Differences in responsiveness of precopulatory patterns to estradiol were investigated in the female Mongolian gerbil. Administration of five daily injections of 6 micrograms estradiol benzoate (EB) to ovariectomized females demonstrated that the precopulatory patterns differ in their responsiveness to EB. Estradiol benzoate shortened the latency to the first significant increase in frequency above post-ovariectomy levels for a group of precopulatory patterns (investigation of male's anogenital area, allogrooming and ventral gland marking) in comparison with a second group (approaching, leaving, investigation of the male's head, sand rolling, the present and piloerection postures). One component of precopulatory behavior (foot stomping) was not affected by EB. We suggest that the first group of more estrogen-sensitive patterns increases rapidly during early estrus as plasma estradiol-17 beta (E2) rises, whereas the second group shows peak levels later in estrus following the rise in plasma progesterone. We conclude that separable hormonal mechanisms may govern component precopulatory patterns.
在雌性蒙古沙鼠中研究了交配前行为模式对雌二醇反应性的差异。对去卵巢的雌性沙鼠每日注射5次6微克苯甲酸雌二醇（EB），结果表明，交配前行为模式对EB的反应性存在差异。与第二组行为模式（接近、离开、检查雄性头部、翻滚沙子、当前姿势和竖毛姿势）相比，苯甲酸雌二醇缩短了一组交配前行为模式（检查雄性肛门生殖器区域、相互梳理毛发和腹侧腺体标记）在卵巢切除术后频率首次显著高于术后水平的潜伏期。交配前行为的一个组成部分（跺脚）不受EB影响。我们认为，随着血浆雌二醇-17β（E2）水平在发情早期迅速上升，第一组对雌激素更敏感的行为模式迅速增加，而第二组行为模式在发情后期血浆孕酮水平上升后达到峰值。我们得出结论，不同的激素机制可能控制着交配前行为的各个组成部分。
