Vasectomy is a safe and effective birth control choice for men who are certain they don't want to father a child in the future. It is nearly 100% effective in preventing pregnancy. Having the procedure means you won't need to take birth control steps before sex.
A vasectomy prevents the supply of sperm to your semen. It's done by cutting and sealing the tubes carrying sperm. Vasectomy has a low risk of problems and side effects, and usually can be performed in an outpatient setting under local anesthesia.
Before getting a vasectomy, you need to be certain you don't want to father a child in the future. Although vasectomy reversals are possible, vasectomy should be considered a permanent form of male birth control.
Vasectomy offers no protection from sexually transmitted infections. A condom still is necessary to prevent sexually transmitted infections.
