At and near Agra, in Uttar Pradesh, India, R. h. hardwickei had a strictly defined annual reproductive cycle. Although many females were inseminated during late February to mid April, ovulation was not recorded until 11 March. Progressively more females ovulated and conceived during the following weeks until the end of April and released one ovum from either of the ovaries with nearly equal frequency. A single conceptus was carried in the ipsilateral uterine cornu during each cycle. The gestation period was 95-100 days. Births occurred between the second week of June and the end of July. Lactation lasted at least 20 days. Females attained sexual maturity at an age of 8.5-9.0 months. Males took at least 16-17 months to attain sexual maturity. Females were segregated during lactation; during the rest of the year, males and females lived together.
在印度北方邦阿格拉及其附近地区，哈氏叶猴有着严格定义的年度繁殖周期。尽管许多雌性在2月下旬至4月中旬接受了受精，但直到3月11日才记录到排卵。在接下来的几周内，越来越多的雌性排卵并受孕，直至4月底，且左右卵巢排卵的频率几乎相等。每个周期中，单个受精卵会着床于同侧子宫角。妊娠期为95至100天。分娩发生在6月的第二周和7月底之间。哺乳期至少持续20天。雌性在8.5至9.0个月大时达到性成熟。雄性至少需要16至17个月才能达到性成熟。雌性在哺乳期会分开；一年中的其他时间，雄性和雌性生活在一起。
