5α-Dihydrodeoxycorticosterone (abbreviated as DHDOC), also known as 21-hydroxy-5α-pregnan-20-one, is an endogenous progestogen and neurosteroid.^[1] It is synthesized from the adrenal hormone deoxycorticosterone (DOC) by the enzyme 5α-reductase type I.^[1] DHDOC is an agonist of the progesterone receptor, as well as a positive allosteric modulator of the GABA_A receptor, and is known to have anticonvulsant effects.^[1][2]
