Reference may finally be made to those cases in which the sexual impulse has developed notwithstanding the absence, verified or probable, of any sexual glands at all. In such cases sexual desire and sexual gratification are sometimes even stronger than normal. Colman has reported a case in which neither ovaries nor uterus could be detected, and the vagina was too small for coitus, but pleasurable intercourse took place by the rectum and sexual desire was at times so strong as to amount almost to nymphomania. Clara Barrus has reported the case of a woman in whom there was congenital absence of uterus and ovaries, as proved subsequently by autopsy, but the sexual impulse was very strong and she had had illicit intercourse with a lover. She suffered from recurrent mania, and then masturbated shamelessly; when sane she was attractively feminine. Macnaughton-Jones describes the case of a woman of 32 with normal sexual feelings and fully developed breasts, clitoris, and labia, but no vagina or internal genitalia could be detected even under the most thorough examination. In a case of Bridgman's, again, the womb and ovaries were absent, and the vagina small, but coitus was not painful, and the voluptuous sensations were complete and sexual passion was strong. In a case of Cotterill's, the ovaries and uterus were of minute size and functionless, and the vagina was absent, but the sexual feelings were normal, and the clitoris preserved its usual sensibility. Mundé had recorded two similar cases, of which he presents photographs. In all these cases not only was the sexual impulse present in full degree, but the subjects were feminine in disposition and of normal womanly conformation; in most cases the external sexual organs were properly developed.[15]
