PROJECT
Progesterone Ring for Lactating Women

The vaginal ring is a pliable drug-delivery system that can be inserted into the vagina, where it slowly releases hormones that are absorbed into the bloodstream. About 2¼" in diameter and the size of the outer rim of a diaphragm, the contraceptive ring is an easy-to-use, reversible method that may have advantages over other methods.

This ring uses the natural hormone progesterone. While not an effective contraceptive method for cycling women, it can be used by nursing women to extend the contraceptive effectiveness of lactation. The Council developed and carried out extensive studies with a progesterone ring in 900 women in eight countries. The method was well accepted and effectively protected women from pregnancy. A Chilean company is currently manufacturing and distributing this ring in Chile and Peru. The ring may also be used for hormone therapy in women who require a progestin.
