This information is for educational purposes and does not constitute medical advice. Treatment depends on the location, severity, and cause of the blockage. Always consult a reproductive specialist or gynecologist. How to Unblock Blocked Fallopian Tubes Blocked fallopian tubes (tubal factor infertility) prevent the egg from meeting sperm and block the embryo from reaching the uterus. In many cases, they can be treated, but the method depends on where the blockage is (proximal, near the uterus, or distal, near the ovary) and what caused it (scar tissue, infection, adhesions).
