Tubal Disease
Tubal disease (tubal factor infertility or fallopian tube obstruction) is a type of female infertility that occurs when the fallopian tubes are blocked or damaged and prevents the egg and sperm from meeting. Tubal disease accounts for approximately 25-30% of all infertility diagnoses.
Endometriosis, abdominal or gynecological surgery (bowel surgery, cesarean section, ruptured appendix, etc.), or sexually transmitted infections (from chlamydia or gonorrhea) can cause fallopian scarring that can block the egg from entering or traveling down your fallopian tube to meet the sperm.
Tubal ligation (having your “tubes tied” to prevent pregnancy) can also leave your fallopian tubes damaged. However, reconstructive surgery to reverse tubal ligation is often successful.
