What is it?
An intrauterine device (IUD) is a small plastic and copper device that is fitted into the womb. The copper has an effect on the fluids within the womb and these changes prevent pregnancy.
How it works
An IUD works by stopping the sperm and egg from surviving in the womb or fallopian tubes. It may also prevent a fertilised egg from implanting in the womb.
An IUD is inserted by a trained doctor or nurse. It can stay in place for between five and 10 years, depending on the type used, although it can be removed earlier.
It is over 99% effective and instantly reversible once removed, which means that most women will be fertile again and potentially able to become pregnant immediately after the IUD has been removed.
The IUD can also be used as emergency contraception if fitted within five days of having unprotected sex.
We can advise on, and fit, IUDs.
