Progestogen-only injectable contraception is a hormonal type of contraception that is given through an injection. It contains a synthetic form of the hormone progesterone, known as progestin or progestogen. They provide protection against pregnancy for up to 8 to 14 weeks.
Types
- Medroxyprogesterone acetate (DMPA)
- Norethisterone enanthate (NET-EN)
Mechanism of action
- This hormone works primarily by suppressing ovulation (preventing the release of an egg from the ovaries).
- It also thickens cervical mucus, making it more difficult for sperm to reach and fertilize an egg.
- It can thin out the uterine lining, making it less suitable for the development of the fertilized egg.
