Sometimes, science is best at confirming what we already know and that is that the men who act the most insecure, the men who are most full of bluster, are really lacking in, shall we say, physical attributes.
According to (University of Cambridge biological anthropologist, Jacob) Dunn’s research, primates with the loudest roars tend to have smaller testicles – resulting 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.
“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.

Or, it could be that those who have a more difficult time reproducing need to bellow the loudest to attract the most possible attention, while a primate who is better endowed might be more confident that he will reproduce.
Regardless, that explains a lot about Donald Trump, Ted Nugent and a lot of the loud-mouthed Republicans. Perhaps now, scientists should study the relationship between big guns and tiny appendages.
