Our Mission

At DNA Romance, we are deciphering the essential elements behind the "scent of love" and the ideal personality combinations for successful loving relationships. We are pioneers in understanding how DNA plays a role in human attraction and loving relationships. Our mission is to enrich people's lives by helping them make genuine connections that lead to lasting love. We aim to improve the accuracy of our romantic predictions with each new member.

Key Research Papers

MHC Based Attraction (aka Chemistry) and Relationship Choice

We have selected 235 Single Nucleotide Polymorphism (SNP) markers positioned in candidate genes that have been shown to play a role in the formation of relationships, and we have weighed our analysis towards loci that have been confirmed by several independent studies. Here are some of research papers that we have evaluated in order to develop and refine our predictions.

How similarities or differences in MHC alleles can influence family planning

MHC similarity between couples is known to cause issues with family planning, here are some of the peer-reviewed papers describing the role of MHC similarity and human reproduction.

* found that sperm viability was associated with partners' HLA dissimilarity, indicating that cervical mucus may selectively facilitate later gamete fusion between immunogenetically compatible partners.

Jokiniemi A, Magris M, Ritari J, Kuusipalo L, Lundgren T, Partanen J and Kekäläinen J (2020) Post-copulatory genetic matchmaking: HLA-dependent effects of cervical mucus on human sperm function Proc Biol Sci., doi: 10.1098/rspb.2020.1682. Epub 2020 Aug 19.

* found an increased frequency of homozygosity for HLA-E*0101 in Egyptian women with RM

Mosaad YM, Abdel-Dayem Y, El-Deek BS and El-Sherbini SM (2011) Association between HLA-E *0101 homozygosity and recurrent miscarriage in Egyptian women. Scand J Immunol. 2011 Aug;74(2):205-9. doi: 10.1111/j.1365-3083.2011.02559.x.

* proposed a genetic-risk calculation that could predict recurrent miscarriage (RM) based on analysing HLA haplotypes from couples either with histories of successful pregnancies or RM.

Mora-Sánchez A, Aguilar-Salvador D, Nowak I (2019) Towards a gamete matching platform: using immunogenetics and artificial intelligence to predict recurrent miscarriageNPJ Digit Med Mar 7;2:12. doi: 10.1038/s41746-019-0089-x

* performed a meta-analyses of 41 studies and showed that HLA-B sharing and HLA-DR sharing were both associated with the occurrence of RM.

Meuleman T, Lashley LE, Dekkers OM, van Lith J, Claas FH and Bloemenkamp KW (2015) HLA associations and HLA sharing in recurrent miscarriage: A systematic review and meta-analysis Hum Immunol. May;76(5):362-73. doi: 10.1016/j.humimm.2015.02.004.

* identified differential association of alleles in HLA-A, HLA-B, HLA-C, and HLA-DRB1 when compared with reported world RSA patients.

Shankarkumar U, Pawar A, Gaonkar P, Parasannavar D, Salvi V, and Ghosh K (2008) HLA allele associations in idiopathic recurrent spontaneous abortion patients from India J Hum Reprod Sci. 2008 Jan;1(1):19-24. doi: 10.4103/0974-1208.39592.

* describe the relationship between HLA similarity at individual alleles, as well as HLA haplotypes as indicators for increased risk of fetal loss among Hutterite couples.

Ober C (1999) Studies of HLA, fertility and mate choice in a human isolate. Hum Reprod Update 5(2):103-107.

* results of a 10 year study that demonstrated increased fetal loss rates among Hutterite couples matching for HLA antigens.

We care about your privacy and have several measures in place to keep your personal data secure. You can help your'self by blocking any profiles you don't like, all users have free unlimted blocking.
If you identify a suspicious user please use the "report" button and we will flag the account for further investigation. Scammers, troublemakers and those violating our terms and conditions will have their email and IP address banned from using DNA Romance for life.

We've been asked by customers to include race but, the definintion of race is ambiguous. To allow people from minorities to find each other we have provided options for matchmaking based on similar geographical location and shared religion or life philosophy.
We certainly agree with the words of Jane Elliott that "There Is Only One Race. The Human Race".
So DNA Romance don't use race to describe the many different phenotypes of humans resulting from differences in population ancestry.
While we do appreciate a person's preference for different colours, we are still considering how to thoughtfully accomodate our customers preferences and potentially intergrate a field to describe your skin tone, or search for matches with specific skin tones, please send us an email if you have any helpful suggestions on this topic.

We accept your autosomal DNA data from several 3rd party DNA testing companies, please login to your account with the company who did your DNA testing (either ere are instructions to login and download your data from either: 23andMe, or Ancestry DNA, or Family Tree DNA, or We Gene, or My Heritage, or Dante Labs, or Genes For Good, or Vitagene, or Living DNA. and request to download your raw autosomal DNA data. Once your raw DNA data is downloaded, save it to a secure location and then use this file to complete your DNA Romance profile.

