_Sterility_ of the sexes: no inconsiderable number of both sexes are incapacitated from exercising that important and divine function of giving creation to their own species. The _causes_ in the male sex are, palsy, or torpidity of the penis, or its nerves, or generative organs; the penis short, monstrous in size, its prepuce straitned; impediments in the urethra and seminal ducts; testicles, epididymidis, vasa deferentia; the semen inert, vapid, aqueous, scanty; weakness of the ejecting or accelerator muscles; corpulency; too tense erection; old age; castration, manustupration, too frequent coition, extreme chastity, venereal disease, inebriety, broken constitution, tabes-dorsalis. In the female sex, original structure of some part of the generative machinery of the ovarium, fallopian tubes, womb, vagina, labia, clitoris; straitness, concretion, obstruction of the vagina or womb from inflammation, scirrhus, polypus; cold frigid temperament; promiscuous coition; excess of venery, irritability; fluor albus, obstructed menses, irregular menstruation, cachexy.
_Morbid irritability of the genitals_, including priapism, pollution, furor uterinus. Of involuntary pollution we have treated under dorsal tabes. In our climate the uterine mania rarely occurs in that extreme of indecency described by authors. The woman at first is bashful and silent; the pulse and circulation are agitated on mentioning a venereal topick; by significant looks and gestures she betrays her passion; and if disappointed, becomes low-spirited, anxious, and wastes in flesh. The same has happened to some women who had the mortification to be linked with impotent husbands. Sometimes, however, this universal passion has burst into a flame; the woman losing all sense of shame, soliciting, with obscenity in speech and gestures, the embraces of the other sex; and raving on this theme with maniacal insanity. The _causes_, acrid serum, spasm, inflammation of the urethra, vagina, or other generative organs; irritation of the bladder, womb, rectum; obstructed menses; fluor albus, heat, excoriation of the vagina, venereal; stimulating, acrid, diureticks, and emmenagogues; stimulating diet and drink, excess of venery, manustupration, libidinous books, prints; protrusion of the vagina.
