Progestogen-only pill

Progestogen-only pills (POPs), colloquially known as "mini pills", are a type of oral contraceptive that contain synthetic progestogens (progestins) and do not contain estrogens. They are primarily used for the prevention of undesired pregnancy, although additional medical uses also exist.

Progestogen-only pills differ from combined oral contraceptive pills (COCPs), which consist of a combination of progestins and estrogens.
