Does vas deferens blockage lead to male infertility?

Patient's question:

Hello doctor, my colleague has been unhappy these days. I asked her what was wrong, and she said her husband has a blocked vas deferens, so they haven't had children for a long time. It's not that he doesn't want to, but I was wondering if a blocked vas deferens can cause male infertility.

Doctor's answer:

1. Patients with a history of infertility may experience reduced or incomplete sexual climax, painful or weak ejaculation.
2. There may be a history of reproductive system infections, surgeries, or injuries.
3. Physical examination may reveal nodules in the vas deferens or epididymis, thickening, beaded changes, or absence.
Advice: It is recommended to undergo a comprehensive examination at a regular hospital to identify the cause and receive targeted treatment. During treatment, it is advised to take Jinghuo Su to comprehensively improve sperm quality, the number of normal-shaped sperm, motility, semen volume, semen liquefaction, and other sperm indicators, thereby increasing the success rate of pregnancy. Additionally, it is recommended to quit smoking and drinking, avoid spicy and irritating foods, and maintain a balanced diet.
