In the Priapeia is an inscription which has thus been translated:-
"You see this organ, after which I"m called And which is my certificate, is humid; This moisture is not dew nor drops of rain, It is the outcome of sweet memory, Recalling thoughts of a complacent maid."
The translator supposes that s.e.m.e.n is referred to, but without doubt the allusion is to the theologians" distillatio.

A woman of 30, normal and intelligent, after conversing on love and pa.s.sion, and then listening to the music of Grieg and Schumann, felt real and strong s.e.xual excitement, increased by memories recalled by the presence of a sympathetic person. When then tested by the dynamometer the average of ten efforts with the right hand was found to be 28.2 (her normal average being 31.1) and with the left hand 28.0 (the normal being 30.0). There was, however, great variability in the individual pressures which sometimes equaled and even exceeded the subject"s normal efforts. The voluntary muscles are thus in harmony with the approaching general s.e.xual avalanche.

With regard to the relationship of detumescence to the blood-pressure Haig remarks: "I think that as the s.e.xual act produces low and falling blood-pressure, it will of necessity relieve conditions which are due to high and rising blood-pressure, such, for instance, as mental depression and bad temper; and, unless my observation deceives me, we have here a connection between conditions of high blood-pressure, with mental and bodily depression, and the act of masturbation, for this act will relieve those conditions, and will tend to be practiced for this purpose."

A medical correspondent speaks of subjective feelings of temperature coming over the body from 20 to 24 hours after congress, and marked by sensations of cooling of body and glow of cheeks. In another case, though la.s.situde appears on the second day after congress, the first day after is marked by a notable increase in mental and physical activity.

The germ cell never comes into the sphere of consciousness and cannot therefore concern us in the psychological study of the phenomena of the s.e.xual instinct. But it is otherwise with the sperm cell, and the seminal fluid has a relationship, both direct and indirect, to psychic phenomena which it is now necessary to discuss.
While the spermatozoa are formed in the glandular tissue of the testes, the seminal fluid as finally emitted in detumescence is not a purely testicular product, but is formed by mixture with the fluids poured out at or before detumescence by various glands which open into the urethra, and notably the prostate.[129] This is a purely s.e.xual gland, which in animals only becomes large and active during the breeding season, and may even be hardly distinguishable at other times; moreover, if the testes are removed in infancy, the prostate remains rudimentary, so that during recent years removal of the testes has been widely advocated and practiced for that hypertrophy of the prostate which is sometimes a distressing ailment of old age. It is the prostatic fluid, according to Furbringer, which imparts its characteristic odor to s.e.m.e.n. It appears, however, to be the main function of the prostatic fluid to arouse and maintain the motility of the spermatozoa; before meeting the prostatic fluid the spermatozoa are motionless; that fluid seems to furnish a thinner medium in which they for the first time gain their full vitality.[130]
When at length the s.e.m.e.n is e.j.a.c.u.l.a.t.ed, it contains various substances which may be separated from it,[131] and possesses various qualities, some of which have only lately been investigated, while others have evidently been known to mankind from a very early period. "When held for some time in the mouth," remarked John Hunter, "it produces a warmth similar to spices, which lasts some time."[132] Possibly this fact first suggested that s.e.m.e.n might, when ingested, possess valuable stimulant qualities, a discovery which has been made by various savages, notably by the Australian aborigines, who, in many parts of Australia, administer a potion of s.e.m.e.n to dying or feeble members of the tribe.[133] It is perhaps noteworthy that in Central Africa the testes of the goat are consumed as an aphrodisiac.[134] In eighteenth century Europe, Schurig, in his Spermatologia, still found it necessary to discuss at considerable length the possible medical properties of human s.e.m.e.n, giving many prescriptions which contained it.[135] The stimulation produced by the ingestion of s.e.m.e.n would appear to form in some cases a part of the attraction exerted by f.e.l.l.a.t.i.o; De Sade emphasized this point; and in a case recorded by Howard s.e.m.e.n appears to have acted as a stimulant for which the craving was as irresistible as is that for alcohol in dipsomania.[136]
