Progestogen-only contraception
Progestogen-only contraception (or progestin-only contraception) relies on progestogens alone to achieve contraception.[1] It is one of the two major types of hormonal contraception, with the other major type being combined hormonal contraceptive methods (including both estrogen and a progestogen).[1] There are several progestogen only contraceptive methods:[1]
- Progestogen-only pills ("mini-pills") (e.g., desogestrel, norethisterone)
- Progestogen-only emergency pills ("day-after pills") (e.g., levonorgestrel)
- Progestogen-only implants (e.g., etonogestrel implant, levonorgestrel implant)
- Progestogen-only injectables (e.g., medroxyprogesterone acetate, norethisterone enanthate)
- Progestogen-only intrauterine devices (e.g., levonorgestrel, progesterone)
