The studies on fecal steroid metabolites published with free-living primates are limited mainly by the difficulty in obtaining samples.
A radioimmunoassay was used to measure the fecal steroid concentrations in Alouatta belzebul in the National Forest of Tapirape-Aquiri in Brazil.
Androgens were significantly higher for the adult males from the Area of Influence (AI-I group) when compared to those from the Control Area (CA group) (P < 0.05). Progestin and estrogen concentrations were higher in the females from the CA group than in those from the AI-I for both the adult females and females with offspring; however, P < 0.05 was only observed in the concentrations of fecal progestins from the adult females. The physiological differences between the AI-I and CA groups suggest that the cause was a sum of factors, such as an exposure to sound waves, feeding habits, daily activity patterns, and the habituation of the animals.
关于自由生活的灵长类动物粪便类固醇代谢物的研究主要受限于获取样本的困难。
采用放射免疫分析法测定巴西塔皮拉佩 - 阿基里国家森林中黑吼猴粪便中的类固醇浓度。
与来自对照区（CA组）的成年雄性相比，来自影响区（AI - I组）的成年雄性雄激素水平显著更高（P < 0.05）。对于成年雌性和有后代的雌性，CA组雌性的孕激素和雌激素浓度高于AI - I组雌性；然而，仅在成年雌性粪便孕激素浓度中观察到P < 0.05。AI - I组和CA组之间的生理差异表明，其原因是多种因素的综合作用，如接触声波、饮食习惯、日常活动模式以及动物的习性。
