Physiological changes around the time of puberty were studied in a longitudinal manner in male and female stumptail macaques. In the male, testicular descent (mean age 3.3 years) is an early sign of puberty, which coincides with onset of the pubertal spurt in body weight and testis growth and precedes the pubertal rise in plasma testosterone. In the female no clear external signs of puberty have been found. Measurements of plasma progesterone yielded proof of first ovulation (mean age 3.7 years), a late sign of puberty in primates. This event coincided with a fall in the rate of body weight growth at the end of the pubertal growth spurt. Reproductive capacity of both males (first ejaculation) and females (first conception) appears to be reached around the 4th birthday.
对雄性和雌性短尾猕猴青春期前后的生理变化进行了纵向研究。在雄性中，睾丸下降（平均年龄3.3岁）是青春期的早期迹象，这与体重青春期突增和睾丸生长的开始同时发生，并先于血浆睾酮的青春期升高。在雌性中，尚未发现明显的青春期外部迹象。血浆孕酮的测量结果证实了首次排卵（平均年龄3.7岁），这是灵长类动物青春期的晚期迹象。这一事件与青春期生长突增末期体重增长速率的下降同时发生。雄性（首次射精）和雌性（首次受孕）的生殖能力似乎在4岁左右达到。
