Can We Smell The Sex We’re Attracted To?

Does sex smell? Science says yes! But not
in the way you’re thinking, ya perverts. Hey guys, Tara here for Dnews – to talk about
everyone’s favorite subject, pheromones. Now we’ve been told for years and years that
pheromones influence our behavior – and help us choose mates – but it’s always been kind
of a question mark as to how much of a difference they really make. Humans in particular, have more secretion
and sweat glands than any other primate, and the organ we use to detect pheromones is called
the vomeronasal organ, or VNO. It’s a tiny, crescent-shaped bundle of neurons at the base
of each nostril, and almost all animals have it – from reptiles, to elephants, to house
cats. What’s surprising, however, is that only 30%
of humans were actually born with this organ. But we can all smell pheromones, right? So
there’s gotta be something else that allows us to detect them. Well, there is. Men secrete something called
andro, which is a metabolite of testosterone, in their sweat and semen. And women, secret
estra, a derivative of estrogen, in their urine. Both chemicals are known to trigger arousal
in the opposite sex – but in order to be considered true pheromones, they have to shape how people
view different genders. New research from the Chinese Academy of Sciences
in Beijing – confirms that that’s exactly what happens. For the study, researchers split men and women
up into groups of 24, and then had them watch this video. Notice the figure on the left,
has a decidedly female strut – with a lot more hip movement – while the figure on the
right, has a flatter gait, typical of most males. The one in the middle – is considered
neutral, meaning it could go either way. They then asked subjects to inhale either
andro or estra – and judge whether they thought the neutral walk was more masculine or more
feminine. Turns out, their judgments depended entirely
on their own sexual preferences. After smelling andro, the male hormone, straight
women perceived the walk as being more masculine. But the pheromone had no effect on straight
men. In contrast, smelling estra, the female hormone
– made straight men perceive the walk as more feminine. While straight women, weren’t affected.
Even more interesting, is the fact that gay men followed the exact same response pattern
as straight women. Meaning homosexual men are more likely to respond to male pheromones
than they are to female ones. Oddly enough, homosexual women – fell somewhere in between.
So neither pheromone made much of a difference. This supports the classification of andro
and estra as “sex pheromones,” but it also shows that they can influence our perception
of gender – but only in the genders we’re attracted to.
Like most pheromones, the smell is imperceptible – so all of these decisions that happen are
subconscious – but they’re still an important part of how we interact and perceive each
other. More importantly, this study shows that pheromones
aren’t gender-specific – but rather, sexuality-specific. Which gives even less ammo to the argument
that sexuality is a choice. Personally, I think everyone smells gross.
But, I also live in a city with almost no air conditioning. And, I attend a lot of gaming
conventions. So, my experience is probably skewed. Speaking of smelly things – and terrible segueways
– if you want more facts about smelly stuff – go check out Animalist’s new show, Best
Breed Ever! It tells you everything you wanna know – and some things you didn’t know – about
your favorite breeds of dogs. FOR EXAMPLE: Did you know that French bulldogs are banned
from most commercial airplanes? It’s true. And when you hear the reason, it actually
kinda makes sense. They’ve got new episodes every Wednesday and Friday, so go check those
