iudIUDs (Intrauterine Devices) are long term, reversible methods of birth control used to effectively prevent pregnancy. There are two types of IUDs: Hormonal and Non-Hormonal. Hormonal IUDs work by releasing hormones to prevent ovulation – the process when the ovaries release an egg – and thickening the cervical mucus. Paragard is made of copper which causes sperm to die within the uterus before it can fertilize an egg. Paragard contains no hormones.

How is it used?

An IUD is a T-shaped device that rests in the uterus.  The Hormonal IUDs work for up to 3- 5 years depending on the type. Paragard, the Non-Hormonal IUD, works up to 10 years.

How well does it work?

IUDs are more than 99% effective for 5-10 years. IUDs do not prevent against any STIs!

Where can someone get it?

IUDs must be inserted by a medical provider. It’s important to visit with a medical provider to ensure an IUD is right for you.
