The Relationship between Androgen Receptor Gene Polymorphism, Aggression and Social Status in Young Men and Women.

In both sexes, aggression has been described as a critical trait to acquire social status. Still, almost uniquely in men, the link between aggressiveness and the genetic background of testosterone sensitivity measured from the polymorphism in the androgen receptor () gene has been previously investigated. We assessed the relevance of the gene to understand aggression and how aggressiveness affects social status in a cross-sectional study of 195 participants, for the first time in both young men and women. We estimated polymorphism sequences from saliva and measured aggression and self-perceived social status. Unfortunately, the results did not support our prediction because we did not find any of the expected relationships. Therefore, the results suggest that the genetic association between aggressive mechanisms and polymorphism of the gene is less straightforward than expected, at least in men, and seems to indicate that aggression is not usually used to gain social status in our population.
