Vaginal ring | NHS inform
A woman can get pregnant if a man’s sperm reaches one of her eggs (ova). Contraception tries to stop this happening by keeping the egg and sperm apart or by stopping egg production. One method of contraception is the vaginal ring. The vaginal ring is a small, soft plastic ring that you place inside your vagina. It’s about 4mm thick and 5.5cm in diameter. You leave it in your vagina for 21 days. Then you remove it and throw it in the bin (not down the toilet) in a special disposal bag. Seven days after removing the ring, you insert a new one for the next 21 days. The ring releases oestrogen and progestogen. This prevents ovulation (release of an egg), makes it difficult for sperm to get to an egg and thins the womb lining, so it’s less likely that an egg will implant there. If used correctly, the vaginal ring is more than 99% effective. This means that fewer than 1 woman out of every 100 who use the vaginal ring as contraception will become pregnant in one year.
