11-oxo Etiocholanolone is a metabolite of cortisol and 11-keto testosterone.1,2 It is formed from cortisol via cortisone and tetrahydrocortistone intermediates, and it is formed from 11-keto testosterone via 5β-11-keto dihydrotestosterone and 3α-11-keto etiocholanediol intermediates. Urinary levels of 11-oxo etiocholanolone increase during pregnancy and are elevated in patients with uterine leiomyomas.3,4 Fecal levels of 11-oxo etiocholanolone have been used as a marker of stress in domestic livestock and free-range ruminants.5
