Varicocele surgery is relatively sophisticated and generally does not damage the vas deferens, and the probability of affecting the vas deferens is relatively small. Varicocele surgery includes open, laparoscopic or microscopic ligation of the high spermatic veins. The risks of the surgery are generally relatively small, and the operation of varicocele surgery only targets the spermatic veins, which basically does not cause damage to the vas deferens. However, any surgery carries certain risks. Complications of varicocele surgery include scrotal edema, testicular sheath effusion, testicular atrophy, nerve damage, acute epididymitis, etc., which also includes damage to the vas deferens. If you have varicocele surgery, it is recommended that you seek timely consultation in a regular hospital to choose the appropriate treatment measures.
