The Genes For Love

Genes positioned in the Major Histocompatibility Complex (MHC) play a key role in our immune Responses, and even our relationship choice. Humans populations naturally maintain diversity in these genes through mate choice, our bodies are guided by our senses to find someone who we really connect with.

The Genes For Love Are Located Within The Major Histocompatibility Complex

Scientifically speaking "Romantic Chemistry / Sexual Chemistry" is determined by the Major Histocompatibility Complex (MHC) a group of proteins that pepper the surface of your cells that help your immune system to recognize and fight pathogens. The MHC genes are also known to influence mate-choice in many vertebrates, and variations in the DNA code of MHC genes are known to influence human partner choice. The sweaty t-shirt experiments demonstrated that MHC influences both body scent and body scent preferences in humans (Wedekind et al., 1995 ,...etc...Kromer et al., 2016), where people with very different MHC genes tend to find each others scent pleasant, while people with similar MHC genes will find each other's scent to smell repulsive. Opposites do attract!

Online Dating Opposites Attract

A study in an Asian American population found that MHC-based attraction AKA "Romantic Chemistry" is just as important as "Personality type"when predicting second date offers (Wu et al., 2018). MHC genes also play a role in partner choice of other vertebrates, an facinating study in obligate pair-living lemurs showed that couples with mismatched MHC genes tend to make an extra-pair partner selection the cause of lemur affairs (Schwensow et al., 2008). MHC compatibility is so important that scientists have proposed humans invented kissing as a way to test for chemistry, and this biological phenomenon can even help explain the strength of the female orgasm (Sherlock et al., 2016).

In the process of sperm donation, selecting the right donor is more than just about physical characteristics and health history. Genetic compatibility plays a crucial role in ensuring the potential for healthy offspring. Our platform, DNA Romance, allows you to unlock some of this critical information hidden in DNA data. We predict compatibility of immune systems between sperm donors and recipients. Using DNA Romance is straightforward: upload the raw autosomal DNA data file, and within approximately two minutes, you'll have insights into potential genetic matches in our database of donors and recipients.
