A vasectomy is a minor surgery to close off the vas deferens (the tubes that deliver sperm from the testes). Usually a vasectomy is performed as a means of contraception.
The procedure takes 15-30 minutes typically, causes little to no complications, and no change in sexual function. Over 500,000 vasectomies are performed in the United States each year and are very safe and effective. Vasectomy is less invasive than a tubal ligation (the female equivalent involving the uterus) and is easily reversed. Vasectomies have proven to be an effective way of maintaining permanent birth control.
