Menstrual patterns and progesterone levels were monitored for 5 years from a cohort of 28 female vervet monkeys that were individually caged indoors. Three distinct cycle types (short, normal, and prolonged) were defined according to cycle length. Mean length of the normal cycle (32.5 days) and menses duration (4.8 days) are in agreement with previous reports. Prolonged cycles (> 50 days) contributed 20% of the total, with a decreased incidence during the natural peak breeding period. Weekly progesterone measurements indicated that many prolonged cycles were associated with an extended luteal phase, while others were probably due to lack of ovulation. From these data it would appear that the vervet monkey, although not strongly seasonal, does favor a particular time of year for breeding in a colony housed indoors.
对28只单独饲养在室内笼子里的雌性绿猴进行了为期5年的月经模式和孕酮水平监测。根据周期长度定义了三种不同的周期类型（短周期、正常周期和长周期）。正常周期的平均长度（32.5天）和月经期持续时间（4.8天）与先前的报告一致。长周期（>50天）占总数的20%，在自然繁殖高峰期发病率降低。每周进行的孕酮测量表明，许多长周期与黄体期延长有关，而其他长周期可能是由于未排卵。从这些数据来看，绿猴虽然季节性不强，但在室内饲养的群体中确实倾向于在一年中的特定时间进行繁殖。