It must be remembered that the early history of this subject is more or less inextricably commingled with folk-lore practices of magical origin, not necessarily founded on actual observation of the physiological effects of consuming the s.e.m.e.n or testes. Thus, according to W. H. Pea.r.s.e (Scalpel, December, 1897), it is the custom in Cornwall for country maids to eat the t.e.s.t.i.c.l.es of the young male lambs when they are castrated in the spring, the survival, probably, of a very ancient religious cult. (I have not myself been able to hear of this custom in Cornwall.) In Burchard"s Penitential (Cap. CLIV, Wa.s.serschleben, op. cit., p. 660) seven years" penance is a.s.signed to the woman who swallows her husband"s s.e.m.e.n to make him love her more. In the seventeenth century (as shown in William Salmon"s London Dispensatory, 1678) s.e.m.e.n was still considered to be good against witchcraft and also valuable as a love-philter, in which latter capacity its use still survives. (Bourke, Scatalogic Rites, pp. 343, 355.) In an earlier age (Picart, quoted by Crawley, The Mystic Rose, p. 109) the Manichaeans, it is said, sprinkled their eucharistic bread with human s.e.m.e.n, a custom followed by the Albigenses.
The belief, perhaps founded in experience, that s.e.m.e.n possesses medical and stimulant virtues was doubtless fortified by the ancient opinion that the spinal cord is the source of this fluid. This was not only held by the highest medical authorities in Greece, but also in India and Persia.
The s.e.m.e.n is thus a natural stimulant, a physiological aphrodisiac, the type of a cla.s.s of drugs which have been known and cultivated in all parts of the world from time immemorial. (Dufour has discussed the aphrodisiacs used in ancient Rome, Histoire de la Prost.i.tution, vol. II, ch. 21.) It would be vain to attempt to enumerate all the foods and medicaments to which has been ascribed an influence in heightening the s.e.xual impulse. (Thus, in the sixteenth century, aphrodisiacal virtues were attributed to an immense variety of foods by Liebault in his Thresor des Remedes Secrets pour les Maladies des Femmes, 1585, pp. 104, et seq.) A large number of them certainly have no such effect at all, but have obtained this credit either on some magical ground or from a mistaken a.s.sociation. Thus the potato, when first introduced from America, had the reputation of being a powerful aphrodisiac, and the Elizabethan dramatists contain many references to this supposed virtue. As we know, potatoes, even when taken in the largest doses, have not the slightest aphrodisiac effect, and the Irish peasantry, whose diet consists very largely of potatoes, are even regarded as possessing an unusually small measure of s.e.xual feeling. It is probable that the mistake arose from the fact that potatoes were originally a luxury, and luxuries frequently tend to be regarded as aphrodisiacs, since they are consumed under circ.u.mstances which tend to arouse the s.e.xual desires. It is possible also that, as has been plausibly suggested, the misunderstanding may have been due to sailors-the first to be familiar with the potato-who attributed to this particular element of their diet ash.o.r.e the generally stimulating qualities of their life in port. The eryngo (Eryngium maritimum), or sea holly, which also had an erotic reputation in Elizabethan times, may well have acquired it in the same way. Many other vegetables have a similar reputation, which they still retain. Thus onions are regarded as aphrodisiacal, and were so regarded by the Greeks, as we learn from Aristophanes. It is noteworthy that Marro, a reliable observer, has found that in Italy, both in prisons and asylums, lascivious people are fond of onions (La p.u.b.erta, p. 297), and it may perhaps be worth while to recall the observation of Serieux that in a woman in whom the s.e.xual instinct only awoke in middle age there was a horror of leeks. In some countries, and especially in Belgium, celery is popularly looked upon as a s.e.xual stimulant. Various condiments, again, have the same reputation, perhaps because they are hot and because s.e.xual desire is regarded, rightly enough, as a kind of heat. Fish-skate, for instance, and notably oysters and other sh.e.l.lfish-are very widely regarded as aphrodisiacs, and Kisch attributes this property to caviar. It is probable that all these and other foods which have obtained this reputation, in so far as they have any action whatever on the s.e.xual appet.i.te, only possess it by virtue of their generally nutritious and stimulating qualities, and not by the presence of any special principle having a selective action on the s.e.xual sphere. A beefsteak is probably as powerful a s.e.xual stimulant as any food; a nutritious food, however, which is at the same time easily digestible, and thus requiring less expenditure of energy for its absorption, may well exert a specially rapid and conspicuous stimulant effect. But it is not possible to draw a line, and, as Aquinas long since said, if we wish to maintain ourselves in a state of purity we shall fear even an immoderate use of bread and water.
