唾液睾酮水平进行了测量，在人口的新大陆土著成年狩猎采集男性，以比较循环水平的自由未结合的生物活性类固醇与以前报道的波士顿和非西方男性。研究人群包括成年Aché狩猎采集男性（n=45）生活在巴拉圭东部。早晨和晚上唾液睾酮水平（TsalA.M.; TsalP.M.）在Aché人中，这一比例远低于西方人（波士顿人），甚至低于其他先前报道的非西方人群（Efe，Lese，尼泊尔人）。在Aché组中，没有观察到身高、体重或年龄与唾液睾酮水平之间的关联，尽管研究样本中老年男性（年龄>40岁）的代表性很差。然而，Aché TsalA.M.水平与BMI相关（r= 0.133，p =0.0725）。Aché值与其他人群的比较证实了成年男性睾酮水平存在显著的人群间差异。然而，男性睾酮的种群间差异并不像女性卵巢类固醇的差异那么大，这种差异也不太可能反映男性生育力的差异。然而，唾液睾酮水平的这种群体间变化可能在调节骨骼肌中的蛋白质代谢方面具有功能意义，从而影响生物体的总体能量预算。这表明，平均睾酮的相对抑制可能是适应条件下的慢性能量短缺。
Salivary testosterone levels were measured in a population of New World indigenous adult hunter-gatherer males in order to compare circulating levels of free unbound bioactive steroid with those previously reported among Boston and nonwestern males. The study population consisted of adult Aché hunter-gatherer males (n=45) living in eastern Paraguay. Morning and evening salivary testosterone levels (TsalA.M.; TsalP.M.) among the Aché were considerably lower than western values (Boston) and even lower than other previously reported nonwestern populations (Efe, Lese, Nepalese). No association was observed between height, weight, or age and salivary testosterone levels within the Aché group, although older men (ages>40) were poorly represented in the study sample. Nevertheless, a mild correlation was observed between Aché TsalA.M. levels and BMI (r=0.133,p=0.0725). Comparison of Aché values with those for other populations confirms the prevalence of significant interpopulational variation in testosterone levels among adult males. Interpopulational variation in male testosterone is not as great, however, as has been documented for ovarian steroids among females, nor is it likely that such variation reflects differences in male fecundity. Nevertheless, such interpopulational variation in salivary testosterone levels may have a functional significance in the regulation of protein anabolism in skeletal muscle, thereby affecting the overall energy budget of the organism. It is suggested that relative suppression of average testosterone may be adaptive under conditions of chronic energy shortage.
