Contraceptive vaginal ring


A Contraceptive vaginal ring is a type of hormonal insert that is placed in the vagina for the purpose of birth control. It consists of either both oestrogen and progesterone, the ethinylestradiol/etonogestrel vaginal ring, or just progesterone, the progesterone vaginal ring.

Combined hormonal contraceptive vaginal ring

The combined hormonal contraceptive, vaginal ring, is also known as NuvaRing. It is a flexible plastic ring that releases a low dose of a progestin and estrogen over three weeks.
About 8% of women using a vaginal ring will still get pregnant every year, although this drops to 1% with correct use. There is a small chance of blood clots, heart attacks and stroke with vaginal rings, and they are not recommended for women over 35 who smoke.
A one-year combined hormonal contraceptive ring, marketed as Annovera, was approved in the United States in 2018. It is a silicone elastomer vaginal ring containing the progestin segesterone acetate and the estrogen ethinyl estradiol.

Progesterone only vaginal ring

A progesterone vaginal ring has also been developed. It is specifically made for use during breast feeding as it does not affect milk production.
