一些理论家提出，性类固醇睾酮在发育的关键时期作用于胎儿大脑，影响大脑的侧化（N。Geschwind & A. M. Galaburda，1987; M.海因斯公司Shipley，1984; S. F. Witelson，1991年）。在本研究中，产前睾酮水平之间的关系进行了检查，在第二个三个月的羊水和偏侧的语言，情感和利手在10岁。出生前睾丸激素水平较高的女孩更倾向于右撇子，左半球的语言表达能力也更强。出生前睾酮水平较高的男孩，右半球的情感识别能力较强。这一结果模式与Witelson（1991）的主张最为一致，即产前睾酮导致功能更大的偏侧化。
Several theorists have proposed that the sex steroid testosterone acts on the fetal brain during a critical period of development to influence cerebral lateralization (N. Geschwind & A. M. Galaburda, 1987; M. Hines & C. Shipley, 1984; S. F. Witelson, 1991). In the present study, relations were examined between prenatal testosterone levels in 2nd trimester amniotic fluid and lateralization of speech, affect, and handedness at age 10. Girls with higher prenatal testosterone levels were more strongly right-handed and had stronger left-hemisphere speech representation. Boys with higher prenatal testosterone levels had stronger right-hemisphere specialization for the recognition of emotion. This pattern of results is most consistent with Witelson's (1991) claim that prenatal testosterone leads to greater lateralization of function.
