Effects of male partners upon the expression of female proceptivity were examined in two experiments using 16 ovariectomized marmosets. Experiment 1 showed that the female's proceptive tongue-flicking display (PTF) is triggered specifically by eye contact with the male. Stimulation of PTF by administration of estradiol-17 beta (E2) to ovariectomized females depends in part upon the male's responsiveness to female displays, such as "staring" and "freezing," which may serve to attract his attention and to establish eye contact. Experiment 2 provided evidence that females' proceptivity decreases if their male partners are lesioned in the preoptic area/anterior hypothalamus. Such males are sexually hypoactive and less responsive to the females' visual displays. However, E2 still activates PTF if females succeed in initiating eye contact with males. Results indicate that variability in effects of E2 upon proceptivity in marmosets may be influenced by subtle aspects of facial communication between the sexes as well as by individual differences in hormonal sensitivity. Copulatory activity in males is not essential for E2 to exert its stimulatory action upon proceptivity in female marmosets.
在两项使用16只卵巢切除的狨猴的实验中，研究了雄性伴侣对雌性接受性表达的影响。实验1表明，雌性的接受性舔舌展示（PTF）是由与雄性的眼神接触特异性触发的。对卵巢切除的雌性施用雌二醇-17β（E2）刺激PTF，部分取决于雄性对雌性展示（如“凝视”和“静止不动”）的反应，这些展示可能有助于吸引他的注意并建立眼神接触。实验2提供的证据表明，如果雌性的雄性伴侣在视前区/下丘脑前部受损，雌性的接受性会降低。这种雄性的性活动低下，对雌性的视觉展示反应较小。然而，如果雌性成功与雄性建立眼神接触，E2仍然会激活PTF。结果表明，E2对狨猴接受性影响的变异性可能受到两性之间面部交流的细微方面以及激素敏感性个体差异的影响。雄性的交配活动对于E2对雌性狨猴接受性发挥刺激作用并非必不可少。
