Hormonal coil (IUD)
The hormonal coil (IUD) is made of plastic and releases the hormone progestogen.
It has to be put into your womb (uterus) by a specially trained doctor or nurse and can last up to 8 years.
How does it work?
- It thins the lining of your womb, so a fertilised egg can’t grow.
- It thickens the mucus in your cervix, making it harder for sperm to reach an egg.
Why choose it?
- It’s super effective and lasts for several years.
- It’s known as long-acting reversible contraception (LARC) or “fit and forget” because you don’t have to think about it every day.
Benefits of the Hormonal IUD
