Fallopian tube abnormalities are responsible for about 35% of infertility. Fallopian tube abnormalities include tubal scarring or blockage (most commonly from pelvic infections), prior abdominal surgeries, and endometriosis. The fallopian tubes are initially evaluated by a hysterosalpingogram (HSG) and can, if necessary, be more thoroughly evaluated with a laparoscopy. A laparoscopy may correct fallopian tube damage and improve fertility. If the fallopian tubes are severely damaged or surgery does not enable conception, in vitro fertilization (IVF) to bypass the tubes may be recommended. In cases of blocked and dilated fallopian tubes, patients may consider surgery to open or remove fallopian tubes before IVF to improve their chances of pregnancy.
