The role of hormonal and experiential variables in mediating the gradual increase of receptivity occurring during weekly tests was evaluated in adult ovariectomized females. Hormone treatment consisted of estradiol benzoate (EB) injection followed by progesterone (P), 20alpha-hydroxyprogesterone (20alpha-OHP), methysergide maleate (Me), or oil during weekly mating tests. The experiential conditions were vaginal stimulation, mounts only, or no interaction with males. There was a gradual increase in receptivity in all groups even en the one receiving oil. Progressive facilitation occurred even when no interaction with the male was permitted. Interchanging the synergists on the sixth and seventh tests was not detrimental to the display of receptivity attained with synergists given previously. Thus, we concluded that successive injections of EB rather than synergists or experience mediate this increase in receptivity.
在成年去卵巢雌性动物中，评估了激素和经验变量在介导每周测试期间接受性逐渐增加中的作用。激素处理包括在每周交配测试期间注射苯甲酸雌二醇（EB），随后注射孕酮（P）、20α-羟基孕酮（20α-OHP）、马来酸麦角新碱（Me）或油。经验条件为阴道刺激、仅进行爬跨或不与雄性互动。即使在接受油注射的组中，所有组的接受性也都逐渐增加。即使不允许与雄性互动，也会出现渐进性促进作用。在第六次和第七次测试中交换增效剂对先前给予增效剂所达到的接受性表现并无不利影响。因此，我们得出结论，连续注射EB而非增效剂或经验介导了这种接受性的增加。
