在生殖幼稚的女性草原田鼠（Microtus ochrogaster）直接接触男性尿液或住房在男性弄脏的笼子里，在没有身体接触的情况下，导致子宫重量增加，但没有可靠地引起行为发情（由脊柱前凸定义）。与不熟悉的雄性动物身体接触1小时或更长时间，然后连续进入雄性动物污染的笼舍30或48小时，在约三分之二的受试雌性动物中诱导脊柱前凸。当女性身体暴露于男性18小时，6小时后进行测试，70%的人表现出脊柱前凸。然而，当将接受1或18小时雄性接触的雌性动物从雄性动物面前移开并置于干净的笼中24小时时，仅29-37%的雌性动物随后显示脊柱前凸。这些结果表明，与雄性的直接物理接触或来自雄性的化学刺激可能是诱导和维持雌性草原田鼠行为发情所必需的。
In reproductively naive female prairie vole (Microtus ochrogaster) direct contact with male urine or housing in a male-soiled cage, in the absence of physical contact, resulted in increased uterine weights, but did not reliably elicit behavioral estrus (defined by lordosis). Physical contact with an unfamiliar male, for 1 hr or more, followed by 30 or 48 hr of continuous access to a male-soiled cage, induced lordosis in approximately two-thirds of the females tested. When females were physically exposed to a male for 18 hr and tested 6 hr later, 70% showed lordosis. However, when females receiving either 1 or 18 hr of male contact were removed from the presence of the male and placed in a clean cage for 24 hr, only 29-37% of the females subsequently showed lordosis. These results suggest that direct physical contact with the male or chemical stimuli from the male may be necessary to induce and maintain behavioral estrus in female prairie voles.
