Insertion of Intrauterine Device or Mirena
Intrauterine devices (IUD) and Mirenas are small, T-shaped devices placed inside the uterus (womb) to provide long-acting contraception.
An IUC, often called the "copper coil," is made of plastic and copper. It contains no hormones and can remain in place for 5 to 10 years, depending on the type.
A Mirena is made of plastic but slowly releases a hormone called levonorgestrel. It can last up to 5 years, and in some cases is used for longer depending on individual needs and medical guidance.
You may be offered an IUD or Mirena to:
• provide long-term, effective contraception
• reduce bleeding
• treat heavy or painful periods
• manage conditions like endometriosis or adenomyosis
• provide protection of the womb lining during hormone replacement therapy
What is involved in insertion?
You will lie on an examination couch. A speculum is used to gently open the vagina, and the device is inserted through the cervix into the uterus using a thin, flexible applicator.
Insertion is usually carried out in a clinic and takes about 10–15 minutes. Your gynaecologist will work with you to make sure that the insertion is as comfortable as possible. You may be offered a local anaesthetic or medicine to soften the cervix. Some people elect to have their IUD or Mirena inserted under general anaesthetic.
Once in place, a pair of fine threads will extend from the device into the top of the vagina. These are used to check the device is in place and for removal when needed.
