Study Shows
A recent study concludes that on howler monkeys, there’s a characteristic that may be true for a majority of male animals–including humans.
Dr. Jacob Dunn, a lead researcher of the University of Cambridge’s Division of Biological Anthropology, noted that male howler monkeys who call the loudest while mating probably had smaller testes.
Native to Central and South America, this breed of monkey is known to be as one of the loudest animals in the planet. Especially the male ones, they are known for their deep roars which reach up to 140 decibels. According to another study, they use the noise to declare their supremacy. Moreover, they hope to dissuade rivals and attract female howlers as well.
When interviewed by Colin Fernandez of The Daily Mail, the researcher had this to say,
“In evolutionary terms, all males strive to have as many offspring as they can, but when it comes to reproduction you can’t have everything. There is evidence in other animals that 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. However, this is the first evidence in any species for a trade-off between vocal investment and sperm production.”
He even added,
“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. Alternatively, using a large vocal organ for roaring may be so effective at deterring rival males that there is no need to invest in large testes.”
Size doesn’t matter, right? Or does it?
You know, we, humans, have one too many resemblances with monkeys and what’s true for them may be true for male humans, too. With this, we can conclude that guys who catcall, flaunting their brand new cars, posting their six-pack abs, in short guys who are egoistic could have smaller penises. Shocking!
What Psychology says
Supporting this argument, psychologists confirmed that people who usually overcompensate everything might be hiding their insecurities. Completing the puzzle, egoistic guys have smaller package.
