Male rat pups are more hesitant to urinate in response to anogenital stimulation than are their female sibs.
Male rat pups required more anogenital stimulation before they began to urinate than did their sisters and males produced more urine than their female sibs during a fixed period of anogenital stimulation. These findings are interpreted as consistent with the view that neonatal mammals can manipulate the behavior of their dams.
