Does vas deferens blockage cause male infertility?

Patient's question:

Doctor, my colleague hasn't been happy these days. I asked her what was wrong, and she said her husband has a blocked vas deferens, so they haven't had children. It's not that he doesn't want them. Will a blocked vas deferens cause male infertility?

Doctor's answer:

Males who often cross their legs can cause varicose veins in their legs. When crossing legs, the compressed knee is subject to pressure, which can easily disrupt lower limb blood circulation. Maintaining the same position for a long time can lead to numbness in the legs, and if blood circulation is further obstructed, it may likely result in varicose veins or blood clots in the legs. This interferes with male perinatal health. Infertility can be stabilized, but the treatment period is generally long, and there is a high risk of recurrence after treatment. Therefore, medication must be used symptomatically during treatment. Additionally, it is recommended to adopt healthy lifestyle habits and maintain a proper diet during the treatment period.
