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.
雌性橙腹田鼠的尿液含有一种化学信号，可抑制其他雌性的生殖成熟。与雄性接触后受到刺激的未孕雌性的子宫增大，会因随后与另一只雌性接触或在鼻子上涂抹雌性尿液而受到抑制。受到这种抑制的雌性无法进入发情期。来自未孕的同胞和非同胞雌性以及怀孕雌性的尿液都具有这种抑制作用。
