What Is Depo-Provera?
How Does Depo-Provera Work?
Depo-Provera contains the female hormone progestin. Progestin prevents pregnancy by preventing ovulation (the release of an egg from the ovary). If a woman doesn’t ovulate there’s no egg to meet the sperm and no pregnancy can happen.
Depo-Provera also thickens cervical mucus, which helps prevent sperm from getting through. If the sperm can’t get through, it can’t reach an egg, and pregnancy cannot occur.
