began to menstruate late exhibited a duration of menstrual activity of at least three years less than the average.

In addition to climate, nationality, and the age at which menstruation begins, the sexual activity of women also exercises an influence on the duration of their sexual life, and of especial importance in this connection are the number of children born, and exercise or neglect of the function of lactation. From my own observations on this matter it appears, that in women who are healthy and of powerful constitution, whose reproductive organs have been sufficiently exercised, who have given birth to several children and have suckled these children themselves, the duration of menstrual activity is in general notably longer than in women whose circumstances have been just the opposite in these respects. Among the women in my own series of cases in whom menstrual activity lasted longest, of the 177 women in whom menstruation ceased between the forty-fifth and the fiftieth year of life, 1 only was unmarried, 2 were married but childless, 32 married with 1 or 2 children only, and 142 married and with more than 2 children; of the 89 women in whom menstruation ceased between the fiftieth and the fifty-fifth year of life, none were either unmarried or childless, 19 were married with 1 or 2 children, 17 married and with more than 2 children; of the 17 women in whom menstruation ceased later than the fifty-fifth year of life, there were 2 only with less than 2 children, but 10 who had each given birth to from 6 to 8 children. A similar influence is exercised by the function of lactation. Among 40 women who had not suckled their children, the average duration of menstrual activity was 4 years less than the general mean.

As regards the conditions of life, L. Mayer affirms that the duration of sexual activity among well-to-do women is on the average a year and a half longer than among women of the working classes.

Metschnikoff has drawn attention to the remarkable disharmony in the development of three of the phases of the sexual life of woman, inasmuch as the sexual impulse, the union of the sexes, and the capacity for procreation, which, considering their nature and purpose, might have been expected to be attuned so as to act in harmony, exhibit as a matter of fact no such relation; the different factors of the sexual function develop independently and unharmoniously. In a child not yet fitted to fulfil the function of procreation, the sexual impulse will none the less make its appearance, and be liable to misuse. In the girl the pelvis does not attain that complete development which fits it for the process of parturition until toward the age of twenty, whilst puberty occurs at the age of sixteen. “A girl of ten is capable of aspiring to play the part of a woman, but not before the age of sixteen is she fitted to play that part, nor indeed fitted to become a mother before the age of twenty.”

In general, we may say, regarding the women of our own part of the world, that in those who are healthy, who lead a regular life, are well fed, free from the pressure of anxieties, with their sexual functions sufficiently exercised, the duration of the sexual life is longer than in women whose circumstances are the reverse of those just enumerated. It is a sign of decadence when women of the well-to-do classes, leading a life of ease, manifest a diminished duration of the sexual life. The greatest physical power and the highest ethical development are associated with a lengthening of life in general, and associated also with a lengthening alike in the sexual life of woman and the sexual potency of man. A decline in morals and culture entails a diminution of sexual vital capacity, this being true alike of individuals, of families, and of nations. Woman is venerated and valued the more, the longer the duration of her sexual life; a woman in whom the sexual life is short quickly loses value and significance, both in domestic and in social circles.

The social significance of the sexual life of woman is disproportionately greater and farther reaching than the sexuality of the male, as the former is concerned with the fundamental principles of human social life, influencing the constitution of the family, and controlling the good of the coming race. Sexual purity, which to the youth is a romantic dream, is to the maiden a vital condition of existence; adultery, in the husband a pardonable transgression, is in the wife an overwhelming sin committed against family life. To the freedom of the male in affairs of love is opposed the strict restraint of the female, based on monogamic marriage. The sexual needs and desires of the female are transformed in an ideal manner by means of the feeling of duty of the wife and mother; the violent pressure of the sexual impulse is restrained by the opposition of ethical forces. When this restraint fails, the running off the rails that ensues has a far profounder influence in the case of the female than of the male, an influence not limited to her own personality, but dragging down the whole family into the abyss of consequences, into the depths of moral and physical destruction.

Though in nature everywhere the same, the sexual life of woman exhibits in the various gradations of social life different outward manifestations, from the brutal sexual congress that does not greatly shun publicity, to the modern would-be philosophical free love. And throughout all variations the two darkest points remain, the illegitimate child and venereal infection, both of which entail upon the woman the most unspeakable anxieties and the greatest possible misery, whilst the man who is in either case to blame passes comparatively unscathed.

The social sexual position of woman suffers most at the present day from the mature age at which under existing social conditions men are alone able to marry and from the ever-increasing number of cases of venereal infection. In both these directions social science and medical skill must work hand in hand for the amelioration of the sexual life of woman.

On the twentieth century falls the duty of furnishing a solution for these problems. Contesting voices are heard on all sides. Tolstoi’s rigid demand for complete sexual abstinence, the exhortation of the professors of the German universities to their students in favor of moral purity, the associations for the official prevention of venereal diseases, the agitation among young men in favor of abstinence from sexual intercourse before marriage, finally, the clamorous voices of the supporters of women’s rights—all these are influences within the sphere of sexual morality, which must lead slowly but surely to extensive social changes in the sexual life of women.

The discussion of the sexual life of woman, which for many centuries was concealed by a thick veil from the eyes of the profane, or was viewed only through the frosted glass of poetical metaphor, has in recent times assumed a quite revolting character. Not only have the acquired liberties and the social aims of the present day a tendency to give to women in general a freer and higher position, to emancipate them from the bonds in which owing to the conditions of family life they have so long been shackled, but some members of the women’s rights party go even farther, and demand for women greater freedom in the sphere of sexual activity.

