- An IUD (intrauterine device), also called a copper coil, is a small plastic T-shape that a doctor or nurse puts into your womb (uterus).
- It does not use hormones. It stops pregnancy by releasing copper into the womb.
- An IUD is not suitable for everyone.
- An IUD is over 99% effective.
- It works as soon as it's put in and lasts for 5 or 10 years, depending on the type.
- An IUD can also be used as a form of emergency contraception.
- It’s safe to use while breastfeeding.
- After an IUD is removed your fertility will return to previous levels straight away.
- This information is about the copper coil. For information about the hormonal coil, see intrauterine system (IUS).
- You can compare different methods, including how well they work and side effects, when choosing a method of contraception.
Information:
An IUD does not stop you getting or passing on sexually transmitted infections (STIs). Use a condom every time you have sex to protect you and your partner against STIs including HIV.
