Abstract: Vasectomy is a safe， effective and simple male sterilization procedure and an important contraceptive option. Hematoma and wound infection are most common postoperative complications with an incidence of 1% and 2%， respectively. A small number of men experience chronic pain or discomfort in the scrotum or testicles after vasectomy but less than 1% need to be treated by surgery. Vasectomy failure occurs in 0~2% of patients. Antisperm antibodies develop in over 60% of men after vasectomy. No increased health risks including immune-related diseases， atherosclerotic heart disease or testicular/prostate cancer have been proved by large epidemiology studies except a short-term elevation of risk of genitourinary tract infection or inflammation.

Key words: Vasectomy, Complications, Safety
