The relationship between serum testosterone level and the degree of hand preference was studied in right-handed young adults. Hand preference was assessed by the Edinburgh Handedness Inventory. Serum testosterone level was determined using tritium-marked-radioimmunoassay. There was no significant correlation between these variables in males without FS. In males with FS and in females with and without FS, the serum testosterone levels were found to be negatively linearly correlated with the degree of the right-hand preference. Similar results were obtained with respect to foot and eye preferences. It was concluded that not only prenatal testosterone but adult testosterone also may exert a life long influence on cerebral lateralization; this effect seems to be much more pronounced in the female than male brain, which may exert a female-like pattern under genetic control.
在右利手的年轻成年人中研究了血清睾酮水平与利手程度之间的关系。通过爱丁堡利手量表评估利手情况。使用氚标记放射免疫分析法测定血清睾酮水平。在没有FS的男性中，这些变量之间没有显著相关性。在有FS的男性以及有和没有FS的女性中，发现血清睾酮水平与右利手程度呈负线性相关。关于足利手和眼利手也获得了类似结果。得出的结论是，不仅产前睾酮，而且成年期睾酮也可能对大脑偏侧化产生终生影响；这种影响在女性大脑中似乎比男性大脑中更为明显，在基因控制下可能呈现出类似女性的模式。
