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]
