The relationship between serum testosterone level and hand performance was studied in right-handed young adults without familial sinistrality. Hand performance was measured by a dot-filling task, which was found to be associated with serum testosterone depending upon sex. In women, the right- and left-hand performance was found to be negatively linearly related to testosterone; there was no significant correlation between the right- minus left-hand performance and testosterone. In men, right- and left-hand performance were found to be directly and inversely related to testosterone, respectively. This pattern exhibited some variations depending on eye and foot preferences. The difference in performance between hands was found to be positively linearly related to serum testosterone levels in men.
在没有家族性左利手的右利手年轻成年人中，研究了血清睾酮水平与手部表现之间的关系。通过点填充任务来测量手部表现，结果发现根据性别不同，手部表现与血清睾酮有关。在女性中，右手和左手的表现与睾酮呈负线性相关；右手与左手表现之差与睾酮之间无显著相关性。在男性中，右手和左手的表现分别与睾酮呈正相关和负相关。这种模式根据眼睛和脚的偏好表现出一些差异。男性双手表现的差异与血清睾酮水平呈正线性相关。
