The conversion of testosterone (TEST) to the most potent androgen, 5-alpha-dihydrotestosterone (DHTEST), is catalyzed by microsomal 5alpha-steroid reductase 3 (SRD5A3) (Uemura et al. 2008). SRD5A3 is expressed in the prostate and other androgen target sites. Corticotropin (Adrenocorticotropic hormone, ACTH) acts through melanocortin receptor type 2 (MC2R) to stimulate steroidogenesis, increasing the production of androgens (McKenna et al. 1997).
