The Annovera ring is a combined hormonal contraceptive and the first vaginal ring to provide effective contraception for an entire year, or 13 cycles. It is left in place inside the vagina for 21 days, where it releases a daily dose of 150 mcg segesterone acetate and 13 mcg ethinyl estradiol, and then is removed for seven days, during which time women may experience a period.
Segesterone acetate is a new progestin that specifically binds to progesterone receptors and, unlike other combination hormone birth control products, has no estrogenic or androgenic activity. In the recent clinical trial, researchers reviewed data from earlier trials which measured how long segesterone stayed in a woman's bloodstream and at what levels.
The findings, which were presented on Tuesday at ENDO 2019, the Endocrine Society's annual meeting in New Orleans, USA, showed that segesterone acetate serum levels above 105 pmol/L had successfully inhibited ovulation in the early trials.
