There are well-known sex differences in the epidemiology and etiopathology of alcohol
dependence. Male gender is a crucial risk factor for the onset of alcohol addiction. A directly …

Competing theories have posited roles for foetal androgen exposure in the development of
human handedness. However, due to practical and ethical considerations, few studies have …

The relative length of the second and fourth digits (2D: 4D) is a putative marker for prenatal
testosterone. Low 2D: 4D has been reported to correlate with high performance in sport in …

A scientometric analysis of modern research on the second-to-fourth digit ratio (2D: 4D), a
widely studied putative marker for prenatal androgen action, is presented. In early 2009, this …

It has been reported that there is a high proportion of left-handers among top athletes in
different sports. In this study, the goal was to examine the rate of left-handedness in the top …

Research particularly focusing on male athletes and popular sports (running and soccer)
suggests associations of lower (masculinized) second‐to‐fourth digit ratio (2D: 4D), a …

A smaller length ratio for the second relative to the fourth finger (2D∶ 4D) is repeatedly
associated with fetal male-typical testosterone (T) and is implicated as a biomarker for a …

Familial resemblance in the second‐to‐fourth digit ratio (2D: 4D), a proxy for prenatal
androgen action, was studied in 1,260 individuals from 235 Austrian families. In agreement …

ABSTRACT The Geschwind-Behan-Galaburda and sexual differentiation models predict an
association between elevated foetal androgen exposure and left-handedness whereas the …

Over the past decade a small evidence base has highlighted the potential importance of
seemingly innocuous variables related to one's hands, such as hand dominance and the …
