Mean (± SEM) number RMEs performed by male rats injected daily with sesame oil (Sham and GDX) or one of four doses of testosterone propionate during 5-day blocks of trials over 25 days of testing in an 8-arm radial maze (n = 13-15/group). (A) Comparing the Oil Sham to the Oil GDX group revealed no effects of blocks or castration. (B) Comparing the Oil GDX group to the testosterone-treated groups demonstrated a significant changes over the five testing blocks (p = 0.012). (C) There was no significant effect of treatment on RMEs. There were also no significant differences between groups when the testing blocks were analyzed separately.
