Contraceptive vaginal ring
(Nuvaring ®)
91% effective
This is a small flexible plastic ring which a woman can easily insert into her vagina. It stays in place for 3 weeks, and is removed for one week during which a period will occur. A new ring is inserted after that. It contains the same hormones as the combined oral contraceptive pill, but they are released into the vagina instead of the gut.
