IUD / IUS

IUD / IUS

There are two different devices that can be fitted, both of which last for at least 5 years:

IUD

An IUD is a small plastic and copper device that is put into your uterus (womb). It has one or two soft threads on the end. These thin threads hang through the opening at the entrance of your uterus (cervix) into the top of your vagina.

There are different types and sizes of IUD to suit different women. An IUD can stay in for 5–10 years, depending on type. If you are aged 40 or older when the IUD is fitted, it can be left in until the menopause. It should only be fitted by a trained Doctor or Nurse. An IUD used is sometimes called a ‘coil’.

IUS

An IUS is a small T-shaped plastic device which slowly releases a progestogen hormone. This is similar to the natural progesterone that women produce in their ovaries.

A trained Doctor or Nurse will put the IUS into your uterus (womb). The IUS has two soft threads at one end which hang through the opening at the entrance of your uterus – cervix – into the top of your vagina.

The IUS available in the UK is called Mirena. It works for up to five years. If you are aged 45 or older when the IUS is fitted, it can be left in until the menopause or until contraception is no longer needed.
