Social subordination is associated with impaired reproductive success among female macaques living in natural or "semi-natural" environments. We studied the relationship between social status and ovarian function in female cynomolgus macaques living in socially stable single-male harem groups or in groups of like composition in which social instability was induced by the frequent redistribution of female group members. Compared to socially dominant females, socially subordinate females had fewer ovulatory menstrual cycles, more cycles with deficient luteal phase plasma progesterone concentrations, increased adrenal weights and increased heart weights. Social instability influenced none of these variables. In fact, females living in the situations of induced social instability had higher luteal phase plasma progesterone concentrations; this may be the result of frequent exposure to novel males. The results indicate that impaired reproductive success observed in socially subordinate female macaques may be related, at least in part, to changes in ovarian endocrine and ovulatory function.
在生活于自然或“半自然”环境中的雌性猕猴中，社会从属地位与繁殖成功率受损有关。我们研究了生活在社会稳定的单雄后宫群体中或组成相似但因雌性群体成员频繁重新分配而导致社会不稳定的群体中的食蟹猕猴雌性个体的社会地位与卵巢功能之间的关系。与社会占主导地位的雌性相比，社会从属地位的雌性排卵月经周期较少，黄体期血浆孕酮浓度不足的周期更多，肾上腺重量增加，心脏重量增加。社会不稳定对这些变量均无影响。事实上，生活在人为造成社会不稳定环境中的雌性黄体期血浆孕酮浓度更高；这可能是频繁接触陌生雄性的结果。结果表明，在社会从属地位的雌性猕猴中观察到的繁殖成功率受损可能至少部分与卵巢内分泌和排卵功能的变化有关。
