摘要：

Background: Ratios of digit lengths are studied intensively as markers of prenatal sex hormone levels. Aim: Study sexual dimorphism in ratios of metacarpals, which received less attention. Methods: We studied six metacarpal ratios in deceased human fetuses of ages 10 to 42 weeks. Results and conclusion: We found no indication of a sexual dimorphism at this early stage of development.
