生殖老化的速度一直是相当大的兴趣，特别是在现代妇女的长期postreproductive时期。在这里，我们使用的数据从一个野生狒狒种群的37年的纵向研究中的性别，将生殖衰老的生活史背景下，这个物种，灵长类动物的相对人类进化在相同的萨凡纳栖息地，因为人类没有。我们研究了生殖老化的模式和速度，包括男女的出生率和生殖激素，并将生殖老化与其他几个特征的年龄相关变化进行了比较。雌性狒狒的生殖衰老比雄性晚。女性相对于男性的延迟衰老也存在于其他几个特征中，如优势地位和身体状况，但不存在于磨牙磨损或糖皮质激素分布中。生存、健康和幸福是形态、生理和行为特征中风险因素的产物，这些风险因素在衰老速度和对社会或生态条件的依赖性方面有所不同;有些人对环境的差异非常敏感，而另一些人则不那么敏感。
The pace of reproductive aging has been of considerable interest, especially in regard to the long postreproductive period in modern women. Here we use data for both sexes from a 37-year longitudinal study of a wild baboon population to place reproductive aging within a life history context for this species, a primate relative of humans that evolved in the same savannah habitat as humans did. We examine the patterns and pace of reproductive aging, including birth rates and reproductive hormones for both sexes, and compare reproductive aging to age-related changes in several other traits. Reproductive senescence occurs later in baboon females than males. Delayed senescence in females relative to males is also found in several other traits, such as dominance status and body condition, but not in molar wear or glucocorticoid profiles. Survival, health, and well-being are the product of risk factors in morphological, physiological, and behavioral traits that differ in rate of senescence and in dependence on social or ecological conditions; some will be very sensitive to differences in circumstances and others less so.
