Metabolite Identification
Common NameDihydroandrosterone
DescriptionDihydroandrosterone is a major metabolite of testosterone. Dihydroandrosterone is the main steroid produced by the immature ovary; at puberty the synthesis of steroids shifts toward 4-ene-3-oxo steroids. testosterone 5a-reduced metabolites, including dihydrotestosterone are produced in the anterior pituitary and the central nervous system. Anabolic androgen steroid (AAS) are one of primary performance-enhancing substances abused by athletes. To defeat doping controls, athletes changed to take endogenous androgens from the application of synthetic AAS. testosterone was one candidate of endogenous androgens abused in sports. testosterone and its relevant steroids in urine is detected and monitored with GC/MS. The abuse of anabolic-androgenic steroids (AS) is a growing problem; however, the effects and mechanisms underlying their addictive effects are not well understood.
