The IUD (intrauterine device, coil)

Intrauterine contraceptive options

There are two types of intrauterine contraception, the IUD (intrauterine device) and the IUS (intrauterine system). Although they look similar, they work in different ways as the IUS is a hormonal method of contraception. The IUD can be used as emergency contraception, as well as a long-term method of contraception which is not the case with the IUS. You can find out about the IUD as emergency contraception here.

The IUD (intrauterine device, coil)

This is a small plastic and copper T-shaped device which is inserted into the womb by a trained doctor or nurse. It prevents sperm from meeting the egg and may also prevent an egg from settling in the womb.

It has two little threads that lie inside the vagina so that you can check it's in place by giving a gentle tug.

With the IUD your periods may become heavier, longer or more painful.

Different types of IUD have to be changed at different intervals of between 3 - 10 years. When you don't want to use this method any more, you need to make an appointment with your health professional to have it removed. After it has been removed, you can get pregnant right away.
