Reproductive Ecology of Males in Turkana, Kenya

本提案的主要目的是调查 环境对男性生殖功能的影响 肯尼亚的图尔卡纳。 调查人员进行了模范的 图尔卡纳妇女生殖生态学研究和 建议的研究将扩大他们的研究。 图尔卡纳人分为定居和游牧两个群体， 饮食和活动模式不同。 此外，强 食物供应的季节性也导致饮食的变化。 的 研究者将使用血液和尿液样本， 睾酮和促性腺激素以及其他 生理功能和身体组成的指标。 从 先前的研究表明，生态因素强烈影响 女性生殖生物学 目前的研究将是 首先探讨生态在男性生殖功能中的作用。

The primary objective of this proposal is to investigate environmental influences on male reproductive functioning among the Turkana of Kenya. The investigators have conducted exemplary research on the reproductive ecology of Turkana women and the proposed research will extend their studies. The Turkana are divided into settled and nomadic groups which differ in diet and activity patterns. Additionally, strong seasonality in food supply leads to dietary variation as well. The investigators will utilize blood and urine samples to obtain profiles of testosterone and gonadotropins as well as other indicators of physiological functioning and body composition. From prior studies it is known that ecological factors strongly affect female reproductive biology. The current study will be one of the first to explore the role of ecology in male reproductive function.
