Tubal Blockage (Unilateral/Bilateral)

Tubal Blockage is a common cause of female infertility in which one (unilateral) or both (bilateral) fallopian tubes are blocked, preventing the sperm from reaching the egg or the fertilized embryo from moving to the uterus. The fallopian tubes are vital for natural conception, as fertilization typically occurs within them.

In unilateral blockage, only one tube is affected, and pregnancy may still occur if the other tube is healthy. In contrast, bilateral blockage significantly reduces the chances of natural conception and often requires medical intervention. The condition can result from infections such as pelvic inflammatory disease (PID), prior abdominal or pelvic surgeries, Endometriosis, or genital tuberculosis, which is relatively common in certain regions.

Symptoms are often absent, making diagnosis challenging. Some women may experience pelvic pain, irregular cycles, or a history of infertility. Diagnostic methods include hysterosalpingography (HSG), ultrasound-based tests, and laparoscopy, which also allows direct visualization of the tubes.

Treatment depends on the severity and cause. Mild cases may be managed surgically to reopen the tubes, while severe or bilateral cases are often treated with assisted reproductive techniques like IVF, which bypass the tubes entirely. Early diagnosis improves fertility outcomes and helps guide appropriate treatment strategies.
