The fallopian tubes play an important role in transporting sperm, taking in eggs and transporting fertilized eggs to the uterine cavity. The main cause of tubal incompetence or dysfunction is acute and chronic tubal inflammation. Severe inflammation of the fallopian tubes can cause complete tubal incompetence, while some inflammatory diseases do not cause blockage of the tubal lumen, but the endometrium is damaged by the inflammation and affects the ciliary movement of the endometrial cells, and the scar formation makes the tubal wall stiff and affects the peristalsis of the fallopian tubes, thus affecting the meeting and transport of sperm and eggs and causing infertility. Tubal inflammation can also occur as a result of inflammation of the organs or tissues surrounding the fallopian tubes, especially when inflammatory adhesions form around the umbrella of the fallopian tubes or ovaries, preventing the umbrella of the fallopian tubes from sucking the discharged oocytes into the tubes to meet the sperm, such as septic appendicitis and tuberculous peritonitis. Patients who have suffered from adnexitis, septic appendicitis, tuberculous peritonitis, tuberculosis, endometriosis, incomplete abortion, post-abortion fever, abdominal pain and puerperal infection, sexually transmitted diseases such as gonorrhea, and patients with tubal malformations may have abnormal tubal function and suffer from tubal infertility.
