According to recent research published in the journal Collegium Antropologicum, "The 2(nd) to 4(th) digit ratio (2D:4D) is a sexually dimorphic biometric marker, related to prenatal estrogen and testosterone levels in utero, and determined genetically by the HOX genes. 2D:4D presents a population variation, which seems to be dependent on geographical position or ethnicity, and may reflect differences in prenatal steroid hormone levels among different ethnic groups. In view of its clinical importance, this study investigates the 2D:4D ratio, as well as other digit ratios, in Greek population."
"A sample of 60 Greek men and 60 Greek women (age range 19-25 years) was selected by random procedures. Fingers' length was measured twice, using an electronic vernier calliper (precision 0.01 mm). Men had lower 2D:4D ratio (0.974 +/- 0.035 for the right hand and 0.973 +/- 0.044 for the left hand.) than women (1.002 +/- 0.04 for the right hand and 1.001 +/- 0.045 for the left hand). This difference in 2D:4D ratio between sexes was statistically significant (p
The researchers concluded: "The sexual dimorphism of all digit ratios (except 2D:3D) is stronger in right than left hand."
