Etiocholanolone glucuronide (ETIO-G) is an endogenous, naturally occurring metabolite of testosterone.[1][2] It is formed in the liver from etiocholanolone by UDP-glucuronyltransferases.[1] ETIO-G has much higher water solubility than etiocholanolone and is eventually excreted in the urine via the kidneys.[1][2] Along with androsterone glucuronide, it is one of the major inactive metabolites of testosterone.[3][4]
