What is it?

A form of contraception. A small, T-shaped plastic and copper device that is placed in the uterus, via the cervix. It has two thin plastic threads that hang down to the top of the vagina.

How does it work?

It releases copper into the uterus. This alters the cervical mucus, which makes it more difficult for sperm to reach the egg. It also makes it more difficult for a fertilized egg to implant.

How long does it last?

Depending on which IUD is used, either 5 or 10 years.

When can it be inserted?

It can be inserted at any point in the menstrual cycle.

It can be inserted 4 weeks after giving birth.

It can be fitted immediately after a miscarriage or abortion.

Old wives tales

• That it increases weight and increases the risk of certain cancers.
• There is no evidence that an IUD affects weight or increases the risk of cancer.
• There are however links between prolonged use of ‘the pill’ and cancer.
