Is there such thing as too sexy?
Researchers from the University of Queensland in Australia have proven it's possible.
The researchers engineered a population of male Drosophila serrata flies to release excess amounts of a combination of pheromones that female flies find super sexy.
Then, through a process of selective breeding, they studied the descendants of the supercharged males.
The study found that while sexual attractiveness in male fruit flies increased over generations, after seven generations the females stop mating with them.
Meaning - there is a biological cost to being too attractive.
Although male sexual traits are often obvious in animals, like the bright colors of a peacock tail and the mane of a lion, an overabundance of sexuality may not be a good thing.
What can human's take from this? One researcher says -
"that very attractive individuals may well have something wrong with them — they may not be as good as they seem to be at first glance.”
We're still not ready to feel bad for Brad Pitt.
