The contribution of tubal and peritoneal factors in infertility is around 35% . Free and open fallopian tubes are necessary for gamete transport and fertilization to occur. Blocked tubes (including surgical tubal ligation), adhesions, and scar tissue are commonly associated with infertility. Endometriosis, appendicitis (especially when ruptured), abdominal or pelvic operations, infectious or non-infectious pelvic inflammatory diseases are among the main common causes in peritoneal factors.
