The vaginal ring

Other names: contraceptive ring; hormonal ring


What is the vaginal ring?

The vaginal ring is a small, soft, plastic ring that you place in your vagina. It releases two hormones, an oestrogen and a progestogen into your bloodstream to prevent pregnancy.


Each ring lasts for 3 weeks followed by a 1-week break.

The contraceptive ring is a type of short-acting contraceptive


The contraceptive ring belongs to a category of contraceptives called short-acting contraception. Short-acting contraceptives need to be taken (or used) frequently – either every time you have sex, daily, weekly or monthly.


The vaginal ring is a type of short-acting contraception called a short-acting hormonal contraceptive. The combined pill, the progestogen-only pill, the patch and the vaginal ring are all examples of short-acting hormonal contraception.

How does the vaginal ring work?

Once inserted into the vagina, the contraceptive ring slowly releases the hormones progestogen and oestrogen into your body and prevents pregnancy in two ways:


Stops the ovaries from releasing eggs (ovulation).


Thickens the cervical mucus, which keeps the sperm from getting to the egg.

How effective is the vaginal ring at preventing pregnancy?

The ring is 91% effective at preventing pregnancy with typical use but can be more than 99% effective when used correctly (perfect use). Inserting the ring incorrectly, forgetting to change or insert your new ring on time, the ring breaking or, the ring falling out can make this method of contraception less effective.
