IUDs - Effective Birth Control Methods 

IUDs are one of the best birth control methods out there — more than 99% effective. That means fewer than 1 out of 100 people who use an IUD will get pregnant each year.

IUDs are so effective because there's no chance of making a mistake. You can’t forget to take it (like the pill), or use it incorrectly (like condoms). And you're protected from pregnancy 24/7 for 3 to 12 years, depending on which kind you get. Once your IUD is in place, you can pretty much forget about it until it expires.

Yes! The Paragard, Mirena, and Liletta IUDs work super well as emergency contraception. If you get one of these IUDs put in within 120 hours (5 days) after unprotected sex, it’s more than 99% effective. It’s actually the most effective way to prevent pregnancy after sex.

Another great thing about using an IUD as emergency contraception: you can keep it and have really effective birth control that you can use for up to 8 to12 years (depending on which kind you get). The other kind of emergency contraception is the morning-after pill.

One of the awesome things about IUDs is that they last for years — but they’re not permanent. If you decide to get pregnant or you just don’t want to have your IUD anymore, your nurse or doctor can quickly and easily take it out. You’re able to get pregnant right after the IUD is removed.
