In the lady whose case has been mentioned, the act of coition produced a discharge of blood from the vulva. We have seen cases of a similar character, where the neck of the uterus presented no evidence of organic alteration to the touch. Females in whom this occurs should, however, be very careful in their pleasures, as this slight accident indicates a bad state of the system, and one which should be mistrusted. Sometimes, blood appears on return of coition, when females have not indulged for a long time. Rondelon cites an instance of this. It occurred in a lady from whom her husband had been absent for three years: at the end of this period, he returned. The frequency of coition the first night caused excessive uterine hemorrhage. A similar accident may result from this act, and a fortiori from its abuse, during or just before the menstrual period. Very serious hemorrhages have often occurred in consequence of excessive copulations. Tissot states--In 1746, a girl, twenty-three years old, submitted to the embraces of six Spanish dragoons, at a house near the gates of Montpelier. She died the next day, from excessive hemorrhage of the uterus. A similar case has been related by Virey. We know (said he) that a public woman, who submitted in one night to twenty-one soldiers, the next day died, with hemorrhage of the uterus. This was a dark, thin woman, in the flower of her age. (_Dict. des Sc. Med._, vol. xiv., p. 339.) Onanism causes in young women, and even in children, a discharge of blood from the vulva. This fact was mentioned by Duges. The blood lost is then never abundant, and the occurrence is by no means serious.
