- Fallopian tube
- One of pair of tubes in the human female that carry the egg from the ovary to the uterus. Fertilization takes place here, but implantation normally occurs in the uterus. [View] Several sexually-transmitted diseases (STDs), especially gonorrhea and infections by chlamydia can cause scarring and blocking of the tubes and are a major cause of infertility. In tubal ligation, the fallopian tubes are surgically cut and their ends tied to prevent pregnancy.
