IUCDs

Dr Jenny Cook | Sydney Gynaecologist & Advanced Laparoscopic Surgeon

What is an IUD/IUCD?

An IUCD (intra-uterine contraceptive device) is a popular type of long acting, reversible contraception. A Mirena^TM is an IUCD which releases progesterone (levonorgestrel) to the uterus, it is also often used to treat heavy and painful periods. There are also non-hormonal IUCDs.

This contraceptive device can be inserted as an outpatient (in rooms). This is best performed during menstruation. Insertion as an outpatient is most suitable for a woman who has had a vaginal delivery, as the cervical opening will be slightly larger. A woman who has never had a vaginal delivery may find this procedure very painful, if not impossible. For these women, it is possible to insert the contraceptive device under sedation as a Day Stay procedure.

A progesterone-releasing IUD (levonorgestrel) is particularly popular, as it not only prevents pregnancy but also helps treat heavy and painful periods.

IUD Insertion

The contraceptive device can be inserted as an outpatient procedure, usually best performed during menstruation.

The IUD Insertion Procedure

During the procedure, Dr Cook will ask you to lie on your back, similar to a Pap smear. A speculum is inserted, the cervix is cleaned with a special solution, and then gently dilated. The IUD is carefully placed into the uterus. The process takes about 4 minutes in total.

What to Expect After Your IUD Insertion

Most women will experience mild pelvic cramps for about 24 hours, which can usually be managed with Panadol. Light bleeding may occur for a few days. To reduce the risk of infection, it is best to avoid intercourse, tampons, baths, and swimming for 48 hours after insertion.

If you decide that the IUD is not right for you, it can be easily removed. The device is effective for up to 5 years.

Potential Side Effects of IUDs

Some women may feel extreme dizziness (vaso-vagal response) at the time of insertion, which usually passes within minutes.
Periods often become lighter but may last longer.
Irregular bleeding or spotting is common in the first 3–6 months but generally settles by 6 weeks.
In the long term, 95% of women experience lighter, less painful periods, and around 30% stop menstruating altogether while the IUD is in place.
