In women, the number of diseases which prevent conception is much greater than in man. The ovary may undergo cystic degeneration or become the seat of a tumor; but affections of the uterus and vagina cause more sterility than ovarian affections. This results chiefly from catarrh and inflammation which destroy the spermatozoa before they can reach the egg during its descent. Disorders of menstruation have much less influence on fecundity. The womb sometimes remains in an infantile state, which may also cause sterility. Other diseases of the female sexual organs have a more general pathological character and hardly influence sexual intercourse.

A method of rendering women sterile without castration (removal of the ovaries) consists in interrupting the communication between the ovaries and the womb by dislocation of the Fallopian tubes: this avoids all the evil effects of castration.

Certain inflammations and displacements of the uterus and ovaries are often the origin of pains, indispositions and nervous disorders in women. Irregularity and pain in menstruation are a frequent cause of neuroticism.

The hymen is seldom so strongly developed as to offer a serious obstacle to coitus; but when this occurs it may be removed by a slight operation. Young women often suffer from vaginismus, or painful spasms occurring when an object, such as the finger or penis, is introduced into the vagina.

Hermaphrodism in man is always pathological, extremely rare, and when it exists nearly always incomplete. These cases are generally incomplete mixtures concerning principally the correlative characters. A double function only exists in legends. I have myself seen a celebrated hermaphrodite named Catherine Hohmann who had a well-formed testicle on the left side enclosed in a fold of skin which resembled the larger lip of the vulva, while the penis was very short and resembled a clitoris. This individual, who was baptized as a woman, was certainly male on one side; on the other hand, the feminine nature was more than problematical. Menstruation was alleged to have occurred but was not established with certainty, any more than an ovary or uterus.

Much more frequent are inverted correlative sexual characters, such as bearded women, men with breasts; also mental sexual inversions, of which we shall speak later.

VENEREAL DISEASES[5]

We cannot give here a complete description of the venereal diseases, which constitute a terrible evil for humanity, by bringing a great deal of misfortunes and decadence into family and social life. Let us first point out the common error which attributes to sexual excess the evil effects which are really due to venereal disease. Although it may be uncommon, one may be infected by these diseases after an innocent kiss, a cut finger, by sitting on a privy contaminated by a person suffering from venereal disease, by the use of contaminated linen, etc., etc. A pachydermatous Don Juan, on the contrary, may abandon himself to the wildest sexual excess without being infected, if he is prudent and has good luck. On the other hand, young men may be infected after having been with a prostitute only once in their lives, and thus ruin their whole existence.

There are three kinds of venereal disease, which we will describe in a few words. To these may be added certain parasites, such as crab-lice and the itch, which are easily communicated by sexual intercourse with infected persons, but also in other ways.

Gonorrhea or Clap.—This disease consists in a purulent inflammation of the urethra caused by a microbe called the gonococcus. When treated properly it may be cured in a few weeks, but very often the inflammation becomes chronic and attacks the neighboring organs. Chronic clap, or "morning-drop," may lead in the male to permanent stricture of the urethra, which in turn may produce retention of urine, catarrh of the bladder and disease of the kidneys, which may be fatal. One attack of gonorrhea in no way protects against a second infection, but rather predisposes to it, and when this disease becomes chronic exacerbations or relapses of the acute stage often occur without fresh infection.
