Patient's question:
The lower abdomen always, and I've been married for many years but haven't been able to get pregnant. The hospital check-up said it was due to blocked fallopian tubes. Please ask: What are the causes of blocked vas deferens?Doctor's answer:
Vas deferens obstruction is a common cause of male infertility, often considered to be triggered by difficulties in the transportation of sperm. Congenital intestinal obstruction or lack of smooth passage in the vas deferens, congenital atrophy of the epididymis, lack of connection between the epididymis and testes, or congenital absence of the seminal vesicles or vas efferens. If these issues exist, sperm cannot be expelled normally, and their ability to mature and gain motility is impaired. Any blockage in the remote attack passage can obstruct sperm expulsion, leading to infertility. It is reported that vas deferens obstruction accounts for about 7.4% of male infertility cases, while in cases of azoospermia, it can reach over 40%. Therefore, vas deferens obstruction is one of the common causes of male infertility.
