Classification by structure Progestins used clinically (and/or in veterinary medicine) can be broadly categorized by chemical structure as follows:<ref name="pmid19434889">{{#invoke:ParseVauthors|parse}}</ref><ref name="ArtiniGenazzani2001">{{#invoke:citation/CS1|citation |CitationClass=book }}</ref>


The different structural classes of progestins have different pharmacological profiles. 19-Norprogesterone and retroprogesterone derivatives tend to be pure progestogens. 17α-Hydroxyprogesterone derivatives tend to have antiandrogen and glucocorticoid properties. A notable exception is hydroxyprogesterone caproate, which is a pure progestogen. Another notable exception is medroxyprogesterone acetate, which has weak androgenic actions. 17α-Ethynyltestosterone and 19-nortestosterone derivatives often possess weak androgenic actions.<ref name="BoxtelSantoso2008">{{#invoke:citation/CS1|citation |CitationClass=book }}</ref><ref name="GomelBrill2010">{{#invoke:citation/CS1|citation |CitationClass=book }}</ref> Gestodene is a 19-nortestosterone derivative with antimineralocorticoid properties. Spirolactones tend to have antimineralocorticoid and antiandrogen actions. Progesterone itself has antimineralocorticoid properties and very weak glucocorticoid actions.
