Study discovered the actual part of body that reveals penis size as urologist explains truth behind 'hung smile'

It's the question scientists have been trying to answer for generations.

Instead of focusing on silly little things like what is the meaning of life, or how can we save the planet, many folks have been focused on figuring out exactly what indicates a person's penis size.

We've heard false claims about hands and feet, with one doctor explaining on YouTube that you'd be better off looking at a man's nose if you want to see a trailer before sitting down for the whole film, which would make Pinocchio a very real man if true.

Recently, a urologist has suggested that something far more simple might give away the game, and that's looking at a man's smile, as who wouldn't be grinning from ear to ear when carrying around a big chopper all day.

According to Urban Dictionary, the source of all knowledge, the definition of a 'hung smile' is: "The effortlessly confident, self assured smile of a man with a large member."

And Florida-based urologist and podcast host Justin Dubin has suggested that this may be one of the best ways to sneak a peek at the crown jewels without paying to get into the tower of London.

He said: "If you have a perceived larger penis size, you’ll have a more favourable image to yourself.

"Because you’re more confident in yourself, maybe you do have a big d**k energy because of the fact you believe you have a bigger d**k."

However, there's a pretty big issue with this one, as someone could easily act more confident than they actually are, as Dubin added: "Believing and acting like you have a big d**k, people will think that you do."

He explained this point further in an Instagram post about 'hung smiles', saying: "To me, a hung smile is the facial equivalent of big d**k energy.

"The best advice I can give to any guy wanting to demonstrate BDE? Carry yourself like you’re packing. Or as the great George Costanza once said: 'It’s not a lie...if you believe it'."

So, scientists are still looking for a more definitive way of telling for sure what's going on downstairs, and while it's not something you can get a close look at in public without landing yourself a harassment lawsuit, a study has suggested that someone's anogenital distance (AGD) is perhaps the best evidence for having a massive member.

Researchers at Oxford Academic conducted a study in 2019 which 'showed a direct positive relation with testicular volume and penile length and circumference.'

For those of you wondering, anogenital distance is simply the span between your anus and your genitals. And according to the study, the bigger that span, the better.

After evaluating 794 students aged between 18 and 19 the researchers found that reduced AGD is strongly associated with altered semen parameters and reduced testicular volume.

They also wrote: "Our findings show that AGD is associated with testicular volumes, penile measures and seminal parameters in young adult men. Because AGD is hormonally determined during foetal life, the reported high incidence of reduced semen quality and reduced testicular volume could be related to a reduced androgenic exposure in utero.

"AGD could represent a simple and useful method to evaluate testicular and penile development in adult men."

But remember lads, big or small, the most important thing is keeping it healthy.
