社会环境影响雌性家鼠的生殖生理和性行为。全雌性的环境往往会抑制发情周期，而雄性的存在则会诱导并同步性接受。然而，不同种类的啮齿动物对社会环境的生殖反应可能不同。在建造土墩的雌性老鼠，Mus spicilegus中，性接受期被成年雌性表现出阴道闭合的时期所打断。研究了不同的社会环境对成年雌性细纹田鼠阴道口和发情状态的影响。结果表明，当雌性被分组时，它们的阴道通常是关闭的，但当它们被隔离或与性伴侣住在一起时，阴道会打开。当雌性与雄性共处一室时，它们会有性接受，但当它们被隔离时，它们的子宫颈涂片不能达到发情的特征。因此，在雌性spicilegus中，雄性的存在对发情有刺激作用。此外，与雌性同居对阴道开放有抑制作用。(C) 2003爱思唯尔科学有限公司版权所有。
Social environment influences the reproductive physiology and sexual behaviour of the female house mouse Mus musculus. An all-female environment tends to suppress the oestrous cycles, whereas the presence of a male induces and synchronises sexual receptivity. However, reproductive responses to social environment may differ among the various species of rodents. In mound-builder female mice, Mus spicilegus, periods of sexual receptivity are interrupted by periods where adult females display a vaginal closure. We investigated the influence of different social environments on the vaginal opening and oestrous state of adult female M. spicilegus. Result showed that when females were grouped their vaginas were generally closed but that vaginal opening occurred when they were isolated or housed with a, sexual partner. Females became sexually receptive when housed with a male, but when isolated their cervical smears did not reach characteristics of the oestrus. In female M. spicilegus, male presence thus has a stimulating effect on oestrous induction. Furthermore, cohabitation with females has an inhibiting effect on vaginal opening.
