Why does endometriosis cause infertility?
Scar tissue (adhesions) may form around the tubes and ovaries, interfering with their normal function. The presence of endometriosis in the pelvis may cause chemical changes in the pelvic that adversely affect the eggs and aperm, and thereby interfere with fertilsation. The presence of large endometriotic cysts may interfere with ovulation. Painful intercourse may result in a reduced frequency of coitus and therefore sub-fertility.
