Comparative studies of reproductive characteristics were carried out on a colony of Macaca fascicularis and M. arctoides. Seasonal differences were not significant between species, and conceptions occurred throughout the year. The occurrence of short cycles ('luteal phase defect') was found in 2.9% of all M. fascicularis cycles and 1.5% of all M. arctoides cycles. Long cycles (40-50 days) were found in 4.0% of all M. fascicularis cycles and 3.5% of all M. arctoides cycles. Gestation lengths averaged 172.4 and 165.3 days, respectively, for M. arctoides and M. fascicularis. Ovulation in M. fascicularis occurred at a day of ovulation/cycle length ratio of 0.48 +/- 0.08 compared with 0.48 +/- 0.09 for M. mulatta data previously published.
对一群食蟹猴和熊猴的生殖特征进行了比较研究。两种猴之间的季节性差异不显著，全年均可受孕。在所有食蟹猴的周期中，有2.9%出现短周期（“黄体期缺陷”），在所有熊猴的周期中，这一比例为1.5%。在所有食蟹猴的周期中，有4.0%出现长周期（40 - 50天），在所有熊猴的周期中，这一比例为3.5%。熊猴和食蟹猴的妊娠期平均分别为172.4天和165.3天。食蟹猴的排卵日与周期长度之比为0.48±0.08，而此前发表的恒河猴的数据为0.48±0.09。
