Data regarding previous pelvic inflammation, abdominal surgery, endometriosis, obstetrical anamnesis, usage of IUD, occurrence of abdominal pain, vaginal discharge and metrorrhagia were obtained from 120 women with tubal infertility and compared to similar data from 126 pregnant women. Previous abdominal surgery, especially pelvic surgery was the most frequent risk factor present in 59% of the infertile women followed by pelvic inflammation (42%) and endometriosis (10%). In 23% of the infertile women there was no history of abdominal surgery, inflammation or endometriosis. Abdominal surgery, inflammation, ectopic pregnancy, salpingectomy and ovarian resection were significantly more frequent among the women with tubal infertility than among the pregnant women.
