Sonini describes “as peculiar to women of Egyptian or Koptic descent, the presence of a thick, fleshy, but soft and pendent outgrowth in the pubic region, completely covered with hair,” which he compares to the hanging caruncle on the bill of the male turkey. This appendage becomes thicker and longer with advancing years. Sonini found such an appendage one-half inch in length in a girl of eight years, one of more than four inches in a woman of twenty to twenty-five years. Circumcision in girls consists in the removal of this outgrowth, which hinders copulation; in that part of the world the operation is usually effected in the seventh or eighth year, just before puberty.
The circumcision of girls as practiced by Mahommedan peoples in Africa is said by Ploss and Bartels to consist in abscission of the labia minora, the clitoris, and the præputium clitoridis. Brehm is of opinion that the object of the operation is to diminish the intensity of the sexual impulse, so overpowering among these races; but others believe that the great enlargement of the clitoris and the labia minora usual in those countries is regarded as a serious defect in beauty, a defect removed by the operation; whilst others again hold that the circumcision is required for the removal of the hindrance to copulation presented by the abnormally large clitoris. Closely related to the operation of circumcision in females, according to Ploss and Bartels, is the custom peculiar to Africa of infibulation, wherein, after a preliminary cutting operation like that for circumcision, the fresh wound surfaces are brought into accurate opposition, either by sutures or by appropriate bandages, so that when cicatrization occurs the vulval cleft is closed except for a very small aperture. The object of infibulation is to enforce on girls complete abstinence from sexual intercourse. (Before marriage, the vulval cleft is reopened to an extent corresponding with the size of the genital organs of the future husband; and when pregnancy occurs, the opening is still further enlarged before parturition; but after that event, the wound surfaces are refreshed, and the whole opening is once more closed). On the other hand, in many savage tribes, elongation of the labia minora and the clitoris is artificially undertaken from the earliest years of girlhood, this elongation being regarded as a beauty.
The parts of the external reproductive organs of the female concerned in sexual sensation, first described as such by Kobelt, are already fully developed at the time of the menarche. Of these parts a small portion only, the glans clitoridis, is visible externally, surrounded by the præputium clitoridis, a prolongation of the labia minora, which passes round the front of the clitoris, and sends from each side a fine process behind the glans to become attached to its under surface, forming the frænum of the clitoris. The erectile apparatus of the external genitals is formed by the corpora cavernosa clitoridis. As two delicately constructed trabecular masses of erectile tissue, the crura of the clitoris, these are attached on either side to the inferior or descending rami of the pubic bones; at first passing upwards parallel to the bones, they subsequently curve downward as they converge and unite to form the body of the clitoris; these masses of erectile tissue embrace the sides and the front of the lower extremity of the vagina. This erectile apparatus, when the supply of arterial blood is greatly accelerated and at the same time the outflow of venous blood is diminished, becomes distended with blood, enlarged and stiffened; the process of erection plays an important part, as we shall explain more fully later, in the production of sexual excitement and sexual pleasure during the act of copulation.
In the virgin and in the earlier phases of the sexual life, the hymen is so characteristic an organ that its more minute description would seem desirable.
The hymen, a fold of mucous membrane, springing from the periphery of the vaginal orifice, separates as a perforated diaphragm the vagina from the vulva. Between the two epithelial layers of which, as a fold of mucous membrane, the hymen consists, is a supporting layer of connective tissue of variable strength; in other respects the mucous membrane of the hymen has the same structure as the mucous membrane of the vagina. On its inner surface the rugæ and folds of the vaginal mucous membrane are prolonged. The shape of the hymen is very variable; most commonly its aperture is more or less central, so that the hymen has a ringed or semilunar shape.
