Percentage of free trials (top graph) and approach latencies (bottom graph) in Y maze tests during which castrated, testosterone propionate-treated male ferrets approached a goal box, which provided stimuli from either a sexually active stud male (to male) or an estrous female (to female). Subjects received Y maze tests before and again after they had received coital experience. *p < 0.05, comparisons with sham-occluded males; †p < 0.01, within-groups comparisons by post hoc Student–Newman–Keuls tests with sexually naive values obtained under the same stimulus conditions. Data are expressed as mean ± SEM.
