 A pregnancy is tough enough, guys. So, men, don't you think it's time for us to step up? A vasectomy is a 20-minute office-based procedure, and the American Urologic Guidelines states that vasectomies should be performed under local anesthesia with or without oral sedation. It is a very rare situation where a vasectomy needs to be done under general anesthesia. After all, general anesthesia is expensive, and it comes with risk.
