Dimethandrolone (DMA), also known by its developmental code name CDB-1321, is an experimental androgen/anabolic steroid (AAS) and progestogen medication which is under investigation for potential clinical use.[1][2][3]

Dimethandrolone is an AAS, and hence is an agonist of the androgen receptor, the biological target of androgens like testosterone.[1] It is also a progestin, or a synthetic progestogen, and hence is an agonist of the progesterone receptor, the biological target of progestogens like progesterone.[1] Due to its androgenic and progestogenic activity, dimethandrolone has antigonadotropic effects.[1] It has no estrogenic activity.[1][4]

Dimethandrolone was first described in 1997.[5] It was developed by the Contraceptive Development Branch of the National Institute of Child Health and Human Development, an agency in the United States government.[1][6]

An ester and prodrug of dimethandrolone, dimethandrolone undecanoate (DMAU) (CDB-4521), is under development for potential use as a birth control pill for men and in androgen replacement therapy for men.[1][2][3][7]
