Making love during menstruation causes endometriosis

Lie. Endometriosis means the presence of endometrium (lining of the uterus which is eliminated in menstrual flow) in other organs such as the ovaries and fallopian tubes, and can even reach the intestine, bladder or vagina. It is true that sexual intercourse during menstruation causes part of the return flow to the uterus. This, however, does not cause endometriosis the overwhelming majority of women. Only 10% of women of childbearing age suffer from this health problem.
