Vasectomy — also called male sterilization — is a surgical procedure. It is meant to protect against pregnancy permanently, so it’s super effective.
What is a vasectomy?
A vasectomy is a simple surgery done by a doctor in an office, hospital, or clinic. The small tubes in your scrotum that carry sperm are cut or blocked off, so sperm can’t leave your body and cause pregnancy. The procedure is very quick, and you can go home the same day. And it’s extremely effective at preventing pregnancy — almost 100%.
Vasectomies are meant to be permanent — so they usually can’t be reversed. You should only get a vasectomy if you’re 100% positive you don’t want to be able to get someone pregnant for the rest of your life.
The term “vasectomy” comes from the name of the tubes in your scrotum that are blocked during the procedure: vas deferens.
How does a vasectomy work?
Sperm — the microscopic cells that join up with an egg to cause pregnancy — are made in your testicles. Sperm leaves the testicles through two tubes called the vas deferens, and mixes with other fluids to make semen (cum). The sperm in your semen can cause pregnancy if it gets into a vagina.
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. But you’ll still have the same amount of semen you did before. There just won’t be any sperm in it.
Vasectomies don’t change the way having an orgasm or ejaculating (cumming) feels. Your semen (cum) will still look, feel, and taste the same after a vasectomy — it just won’t be able to get anybody pregnant.
