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