With this end in view the sexual life of woman is used as the fulcrum of the lever, and is withdrawn from the twilight into the open light of day, or indeed too often into a dazzling and altogether false illumination. Women writers especially, who have hitherto been accustomed to delude themselves and the world with sensational representations of the feminine soul, of feminine modesty, and the fineness of feminine sensibility in matters sexual, now find their greatest joy in unveiling themselves and their sisters before the face of all the world, and in discussing in the plainest language the most intimate processes of the genital organs. In writings exhibiting but little good taste, though all the more temperament, they emphasize again and again one side only of the sexual life, to wit, the sexual impulse, the force of which is intentionally exaggerated to a high degree, so that it is described as a mighty current of passion, which may with great pains be held in check for a season, but must ultimately break loose, and with devastating rage must overwhelm everything which has hitherto been regarded as discipline and good morals. Young girls, even, step down into the arena to take part in the contest concerning the reform that is to take place in the relations between men and women. Especially sensational in this connection was Eine für Viele. Aus dem Tagebuche eines Mädchens von Vera,[^[18]] a book which, totally ignoring the biological differentiation of the sexes and their diverse sociological course of development, goes so far as to insist that from the man entering upon marriage, as from the woman, sexual purity and virginity are to be demanded. (The heroine of the book commits suicide because her lover has in earlier years had experience of sexual intercourse.)

From a mistaken standpoint other supporters of women’s rights oppose the ideal method in sex-relations, life-long monogamy, and the ideal of sexual sensibility, motherhood, and they put forward quite new sexual pretensions on behalf of women, as belonging to them by natural right. Upon these pretensions it is the duty of physicians, who truly know and truly prize womanhood, to pass their judgment, and that judgment, which will find ample justification in the ensuing descriptions of the individual phases of the sexual life of woman, is that the modern movement on behalf of the emancipation of women goes much too far. We do not, however, mean to imply that this movement is totally unjustified.

The growing girl must not, as has hitherto been the case, be kept in a state of ignorance (which is indeed in most cases apparent merely) regarding the sexual processes of her own body, she must no longer, when she asks to be informed concerning these matters, be put off with conventional lies and prevarication. But her enlightenment must not be effected in such a manner as to lead to excitement and excessive stimulation, to the awakening of slumbering feelings, and to the conversion of fantasy into a devouring flame. Sexual enlightenment must not be made an excuse for the unchaining of sensibility. When about to be married, a woman should certainly be instructed regarding her sexual duties and rights, and enter as one well informed into the act in which she is to play a leading part. But she ought not, with the excessive valuation of herself attained in recent times, to regard the man as her enemy, as one whom she is always justified in fighting and always ready to fight with the equal weapons of sexual transgression. It cannot be doubted that the ideal of “pure marriage” at an early age is one greatly to be prized as the foundation of a powerful future generation; but the real nature of the male must not be overlooked, nor must his sexual honor be put to too difficult a test. We regard as reasonable the modern demand of woman that in marriage her individuality should not be buried, and that space should be given for the development of her personality; but every sober-minded person will reject the “moral demand” for “ideal passion” in accordance with “entire mutual freedom” in the sexual relation between man and wife, and will regard such free love as social insanity and as a barbaric retrogression toward the rude sexual habits of savage peoples. Further, in view of the continually increasing intensity of the struggle for existence and in view of the difficulties of the task of rearing children, we cannot fail to recognize that it is not right for women to be overburdened with the task of reproduction, and that she does not live simply and solely for the bearing of children—but those rush to the other extreme who undervalue motherhood and the duties of maternity, who speak scornfully of the woman who is “a mother, and a mother only,” who despise women whom they regard merely as “means for the production of children,” and who employ all possible methods to free women from the pressing claims of nature and of society.

In all social circumstances, and in all times the great principle of sexual morality must dominate the sexual life of woman. As the ethical characteristics of the three great epochs in that sexual life we recognize the purity of the maiden, the faithfulness of the wife, and the love of the mother. But within the limits imposed by these demands it is still possible to satisfy the modern claim for a free development of the personality, and to accommodate the circumstances of the sexual life to the individual vital needs and vital claims of the present day.

I. THE SEXUAL EPOCH OF THE MENARCHE.

(PUBERTY.)

The term menarche (μήν, a month, ἀρχή, the beginning) was introduced by me into medical literature to denote the period of life in which, as a sign of puberty, menstruation first makes its appearance.

The age at which this occurs is subject to variations depending upon race, occupation, hereditary tendencies, and climate; but in Germany and Austria the average age at puberty is 14 or 15, the extreme limits being 12 to 19.

Until about the age of 13, the physical differentiation of the sexes, except for the anatomical peculiarities of the genital organs, is in our climates a trifling one. But at puberty the important changes occur by which the sexes are so strikingly differentiated. Whereas in the growing boy all physical change takes the form of increasing strength and energy, in the development of the girl, we note the appearances of the rounded outlines so characteristic of womanhood. At the same time the voice alters, becoming less sharp, with a softer quality, and yet a fuller tone; and we may observe that young brunettes have commonly a contralto voice, young blondes, more often a soprano. The intellectual changes undergone by the girl at puberty are no less extensive and characteristic than the physical changes. In brief, the undifferentiated, neuter girl is transformed into a young woman, endowed with all the attributes, mental and bodily, characteristic of femininity.

As regards the age at which the menarche usually occurs, and the manner in which its occurrence is anticipated or retarded by the various influences already mentioned, the following propositions may be put forward, based on the available statistics and observations:

1. Climate is an important factor. In the torrid zone, menstruation appears at a very early age, on the average from 11 to 14; in the temperate zone, it appears later, on the average from the age of 13 to 16; in the frigid zone, later still, on the average from the age of 15 to 18. The mean temperature of the atmosphere appears to have a direct influence on the age at which menstruation begins, the hotter the climate, the earlier being the menarche. The height of the place of residence above the sea level and its distance from the coast also have a certain influence.

