How does it work?
- A small T shaped plastic device inserted into the uterus (womb) which slowly releases the hormone progestogen. This stops 1 in 5 women ovulating or releasing an egg each month but it’s main effects are thinning the lining of the womb so a fertilised egg can’t implant and thickening the mucus in the cervix ( neck of the womb) to prevent sperm reaching the egg.
- The coil is inserted into the womb by a nurse or doctor trained in this procedure.
What’s good about it?
- Over 99% effective.
- Works for 3-5 years.
- Periods usually become lighter, shorter and sometimes less painful.
- Easily removed by your GP when needed.
- When it’s removed your fertility (ability to get pregnant) will return to normal.
What might the disadvantages be?
- You may get irregular bleeding for the first 6 months.
- Periods may stop altogether.
- Very small risk of infection after insertion.
Where can I get it?
- You can get get it from your GP or local sexual health clinic.
