季节性变化对雌性恒河猴生殖功能的影响

目的　研究季节性变化对雌性恒河猴生殖功能的影响。方法　采用随机抽样法和放射免疫测定法 ,分析了不同时期雌性恒河猴性皮肤变化、月经周期和生殖激素变化的特点。结果　 ( 1)性征的季节性变化 :在生殖季节雌性恒河猴几乎都出现性皮肤反应 ,出现比较规则月经周期 ,在非生殖季节只有部分雌性恒河猴出现性皮肤反应 ,月经周期不规则 ,行经频率低 ,有的出现长时间的闭经 ;( 2 )生殖激素的季节性变化 :在生殖季节促性腺激素和性类固醇激素的分泌水平都出现周期性的变化 ,而非生殖季节促性腺激素和性类固醇激素的分泌水平没有显著的差异。结论　雌性恒河猴性皮肤变化、月经周期和生殖激素存在明显的季节性差异 ,这种差异导致了雌性恒河猴生殖功能的季节性变化

Seasonal Variation Influences on Reproductive Functions in Female Rhesus Monkey

Objective To study the seasonal variation influences on reproductive functions in female rhesus monkey. Method\ Seasonal biological variations in skins,menstrual cycle,level of hormones were assasyed by random sampling of statistics method and radioimmune technique.Results\ 1.The periodic changes in sexual characteristics were demonstrated,including the sexual skins and normal menstrual cycles of all female rhesus monkeys during the breeding season.During the non\|breeding season some female rhesus monkeys displayed the sexual skins and abnormal menstrual cycles,a few female rhesus monkeys showed no menstrual cycles for a longer time.2.Gonadotropin and steroidogensis displayed significant cyclical secretion in the breeding period,while no significant cyclical secretion in the non\|breeding season.Conclusion\ It is suggested that female rhesus monkeys show remarkable sexual skins,menstrual cycles and hormones change between the breeding and non\|breeding seasons,which could lead to different reproductive functions of female rhesus monkey.
