Vasectomy is a safe and effective procedure for permanent contraception. Vasectomy is 30 times less likely to fail and 20 times less likely to have postoperative complications than its gynecologic counterpart. Complications from vasectomy are rare and minor in nature. Immediate risks include infection, hematoma, and pain. Complications seldom lead to hospitalization or aggressive medical management. Technique is surgeon dependent; however, certain techniques, such as fascial interposition, seem to decrease rates of vasectomy failure. Despite myriad vasectomy techniques, failure rates are less than those seen with tubal ligation. Available data suggest that vasectomized men do not seem at increased risk for immune-complex diseases.
