The physiological purpose of the pubic hair is to prevent irritation of the genital organs by the sweat that would otherwise run down upon them, and to protect the skin from direct friction during the act of copulation. The labia majora in women during the menacme are usually strongly developed, their outer surface is hairy; in parous women we almost invariably observe small or even large lacerations of the frænulum pudendi or fourchette, in front of the posterior commissure of the vulva. On the inner surface also of the labia majora, the general characters of which are those of mucous membrane rather than of skin, fine hairs are also to be found. In multiparæ, and even in women who have frequently had sexual intercourse, these inner surfaces of the labia majora are not usually any longer in mutual contact, so that the rima urogenitalis or vulval cleft gapes more or less. In well-nourished women who have led the “sheltered life,” the dense and fat-containing connective tissue of the labia majora (continuous with and similar to that of the mons Veneris) gives these structures a certain firmness and elasticity, and the labia minora or nymphæ do not project beyond them. But when the genital organs are not well preserved, projection of the nymphæ occurs. In women whose genital organs are beautifully formed, the nymphæ are of a soft, delicate consistency, and their mucous membrane is of a pink color; but when the reproductive organs have been subjected to excessive stimulation, the nymphæ are dry, hard, brown in color, and they project from the vulval cleft. In women of the Hottentot and Bosjesman races, the nymphæ attain, as is well known, an excessive length, forming the so-called “Hottentot-apron;” and in certain other indigenous races of Africa, the enormous size of these organs renders resection necessary. During this sexual epoch, in women with strong sexual passion and having frequent sexual intercourse, the clitoris is largely developed, and sometimes the dorsum of the organ protrudes from between the anterior extremities of the labia majora. The vaginal orifice gapes a little, so that the irregular carunculæ myrtiformes are visible. In parous women, the vaginal orifice is enlarged in such a manner that the wall of the vagina passes directly and without limitation into the wall of the vestibule, and the external orifice (meatus) of the urethra is situate immediately in front of the anterior vaginal column, and thus lies within the vaginal orifice.
