This is not a joke. And yes, Jacob Dunn is a real scientist.
In his research at the University of Cambridge’s biological anthropology department, Dunn confirmed something you’ve suspected for a long time: Men tend to overcompensate when they’re lacking certain ‘reproductive traits.’
According to Dunn’s research, primates that exhibit the loudest roars tend to have smaller testicles, which results in less sperm.
“When males invest in large bodies, bright colors, or weaponry such as horns or long canines, they are unable to also invest in reproductive traits,” Dunn said.
Big trucks, roided-out physiques — science thinks that these dudes are packing small more often than not.
“It may be that investment in developing a large vocal organ and roaring is so costly that there is simply not enough energy left to invest in testes,” Dunn said to U.S. News.
So the next time you get cat-called, just refer the person to this study.
