Depo-Provera is a brand name for medroxyprogesterone acetate, which is a contraceptive injection that contains progestin. It acts by suppressing your ovulation and thus preventing your ovaries from releasing eggs. On top of that, Depo-Provera keeps the sperm from reaching the egg by thickening your cervical mucus.
Depo-Provera is done in cases when you don’t want to take a birth control pill every day, you want to avoid using estrogen, and in cases when the patient has health issues such as seizures, anemia, and sickle cell disease. Usually, Depo-Provera is given every three months, and in a year of typical use, only six out of a hundred women will get pregnant. This risk is significantly reduced in women who get the injection every three months.
