A vasectomy is a permanent form of birth control. The procedure involves cutting the vas deferens, which are the two tubes that carry sperm from the testicles. This prevents sperm from being released during ejaculation.
Most men can return to their normal activities the day after the procedure. However, it is important to avoid strenuous activity for at least a week. This includes lifting heavy objects, running, and sexual intercourse.
It takes about two to three weeks for the body to clear all of the sperm from the vas deferens. Until this happens, there is still a small chance of pregnancy. For this reason, it is important to use another form of birth control during this time period.
After the procedure, your doctor will likely schedule a follow-up appointment to check that everything is healing properly. You should also have a semen analysis six to 12 weeks after the vasectomy to ensure that there are no sperm present.