2. Race and constitution have a distinct influence upon the age at which menstruation makes its appearance. In women of the Semitic races the menarche occurs earlier than in women of the Aryan races. The average age at which menstruation begins is in Jewish girls, from 14 to 15; in Magyar girls from 15 to 16; in German girls from 16 to 16½; and in Slavonic girls from 16 to 17.

In general the menarche is earlier in girls of a sanguine, lively temperament and a powerful constitution than in girls of a phlegmatic temperament and a weakly constitution; further, other things being equal, menstruation appears earlier in brunettes, girls with black hair, thick skin, dark eyes, and a dark complexion, than it appears in blondes, girls with light hair, thin skin, blue eyes, and a fair complexion.

3. The age at which menstruation begins is also affected by the conditions of life and the social circumstances. In the higher circles of society, in the upper, well-to-do classes, menstruation appears earlier than among women of the laboring classes, who are compelled to strive for their daily bread. Amongst upper-class girls the menarche occurs at the age of 14 in one-fourth of their number, whereas among lower-class girls barely one-sixth begin to menstruate at the age of 14.

In large towns, again, menstruation appears earlier than in small towns, whilst in the open country the menarche is still further delayed. In the women of Paris the average age at the menarche is 14 years and 6 months, in the women of smaller French towns it is 14 years and 9 months, in French countrywomen it is 14 years and 10 months.

How far the mode of nutrition is concerned in the production of these results is not yet determined.

4. The time of the menarche appears to be influenced by inheritance to this extent, that the daughters of women who began to menstruate early begin themselves to menstruate at an early age, whereas in other families we observe that both mothers and daughters began to menstruate late. But this relation is by no means a constant one.

Ploss has collected observations made in various countries and towns regarding the age at which menstruation begins, and the mean results of these observations are given below.

The average age at which menstruation began was:

The collective results of the investigations of French authors regarding the average age at which menstruation first appears are given in the following table:

from these observations we obtain an average of 15 years.

from these observations we obtain an average of 16 years and 3 months.

from these observations we obtain an average of 12 years and 7 months.

In 6,550 cases collected by Krieger menstruation first appeared:

From these figures it appears that in the 6,550 cases under consideration, the age 15 was that at which the first appearance of menstruation was most frequently observed, namely in 1,240 instances, or 18.9 per cent. The age 14 comes next, with 1,193 instances, or 18.2 per cent. The case in this series in which menstruation appeared earliest, namely in the ninth year, was observed by Mayer, the girl being a blonde of average height, good family, and German descent; the case in which menstruation appeared latest, namely in the twenty-ninth year, was that of a woman living in Berlin, who was sickly and chlorotic up to the time of her marriage, and in whom menstruation did not appear until some years after that event.

As regards climatic influences, all the data at our disposal prove that the hotter the climate the earlier the menarche. According to Marc d’Espine the age at puberty varies in an almost geometrical ratio with the mean annual temperature.

The dependence of the menarche upon climatic influences is clearly shown by the statistical data collected from various regions of the world. We append the general compilation of Gebhard dealing with this question.

A. Europe.

For Europe the data furnished by Ploss are grouped by Gebhard in the following manner.

1. Northern Europe.

The average age at which menstruation first appears, according to the older statistics, is in Swedish Lapland 18, in Norway, 16.12. In Copenhagen it is 16.75, in St. Petersburg 14.5.

More recent statistics for Finland are furnished by Engström. Among 3,500 women of pure Finnish descent, he found that menstruation began:

Thus, in nearly half of all Finnish women, menstruation begins with the completion of the fourteenth and fifteenth years. The statistics include women of all classes of society.

At the Pirogoff Congress Grusdeff furnished particulars of the first onset of menstruation in Russia among 10,000 women. Menstruation began:

In women of German race living in Russia puberty was earliest, occurring at the average age of 15.16 years; in Finnish women it was latest, occurring at the average age of 16.17 years.

2. Middle Europe.

In Germany, according to the tables of Krieger and L. Mayer, who have recorded 11,500 cases in all, menstruation begins most commonly (in 18.931 per cent. of the cases) at the age of 15; the next most frequent age is 14 (18.213 per cent. of the cases).

For Berlin, in a number of cases collected from the lower classes of society, we find the average age for the first appearance of menstruation to be 16.18 years.

Notwithstanding the more northerly situation of Berlin, the average age at puberty is somewhat less than in Munich, situated 4½ degrees to the southward, for the reason that the retardation dependent upon altitude makes itself manifest in the latter town, which is situate about 500 metres (1,640 feet) higher above the sea level. Whereas in Berlin 18 per cent. of all cases begin to menstruate at the age of 14, and 19 per cent. at the age of 15, in Munich the two leading years are 15 with a percentage of 17½, and 16 with a percentage of 18¾.

In Great Britain, according to Krieger, the average age at which menstruation begins is 15 years, 1 month, and 5 days. For Manchester the age given is 15 years, 6 months, and 23 days. In France, according to the calculation of Brierre de Boismont, the most frequent age for the first onset of menstruation is 16. In Paris the average age is 14 years, 6 months, and 14 days. Bohemia, Upper and Lower Austria, and Moravia have an average age of 16 years and 2 to 3 months.

3. Southern Europe.

In Southern Europe the influence of the higher mean temperature manifests itself. The average age at which Spanish girls begin to menstruate is 12. In Northern and Middle Italy the most frequent age is 14; in Southern Italy, 13. In Lyons the average age at which menstruation begins is 14 years, 5 months, and 29 days; in Marseilles and Toulon it is 13 years and 10 months. For Hungary, Doktor gives the statistics of 9,600 cases. In 22⅓ per cent. menstruation began at the age of 15; in 20½ per cent. at the age of 16, and in 10 per cent. at the age of 17. The earliest age among these cases was 8 years; the latest, 33 years. (The latter must no doubt be regarded as pathological.)

