What is the intrauterine system?
The hormonal intrauterine system (IUS) is a small, plastic T-shaped device with a cylinder around its stem that releases the hormone progestogen. The hormonal IUS is placed inside the uterus by a doctor.
How long does the IUS last?
The IUS can remain in place for up to 5 years.
How does the IUS work?
The IUS continuously releases a small amount of the hormone progestogen to prevent pregnancy by changing the cervical mucus and preventing fertilisation and implantation.
The use of the IUS does not affect future fertility and about 80% of women wishing to become pregnant will conceive within 12 months following the removal of the IUS. Your doctor will also be able to answer any questions you may have about the hormonal IUS.
