雄性恒河猴生殖功能的季节性变化

Seasonal Variation of Reproductive Functions in Male Rhesus Monkey

采用随机抽样法和放射免疫测定法 ,分析了雄性恒河猴在不同季节的体重、睾丸容积、射精量、促卵泡刺激素(FSH)、促黄体生成素 (L H)和睾酮的变化情况。试验结果显示 ,雄性恒河猴的体重、睾丸容积和射精量的变化受季节因素的影响。在非生殖季节 ,雄性恒河猴的 FSH、L H和睾酮分泌水平明显偏低。在生殖季节 ,雄性恒河猴的 FSH、L H和睾酮分泌水平显著升高。

Seasonal biological variation in the body weights,testicular volumes,ejaculates and hormones was assayed in male rhesus monkey.The reproductive hormone levels were measured with radioimmune technique.The results showed that:(1)There were the periodic changes in sexual characteristics,body weights,testicular volumes and ejaculates of all male rhesus monkeys between the breeding season and the nonbreeding season.(2)The reproductive hormone increased in the breeding period and decreased in the nonbreeding season.The seasonal biological variations influence the reproductive functions of male rhesus monkey.
