Thirty-five live births were recorded over a 5-year period from three subspecies of the mitis (Sykes and blue) monkey (Cercopithecus mitis) maintained outdoors in single-male harem breeding groups. There was no indication of birth seasonality. Females of one subspecies, C. m. kolbi, were individually caged, and basic reproductive parameters were monitored. A menstrual cycle length of 31.9 ± 6.0 days was recorded, and there were a large number of irregular cycles. Within individuals, mean progesterone and estrogen concentrations during the luteal phase of the cycle ranged from 5.5 to 10.7 nmol/liter and from 542 to 829 pmol/liter, respectively. Attempts at timed matings were unsuccessful. It is concluded that the mitis monkey is slow to adapt reproductively to captivity and is, therefore, not especially well-suited for routine reproductive studies. However, it may prove valuable to elucidate some of the more complex factors controlling guenon reproduction.
在 5 年期间，从饲养在户外的单雄饲养群中的三种米蒂斯（塞克斯和蓝色）猴（Cercopithecus mitis）中记录了 35 例活产。没有出生季节性的迹象。一种亚种 C. m. kolbi 的雌性被单独关在笼子里，并监测基本的生殖参数。记录到的月经周期长度为 31.9±6.0 天，并且存在大量不规则周期。在个体内，周期黄体期的平均孕激素和雌激素浓度分别为 5.5 至 10.7 nmol/升和 542 至 829 pmol/升。定时交配的尝试没有成功。结论是，米蒂斯猴在生殖方面对圈养的适应速度较慢，因此不太适合常规的生殖研究。然而，它可能有助于阐明控制长尾猴繁殖的一些更复杂的因素。
