Male extraversion and mating effort linked to testosterone
This study of Senegalese men from the December 2010 issue of Personality and Individual Differences shows that extraversion predicts mating effort and that extraverted men have higher levels of testosterone. By contrast, other Big 5 personality traits (i.e., neuroticism, openness and agreeableness) are unrelated to mating effort and testosterone levels. It looks like the dominance component of extraversion--linked in other studies to testosterone--is crucial.
