Patient's question:
What are the symptoms of male vas deferens blockage? What symptoms are associated with blocked vas deferens?Doctor's answer:
Symptoms of Vas Deferens Blockage - Part 1Congenital Obstruction of the Sperm Duct: Congenital absence or occlusion of the vas deferens, congenital atrophy of the epididymis, non-connection between the epididymis and testis, congenital absence of the seminal vesicle or absence of the ejaculatory duct.
Symptoms of Vas Deferens Blockage - Part 2
Infection of the Sperm Duct: This symptom of vas deferens blockage includes tuberculosis, gonorrhea, and filariasis. When tuberculosis bacteria invade the wall of the vas deferens, the wall thickens, the vas deferens becomes hard and thickened, and forms a beaded appearance. The lesion can spread along the vas deferens to the tail of the epididymis, then affect the entire epididymis and testis. Bacterial infections primarily damage the tail of the epididymis and rarely involve the head of the epididymis. The vas deferens is often affected as well. Filariasis infection of the vas deferens and epididymis can also cause obstruction and blockage. When the infection involves the prostate and seminal vesicle, the symptoms of vas deferens obstruction may appear.
