圈养条件下黑猩猩月经、排卵和妊娠周期

排卵期和妊娠期与月经周期紧密相关，监测月经周期对圈养黑猩猩（Pan troglodytes）的繁殖有着重要意义。本研究对上海动物园饲养的8只雌性黑猩猩2002年以来的月经周期记录进行统计分析，并对2只成年雌性黑猩猩共60 d尿液中促黄体生成素进行检测。黑猩猩月经周期平均为（33.5 ± 5.3）d，经期平均为（1.6 ± 1.1）d，妊娠期平均为（226.9 ± 17.3）d，产单胎和双胎有极显著差异；促黄体生成素在发情高峰期出现了峰值。

Menstrual Cycle, Ovulation and Gestation in Chimpanzee (Pan troglodytes) in Captivity

Ovulation and gestation are closely related to menstrual cycle. It is important to monitor the menstrual cycle of chimpanzees (Pan troglodytes) in captivity. This study analyzed the menstrual cycle records of 8 females reared in Shanghai Zoo since 2002 to 2017, and the data were analyzed by SPSS22.0. The luteinizing hormone (LH) in the urine of 2 female chimpanzees in a 60-day period was tested by using radioimmunoassay. The results showed that the average menstrual cycle was 33.5 ± 5.3 days; the average period of menstruation was 1.6 ± 1.1 days (Table 2); the average gestation period was 226.9 ± 17.3 days, with significant difference between the single and twins; LH surge appeared in estrus peak (Fig. 2).
