The-long term objectives of this research program are to identify those factors that cause or are associated with the decline in sexual activity that accompanies old age. Our research is focused on the decline in sexual behavior and accompanying changes in the hormonal milieu of aging rhesus macaques for what that research may contribute to an understanding of the decline in sexual behavior of aging primates, including man. In a society whose population is steadily growing older, the need for such research grows in importance. Our research is experimental, interdisciplinary, and includes the quantitative assessment of behavioral endpoints following manipulation of environmental, and hormonal variables. Our specific aims are to determine: (1) the extent to which manipulation of environmental conditions such as the social situation and sexual partner can modify sexual performance in old males and hence permit us to assess the degree to which the decline in sexual performance is dependent upon psychological variables (2) the extent to which the decline in sexual performance is related to the competency of the brain- pituitary-gonadal system in old males as that system governs the hormonal environment modulating sexual performance and reproductive function (3) the specific changes in sexual behavior that occur over time with associated changes in serum hormone levels, and if and at what level sexual behavior reaches an asymptote in very old age. Old rhesus males (18-28 years old) whose sexual performance and hormone levels we have monitored since 1970 provide us with a unique opportunity to determine the physiological and psychological correlates of sexual behavior in an aging population of nonhuman primates.

该研究计划的长期目标是确定 那些导致或与下降有关的因素 伴随老年的性活动。 我们的研究重点 性行为的减少以及随之而来的性变化 衰老恒河猴的荷尔蒙环境有何研究意义 可能有助于了解性能力下降 包括人类在内的衰老灵长类动物的行为。 在一个社会中， 人口不断老龄化，需要进行此类研究 重要性日益增强。 我们的研究是实验性的， 跨学科，包括定量评估 操纵环境后的行为终点，以及 荷尔蒙变量。 我们的具体目标是确定：（1） 操纵环境条件的程度，例如 社会环境和性伴侣可以改变性行为 老年男性的表现，因此允许我们评估 性能力下降的程度取决于 心理变量 (2) 下降的程度 性能力与大脑的能力有关 老年男性的垂体-性腺系统，因为该系统控制着 调节性能力的荷尔蒙环境和 生殖功能（3）性行为的具体变化 随着时间的推移，血清激素发生相关变化 水平，以及性行为是否以及在什么水平上达到 老年时渐近。 雄性老年恒河猴（18-28岁） 我们监测了其性表现和激素水平 自 1970 年以来为我们提供了一个独特的机会来确定 性行为的生理和心理相关性 非人类灵长类动物的人口老龄化。
