Patient's question:
My husband has always been very healthy, but we have been trying to conceive without success. Later, we found out that he has a blocked vas deferens and has been undergoing treatment for some time, but there has been no improvement. I really want to know what factors or underlying causes are leading to this condition.Doctor's answer:
Alright, obstruction of the vas deferens can cause obstructive azoospermia, which is also clinically referred to as pseudo-azoospermia. Its clinical manifestations and characteristics are as follows: normal-sized testicles, absence of sperm, normal levels of follicle-stimulating hormone (FSH) and testosterone in the serum, and normal results from testicular biopsy pathology. However, to confirm the diagnosis, contrast imaging must be performed. Factors or causes leading to vas deferens obstruction include: urogenital system infections, congenital abnormalities, such as epididymal tumors, seminal vesicle tumors, and prostate tumors, which can cause obstruction of the vas deferens.
