Contraceptive vaginal ring
The contraceptive vaginal ring is a flexible, plastic ring that is placed in the vagina. It slowly releases the hormones oestrogen and progesterone. You place the ring in your vagina, leave it in place for 21 days, then remove it for seven days. You then replace it with a new ring for three weeks and repeat this routine every month. It is important to follow this routine to prevent an unwanted pregnancy. It is 99% effective when used correctly.
How does it work?
It stops the ovaries from releasing an egg and thickens the mucus found at the neck of the womb which acts like a cork and helps to prevent sperm entering the womb, which stops them meeting an egg. It also makes the lining of the womb thin, making it difficult for a fertilized egg to implant itself.
