Mrs. H., twenty-four years of age, four years married, was confined by the author a year ago of a healthy girl. The patient complains of never having experienced any libido. Before her confinement coition caused her great pain and misery. Since her confinement she suffers no more pain during the act, but libido is still absent. She complains of great dryness of the parts, so that vaseline has to be used to facilitate walking. At the examination there was found redness of the vulva, catarrh and erosion of the cervix and anteflexio. In the following case of anaesthesia the author could discover no other cause but general weakness. Mrs. W., twenty-six years of age, was always pale and weak. Menstruation set in at twelve years of age. At nineteen she was married, and ten months later gave birth to her first child. Four years later gave birth to another child. For the last year she complains of stomach trouble and weakness, pain in the back and abdomen. Menstruation is now four to six days ahead of time and lasts five days. She never experienced orgasm but twice. Both times the intercourse was followed by pregnancy. Other times coition only excites her but never brings full satisfaction. The following day she suffers from severe headaches. An examination only revealed a catarrh of the cervix. The patient received a tonic, and the husband was given some hygienic rules to observe in initu. Five weeks later the husband informed the author that the anaesthesia had disappeared. Sometimes sexual anaesthesia is the result of a hard confinement producing lesion of the muscle bulbo-cavernosus or of the erectile tissue of the bulbs themselves. The blood is then prevented from leaving the bulbs and from entering the corpora cavernosa of the clitoris. In this way the erection of the clitoris, which is more or less necessary for the full and normal inducement of the orgasm, is rendered impossible. The author recently treated a young lady, twenty years of age. She had her first menstruation when she was sixteen years old and was always regular. She had been married eighteen months, and her baby was eight months old. The patient called to be treated for leucorrhoea, but her husband called the following day and stated that his wife has no pleasurable feeling during initus since her confinement. Before this event, she found perfect gratification. An examination revealed nothing but a catarrh of the cervix and a slight enlargement of the left ovary. Roubaud also relates the confidences of a patient who wished se stuprare manu a few days after her confinement, but could not, with all her manipulations, induce the desired orgasm. The normal potency returned only after a long rest.
