11-Ketotestosterone is an oxidized form of testosterone that contains a keto group at position-11. It is related to adrenosterone, an androgen found in trace quantities in humans. In fish, 11-ketotestosterone functions as the endogenous androgenic sex hormone.[1][2] In midshipman fish, 11-ketotestosterone is not present in females or Type II Males - Type II Males reach sexual maturation later, are less territorial, and have higher testosterone than Type I Males.
