An IUD (intrauterine device) is a small T-shaped device placed inside the uterus to prevent pregnancy. It is a long-acting, reversible form of birth control and comes in hormonal and non-hormonal (copper) types.
A copper IUD releases copper into the uterus, which makes it hard for sperm to survive and for an egg to implant. A hormonal IUD, often called an IUS in the UK, releases a progestogen that thickens cervical mucus and thins the womb lining. Both types are over 99% effective.
An IUD can stay in place for several years, depending on the type. A doctor or nurse can remove it at any time, and fertility usually returns quickly after removal. A copper IUD can also be fitted as emergency contraception within five days of unprotected sex.
Fitting an IUD takes around 5 to 10 minutes and can be uncomfortable or painful. Afterwards some people have cramps or spotting for a few days. A copper IUD may make periods heavier or more painful, while a hormonal one often makes them lighter. Rare risks include infection, the device moving and damage to the uterus.
A GP, practice nurse or sexual health clinic can explain whether an IUD suits you and compare it with other birth control methods. An IUD does not protect against sexually transmitted infections, so condoms are still needed for that.
