Copper bearing intrauterine device (IUD) (the coil)

The IUD is a small, usually T-shaped plastic device which contains copper. The IUD 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.
