Vasectomy is a form of birth control performed on men. It is most often performed under local anesthesia in the clinic, and is a safe and quick procedure with low morbidity. During the procedure, the vas deferens (sperm tubes) are cut through a small incision the scrotum so that sperm is excluded from the ejaculate. Using the no scalpel technique, about 99.9% of men and their partners will have permanent success with this method. Recovery is quick and most men are back to normal activities within 2-3 days following the procedure. Men should continue to use a form of protection for 3 months after the procedure and until a sperm analysis shows no evidence of sperm in the ejaculate.
