In young virgins the rima urogenitalis or vulval cleft is closed by the accurate opposition of the labia majora; the labia minora or nymphæ are delicate in texture, rose-red in color, hairless, free from fat, and completely covered by the labia majora; whilst the clitoris is likewise concealed. The sebaceous glands of the labia minora secrete a smegma which collects especially around the glans clitoridis, and as it undergoes decomposition diffuses a peculiar odor, resembling that of old cheese. A wing-like elongation of the labia minora in young girls, with free secretion and a generally moist appearance, leads to a suspicion of the practice of masturbation. In the virgin the orifice of the vagina is covered by the hymen. [Illustration: FIG. 9.—Reproductive organs of a new-born, powerfully developed female infant in median sagittal section.

(From Toldt: Atlas of Human Anatomy.—Rebman Company, New York.) ] The entrance to the vagina in the virgin is rounded, the posterior border of the aperture being deeply concave, whilst the anterior border is often slightly convex backwards. Where this feature is strongly marked, the orifice has a semilunar shape. The posterior concave border projects forward in the form of a fold, continuous above with the posterior vaginal wall; this fold is the hymen.
