Menstruation in Man.--Periodic discharges of blood in man, constituting what is called "male menstruation," have been frequently noticed and are particularly interesting when the discharge is from the penis or urethra, furnishing a striking analogy to the female function of menstruation. The older authors quoted several such instances, and Mehliss says that in the ancient days certain writers remarked that catamenial lustration from the penis was inflicted on the Jews as a divine punishment. Bartholinus mentions a case in a youth; the Ephemerides several instances; Zacutus Lusitanus, Salmuth, Hngedorn, Fabricius Hildanus, Vesalius, Mead, and Acta Eruditorum all mention instances. Forel saw menstruation in a man. Gloninger tells of a man of thirty-six, who, since the age of seventeen years and five months, had had lunar manifestations of menstruation. Each attack was accompanied by pains in the back and hypogastric region, febrile disturbance, and a sanguineous discharge from the urethra, which resembled in color, consistency, etc., the menstrual flux. King relates that while attending a course of medical lectures at the University of Louisiana he formed the acquaintance of a young student who possessed the normal male generative organs, but in whom the simulated function of menstruation was periodically performed. The cause was inexplicable, and the unfortunate victim was the subject of deep chagrin, and was afflicted with melancholia. He had menstruated for three years in this manner: a fluid exuded from the sebaceous glands of the deep fossa behind the corona glandis; this fluid was of the same appearance as the menstrual flux. The quantity was from one to two ounces, and the discharge lasted from three to six days. At this time the student was twenty-two years of age, of a lymphatic temperament, not particularly lustful, and was never the victim of any venereal disease. The author gives no account of the after-life of this man, his whereabouts being, unfortunately, unknown or omitted.
