The shot for preventing pregnancy is commonly known as Depo-Provera.
Understanding Depo-Provera
Depo-Provera is a brand name for a contraceptive injection that contains medroxyprogesterone acetate, a synthetic progestin hormone. This hormone works by preventing ovulation (the release of an egg from the ovaries), thickening cervical mucus (making it difficult for sperm to reach the egg), and thinning the lining of the uterus (making it less likely for a fertilized egg to implant).
How Depo-Provera Works:
- Prevents Ovulation: The primary mechanism of action is suppressing the release of an egg, thus preventing fertilization.
- Thickens Cervical Mucus: This acts as a barrier, making it harder for sperm to enter the uterus.
- Thins Uterine Lining: Reduces the likelihood of a fertilized egg implanting and developing.
