Hormonal IUDs - Dr Eileen Sables

Dr Eileen Sables from Tend Pakuranga walks us through what the hormonal IUD looks like.

The hormonal or progestogen-only IUD contains a progestogen called levonorgestrel that it releases slowly into the womb. It does not protect against STIs.

How does it work
- It prevents fertilisation of the egg by damaging or killing the sperm.
- It also affects the lining of the uterus, making it unsuitable for a fertilised egg to implant and grow.
- Progestogen hormones in this IUD also reduce menstrual bleeding and cramping. Because of this, it is often used to treat heavy periods.

How effective is it?
- IUDs are more than 99% effective.
- Mirena® is effective for 5 years
- While Jaydess® is effective for 3 years
- At the end of this time, your IUD will need to be changed.
- You can decide to have your IUD taken out at any time.