More definitely aphrodisiacal effects are produced by drugs, and especially by drugs which in large doses are poisons. The aphrodisiac with the widest popular reputation is cantharides, but its s.e.xually exciting effects are merely an accidental result of its action in causing inflammation of the genito-urinary pa.s.sage, and it is both an uncertain and a dangerous result, except in skillful hands and when administered in small doses. Nux vomica (with its alkaloid strychnia), by virtue of its special action on the spinal cord, has a notably p.r.o.nounced effect in heightening the irritability of the spinal ejaculatory center, though it by no means necessarily exerts any strengthening influence. Alcohol exerts a s.e.xually exciting effect, but in a different manner; it produces little stimulation of the cord and, indeed, even paralyzes the lumbar s.e.xual center in large doses, but it has an influence on the peripheral nerve-endings and on the skin, and also on the cerebral centers, tending to arouse desire and to diminish inhibition. In this latter way, as Adler remarks, it may, in small doses, under some circ.u.mstances, be beneficial in men with an excessive nervousness or dread of coitus, and women, in whom o.r.g.a.s.m has been difficult to reach, have frequently found this facilitated by some previous indulgence in alcohol. The aphrodisiac effect of alcohol seems specially marked on women. But against the use of alcohol as an aphrodisiac it must be remembered that it is far from being a tonic to detumescence, at all events in men, and that there is much evidence tending to show that not only chronic alcoholism, but even procreation during intoxication is perilous to the offspring (see, e.g., Andriezen, Journal of Mental Science, January, 1905, and cf. W. C. Sullivan, "Alcoholism and Suicidal Impulses," ib., April, 1898, p. 268); it may be added that Bunge has found a very high proportion of cases of immoderate use of alcohol in the fathers of women unable to suckle their infants (G. von Bunge, Die Zunehmende Unfahigkeit der Frauen ihre Kinder zu Stillen, 1903) while even an approximation to the drunken state is far from being a desirable prelude to the creation of a new human being. It is obvious that those who wish, for any reason, to cultivate a strict chast.i.ty of thought and feeling would do well to avoid alcohol altogether, or only in its lightest forms and in moderation. The aphrodisiacal effects of wine have long been known; Ovid refers to them (e.g., Ars Am., Bk. III, 765). Clement of Alexandria, who was something of a man of science as well as a Christian moralist, points out the influence of wine in producing lasciviousness and s.e.xual precocity. (Paedagogus, Bk. II, Chapter II). Chaucer makes the Wife of Bath say in the Wife of Bath"s Prologue:-
"And, after wyn, on Venus moste [needs] I thinke: For al so siken as cold engendreth hayl, A likerous mouth moste have a likerous tayl, In womman vinolent is no defense, This knowen lechours by experience."
