Tubal ligation (sometimes called female sterilization) is one of the most effective kinds of birth control. It’s permanent and more than 99% effective at preventing pregnancy.
How effective is sterilization?
Tubal ligation is really great at preventing pregnancy — more than 99% effective. This means that fewer than 1 out of 100 people who are sterilized will get pregnant each year. That’s as good as it gets when it comes to pregnancy prevention.
There are different types of sterilization. Essure takes about 3 months to start preventing pregnancy. That means if you get Essure, you need to use another method of birth control for the first 3 months, until your doctor or nurse gives you a test to makes sure it worked. The other kinds of tubal ligation work right away.
The reason why sterilization is so effective is that it protects you from pregnancy around the clock for the rest of your life without you having to do anything. So once you have the procedure and your doctor says it’s safe for you to have sex without any other birth control, that’s pretty much it — you don’t have to do anything else to prevent pregnancy. Sterilization is get-it-and-forget-it birth control.
