The effects of anabolic-androgenic steroid (AAS) compounds on spatial
working memory were evaluated in male rats. Thirty days of administrat
ion of a high dose of three individual AAS compounds (17 alpha-methylt
estosterone, methandrostenolone, or testosterone cypionate) had no eff
ects on spatial memory or motivation as tested on a delayed non-match-
to-sample radial arm maze task. Administration of these AAS compounds
at doses within the human abuse range does not impair spatial working
memory in rats.
