An IUS is a small plastic device that’s put into your uterus (womb) and releases a progestogen hormone. This is similar to the natural progesterone produced by the ovaries.
The IUS works as contraception for three, five or six years depending on the type.
There are different types and sizes with different amounts of the progestogen hormone.
If you’re aged over 45 when a particular type of IUS (Levosert/Benilexa or Mirena) is fitted, it’ll work as contraception until after the menopause when contraception isn’t needed. Read more about the IUS…
