By Mayo Clinic staffVasectomy is a simple surgery that provides birth control for men. A vasectomy prevents you from getting your partner pregnant by cutting and sealing the tubes that carry sperm into your semen. The surgery is straightforward and has a low risk of problems. For most men, a vasectomy doesn't cause any noticeable side effects. Before getting a vasectomy, you need to be sure you don't want to father a child in the future. Surgery to reverse a vasectomy is complicated and doesn't always restore fertility.
