Reproductive cycles of female talapoins living in caged breeding groups were followed over 7 years, using visible changes of the perineum. Changes in the perineum during the extended adolescence of this species are described. There was a clearly defined breeding season, although its onset was not so abrupt as in the wild. During the summer months females show very small perineal swellings or none at all. Even during the breeding season all stages of the follicular phase of cycles are highly variable. Completed menstrual cycles are relatively rare since talapoins are highly fertile; they may be somewhat shorter than fertile cycles. Cyclical activity is modifiable by social stimuli, and it is suggested that differences in synchrony of breeding between wild and captive populations might be due both to indequate climate cues and to a lower level of social stimulation in captivity. The concept of the menstrual cycle had limited value in predicting reproductive activity in this highly fertile seasonal breeder.
通过观察会阴部的明显变化，对生活在笼养繁殖群体中的雌性侏长尾猴的生殖周期进行了长达7年的跟踪研究。描述了该物种在延长的青春期期间会阴部的变化。虽然繁殖季节有明确界定，但其开始不像在野外那样突然。在夏季，雌性的会阴部肿胀非常小或根本没有肿胀。即使在繁殖季节，周期中卵泡期的各个阶段也高度可变。由于侏长尾猴繁殖力很强，完整的月经周期相对较少；它们可能比可育周期稍短。周期性活动可被社会刺激所改变，有人认为野生种群和圈养种群繁殖同步性的差异可能是由于气候线索不足以及圈养环境中社会刺激水平较低所致。月经周期的概念在预测这种繁殖力很强的季节性繁殖者的生殖活动方面价值有限。
