A new dating site uses DNA swabs to help match couples, and while some may be skeptical, others are embracing the concept.
Pheramor, which was co-founded by geneticist Brittany Barreto and data analyst Asma Mirza, tries to pair couples up based on their DNA, CBS News reported.
"Scientists can actually predict who's attracted to whom," Barreto said per The Houston Chronicle.
"Genetic-based human attraction has to do with pheromones. And when we smell pheromones, what we're actually smelling is how diverse someone's immune system is compared to our own."
Not convinced? Baretto explained that love was all hormonal anyway.
"That's what love at first sight actually is. It's smelling someone's pheromones from across the room, and your brain says, 'Oh my Gosh, that's the most perfect pheromone profile I've ever smelled in my entire life. I love them."
Ron Gonzalez, co-founder of Instant Chemistry which tests DNA for biological compatibility in a long-term relationship, told USA Today that people in long-term relationships had different versions of the serotonin genes and immune systems.
The science is there but David Magnus, the director of biomedical ethics at Stanford, harbors doubts, stating that there are other factors that come into play when determining compatibility.
"Anybody who's signing up for this ought to look really hard at the privacy protections and not just click through the way we usually do when we're online ordering apps," he added, per CBS News.
