Relative finger lengths, especially the second-to-fourth finger length ratio, have been proposed as useful markers for prenatal testosterone action. This claim partly depends on an association of relative finger lengths in adults with related sex differences in children and infants. This paper reports the results of a study using serial radiographs to test for both sex differences in the fingers of infants and children and for a relationship between sex differences in the children and infant finger and adult finger length ratios. This is the first study using long-term serial data to evaluate the validity of finger length ratios as markers. We found not only that sex differences in finger length ratios arise prior to puberty, but that sex differences in the fingers of children are highly correlated with adult finger length ratios. Our results strongly encourage the further use of finger length ratios as markers of perinatal testosterone action.
相对手指长度，尤其是食指与无名指长度之比，已被认为是产前睾酮作用的有用标志。这一说法部分取决于成年人的相对手指长度与儿童和婴儿相关性别差异之间的关联。本文报告了一项研究结果，该研究使用连续X线照片来检测婴儿和儿童手指的性别差异，以及儿童和婴儿手指的性别差异与成人手指长度之比之间的关系。这是第一项使用长期连续数据来评估手指长度比作为标志有效性的研究。我们不仅发现手指长度比的性别差异在青春期之前就已出现，而且儿童手指的性别差异与成人手指长度比高度相关。我们的结果有力地鼓励进一步将手指长度比用作围产期睾酮作用的标志。
