通过对7只个体恒河猴、其他研究者先前研究的30只个体恒河猴的纵向生长研究以及对50年来报告的圈养恒河猴青春期类似观察结果的回顾，确定了正常未处理恒河猴青春期（首次会阴肿胀和月经初潮）时年龄、体重和体重增加之间的关系。有证据表明，恒河猴的青春期年龄有提前的长期趋势。青春期通常与青春期体重突增的开始相一致，并且总是在青春期体重增加的最大速率之前出现。虽然本研究中青春期的平均体重与先前的研究一致，但平均青春期年龄各不相同，这表明在不同的青春期年龄，临界“人口统计学体重”是恒定的。然而，对来自三项独立研究的37只性成熟恒河猴的检查显示，青春期的年龄和体重呈正相关。这些数据表明，在啮齿动物和家畜中发现的青春期年龄-体重分布的正相关也可能发生在高等灵长类动物中。一个主要的物种区别人类从一般哺乳动物青春期的年龄-体重模式，发现在恒河猴，提出了理论问题的作用“临界体重”在触发青春期。
The relationship between age, body weight and weight gain at puberty (first perineal turgescence and menarche) in the normal untreated rhesus monkey was determined from a longitudinal growth study of seven individual rhesus, 30 individual rhesus previously studied by other investigators and a review of 50 years of reported similar observations on captive rhesus at puberty. There was evidence of a secular trend towards an earlier age of puberty in the rhesus. Puberty was found to be generally coincident with the onset of the adolescent weight spurt and is invariably present before the maximum rate of pubertal weight gain. Although the average weight at puberty in the present study was consistent with prior studies, average pubertal age varied, suggesting a constant critical “demographic weight” at varying ages of puberty. Nevertheless, examination of 37 individual sexually mature rhesus from three separate studies showed age and weight at puberty were positively correlated. These data suggest that positive correlation in the pubertal age-weight distributions found in rodents and domestic animals may also occur in higher primates. A major species difference distinguishing the human from a general mammalian pubertal age-weight pattern, found in the rhesus, raises theoretical questions regarding the role “critical body weight” plays in triggering puberty.
