在与雄性大鼠的性接触过程中，雌性大鼠会表现出接受（脊柱前凸）和接受（跳跃，飞镖和耳朵摆动）行为。此外，如果交配发生在雌性大鼠可以接近和离开雄性大鼠的环境中，她将控制接受坐骑、插入和射精的时间。雌性大鼠的这种时间模式被称为节奏交配行为。本实验比较了大鼠在完整的发情前期和卵巢切除期的起搏交配行为，在此期间，它们被给予苯甲酸雌二醇（10 μg/只大鼠）和孕酮（0.5 mg/只大鼠）。虽然在两个阶段没有观察到性感受性的差异，但发现节奏交配行为的模式不同。具体而言，雌性大鼠表现出显着更长的接触返回lavelian激素治疗时，比完整的。
During a sexual encounter with a male rat, a female rat will display both receptive (lordosis) and proceptive (hopping, darting, and ear-wiggling) behaviors. Additionally, if mating occurs in an environment where the female rat may approach and withdraw from the male rat, she will control the timing of the receipt of mounts, intromissions, and ejaculations. This temporal patterning by the female rat is known as paced mating behavior. The present experiment compared paced mating behavior in rats during an intact, proestrous phase and an ovariectomized phase, during which they were treated with estradiol benzoate (10 μg per rat) and progesterone (0.5 mg per rat). Though no differences in sexual receptivity were observed across the two phases, patterns of paced mating behavior were found to differ. Specifically, female rats exhibited significantly longer contact–return latencies when hormone treated than when intact.
