A vasectomy is a method of surgery that clamps, cuts or seals a man's vas deferens from each testicle to prevent sperm from mixing with the semen during ejaculation.
Your physician will explain the various methods and timelines that are common with the vasectomy procedure.
It can take several months after a vasectomy for any remaining sperm to be ejaculated or reabsorbed into surrounding tissue. You will have to use another method of birth control until you have a semen sample tested and it has a zero sperm count. Otherwise, you can still get your partner pregnant.