Alcohol, as Chaucer pointed out, comes to the aid of the man, who is unscrupulous in his efforts to overcome a woman, and this not merely by virtue of its aphrodisiacal effects, and the apparently special influence which it seems to exert on women, but also because it lulls the mental and emotional characteristics which are the guardians of personality. A correspondent who has questioned on this point a number of prost.i.tutes he has known, writes: "Their accounts of the first fall were nearly always the same. They got to know a "gentleman," and on one occasion they drank too much; before they quite realized what was happening they were no longer virgins." "In the mental areas, under the influence of alcohol," Schmiedeberg remarks (in his Elements of Pharmacology), "the finer degrees of observation, judgment, and reflection are the first to disappear, while the remaining mental functions remain in a normal condition. The soldier acts more boldly because he notices dangers less and reflects over them less; the orator does not allow himself to be influenced by any disturbing side-considerations as to his audience, hence he speaks more freely and spiritedly; self-consciousness is lost to a very great extent, and many are astounded at the ease with which they can express their thoughts, and at the acuteness of their judgment in matters which, when they are perfectly sober, with difficulty reach their minds; and then afterwards they are ashamed at their mistakes."
The action of opium in small doses is also to some extent aphrodisiacal; it slightly stimulates both the brain and the spinal cord, and has sensory effects on the skin like alcohol; these effects are favored by the state of agreeable dreaminess it produces. In the seventeenth century Venette (La Generation de l"Homme, Part II, Chapter V) strongly recommended small doses of opium, then little known, for this purpose; he had himself, he says, in illness experienced its joys, "a shadow of those of heaven." In India opium (as well as cannabis indica) has long been a not uncommon aphrodisiac; it is specially used to diminish local sensibility, delaying the o.r.g.a.s.m and thus prolonging the s.e.xual act. (W. D. Sutherland, "De Impotentia," Indian Medical Gazette, January, 1900). Its more direct and stimulating influence on the s.e.xual emotions seems indicated by the statement that prost.i.tutes are found standing outside the opium-smoking dens of Bombay, but not outside the neighboring liquor shops. (G. C. Lucas, Lancet, February 2, 1884.) Like alcohol, opium seems to have a marked aphrodisiacal effect on women. The case is recorded of a mentally deranged girl, with no nymphomania though she m.a.s.t.u.r.b.a.t.ed, who on taking small doses of opium at once showed signs of nymphomania, following men about, etc. (American Journal Obstetrics, May, 1901, p. 74.) It may well be believed that opium acts beneficially in men when the ejaculatory centers are weak but irritable; but its actions are too widespread over the organism to make it in any degree a valuable aphrodisiac. Various other drugs have more or less reputation as aphrodisiacs; thus bromide of gold, a nervous and glandular stimulant, is said to have as one of its effects a heightening of s.e.xual feeling. Yohimbin, an alkaloid derived from the West African Yohimbehe tree, has obtained considerable repute during recent years in the treatment of impotence; in some cases (see, e.g., Toff"s results, summarized in British Medical Journal, February 18, 1905) it has produced good results, apparently by increasing the blood supply to the s.e.xual organs, but has not been successful in all cases or in all hands. It must always be remembered that in cases of psychical impotence suggestion necessarily exerts a beneficial influence, and this may work through any drug or merely with the aid of bread pills. All exercise, often even walking, may be a s.e.xual stimulant, and it is scarcely necessary to add that powerful stimulation of the skin in the s.e.xual sphere, and more especially of the nates, is often a more effective aphrodisiac than any drug, whether the irritation is purely mechanical, as by flogging, or mechanico-chemical, as by urtication or the application of nettles. Among the Malays (with whom both men and women often use a variety of plants as aphrodisiacs, according to Vaughan Stevens) Breitenstein states (21 Jahre in India, Theil I, p. 228) that both ma.s.sage and gymnastics are used to increase s.e.xual powers. The local application of electricity is one of the most powerful of aphrodisiacs, and McMordie found on applying one pole to a uterine sound in the uterus and the other to the abdominal wall that in the majority of healthy women the o.r.g.a.s.m occurred.
