So we're saying, you're not going to find your soulmate but you're probably going to go on a better first date. What Pheramor is actually comparing are 11 genes of the major histocompatibility complex MHC , which code for proteins on the surface of cells that help the immune system recognize invaders.

The mice detected those genes through scent. Researchers hypothesized reasons for this selection ranging from the prevention of inbreeding to promoting offspring with greater diversity of dominant and recessive genes. But experts caution the science behind matching you with someone who has different immune system genes remains theoretical. One is Tristram D. Wyatt , a researcher at Oxford who authored a paper on the search for human pheromones published in the Proceedings of the Royal Society.

And another research group using the same data but slightly different assumptions and statistics said the opposite. None of this is true. But the science of pheromones—specifically human pheromones—is still cloudy at best. First identified in , pheromones are invisible chemical signals that trigger certain behaviors, and are used for communication in animals from moths to mice to rabbits.

Is love really just a cheek swab away?

Since then, companies have claimed to use pheromones in everything from soap to perfume to help humans attract a mate. In their defense, there are several challenges: For one, you have to isolate the right chemical compound. However, later attempts to isolate and test alleged pheromones—such as steroids in male sweat and semen or in female urine—have failed. And in , a review on the scientific literature on pheromones found that most research on the topic was subject to major design flaws.

Right now, Wyatt thinks our best bet for hunting down the first human pheromone is in maternal milk. However, Pheramor could actually help expand that research—by increasing the data available for future research on MHC-associated partner choice. What if the type of people we're into is determined by the very same internal code that dictates whether or not we like coriander? Thankfully, there's now a service that can help you decipher your As, Ts, Gs and Cs and get to the bottom of this love thing once and for all.

DNA Romance is a website that promises to match you with potential partners based on your genes. The theory is that your body produces chemical signals, as determined by your DNA. When a potential partner detects these signals supposedly by smelling them , it creates 'chemistry'—an innate sense of attraction that can't be credited to your height, lack of debt or ability to play bass guitar. However, our ability to smell each other is often confounded by the deodorants, perfumes and colognes we wear.

Now, DNA Romance is getting straight to the genetic source of chemistry. It's an interesting hypothesis but not really a new one. As the only person in the Particle team who lacks a significant other, it was natural that I be the one to test it. After all, if gorillas can use a dating app to find love, why can't I? Why should I get out of my pyjamas and put make-up on and go outside and try to be charming when my genes could do all the heavy lifting for me?

Also, if this scientific approach to finding love doesn't work out, that's OK too.

Can you smell the perfect partner?

Because instead of blaming my singledom on my personality or the fact that I eat peas one at a time, I can blame it on my ancestors. So like the dutiful, single lab rat that I am, I spat in a little plastic tube, stuck it in a post box and sent it off for processing at the AncestryDNA factory. A little while later, they slid into my inbox the results of my heritage and a text file of my raw genetic data. Also, I now have a second cousin in Sydney.

Anyway, I took the raw genetic data file and submitted it to the DNA Romance website along with my personality type , my gender and my sexual preference.

The evolution of odour preference

I also uploaded a photo. I chose one taken of me at my graduation ceremony. I'm mid-laugh and wearing a mortar board. I like to think it makes me look fun and also smart but also not weird. The very same photo I use for my author profile picture on this page, in fact. Which you'd think would make me feel pretty great—look how compatible I am! But automatically, I feel that DNA Romance is less satisfying than something like, say, Tinder because you don't get that sparkly little self-esteem boost every time someone chooses to match with you.

These poor fools can't help if they dig me or not. It's just who they are. But actually, the high proportion of perfect scores makes me wonder if being a match for someone is the norm and it's more unusual to find someone with DNA who is incompatible. Anyway, after a quick scroll through these matches, it was apparent that DNA Romance has been more of a hit in the northern hemisphere.

Canada, UK and USA all had heavy representation, whereas there was only one Aussie—a year-old guy from Sydney who had a Japanese manga character as his profile picture. When I asked him what he liked about the site, he said he forgot that he subscribed.

But what does that mean? What is it about Mr Shin-chan and I that is so perfectly compatible? Other research has found preferences for odour shift across relationship status, contraceptive use , and ovulatory cycle , while one study has shown indifference towards similarity altogether. Safe to say, there is little consensus amongst the scientific community as to how, and even if, MHC-dependent selection operates in humans. To see if people actually do match based on MHC, scientists have genotyped multiple populations and tested the similarity of partners. Most of these results have either found no effect of MHC genes or found that populations are actually more similar in MHC genes than expected by chance.

Only one study has shown convincing evidence of MHC-dissimilar preferences. MHC-dissimilarity preference in this case may have been a method of avoiding inbreeding, rather than a search for diverse immune system partners. Women reported lower levels of sexual responsiveness and sexual satisfaction when they shared MHC genes with their partners.

No effect was found for males, though, and the strength of this effect in women varied over the ovulatory cycle. From a comprehensive review of a large number of studies from multiple populations, across multiple methodologies, researchers have concluded:. Yes, in a very tricky, context-dependent, multi-interactional way. Choice of relationship partner is an immensely complex ballet of biology, culture and circumstance; genes are just one part of the story.
