在完整的骑行大鼠和去卵巢和去卵巢-去肾上腺激素刺激的大鼠身上，使用分隔的测试笼子来检查女性的性行为，在这个测试笼子里，雌性动物控制着与雄性动物发生性关系的时间。雌鼠在隔开的测试笼子中(有步调)或移除隔板(非步调)中插入9或10个，或单独暴露在测试笼子中，或使用阴道口罩在没有插入的坐骑上。完整的骑行(实验1)和去性腺激素刺激的(实验2)大鼠表现出类似的与雄性接触的模式：存在从雄性隔间返回的潜伏期随着前交性刺激强度的增加而增加(射精大于插入大于坐骑)。在发情前期的晚上，在第二次测试中，在17-24天后的第二次测试中，经历了有节奏或无节奏交配的骑行雌性没有表现出不同的起步行为。那些接受有节奏的性交刺激的人表现出比那些接受非有节奏刺激的人更短的发情持续时间。去卵巢和去卵巢-去肾上腺的有步调的大鼠连续给予三种剂量的苯甲酸雌二醇和黄体酮，没有表现出比没有起搏的大鼠或仅有起搏的大鼠更短的发情期。这些结果表明，对宫颈-阴道起搏刺激的卵巢输出可能有助于终止大鼠的发情。
Feminine sexual behavior was examined in intact cycling rats and ovariectomized and ovariectomized-adrenalectomized hormone-primed rats with the use of a partitioned test cage in which the female controlled the timing of sexual contacts with males. Females received 9 or 10 intromissions in the partitioned test cage (paced) or with the partition removed (nonpaced) or received solitary exposure to the test cage or to mounts without intromission with the use of vaginal masks. Intact cycling (Experiment 1) and gonadectomized hormone-primed (Experiment 2) rats displayed similar patterns of contact with males: Exists from and latencies to return to the male compartment increased as the intensity of the antecedent coital stimulation increased (ejaculations greater than intromissions greater than mounts). Cycling females given experience with paced or nonpaced mating on the evening of proestrus did not exhibit differences in pacing behavior on a second test 17-24 days later. Those receiving paced coital stimulation showed a shorter duration of estrus than did those receiving nonpaced stimulation. Ovariectomized and ovariectomized-adrenalectomized paced rats given three successive doses of estradiol benzoate in combination with progesterone did not show shorter periods of estrus than nonpaced or mounts-only rats. These results suggest that ovarian output in response to paced cervical-vaginal stimulation may contribute to the termination of estrus in the rat.
