Can normal pregnancy occur if the vas deferens is blocked?

Patient's question:

We have been married for two years and have not been able to conceive. Recently, we went for a check-up and found that the vas deferens is blocked. The hospital has recommended surgical treatment. I would like to ask, can normal pregnancy occur if the vas deferens is blocked?

Doctor's answer:

Hello, the treatment methods for varicocele generally include the following:
1. Antibiotics: In cases where the obstruction of the vas deferens is caused by reproductive tract infections, swelling of the ejaculatory duct usually does not require surgery. Antibiotics and physical therapy can control the inflammation, allowing the swelling to subside and the reproductive tract to recover its patency.
2. Vas deferens anastomosis: If the obstruction is in the vas deferens, the obstructed segment can be removed, and anastomosis of the ends of the vas deferens can be performed.
3. Internal urethral orifice incision or urethroplasty: These procedures are used to treat urethral stricture or atresia caused by urethral trauma.
4. Tumor resection: Tumors or cysts in the spermatic cord, seminal vesicles, or prostate can be surgically removed.