B. Asia.

In Palestine puberty most commonly occurs at the age of 13; in Turkey even as early as 10. Rouvier calculated the average of 742 cases observed in Syria to be the age of 12. As regards Persian women, the data vary between the age of 14 for the northern part of the country and the age of 9 or 10 for the southern. According to Joubert’s data in 46.4 per cent. of the indigens of India, menstruation begins at the age of 12 or 13. Similar figures are given for Ceylon and for Siam. In Japan menstruation most frequently begins at the age of 14, sometimes as early as 13; mothers of 15 are by no means rarities in this country, but for menstruation to begin before the age of 12 is considered a very exceptional occurrence. According to a table dealing with 584 women of Tokio menstruation began:

The data available regarding China are so exceedingly variable that little importance can be attached to them.

C. Africa, Oceania, and America.

The average age at which menstruation begins in the negro women of Africa is from 10 to 13. In Algeria puberty occurs at 9 or 10 years. Among the Australian indigens, menstruation commonly begins as early as 8 years, and at the very latest at the age of 12 years. The data available concerning the indigens of the Oceanic Archipelago are extremely variable and inexact, but we cannot go far astray in stating the age of puberty among these to be from 10 to 13. In tropical South America girls begin to menstruate from the age of 9 to 14 years. The Indian women of North America begin to menstruate at the ages of 12, 13, 14, or even as late as 18 or 20. In the Arctic zone of North America and in Greenland the onset of menstruation is delayed till 17 and even till 23 years.

As regards the position in life and the upbringing years it has been shown by numerous observers that among the well-to-do classes, whose mode of living is luxurious, and whose social circumstances allow free play to the imagination, menstruation begins at an earlier age than among the working classes, whose life is one of want and privation. According to the statistical data of Mayer’s regarding 6,000 women, menstruation began:

From this table we learn that in nearly one-fourth of the girls of the upper classes puberty occurs at the age of 14, whilst in girls of the lower classes barely one-sixth begin to menstruate at this age. The average age at the first menstruation in girls belonging to the upper classes is seen to be 14.69 years, but in girls belonging to the lower classes, 16.00 years. According to other observers the average age at the first menstruation is:

Comparative observations on women living in towns and women living in the country show also that in the former, menstruation begins on the average at an earlier age. According to Brierre de Boismont, the average age at the first menstruation is:

Similarly it was found by Ravn that menstruation first occurred:

Mayer states that the average age at which the first menstruation occurs is:

In Italy, according to Calderini, in a thousand instances, menstruation begins at the age of 14 in 280, at the age of 15 in 219, at the age of 13 in 205, at the age of 12 in 116, at the age of 16 in 89, at the age of 17 in 55, at the age of 18 in 14, at the age of 11 in 7, at the age of 10 in 6, and at the age of 20 in 6 instances. In girls attending town schools, the first menstruation most commonly occurs in the months of June and August; but in girls attending country schools most commonly in the spring months.

A certain hereditary predisposition is so far determinant in the matter of the early or late onset of the first menstruation, that from a knowledge of the age at which menstruation began in the mother, we are able with great probability to predict the age at which it will begin in the daughter. Among fifty cases which I investigated with this point in view, I found forty-one in which the daughters of mothers who had begun to menstruate early began themselves to menstruate early, usually indeed in about the same year of life; or conversely that when the mother had begun to menstruate late, late onset of menstruation was usually to be observed in the daughter also. Tilt relates a case in which a woman began to menstruate at the age of fourteen, and her daughter and granddaughter both began to menstruate at the same age. Courty observed a mother who began to menstruate at the age of eleven, and whose eight daughters all began to menstruate at the same age.

Gynecologists agree in stating that girls of sanguine temperament and powerful constitution begin to menstruate earlier than weakly and phlegmatic individuals. Tilt describes a peculiar ovarian temperament, in which menstruation begins early; such women have as a rule striking nervous sensibilities, with a dark complexion and glistening, longing eyes, always surrounded by dark rings.

The opinion is general that in girls with black hair, dark eyes, thick skin, and dark complexion, menstruation begins earlier than in blondes with blue eyes and delicate white skin. Brierre de Boismont states in this connection that not fair hair only, but also chestnut-tinted locks, indicate a late onset of menstruation. L. Mayer found that:

According to the same author, the average age at which menstruation begins is:

As regards race, it is well known that in Jewesses menstruation begins at an early age. According to Joachim the age of puberty varies very greatly among the different races inhabiting Hungary. The first menstruation appears:

First Appearance of Menstruation.

The first appearance of menstruation is commonly preceded by various symptoms dependent on the increased flow of blood to the genital organs. Such symptoms are: Sacrache; dragging sensation in the loins; an indefinite feeling of pressure in the lower part of the belly, especially in the region of the uterus and the ovaries, which region is sometimes also tender on pressure; a slight feeling of weariness in the lower extremities; sudden flushings or pallors; alternating sensations of heat and chilliness, sometimes accompanied by actual though slight change of temperature. In many cases also there are disturbances in the intestinal evacuations and urinary secretion, in the process of cutaneous transpiration, and in the functional activity of the gastro-intestinal canal. A frequently observed symptom is an increased irritability of the entire nervous system, with an inclination to melancholy and indefinite amorous desires—symptoms which Tilt denotes by the term “ovarianismus,” Emmet by the term “erection,” Lecal by the term “phlogose amoureuse,” and the older writers by the term “molimina menstrualia.”