Yes, evidence from several studies show that the same rules of attraction also apply for relationships between people in the LGBTQ community.

To assist with our guidance on relationship compatibility we have developed a scale that uses the 16 personality types from the Myers Briggs test and provides maximum weight to compatible personality types, and less weight to personality types that tend to clash.

Research shows that the rare sensation of chemistry is felt by people who are genetically compatible. Our bodies are naturally programmed to feel receptive and welcoming to people who are genetically compatible. You can read more about how the genes for love influence our feelings of "romantic chemistry", as well as influence other aspects of our relationships.

Yes, you can purchase your personal DNA testing kit from DNA Romance right here.

Yes, we accept DNA data transfers from many of the direct to consumer DNA testing companies. Here are instructions to login and download your raw DNA data from 23andMe, or Ancestry DNA, or Family Tree DNA, or We Gene, or My Heritage, or Dante Labs, or Genes For Good, or Vitagene, or Living DNA.

Each of us have a unique combination of several hundred genes corresponding to our immune responses which protect us from some diseases and not others, everyone is different and no one person is resistant to every disease known to humanity.


Our sense of smell (olfactory system) is so highly evolved that we will find someone’s’ smell to be pleasant if they are resistant diseases that we aren’t. Our sense of smell is wired to our brain and detects potential relationship partners who are resistant to different diseases. This is important because when one person is sick, then the other might be healthy. In addition children will inherit a more diverse set of genes from their parents (protecting them from form more diseases than either parent alone).


The relationship between immune system genes and attraction (mate-pairing) is not exclusive to humans, major histocompatibility complex (MHC) dependent mate selection has been described in many vertebrates including fish, birds, primates. Please refer to our blog and reference list for dozens of research papers describing this phenomenon.

Don't take it to heart, it's likely they havent checked their email or loged onto the site recently. If you don't want to interact or see their profile again hit the block "delete" button, or move them to your maybe list to see and communicate with later.

Yes, our refer a friend program rewards you with a money for everyone who makes a purchase on DNA Romance based on your referral. In addition our partners also receive ongoing commissions based on the activity of other people they recruit to this partner program.

We respect your right to be forgotten, and you can delete your profile and raw DNA file in the settings section of your DNA Romance account dashboard.

Olfactory is another word for your sense of smell, and what's interesting is that you can actually smell other people's scent profiles which corresponds to different immune receptor proteins. If their natural body odor smells good then you have different MHC genes and will be attracted to that person for a relationship or friendship. If they smell awful then they are likely to have similar MHC genes and there is probably no sexual “chemistry” between you two.

DNA can be collected in many ways but DNA Romance use the "Cheek Swab" method. Our DNA Collection kit is simple to use, just swab the inside of both cheeks and return your sample to the laboratory by mail! No blood, no pain, no sweat!

If you already have raw DNA testing data from 23andMe or another DNA testing company, simply upload your raw autosomal DNA to you profile and your matches will appear within ~2 minutes. If you don't recieve your matches within an hour please check your file is correct, and if the problem persists please email tim@dnaromance.com

The DNA testing takes 3-4 weeks to complete based on the time your samples arrive in the lab. You can order your personal DNA testing kit now.

Your genetic data is encrypted once you upload it to DNA Romance, and then the relevant DNA markers will be incorporated into our matchmaking algorithm. Within ~2 min you will see your DNA Romance matches.

Our DNA romance score reflects your potential for chemical attraction with another person but, this is not everything in a relationship. We do our best to provide additional matchmaking information including a personality compatibility score, and show a picture but every person is an individual with different experiences. Like any online dating site DNA Romance provide a short-list of matches whom you can communicate with and see if there is a meaningful connection. No dating site replaces the need for a first date, to look each other in the eyes, talk, smell each other and mutually see if there is a meaningful connection.

There are many options for a first date depending on your surrounding location. A date usually involves a meal or drink. The classic first date is a chat over coffee or tea, but alternatively you could ask them out for lunch or dinner. During the pandemic we encourage you to make a video call to get things started. Some first and many 2nd dates onwards involve an activity like ten pin bowling, or going to a sports game. After a good first date you should follow-up and suggest a second date.
As for the dress code we recommend that you gauge this based on your proposed location and the activity. In most instances smart casusal is a safe bet.

Yes, our affiliate/partner program rewards you with a commission for every person who finds us based on your referral and makes a purchase. In addition our affiliates receive ongoing commissions based on the activity of other affiliate marketers you refer to us.
