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.[4] They are primarily used for the prevention of undesired pregnancy, although additional medical uses also exist.[5]

Progestogen-only pills differ from combined oral contraceptive pills (COCPs), which instead consist of a combination of synthetic estrogens and progestin hormones.[6]
