Plasma hormones.

<p>(A) plasma androgen concentration in ng/ml before and 30 minutes after an injection with 5 μg GnRH. (B) plasma CORT concentration in ng/ml before and after being restrained for 10 minutes (backtransformed from Log10). (C) baseline plasma androgen concentration and (D) baseline plasma CORT concentrations in ng/ml of bald and non-bald pair-housed females, and bald and non-bald group-housed females. Data from bald pair-housed females are indicated by solid circles, but were not used in the statistical analyses. Data are shown as means ± 1 SEM. Numbers between brackets indicate sample sizes. ** = p < 0.01; * = p < 0.05; # = p < 0.1; ns = not significant.</p
