研究了性行为衰退10年以上的老年雄性恒河猴（Macaca mulatta）。相同的卵巢切除女性，年龄与男性（约20岁）相当，在10年期间担任性伴侣。在第一个实验中，年长的雄性与不熟悉的雌性配对，以确定改变性伴侣是否会扭转观察到的性能下降。不熟悉的女性，也是相同的年龄的男性，卵巢切除和治疗前配对雌二醇，因为是熟悉的女性。虽然雄性接触不熟悉的雌性比接触熟悉的雌性更频繁，但在性活动方面没有其他差异。两组雌性在对待雄性的行为上没有区别。男性与熟悉和不熟悉的女性的低水平的性表现可能是由于与女性的高龄相关的性主动性和反应性降低的结果，因此进行了第二个实验来测试这种可能性。年长的雄性与两组不同的陌生的、完整的、骑自行车的雌性配对。一组是年轻人（约4岁），另一组是老年人（约20岁）。雄性对年轻和年老雌性的性反应是相同的。两组雌性在对待雄性的行为上没有区别。
Old male rhesus monkeys(Macaca mulatta)whose sexual behavior had declined over a 10-year period were studied. The same ovariectomized females, comparable in age to the males (about 20 years old), served as sexual partners during the 10 years. In the first experiment the old males were paired with unfamiliar females to determine whether changing sexual partners would reverse the decline in performance that had been observed. The unfamiliar females, also about the same age as the males, were ovariectomized and treated with estradiol before pairing, as were the familiar females. Although the males contacted the unfamiliar females more often than they contacted the familiar females, there were no other differences in sexual activity. The two groups of females did not differ in their behavior toward the males. The low level of sexual performance by the males with both familiar and unfamiliar females could have been the result of decreased sexual initiative and responsiveness associated with the advanced age of the females, so a second experiment was undertaken to test this possibility. The old males were paired with two different groups of unfamiliar, intact, cycling females. One group was young (about 4 years old), the other old (about 20 years). The sexual responses of the males to both young and old females were the same. The two groups of females did not differ in their behavior toward the males.
