In a mutual viewing test environment, gonadectomized Ss maintained their aggressive behavior on all 6 indices of aggression at a level equal to controls. Ss that showed some testis regeneration and sham-operated Ss were also equal to controls. Results are interpreted to mean that adult aggressive behavior in males of this species may not be under the control of gonadal hormones. Pituitary gonadotropins, interrenal gland, and critical period hypotheses are given as possible explanations of the maintained aggressiveness following castration.