Among anaphrodisiacs, or s.e.xual sedatives, bromide of pota.s.sium, by virtue of its antidotal relationship to strychnia, is one of the drugs whose action is most definite, though, while it dulls s.e.xual desire, it also dulls all the nervous and cerebral activities. Camphor has an ancient reputation as an anaphrodisiac, and its use in this respect was known to the Arabs (as may be seen by a reference to it in the Perfumed Garden), while, as Hyrtl mentions (loc. cit. ii, p. 94), rue (Ruta graveolens) was considered a s.e.xual sedative by the monks of old, who on this account a.s.siduously cultivated it in their cloister gardens to make vinum rutae. Recently heroin in large doses (see, e.g., Becker, Berliner Klinische Wochenschrift, November 23, 1903) has been found to have a useful effect in this direction. It may be doubted, however, whether there is any satisfactory and reliable anaphrodisiac. Charcot, indeed, it is said, used to declare that the only anaphrodisiac in which he had any confidence was that used by the uncle of Helose in the case of Abelard. "Cela (he would add with a grim smile) tranche la difficulte."
If s.e.m.e.n is a stimulant when ingested, it is easy to suppose that it may exert a similar action on the woman who receives it into the v.a.g.i.n.a in normal s.e.xual congress. It is by no means improbable that, as Mattei argued in 1878, this is actually the case. It is known that the v.a.g.i.n.a possesses considerable absorptive power. Thus Coen and Levi, among others, have shown that if a tampon soaked in a solution of iodine is introduced into the v.a.g.i.n.a, iodine will be found in the urine within an hour. And the same is true of various other substances.[137] If the v.a.g.i.n.a absorbs drugs it probably absorbs s.e.m.e.n. Toff, of Braila (Roumania), who attaches much importance to such absorption, considers that it must be a.n.a.logous to the ingestion of organic extractives. It is due to this influence, he believes, that weak and anaemic girls so often become full-blooded and robust after marriage, and lose their nervous tendencies and shyness.[138]
It is, however, most certainly a mistake to suppose that the beneficial influence of coitus on women is exclusively, or even mainly, dependent upon the absorption of s.e.m.e.n. This is conclusively demonstrated by the fact that such beneficial influence is exerted, and in full measure, even when all precautions have been taken to avoid any contact with the s.e.m.e.n. In so far as coitus reservatus or interruptus may lead to haste or discomfort which prevents satisfactory o.r.g.a.s.m on the part of the woman, it is without doubt a cause of defective detumescence and incomplete satisfaction. But if o.r.g.a.s.m is complete the beneficial effects of coitus follow even if there has been no possibility of the absorption of s.e.m.e.n. Even after coitus interruptus, if it can be prolonged for a period long enough for the woman to attain full and complete satisfaction, she is enabled to experience what she may describe as a feeling of intoxication, lasting for several hours. It is in the action of the o.r.g.a.s.m itself, and the vascular, secretory, and metabolic activities set up by the psychic and nervous influence of coitus with a beloved person, that we must seek the chief key to the effects produced by coitus on women, however these effects may possibly be still further heightened by the actual absorption of s.e.m.e.n.[139]
The positive action of s.e.m.e.n, or rather of the testicular products, has been much investigated during recent years, and appears on the whole to be demonstrated. The notable discovery by Brown-Sequard, a quarter of a century ago, that the ingestion of the testicular juices in states of debility and senility acted as a beneficial stimulant and tonic, opened the way to a new field of therapeutics. Many investigators in various countries have found that testicular extracts, and more especially the spermin as studied by Poehl,[140] and by him regarded as a positive katalysator or accelerator of metabolic processes, exert a real influence in giving tone to the heart and other muscles, and in improving the metabolism of the tissues even when all influences of mental suggestion have been excluded.[141]
As the ovaries are strictly a.n.a.logous to the testes, it was surmised that ovarian extract might prove a drug equally valuable with testicular products. As a matter of fact, ovarian extract, in the form of ovarin, etc., would seem to have proved beneficial in various disorders, more especially in anaemia and in troubles due to the artificial menopause. In most conditions, however, in which it has been employed the results are doubtful or uncertain, and some authorities believe that the influence of suggestion plays a considerable part here.
