Contraceptive vaginal ring is a type of insert that is placed in the vagina for the purpose of birth control.
A number of types exist. One type is the ethinylestradiol/etonogestrel vaginal ring, also known as NuvaRing. It is a flexible plastic (ethylene-vinyl acetate copolymer) ring that releases a low dose of a progestin and estrogen over three weeks. It is currently used by approximately 1.5 million women worldwide.
A progesterone vaginal ring has also been developed. It is specifically made for use during breast feeding as it does not affect milk production.
