Vaginal ring

What is the vaginal ring?

The vaginal ring, also known as the contraceptive ring, is a contraceptive method to avoid pregnancy. The ring sits inside the vagina and releases continuous doses of oestrogen and progestogen into the bloodstream to prevent pregnancy by preventing the ovaries from releasing an egg each month. The progestogen helps prevent sperm from entering the uterus by causing the mucus that exists in the cervix to thicken.

How successful a contraceptive method is the vaginal ring?

When used correctly, the vaginal ring is more than 99% effective in preventing pregnancy. An advantage of the ring, compared to other methods such as the contraception pill is that it will work if you have nausea or diarrhoea and does not require daily doses as the ring stays in place for a month at a time.

How does the vaginal ring work?

It is a flexible ring about five centimetres in diameter that is placed inside the vagina. It is a monthly contraceptive that must remain in the vagina for three weeks (21 days). You then have a 7-day ring-free break during which you will menstruate. During this week you are not protected against pregnancy. After the 7-day break you insert a new ring for the next 21 days. You can start to use the ring at any point in your menstrual cycle, and you will even be protected against pregnancy if you insert a ring on the first day of your period.
