The majority of men have no significant effects on the body after vasectomy, but a very small number of patients may experience local discomfort, which may have certain effects on the body, including: 1. epididymal stagnation, after vasectomy, semen will accumulate in the epididymis and cannot be discharged, so there is swelling of the epididymis, and the symptoms of scrotal swelling or local pain will always appear. Some patients cannot tolerate it and need to undergo vasectomy again to restore the patency of the normal vas deferens to reduce the stagnation of the epididymis. 2. Chronic scrotal pain, after the vas deferens is rich in nerves for ligation surgery, some patients may have localized nerve fibroids that cause persistent pain, which is often unbearable and the conservative treatment of pain is not effective. 3. The majority of patients can restore normal reproductive function after vasectomy, but very few patients may have anti-sperm antibodies, and even after vasectomy, they still cannot achieve normal semen and restore reproductive function.
