Open‐field test shows the effect of finasteride on exploratory behaviors in adolescent (A) and early developmental rats (B). **P < 0.01, *P < 0.05. It is shown that finasteride treatment at doses of 25 and 50 mg/kg significantly inhibits the exploratory behaviors in adolescent rats (A) in comparison with control group, while has no effect in early developmental rats (B).
