This is a comparison of progestogens, or agonists of the progesterone receptor (PR), as medications. Progestogens include both progesterone and progestins (synthetic progestogens).

Pharmacology
Comparison of structural classes
The different structural classes of progestins have different pharmacological profiles. 19-Norprogesterone and retroprogesterone derivatives tend to be pure progestogens. 17?-Hydroxyprogesterone derivatives tend to have antiandrogen and glucocorticoid properties. Notable exceptions include hydroxyprogesterone caproate, which is a pure progestogen, and medroxyprogesterone acetate, which has weak androgenic actions. 17?-Ethynyltestosterone and 19-nortestosterone derivatives tend to possess weak androgenic actions. Gestodene is a 19-nortestosterone derivative with antimineralocorticoid properties. 17?-Spirolactones tend to have antimineralocorticoid and antiandrogen actions. Progesterone itself has potent antimineralocorticoid properties and very weak glucocorticoid actions.
