Patient's question:
Here is the English translation of the provided text, with the newline characters kept as they are:"I have been trying to conceive with my wife for a while, but she hasn't gotten pregnant. Yesterday, we went to the hospital for a thorough check-up. The doctor said that my wife is normal, but it's my problem—my vas deferens is blocked. I need to pay more attention to it in daily life. What kind of help do you need: What causes the blockage of the vas deferens?"
Doctor's answer:
The causes of vas deferens blockage include: congenital abnormalities, where the vas deferens fails to develop normally or is underdeveloped, often associated with the development of the seminal vesicle leading to reduced semen volume and azoospermia; inflammatory stenosis, where various pathogens cause inflammation of the vas deferens, resulting in scar formation and impaired lumen patency, severe cases leading to azoospermia; tumors, originating from the vas deferens itself or adjacent organs, causing obstruction of the lumen due to tumor control; and trauma or surgical injury.During treatment, it is recommended to take protein zinc selenium chewable tablets or Jinghuo Su, which can comprehensively enhance sperm quality, the number of normally shaped sperm, motility, semen volume, semen liquefaction, and other sperm parameters, thereby increasing the chances of conception. Additionally, it is advisable to quit smoking and drinking, avoid spicy and irritating foods, and maintain a balanced diet for nutritional health.
