organs, are the cases in which seduction by others is the cause of masturbation. Nurses sometimes touch, stroke, and stimulate the external genital organs of the children entrusted to their care—boys and girls alike—either to keep them quiet, or for the gratification of their own lustful feelings. In this way the child, who in the case of all agreeable sensations has a natural desire for their repetition, is gradually led to imitate the manipulations which have given rise to the voluptuous sensations, and is thus seduced to the practice of masturbation.
In the preceding passages I have spoken of all kinds of mechanical stimulation of the genital organs, and also of erections25 occurring in small children. I now pass on to consider ejaculation. Whereas during normal intercourse in the sexually mature man and woman a fluid secretion is expelled, nothing of the kind is possible in children, at least such is the general opinion. Frequently, indeed, as regards the male sex, the end of childhood, properly speaking, is supposed to be indicated by the first ejaculation of semen. Matters are, however, by no means so simple as this. We have seen that the testicular secretion, the most important constituent of the semen, consists, as Fürbringer26 has pointed out, almost entirely of spermatozoa. But how is it in the case of children? The spermatozoa may be first formed at very varying ages. According to the investigations of Mantegazza,27 they rarely make their appearance earlier than the eighteenth year of life. Fürbringer does not unconditionally accept this view; but he has himself, as he has personally informed me, examined boys at ages of fifteen to sixteen in whom the ejaculation was entirely devoid of spermatozoa. But, on the other hand, he has found spermatozoa in the semen of a boy aged only twelve or thirteen years. I have myself examined the emissions of boys in a considerable number of cases, and have repeatedly found that, even in the case of boys of sixteen, the ejaculated secretions contained no spermatozoa. The reports of other investigators also show that as regards this point very wide individual variations occur. Hofmann28 has contributed some data to this discussion. A case published by Klose, in which pregnancy is alleged to have resulted from intercourse with a boy aged nine years, is, indeed, regarded by Hofmann as probably apocryphal. But he had personal knowledge of a case in which a woman was impregnated by a boy fourteen years of age. He assumes that when a boy's general development is advanced (masculine habit of body, large penis, &c.), his reproductive capacity will also make its appearance at an earlier age. But he has met with exceptions to this generalisation. Thus, in the post-mortem examination of the body of a boy aged fourteen, whose physique was still quite infantile, he found well-developed spermatozoa both in the testicles and in the seminal vesicles. In the case of two boys aged fifteen years, in whom the genital organs were powerfully developed, he found in one abundant spermatozoa, but in the other none at all. In two other boys, also fifteen years of age, in whom the pubic hair had not yet appeared, spermatozoa were present. They were absent, again, in a young man of eighteen years. Similar variations were found by Haberda. Thus, for example, in two boys aged fifteen and seventeen years, respectively, he found no spermatozoa, notwithstanding the fact that in both the pubic hair had grown. On the other hand, in a boy aged 13¾ years, with an abundance of pubic hair, numerous well-developed spermatozoa were present. Haberda is of opinion that, speaking generally, the first formation of the spermatozoa is associated with the appearance of the other indications of puberty. The earliest authenticated age at which spermotozoa have been known to appear is 13½ years; they have been found at this age by two separate investigators, one in Paris, the other in Berlin. Notwithstanding the fact that, as we have seen, such extensive variations occur, we are justified in making the general statement that in the case of children in our own country no spermatozoa are developed; if exceptions ever occur, they can relate only to the last year or year and a half of the second period of childhood.
We must now proceed to ask whether it is possible for ejaculation to occur in children at a time of life when the formation of spermatozoa in the testicles has not yet begun; this question must be answered with an unconditional affirmative. We have seen that the secretions of several other glands intermingle with the secretion of the testicles. These glands are the following: the prostate gland, the glands of the vesiculæ seminales and the vasa deferentia, the glands of Cowper, and the glands of Littré. It is certain that these glands begin to secrete at different times, and, above all, that some of them begin to secrete before spermatozoa have appeared in the testicles. Hence it is rightly believed that the capacity for coitus (potentia coeundi) develops much earlier than the capacity for procreation (potentia generandi)—a fact which was well known to Zacchias.29 Quae enim hanc juventutem vel præcedunt ætates, vel sequuntur aut plane semen non effundunt aut certe infoecundum aut male foecundum effundunt. Strassmann30 considers that in our climate the capacity for procreation begins at the earliest at the end of the fifteenth year, and the capacity for coitus at the end of the thirteenth year. In a number of cases in which in children I found stains on the underclothing, or in some other way obtained specimens of the ejaculated fluid, the results of the examination for spermatozoa were entirely negative. In a case which came under my notice a long time ago, that of a child seven years of age, I had assumed that the fluid with which the underclothing was stained was produced by inflammatory irritation of the urethra consequent upon masturbation. Subsequent experience, however, in conjunction with the observations of other investigators, has led me to the firm conviction that even in our climate we do not need to invoke the idea of such inflammatory irritation of the urethra in order to account for the ejaculation of fluid by children—at any rate when these are approaching the end of the second period of childhood. In the case of twelve-year-old boys, I believe that such ejaculations of fluid occur in quite a large number of cases. One instance, which did not come under my own observation, but was communicated to me by one of our best-known educationalists, relates to a boy only ten years of age. This boy, endeavouring to climb over a fence, repeatedly slipped back; while thus engaged, he experienced his first seminal emission. In this way he then masturbated several times.31
Let us now consider whence the ejaculated fluid can be derived prior to the age at which it comes to contain spermatozoa. In the first place, it is possible that the testicles themselves, before they begin to form the spermatozoa, may yet furnish an indifferent secretion, although in the adult the secretion of the testicles consists chiefly of the spermatozoa. We have also to consider the glands previously enumerated, whose secretions normally form constituents of the semen. We possess, however, hardly any trustworthy information regarding the time at which the glands of the vasa deferentia begin to secrete. The glands of Cowper, as Henle32 showed many years ago, begin to secrete within a few weeks after birth. He believed that these glands secreted continuously, but that the secretion was retained for a time in the ducts, and was discharged intermittently with the urine. For this reason he believed that the glands of Cowper did not form a part of the reproductive system. Subsequent investigations, however, have led us to believe that the secretion of Cowper's glands is one of the constituents of the semen. Another constituent is the secretion of the glands of Littré, and these glands also perhaps begin to secrete at a much earlier age than the testicles. We may regard it as certain that the seminal vesicles may contain secretion before any spermatozoa are formed in the testicles. As regards the prostate gland, it is supposed that this first begins to secrete at the commencement of the age of puberal development or even later. According to the data collected by Frisch, the prostate gland, comparatively small in childhood, first begins to grow quickly at the epoch of the puberal development. During childhood, the gland tissue is comparatively scanty, although it already contains concretions. Only during the puberal development does the prostate gland attain its full size; according to the researches of Englisch, who observed 1282 instances, this does not occur until after the full development of the testicles. Beyond question we are justified, from the information at our disposal, in concluding that the prostate gland begins to secrete comparatively late. But, on the other hand, it is equally clear that certain glands whose secretion in the adult forms part of the semen, begin to secrete long before any spermatozoa have been formed in the testicles, and may in this way give rise to the formation of a semen incapable of fertilising the ovum.
In respect of the extrusion of the fluid, we have to recognise two different ways in which this is effected: first, ejaculation, due to a rhythmical expulsive movement; and secondly, the urethrorrhoea ex libidine met with in adults, of which an account was given in the second chapter (p. 22). In my own investigations on the subject, I have been able to learn nothing regarding the occurrence in children of any urethrorrhoea ex libidine;
