Blocked fallopian tubes are one of the most common causes of female infertility. The fallopian tubes play a crucial role in natural conception—they are the site where the sperm meets the egg and fertilization occurs. When the tubes are blocked, this meeting cannot happen, making natural pregnancy difficult or impossible. What Does a “Blocked Tube” Mean? A common test used to assess tubal patency is HSG (Hysterosalpingography). However, it is important to understand that an HSG report showing blocked tubes does not always mean a permanent blockage. There are three possibilities: 1. True blockage: due to infection, endometriosis, or adhesions 2. Tubal spasm: temporary tightening of the tube during the test 3. Cornual block: blockage at the uterine end of the tube Therefore, HSG findings must always be interpreted in the clinical context. May 4, 2026 Learn more
