Copper bearing intrauterine device (IUD) (the coil)
The IUD is a small, T-shaped plastic device which contains copper, which is put into the womb through the vagina by a specially trained doctor or nurse.
The IUD is different to the intrauterine system (IUS). The IUS has hormones in it; the IUD does not.
The copper in the device disables the sperm, and stops the sperm reaching the egg, which prevents fertilisation. It may also stop a fertilised egg implanting in the womb. It can stay in place and prevent pregnancy for between 5 and 10 years, depending on the type of device.
The IUD is over 99% effective and is the only LARC method that doesn’t have hormones in it.
There are three different types of IUD.