The nervous irritability manifests itself already before the appearance of the menstrual flow by headache and moodiness, weariness, nervous irritability, and low spirits; further, by slight changes in the facial aspect, dark rings round the eyes, spontaneous blushing, uneasy sensations, epigastric pain, loss of appetite, a sensation of pressure in the abdomen, palpitation, vertigo, dragging sensations passing from the loins to the thighs, feeling of weakness and numbness in the lower extremities—symptoms which often endure for several months and in such cases tend to lower the resisting powers of the organism.

Courty enumerates as prodromal symptoms which are observed in the majority of girls before the first appearance of menstruation: swelling and tenderness of the breasts, sensation of fulness and weight in the hypogastric region, moderate intestinal meteorism, sacrache, aqueo-mucous vaginal discharge, finally, an itching sensation in the genital organs. These manifestations may also assume a morbid character, taking the form of violent abdominal and lumbo-sacral pain, general fatigue and weakness, dyspepsia and diarrhœa, cephalalgia, various kinds of neuralgia, some degree of moral aberration. After the first menstruation, two or three months may elapse before the girl menstruates again, but after the lapse of a year the flow usually recurs at quite regular periods. Sometimes the early periods are very violent and recur very frequently, every twenty days, for instance.

The greatest increase in size and weight occurs in the female sex at the time of the menarche. Amongst the poorer classes the greatest development in size and strength occurs between the ages of 13 and 15 years, whereas in the upper classes of society, those who ultimately attain the same weight exhibit their greatest growth at the ages of 12, 13, and 14 years. According to Pagliani the greatest growth in the female sex always precedes puberty, so that for example a girl who begins to menstruate at the age of 12 will grow most rapidly in the year preceding this, whereas a girl who begins to menstruate at a more advanced age will not undergo her most rapid phase of growth so early as the age of 11. According to the observations of Bowditch, A. Hey, Lombroso, Pagliani, and Ploss, up to the age of 11 or 12 years the growth of girls exceeds that of boys, but whereas in girls growth ceases suddenly at the age of 14, in boys growth proceeds regularly up to the age of 16 years. At birth boys are on the average 1 cm. (⅖″) longer than girls; but during puberty the female sex catches up the male in height, or even surpasses it. According to Ploss, a girl of 16 or 17 years is as tall as a young man of 18 or 19 years.

The earlier development of the female as compared with the male at the time of puberty is a constant phenomenon, to be observed in all races, in every climate, and in all strata of society. According to the statistical data published by the authors just quoted, the age of greatest development in the respective sexes is:

Puberty occurs in the female on the average about two years earlier than in the male, and upon this difference the observed differences in growth also depend.

The menarche in the wider signification of the term includes the development which occurs at the time of puberty, and continues through a period of several months, and even years, before complete sexual maturity is attained; and includes also the time, which may be considerable, following the first appearance of the menses and before the regular rhythm of the menstrual function is established and the full development of the female genital organs is attained. This time, which forms a notable phase of the sexual life of woman, is characterized by great changes in the genital organs and in the vital processes connected therewith, by a strong tendency to suffer from a series of very various pathological changes and disorders of function in the principal organs, and a lessened general resisting power to disease—a change which finds its most definite expression in the well-established fact that in this period of life the mortality among females is much greater than among males of corresponding age. According to the statistical data of Quetelet and Smits, from the age of 14 to the age of 18 (the period of the menarche) there are 128 deaths of females for every 100 deaths of males; and even in the four succeeding years, from the age of 18 to the age of 22, the unfavorable conditions peculiar to sex are witnessed by 105 deaths of females to every 100 deaths of males.

Many authors draw a distinction between the age of puberty (from the Latin pubes, puberis), when the growth of the pubic hair occurs as an external sign of sexual development, and the age of nubility (from the Latin nubere), when the individual becomes fitted for marriage. The distinction is a partial one only, inasmuch as capacity for copulation is attained already at puberty. The law, however, maintains such a distinction, the Austrian Penal Code, for example, regarding intercourse with a female less than fourteen years old as rape, and the German Code likewise punishing carnal knowledge of a girl under fourteen.

The signs of puberty in girls were noticed and explained in very early times. From the anthropological studies of Ploss and Bartels we take the following data regarding this matter. In the Bible we read (Ezekiel, xvi, 7): “Thy breasts are fashioned and thine hair is grown, whereas thou wast naked and bare.” The early Indian physician, Susruta, refers only to the regular recurrence of menstruation as a sign of puberty. That a woman is menstruating may be known by the fact that her face is swollen and bright. In the Roman Empire Justinian ordained that all young women should be examined as to the growth or absence of the pubic hair in order to ascertain if they were ripe for marriage. The early Chinese physicians recorded that in every woman at the age of fourteen or fifteen years a monthly flow of blood from the genital organs began, the period of recurrence being thirty days. The physicians of the Talmud express themselves variously regarding puberty in women. In one place they advance as a sign of puberty the growth of the hair on the genital organs; in another they speak of the notable enlargement of the breasts, and mention as a sign of more complete sexual development that the nipples become elastic. Other Talmudists refer to the appearance of a dark brown coloration in the areola and to the enlargement of the mons Veneris as signs of puberty. Savage races regard the first appearance of the menstrual flow as the only certain sign of puberty, and among many such races this is the occasion of peculiar ceremonial rites. The attainment of puberty in savage tribes is often solemnized by the seclusion of the girls from the time of the first menstruation; they fast during the period of seclusion, which sometimes terminates in an elaborate ritual of purification.

For two reasons in particular, the period of the menarche is a time of storm and stress to women, first on account of the developmental processes in the genital organs, and secondly on account of the intellectual changes that occur at this period.