There is, however, another use which is subserved by the testicular products, a use which may indeed be said to be implied in those uses to which reference has already been made, but is yet historically the latest to be realized and studied. It was not until 1869 that Brown-Sequard first suggested that an important secretion was elaborated by the ductless glands and received into the circulation, but that suggestion proved to be epoch-making. If these glandular secretions are so valuable when administered as drugs to other persons, must they not be of far greater value when naturally secreted and poured out into the circulation in the living body? It is now generally believed, on the basis of a large and various body of evidence, that this is undoubtedly so. In a very crude form, indeed, this belief is by no means modern. In opposition to the old writers who were inclined to regard the s.e.m.e.n as an excretion which it was beneficial to expel, there were other ancient authorities who argued that it was beneficial to retain it as being a vital fluid which, if reabsorbed, served to invigorate the body. The great physiologist, Haller, in the middle of the eighteenth century, came very near to the modern doctrine when he stated in his Elements of Physiology that the sperm acc.u.mulated in the seminical vesicles is pumped back into the blood, and thus produces the beard and the hair together with the other surprising changes of p.u.b.erty which are absent in the eunuch. The reabsorption of s.e.m.e.n can scarcely be said to be a part of the modern physiological doctrine, but it is at least now generally held that the testes secrete substances which pa.s.s into the circulation and are of immense importance in the development of the organism.
The experiments of Shattock and Seligmann indicate that the s.e.m.e.n and its reabsorption in the seminal vesicles, or the nervous reactions produced by its presence, can have no part in the formation of secondary s.e.xual characters. These investigators occluded the vas deferens in sheep by ligature, at an early age, rendering them later sterile though not impotent. The secondary s.e.xual characters appeared as in ordinary sheep. Spermatogenesis, these inquirers conclude, may be the initial factor, but the results must be attributed to the elaboration by the t.e.s.t.i.c.l.es of an internal secretion and its absorption into the general circulation.[142]
When animals are castrated there is enlargement of the ductless glands in the body, notably the thyroid and the suprarenal capsules.[143] It is evident, therefore, that the secretions of these ductless glands are in some degree compensatory to those of the testes. But this compensatory action is inadequate to produce any s.e.xual development in the absence of the testes.
We see, therefore, how extremely important is the function of the testis. Its significance is not alone for the race, it is not simply concerned with the formation of the spermatozoa which share equally with the ova the honor of making the mankind of the future. It also has a separate and distinct function which has reference to the individual. It elaborates those internal secretions which stimulate and maintain the physical and mental characters, const.i.tuting all that is most masculine in the male animal, all that makes the man in distinction from the eunuch. Among various primitive peoples, including those of the European race whence we ourselves spring, the most solemn form of oath was sworn by placing the hand on the testes, dimly recognized as the most sacred part of the body. A crude and pa.s.sing phase of civilization has ignorantly cast ignominy upon the s.e.xual organs; the more primitive belief is now justified by our advancing knowledge.
In these as in other respects the ovaries are precisely a.n.a.logous to the testes. They not only form the ova, but they elaborate for internal use a secretion which develops and maintains the special physical and mental qualities of womanhood, as the testicular secretion those of manhood. Moreover, as Cecca and Zappi found, removal of the ovaries has exactly the same effect on the abnormal development of the other ductless glands as has removal of the testes. It is of interest to point out that the internal secretion of the ovaries and its important functions seem to have been suggested before any other secretion than the sperm was attributed to the testes. Early in the nineteenth century Cabanis argued ("De l"Influence des s.e.xes sur le Caractere des Idees et des Affections Morales," Rapport du Physique et du Moral de l"Homme, 1824, vol. ii, p. 18) that the ovaries are secreting glands, forming a "particular humor" which is reabsorbed into the blood and imparts excitations which are felt by the whole system and all its organs.

The composite character of the s.e.m.e.n was recognized by various old authors, some of whom said, (e.g., Wharton) that it had three const.i.tuents, which they usually considered to be: (1) The n.o.blest and most essential part, from the t.e.s.t.i.c.l.es; (2) a watery element from the vesiculae; (3) an oily element from the prostate. Schurig, Spermatologia, 1720, p. 17.
