If you wanna know if he loves you so, it’s in his … DNA?

Yep, that’s right — according to a new study, the mystery behind “sparks flying” has finally been solved, and the answer was hiding in our genes all along.


According to the study, published in Nature, the key to attraction lies within a significant genetic component of our immune system called HLA, or human leukocyte antigens.

While the main function of the HLA is to help the body distinguish between healthy cells and viruses or bacteria, the study concluded that it can also affect how sexually attracted you are to a specific person.

To reach this conclusion, scientists studied 254 heterosexual couples between 18 and 60 years old over a nine month period.


They took DNA samples from each person and then had them fill out a survey about themselves and their relationship, with questions ranging from, “How satisfied are you with the sexuality of your relationship?” to, “How attractive is your partner’s body odor without perfumes and colognes?”

In scientific proof that opposites attract, results showed that people with dissimilar HLA had the highest partnership satisfaction.

Both women and men were more sexually satisfied with dissimilar mates, and women were more likely to want children with someone who had very different HLA from their own.

So, if you can’t get enough of someone’s laugh or smile, worry not — it’s not fate or true love, it’s simply a chemical reaction.

Ain’t that romantic?
