The only hormone-releasing intrauterine device (IUD) available in Australia is called Mirena®.
It is a small plastic device in the shape of a ‘T’ with a hormone called levonorgestrel in its stem. It is placed inside the uterus (womb) to prevent pregnancy. The IUD has a fine nylon string attached to it. When the IUD is in place, the string comes out through the cervix (the neck of the uterus) into the top end of the vagina. If you feel high up inside your vagina with your finger, you can check that the string is there and know the IUD is still in place. The string also makes it easy for a doctor to remove the IUD. The hormone-releasing IUD can stay in place for up to five years.
The hormone makes the mucus in the cervix thicker so that sperm cannot get into the uterus. Most women who want a reliable, long term contraceptive can use it. Dr Audrey Ting has been trained to insert the device.
