Non-Hormonal (Copper) Coil/IUD
The non-hormonal coil – also known as a Copper Coil or Copper IUD – is a small T-shaped device made of plastic and copper.
It’s put into your womb (uterus) by a specially trained doctor or nurse, and prevents pregnancy by:
- slowly releasing copper which is toxic to sperm
- stopping fertilised eggs embedding in the womb
The Copper IUD is popular because it has no hormones and is a long-acting reversible method of contraception – contraception you don’t have to think about.
- The copper IUD can last for 5-10 years – depending on the type.
- It has to be fitted by a specially trained doctor or nurse.
- The copper IUD contains no hormones.
- You may have some side effects when first fitted – spotting and cramps – but these usually improve after a few weeks.
- When fitted correctly, the Copper IUD is 99% effective at preventing pregnancy.
- The copper IUD can also be used for emergency contraception for up to five days after unprotected sex.
- You can have an IUD removed at anytime and your fertility will return to normal.
- The copper IUD does not protect against STIs – so you’ll still need to use condoms.
- Please note, the copper IUD can change your periods making them heavier, longer or more painful.
Copper IUDs can only be fitted by specially trained doctors or nurses.
It can sometimes be painful having an IUD fitted but pain relief can be given.
It can be fitted in:
- Sexual health clinics
- Some GPs
If you are having your IUD fitted within a sexual health clinic, you will need to sign a consent form.
