CHAPTER 7 - Combined Vaginal Ring: Only the Essentials
- A flexible ring placed in the vagina.
- Continuously releases 2 hormones—a progestin and an estrogen, like the natural hormones progesterone and estrogen in a woman's body—from inside the ring. Hormones are absorbed through the wall of the vagina directly into the bloodstream.
- The ring is kept in place for 3 weeks, then removed for the fourth week. During this fourth week the woman will have monthly bleeding.
- Also called NuvaRing.
- Works primarily by preventing the release of eggs from the ovaries (ovulation).
