Intrauterine System (IUS)
The IUS is a small plastic device that releases the hormone progesterone when it is put into the womb.
How it Works
It works in several different ways - by stopping the sperm from meeting the egg, by delaying the egg getting to the womb, or by preventing the egg from implanting in the womb.
It is important that you talk to a doctor who will assess what contraceptive option is best for you.
- Does not interrupt sex
- Works as soon as it is inserted
- Can stay in for three to five years
- Certain medication can interfere with its effectiveness. In this instance another method of contraception would have to be used
- May cause irregular bleeding for the first few months but after that time most women have lighter and often no periods.
- Insertion and removal must be done by a specifically trained doctor