The local cause is to be found in the extensive transformation of the ovaries and the uterus, by means of which a peculiar and powerful stimulus, the menstrual stimulus, is elaborated, which has a reflex influence upon heart and brain, vascular and nervous systems, and secretory and nutritive processes. Since we know that in every premenstrual period by the growth of the follicles hyperæmia is excited in the ovary, by means of which the liquor folliculi is increased in amount, we can well understand that at the time of the menarche the ripening of the graafian follicles is accompanied by a considerable degree of hyperæmia of the ovaries and of the whole of the genital organs, now undergoing their fullest development, and we can easily see how this hyperæmia may result in manifold reflex disturbances. But in addition to these reflex disturbances, we have once more to take into consideration the as yet imperfectly known chemical processes which are associated with the ripening and development of the graafian follicles, and an abnormal course of which may give rise to a disordered constitution of the blood, manifesting itself as chlorosis or in other ways. In connection with the growth and ripening of the ova, extensive and novel demands are made on the organism, and these may well endanger metabolic processes which are not established on a very secure foundation.

The other cause is to be found in the intellectual processes which occur at this time in the youthfully receptive, highly sensitive organ of mind, the brain. The girl growing into womanhood, who with astonishment and stress has witnessed the visible changes in her body, the outward signs of puberty, as they gradually make their appearance, receives powerful psychical stimulation which cannot fail to exercise an influence upon the entire nervous system and its complex interlacements, alike in the sensory and in the motor sphere.

The degree to which these influences radiating from the genital organs make themselves manifest is chiefly dependent upon the resisting power of the nervous system as a whole, upon the temperament, the inherited constitution, and the mode of education of the young girl. In children belonging to families noted for sensibility and irritability, in dwellers in large cities who have attended high schools for girls and have at an early age lifted the veil that covers the sexual processes, the reflex disturbances of the menarche will be more manifold and will manifest themselves with greater intensity than in children brought up in country districts, whose sensibilities are chiefly physical and whose mind is less susceptible to the influence of external stimuli.

A further important consideration is the time at which the menarche occurs, and whether on the one hand it is at or near the average age, or whether on the other, as precocious menstruation, it is unusually early, anticipating the general bodily development, or again as retarded menstruation it is unduly delayed. In some cases of retarded menstruation, the external genital organs are thoroughly well developed, and it is menstruation only that remains in abeyance; but in other cases the external genitals are also backward in development, the pubes and mons Veneris being but sparsely supplied with hair, and the breasts remaining very small.

In addition to these abnormal temporal relations of the menarche, certain other irregularities at the commencement of menstruation are worthy of note. Thus, the first menstruation may be normal, but thereafter amenorrhœa may persist for several months, or if the flow occurs it may be exceedingly scanty, or very pale in color; on the other hand, menstruation may be very profuse, lasting many days.

The environment in which the young girl is placed during the period of her sexual development has a great influence on the processes of the sexual life and on the pathological disturbances that affect these processes.

In working-class families the immoderate physical strain often thrown upon girls, in many cases continuous movements of the upper extremities whilst the lower extremities and the pelvis are absolutely quiescent, or conversely, an excessive employment of the muscles of the lower extremities—these circumstances in conjunction with insufficient nutriment, night-work, association when at work with persons of the opposite sex, and the frequent premature sexual stimulation, will combine to have a most deleterious effect.

Amongst country-folk, indeed, the girl has the enjoyment of fresh air, and as a rule nutritive food, moreover, there are not so many occasions of nervous stimulation; puberty therefore arrives more slowly and gives rise to less disturbance; but the ignorance of the girls very frequently leads to an early experience of coition, the natural and unnatural consequences of which have then to be taken into account.

Amongst the better classes of townspeople such hygienic regulations and educational measures are in common employment that young girls during the years of development usually receive reasonable care and attention—but very frequently, intercourse with older girls, association with young men, visits to theatres, evening-parties, and balls, and the perusal of stimulating literature, form unfavorable features of urban life which exercise their inevitable effects in the sexual sphere. In some cases, fortunately sufficiently rare, the stimulation of the sexual impulse and the longing for its satisfaction are so intense, that a kind of demi-vierge is brought into being, a young woman who is concerned only to preserve the physical token of virginity, but whose thoughts and fancies are anything but maidenly. It is to be feared that in consequence of the excessive freedom in education and the emancipated independence of feminine youth, these “half-virgins” are increasing both in number and in intensity, a fact which cannot fail to increase also the number of sexual maladies and perversions.

Anatomical Changes in the Female Genital Organs in the Period of the Menarche.

The female reproductive organs, which in childhood were in a comparatively quiescent state, now become powerfully active, as is witnessed by the changes that occur in the external genitals.

The soft, hairless vulva of the child becomes enlarged at the time of the menarche by the deposit of fat, and its substance becomes tough and elastic. Some time before puberty, fine, pale hairs make their appearance here and there, but not until puberty does the hairy covering of the pubic region become more or less thick. The growth of the denser pubic hair begins with the appearance of hairs along the middle of the mons Veneris and at the margins of the labia majora. Early sexual development is commonly indicated by an early and thick growth of the pubic hair. In the virgin this hair is smoother and less curly than in the later course of the sexual life. In certain tribes of negroes it is the custom for the young unmarried girls to shave off the pubic hair, which is not allowed to grow freely until after marriage. In some of the tribes of South Sea Islanders it is customary at puberty to tattoo the external genitals and the surrounding skin.

In young virgins the rima urogenitalis or vulval cleft is closed by the accurate opposition of the labia majora; the labia minora or nymphæ are delicate in texture, rose-red in color, hairless, free from fat, and completely covered by the labia majora; whilst the clitoris is likewise concealed. The sebaceous glands of the labia minora secrete a smegma which collects especially around the glans clitoridis, and as it undergoes decomposition diffuses a peculiar odor, resembling that of old cheese. A wing-like elongation of the labia minora in young girls, with free secretion and a generally moist appearance, leads to a suspicion of the practice of masturbation. In the virgin the orifice of the vagina is covered by the hymen.

