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