Dermatoglyphic prints and salivary samples were taken on a sample of 39 adult males. A statistical relationship between dermatoglyphic asymmetry and adult testosterone levels as measured in saliva was examined for seven dermatoglyphic variables by means of correlation, regression, and analysis of covariance, controlling for age and stature when necessary. The first two types of analyses indicated a significant effect of testosterone level upon the asymmetry of three dermatoglyphic variables: a-b ridge count, palmar pattern intensity, and the combined pattern intensity of palm and digits. Analysis of covariance, which examined the effect of testosterone level as a categorical variable, while holding age or stature constant, demonstrated the asymmetry of five variables to be significantly affected by testosterone level: radial digital count, digital pattern intensity, palmar pattern intensity, total digital ridge count, and the combined palmar and digital intensity. Although there is as yet only associational evidence linking levels of prenatal and secondary testosterone, the results of the present study lend support to the hypothesis that prenatal testosterone levels may have a significant effect on the development of dermatoglyphics.
对39名成年男性的样本采集了皮纹印记和唾液样本。通过相关性、回归分析和协方差分析，在必要时控制年龄和身高，研究了七个皮纹变量的皮纹不对称性与唾液中测得的成年男性睾酮水平之间的统计关系。前两种分析表明，睾酮水平对三个皮纹变量的不对称性有显著影响：a - b嵴纹计数、手掌图案强度以及手掌和手指的综合图案强度。协方差分析将睾酮水平作为分类变量进行研究，同时保持年龄或身高不变，结果表明五个变量的不对称性受到睾酮水平的显著影响：桡侧指嵴计数、指图案强度、手掌图案强度、总指嵴计数以及手掌和手指的综合强度。尽管目前仅有关联证据将产前和青春期后的睾酮水平联系起来，但本研究结果支持了产前睾酮水平可能对皮纹发育有显著影响这一假设。
