Although an IUD is an effective method of contraception, there are some things to consider before having one fitted.
Advantages of an IUD
- Most women can use an IUD, including women who have never been pregnant.
- Once an IUD is fitted, it is immediately effective at preventing pregnancy for up to 10 years or until it's removed.
- It doesn't interrupt sex.
- It can be used if you're breastfeeding.
- Your normal fertility returns as soon as the IUD is taken out.
- It's not affected by other medicines.
There's no evidence that having an IUD fitted will increase the risk of cancer of the cervix, endometrium (lining of the womb) or ovaries. Some women experience changes in mood and libido, but these are very small.
Disadvantages of an IUD
- Your periods may become heavier, longer or more painful, though this may improve after a few months.
- You must have an internal examination to check whether an IUD is suitable for you, and another examination when it is fitted.
- An IUD doesn't protect against sexually transmitted infections (STIs), so you may have to use condoms as well. If you get an STI while you have an IUD fitted, it could lead to a pelvic infection if left untreated.
The most common reasons that women stop using an IUD are vaginal bleeding and pain.
