Overview. Vasectomy is a form of male birth control that cuts the supply of sperm to your semen. It's done by cutting and sealing the tubes that carry sperm. Vasectomy has a low risk of problems and can usually be performed in an outpatient setting under local anesthesia.

What happens to a man when he gets a vasectomy?

A vasectomy blocks or cuts each vas deferens tube, keeping sperm out of your semen. Sperm cells stay in your testicles and are absorbed by your body. Starting about 3 months after a vasectomy, your semen (cum) won't contain any sperm, so it can't cause pregnancy.

Do you still have balls after a vasectomy?

Regardless of the anesthesia, the procedure is the same. The physician will disconnect the vas deferens—the tubes that transport sperm from the testicles. After the surgery, sperm will not be able to leave the testicles.
