OBJECTIVE The purpose of this study was to investigate growth patterns in human hands, digits and digit ratio (2D:4D) during the fetal period. METHODS The study is carried out on 161 human fetuses (83 males, 78 females) free from external pathology or malformation with ages ranging between 9 and 40 weeks of gestation. Following general external measurements, length and width of the hand, digi...
Many important economic decisions involve financial risk, and there is substantial evidence that women tend to be more risk averse than men. We explore a potential biological basis of the variation in risk-taking within and between men and women using an emerging measure of prenatal androgrens, the ratio between the length of the second and fourth digits (2D:4D). A smaller 2D:4D ratio has been ...
The differentiation of the urinogenital system and the appendicular skeleton in vertebrates is under the control of Hox genes. The common control of digit and gonad differentiation raises the possibility that patterns of digit formation may relate to spermatogenesis and hormonal concentrations. This work was concerned with the ratio between the length of the 2nd and 4th digit (2D:4D) in humans....
