Researchers have developed Annovera, a highly effective contraceptive vaginal ring, which has a self-inserted system and can be used for an entire year. The details were presented in the Endocrine Society's Annual Meeting.

The ring is left in place for 21 days and removed in 7 days in each cycle. It provides contraceptive efficacy for up to 13 cycles (1 year) of use. It is designed to release 150 mcg segesterone acetate (medication used for birth control) and 13 mcg ethinyl estradiol (a medicine used to prevent pregnancy) has a failure rate, of 2.98.

Vaginal rings give 97 percent success rate is comparable to the most effective birth control methods already on the market, which are at least 95 percent effective.
