Patient's question:
I have been married to my wife for many years. Recently, a check-up revealed that my vas deferens is blocked. I have been treated for two months, but there has been no improvement. I would like to know what factors or causes can lead to a blocked vas deferens.Doctor's answer:
Hello, congenital anomalies such as undescended or poorly developed vas deferens that do not communicate with the epididymis are often accompanied by underdeveloped seminal vesicles, leading to low semen volume and azoospermia. Inflammatory strictures: Various pathogens cause inflammation of the vas deferens, forming scars that lead to lumen occlusion, with severe cases resulting in azoospermia. Tumors: Tumors originating from the vas deferens itself or adjacent organs, which compress the lumen, are also factors or causes of azoospermia. Trauma or surgical damage, such as hernia repair, can also cause lumen obstruction.
