title: Suppression of reproductive maturation in male-stimulated virgin female microtus by a female urinary chemosignal.
abstract: Urine from female Microtus ochrogaster possesses a chemosignal that suppresses reproductive maturation in other females. Uterine enlargement in virgin females stimulated by a male was suppressed by subsequent association with another female or by application of female urine on the nose. Females so suppressed are not able to achieve estrus. Urine from virgin sibling and non-sibling females and from pregnant females possesses the suppressing effect.
