The behavioral responses of the female golden hamster to a sexually experienced male were analyzed as a function of the stage of the female's estrous cycle. Exogenous estradiol or estradiol followed by progesterone was given to ovariectomized females to determine the role of these hormones in the regulation of cyclic changes in the female's response to the male. Females were paired on a daily basis with sexually active males for 10 min, and behavioral interactions were recorded. Significantly more fighting occurred during early diestrus than later in the cycle. During the 24 hr preceding sexual receptivity, fighting was infrequent. BY 8 HR PRIOR TO THE ONSET OF SEXUAL RECEPTIVITY, 86% OF THE POPULATION EXHIBITED A BEHAVIOR RESEMBLING THE ONSET OF LORDOSIS WITHOUT IMMOBILIZATION (PRELORDOSIS). Following ovariectomy fighting was at a high level (80%--90%). Estradiol replacement, over a 28-day test period, resulted in a significant decrease in aggression and a significant increase in the display of the prelordotic response without inducing lordosis. Initially, the treatment with progesterone following 7 days of estradiol treatment caused the female to display lordosis. After 24 hr a significant increase in aggression, which continued as long as progesterone was present, was observed. After removal of progesterone a significant decrease in aggression occurred. Thus, estradiol causes the female to become tolerant of the male's approach, the female exhibiting prelordosis in response to the male's investigation. Estradiol and progesterone are necessary for normal sexual receptivity; however, after 24 hr, estrogen-progesterone-treated females become agonistic to the male.
对雌性金黄地鼠针对有性经验雄性的行为反应进行了分析，分析内容为雌性发情周期阶段的函数。给卵巢切除的雌性注射外源性雌二醇或先注射雌二醇再注射孕酮，以确定这些激素在调节雌性对雄性反应的周期性变化中的作用。雌性每天与性活跃的雄性配对10分钟，并记录行为互动情况。在动情间期早期发生的打斗明显多于发情周期后期。在性接受前的24小时内，打斗很少发生。在性接受开始前8小时，86%的群体表现出一种类似于脊柱前凸起始但无强直静止的行为（前脊柱前凸）。卵巢切除后打斗处于高水平（80% - 90%）。在28天的测试期内补充雌二醇导致攻击性显著降低，前脊柱前凸反应的表现显著增加，但未诱发脊柱前凸。最初，在雌二醇治疗7天后用孕酮治疗会使雌性表现出脊柱前凸。24小时后，观察到攻击性显著增加，只要有孕酮存在，这种增加就会持续。去除孕酮后，攻击性显著降低。因此，雌二醇使雌性对雄性的接近变得耐受，雌性在雄性进行探究时表现出前脊柱前凸。雌二醇和孕酮对于正常的性接受是必要的；然而，在24小时后，经雌激素 - 孕酮处理的雌性会对雄性产生攻击性。