The entrance to the vagina in the virgin is rounded, the posterior border of the aperture being deeply concave, whilst the anterior border is often slightly convex backwards. Where this feature is strongly marked, the orifice has a semilunar shape. The posterior concave border projects forward in the form of a fold, continuous above with the posterior vaginal wall; this fold is the hymen.

The infantile uterus is so proportioned that its neck (collum vel cervix uteri) constitutes the larger part of the organ, as much indeed as two-thirds. Owing to the small size of the body (corpus uteri), the whole uterus is very flat, and its borders ascend in a direction almost parallel to each other, diverging somewhat abruptly into the Fallopian tubes, recalling in some degree the two-horned embryonic form of the organ (uterus bicornis). The plicæ palmatæ on the surface of the cervical canal, which make up the arbor vitæ uterina, are strongly developed; the median longitudinal ridge bifurcates, and its divisions can be traced on either side into the uterine orifice of the Fallopian tube (ostium uterinum tubæ). The lips of the vaginal portion of the cervix are comparatively speaking very large and terminate in sharp angles. The vaginal mucous membrane is everywhere beset with long papillæ. The development of the uterus shortly before puberty consists chiefly in the enlargement of the body of the uterus, and the growth of its walls in thickness.

At the time of puberty, according to Toldt, the body of the uterus in the virgin has already increased till its length is half that of the entire organ; and at the first appearance of menstruation the body and neck of the virgin uterus are nearly equal, with perhaps a slight preponderance in size of the cervix, and the walls of the uterus have become convex. In consequence of this change the organ becomes pear-shaped, and the uterine cavity (cavum uteri) assumes the form of a triangle with moderately incurved sides. The cervical canal becomes wider in the middle; the margin of the os uteri becomes smooth and rounded. The walls of the virgin vagina are marked with numerous dentate transverse ridges (rugæ), especially near the lower end and on the anterior walls, the columns of the vagina (columnæ rugarum), from which the transverse ridges run to either side at right angles, extend half way up the vagina, and are of a hard consistence.

The characteristic changes in the ovary at the time of the menarche originate in the changes undergone by the ovarian follicles. A large number of small separate follicles is to be found already in the ovary of the new-born infant. These structures, known as primitive follicles, are formed by detachment from the egg-tubes that grow down into the stroma from the superficial germinal epithelium; they are spheroidal vesicles, enveloped by a single layer of cubical cells, and their interior is entirely filled by the primitive ovum or egg-cell. This latter consists of very finely granulated protoplasm with spherical nucleus and distinct nucleolus, but no trace of an investing membrane can as yet be discerned. The further development of the ovarian follicles takes according to Toldt the following course: A rapid multiplication of the cubical cells that form the wall of the follicle occurs, so that the ovum is surrounded by two, three, or several layers of cubical or rounded cells, and the whole follicle gradually increases in size. At the same time the ovum assumes an eccentric position in the interior of the follicle. At or near the middle of the follicle a slit-shaped space now appears, filled with a clear colorless fluid. As this space gradually enlarges, the follicle[^[19]] becomes converted into a vesicle filled with fluid, the wall of which is composed of small cubical cells. Simultaneously with the growth of the follicle a lamination of the elements of the surrounding stroma takes place, so that a somewhat sharply defined capsule is formed. In this condition these glandular structures of the ovary are known as graafian follicles.[^[19]]

Before puberty, these graafian follicles are small vesicles of a diameter of one to two millimetres, containing the large unicellular ova. Each of these consists of an envelope, the zona pellucida (also known as the zona radiata, or striated membrane of the ovum); an external granular mass of protoplasm, the vitellus or yolk; a vesicular, spherical nucleus, the germinal vesicle; and a nucleolus, which if single is large and prominent, the macula germinativa or germinal spot. As early as the second year of infancy every imaginable intermediate stage between the primitive follicle and the fully-developed vesicular graafian follicle can be observed.

At the time of puberty certain larger follicles are always to be distinguished, which have moved inward toward the interior layers of the ovary, whereas the smaller follicles have a more peripheral situation; thus, according to Waldeyer, we observe at this time in a section of the ovary, proceeding from without inward, first the epithelium, next the fibrous tunic, next the zone of younger follicles, and finally the zone of older follicles. According to Henle and Waldeyer, at the commencement of puberty, there are in each ovary about 36,000 ova, giving a total for the two of 72,000.

Fig. [15].—Primitive follicles.

In the further course of development of the graafian follicles at this period, the most advanced now reapproach the surface of the ovary, so that a fully-matured follicle comes to occupy almost the entire thickness of the cortical substance, and may even give rise to a localized bulging of the surface of the organ. In such a mature follicle, which has attained nearly the size of a pea, we recognize an outermost connective-tissue investment (theca folliculi), consisting of condensed ovarian stroma, in which two layers are distinguished, sometimes called simply outer tunic and inner tunic, sometimes known by the names of tunica fibrosa (outer) and tunica propria (inner), respectively; within this is the cellular layer known as the membrana granulosa (or stratum granulosum), the portion of which, now greatly enlarged, immediately surrounding the ovum is known as the discus proligerus (or cumulus oöphorus); the interspace between the discus proligerus and the membrana granulosa is filled with a clear fluid, the liquor folliculi. In consequence of the continued increase in its fluid contents, the graafian follicle ultimately bursts along the most prominent portion of the superficial wall, and the ovum passes out through the rupture, finding its way under normal conditions into the Fallopian tube and through this into the uterus. The follicle itself then undergoes a regressive metamorphosis, forming the corpus luteum, the rent in the envelope of which, after the absorption of the yellowish semi-fluid contents, undergoes cicatrization. Contemporaneously with this development at puberty of the process of ovulation, menstruation also for the first time makes its appearance, recurring thenceforward at four-weekly intervals as the regular catamenial discharge.

