What does an IUD stand for?
IUD stands for Intrauterine Device (basically: a device inside your uterus). It’s a small piece of flexible plastic shaped like a T. Sometimes it’s called an IUC — intrauterine contraception.
What are the types of IUDs?
5 different brands of IUDs are FDA-approved for use in the United States:
- Paragard,
- Mirena,
- Kyleena,
- Liletta, and
- Skyla.
These IUDs are divided into 2 types:
- hormonal IUDs (Mirena, Kyleena, Liletta, and Skyla).
- copper IUDs (Paragard) and

The Paragard IUDs don’t have hormones. It’s wrapped in a tiny bit of copper, and it protects you from pregnancy for up to 12 years.
The Mirena, Kyleena, Liletta, and Skyla IUDs use the hormone progestin to prevent pregnancy. Progestin is very similar to the hormone progesterone that our bodies make naturally. Mirena works for up to 8 years. Kyleena has worked for up to 5 years. Liletta has worked for up to 8 years. Skyla has worked for up to 3 years.
How do IUDs work?
Both copper IUDs and hormonal IUDs prevent pregnancy by changing the way sperm cells move so they can’t get to an egg. If sperm can’t make it to an egg, pregnancy can’t happen.
The Paragard IUD uses copper to prevent pregnancy. Sperm doesn’t like copper, so the Paragard IUDs make it almost impossible for sperm to get to that egg.
The hormones in the Mirena, Kyleena, Liletta, and Skyla IUDs prevent pregnancy in two ways: 1) they thicken the mucus that lives on the cervix, which blocks and traps the sperm, and 2) the hormones also sometimes stop eggs from leaving your ovaries (called ovulation), which means there’s no egg for a sperm to fertilize. No egg, no pregnancy.
One of the awesome things about IUD’s 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’s anymore, your nurse or doctor can quickly and easily take it out. You’re able to get pregnant right after the IUD’s is removed.
Can IUDs be used as emergency contraception?
Yes! The Paragard, Mirena, and Liletta IUD’s work super well as emergency contraception. If you get one of these IUD’s put in within 120 hours (5 days) after unprotected sex, it’s more than 99% effective. It’s the most effective way to prevent pregnancy after sex.
Another great thing about using an IUD’s as emergency contraception: you can keep it and have effective birth control that you can use for up to 8 to 12 years (depending on which kind you get). The other kind of emergency contraception is the morning-after pill. You can take it up to 5 days after unprotected sex to reduce the risk of pregnancy.
