背景：性别差异存在于人类社会行为的某些领域。在动物中，胎儿睾丸激素（fT）在组织大脑和后来的社会行为中起着核心作用。fT还与人类的语言发展、目光接触和空间能力有关。方法：对58例儿童（男35例，女23例）在4岁时进行羊水fT分析。他们的母亲完成了儿童沟通检查表，这是一份评估语言、社会关系质量和限制兴趣的问卷。结果：考虑到性别差异，fT与社会关系质量呈负相关。fT还与男孩的兴趣限制呈正相关。结论：这些发现暗示fT在社会发展和注意力集中方面都有影响。它们也可能对理解自闭症的性别比例有启示。
Background: Sex-differences exist in some areas of human social behaviour. In animals, foetal testosterone (fT) plays a central role in organising the brain and in later social behaviour. fT has also been implicated in language development, eye-contact, and spatial ability in humans. Methods: Fifty-eight children (35 male and 23 female), whose fT was analysed in amniotic fluid, were followed up at age 4. Their mothers completed the Children's Communication Checklist, a questionnaire assessing language, quality of social relationships and restricted interests. Results: fT was negatively correlated to quality of social relationships, taking sex-differences into account. fT was also positively correlated with restricted interests in boys. Conclusions: These findings implicate fT in both social development and attentional focus. They may also have implications for understanding the sex ratio in autism.
