No Relationship Between Facial Width-to-Height Ratio and Adult Testosterone

The shape of your face appears to map on to a wide range of traits and behaviors, including aggression, psychopathic traits, combat formidably, drive for achievement, competitive successes, performance in negotiations, and unethical behavior. For a while researchers have speculated that facial structure, along with these behaviors and traits, are due to the common influence of the sex hormone testosterone. However, in multi-study analysis of 1041 men's testosterone and facial structure, we found no evidence of an association between facial width-to-height ratio and currently measured baseline testosterone, or of an association between facial width-to-height ratio and testosterone dynamics in the presence of competition.
