FDA approvals for Annovera and Natural Cycles app

On August 10, 2018, the U.S. Food and Drug Administration made two major announcements related to contraception. First, it permitted marketing of Natural Cycles, a direct-to-consumer app for contraceptive use. Then it approved AnnoveraTM, a combined hormonal contraceptive ring.


Natural Cycles uses an algorithm to calculate the days of the month a woman is likely to be fertile based on daily basal body temperature readings and menstrual cycle information. This fertility-awareness based method is designed for use on mobile devices, among pre-menopausal women aged 18 and older.


Annovera is the first vaginal ring that provides pregnancy protection for a year. It is used for three weeks and then removed for one week, allowing for a withdrawal bleeding period. Annovera, which includes segesterone acetate and ethinyl estradiol, was developed by the Population Council and will be marketed by TherapeuticsMD in the United States.
