Abstract
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 42weeks.
RESULTS AND CONCLUSION
We found no indication of a sexual dimorphism at this early stage of development.
