Abstract: The second to fourth digit ratio reflects prenatal estrogen and testosterone exposure and it is established in utero (Bunevicius et al., 2016). Digit ratio (2D:4D) denotes the relative length of the second and fourth digits. Many authors considered this ratio to be a biomarker of the balance between fetal estrogen and testosterone in a narrow window of early ontogeny (Manning et al., 2014). Males and females generally have different finger proportions. Thus, in men, the 2 nd digit is shorter than 4 th digit, but in women, 2 has an equal length or longer than the 4 th digit. Our study is particularly about the digit ratio 2D:4D, but 2D:3D and 3D:4D, too in men populations. The research was made in two localities of different counties of Romania: Baru (of Hunedoara county) and Oradea (of Bihor county). Our aim was to identify possible significant differences between the two male populations. The results are important because demonstrate the differences between the two men populations coherently the digit ratio. nd
Keywords: digit ratio, digit length, biomarker, men populations, fetal sex hormones.
