There is considerable evidence supporting the existence of a difference in levels of aggression between men and women. It has also been proposed that testosterone levels could be related to aggressive behavior. This study explores the possible correlation of two different forms of dominance -sociable and aggressive dominance- and an indirect measure of fetal testosterone levels, the 2D:4D ratio, in a group of soccer players from the formative categories of a First Division team in Uruguay. The results obtained show a mild positive correlation of the 2D:4D ratio and aggressive dominance, but not sociable dominance. This paper discusses the results in the light of conflicting observations made in other populations. Additionally, basic psychometric properties of the sociable- and aggressive dominance scales applied in this study are presented.
