Vasectomy Risks and Benefits — What Every Man Should Know
Once you’ve made up your mind that you never want to have any more children, there’s no more reliable form of contraception than vasectomy.
A vasectomy is considered a permanent method of birth control. A vasectomy prevents the release of sperm when a man ejaculates.
During a vasectomy, the vas deferens from each testicle is clamped, cut, or otherwise sealed. This prevents sperm from mixing with the semen that is ejaculated from the penis. An egg cannot be fertilized when there are no sperm in the semen. The testicles continue to produce sperm, but the sperm are reabsorbed by the body. (This also happens to sperm that are not ejaculated after a while, regardless of whether you have had a vasectomy.) Because the tubes are blocked before the seminal vesicles and prostate camera.gif, you still ejaculate about the same amount of fluid.
It usually takes several months after a vasectomy for all remaining sperm to be ejaculated or reabsorbed. You must use another method of birth control until you have a semen sample tested and it shows a zero sperm count. Otherwise, you can still get your partner pregnant.
