IUD
How reliable is it?

How it works
- A small plastic and copper device is put into the womb. It stops sperm meeting an egg or may stop an egg settling in the womb.
Advantages
- Works as soon as it is put in.
- Can stay in for a minimum of 5 years.
Disadvantages
- Periods maybe heavier or longer and more painful.
- unsuitable for women who have heavy painful periods.
- Not a first choice for women who might be at risk of a sexually transmitted disease
Comments