We append the account given by Pfannenstiel regarding the ovarian follicles. He writes: “In correspondence with the especial function of the female reproductive gland, which is to bring to maturity and to evacuate only after the lapse of a considerable period and at successive intervals, the ova which it has contained from the very outset, we find that primitive follicles continue to exist in the ovary up to the very end of the period of sexual activity, though naturally in diminishing numbers; and the size and shape of these primitive follicles remain nearly identical throughout the various periods of life. As the follicle ripens, the epithelium grows, the cells becoming cubical with a rounded nucleus, and increasing in number by cell-division, so that several layers are formed. As soon as these layers are three or four in number, a space, at first slit-shaped, forms in the epithelium on the peripheral surface of the ovum; this space is filled with fluid, known as the liquor folliculi; the peripheral layer of cells, the membrana granulosa, is thus separated from the mass of epithelial cells immediately enveloping the ovum, the discus proligerus, which is situate in the side of the follicle adjacent to the hilum of the ovary. By the increase of the liquor folliculi the graafian follicle is formed, a vesicle the envelope of which is formed by the multilaminar membrana granulosa, whilst in the pole of the vesicle directed toward the hilum ovarii is the ovum imbedded in the mass of cells forming the discus proligerus, a mass which has the form of a truncated cone. The liquor folliculi is formed by the epithelium, the nuclei of which disappear by chromatolysis or by simple atrophy whilst the cell-bodies liquefy in consequence of albuminous, not fatty, degeneration (Schottländer). Within the epithelium of the follicle we find the faintly glistening epithelial vacuoles of Fleming, likewise cells which liquefy and assist in increasing the bulk of the liquor folliculi. This liquor is a thin, serous fluid, and contains albumin. * * * Every graafian follicle has a bilaminar investing membrane, which is formed by the ovarian stroma. * * * The ovum of the growing follicle increases in size very slowly indeed, attaining on the average, according to Nagel, a diameter of 165 to 170 µ, it retains its zona pellucida, the greater part of the protoplasm of the cell is transformed into deutoplasm (food-yolk, or yolk-granules), the nucleus assumes an eccentric position. Between the zona pellucida and the cell-body a narrow perivitelline space appears. The ovum is then full-grown, but not yet fully prepared for fertilization; for this, maturation is required, certain changes in the germinal vesicle, which occur after the bursting of the follicle. * * * As a rule each follicle contains a single ovum. But two and even three ova have beyond doubt been observed in one follicle.”

According to Waldeyer, the bursting of the follicle is not to be regarded as dependent upon a sudden rise of pressure in its interior, but as the result of a gradual ripening process. At the deepest pole of the follicle, which in the course of its development has now approached the surface of the ovary, an exuberant growth takes place in the internal layer (tunica propria) of the theca folliculi, with a profuse formation of new vessels. Here numerous “epithelioid” cells, the “lutein-cells,” make their appearance. In consequence of this proliferation of the lutein-cells, the contents of the follicle are gradually pressed toward the “stigma,” the superficial pole of the follicle, and the follicle itself is pushed toward the surface until it finally comes into contact with the germinal epithelium. Meanwhile the follicular epithelium undergoes fatty degeneration, alike in the membrana granulosa and in the discus proligerus. In consequence of the proliferation of the lutein-cells, on the one hand, and the fatty degeneration of the epithelium, on the other, the follicle opens at its weakest point, the stigma, and the ovum is extruded, with the liquor folliculi, and a number of cells belonging to the follicular epithelium. (To illustrate these changes we have borrowed Figs. 15, 16, and 17 from the monograph, by Pfannenstiel on Diseases of the Ovary, in J. Veits’ Handbook of Gynecology.)

The ovaries, which in the new-born female infant are flattened, ribbon-like bodies one-half to one centimeter (0.2 to 0.4″) in length, and in childhood are cylindrical, with a perfectly smooth surface, assume at the time of puberty a more or less flattened form. During the menarche they have an elongated oval shape, flattened from side to side, their average length being 2.5 to 5.0 centimetres (1 to 2″), width 1.5 to 3.0 centimetres (0.59 to 1.18″), thickness 0.6 to 1.4 centimetres (0.24 to 0.55″), weight 5 to 8 grammes (77 to 123 grains). After the repeated occurrence of ovulation, the surface of the ovary becomes more and more uneven, being thickly covered with fossæ or scar-like fissures.

The vagina during virgin girlhood is narrow, and its mucous surface is beset with numerous rugæ, which may be plainly felt as well as seen. The calibre of the vagina is proportionately less the younger the girl. The examining finger is gripped by the vaginal wall as by an india-rubber tube (Maschka). The vaginal portion of the cervix is felt in the form of a truncated cone, with a smooth surface, rather dense in consistence; the external os opens at the bottom of a small depression on its surface, in the form of a short oval, the long axis of which is transversely directed. Shortly before the menarche, Bartholin’s glands become noticeable on either side of the lower end of the vagina between the sphincter muscles.

The clitoris in many cases attains a very large size, and this is apt to lead to sexual malpractices. According to Hyrtl, in southern countries the clitoris is larger than in temperate and cold climates. In the women of Abyssinia and among the Mandingoes and the Ibboes, the size is portentous, and amongst the first-named, circumcision of females is a customary operation. It is said that female slaves belonging to these races are greatly esteemed by the ladies of the harem, and are eagerly sought for. In the anatomicopathological museum at Prague there is a preparation of the female genital organs with a clitoris as large as the penis of a full-grown man.
