However, Cheiko Mitsui found the answer to the question she was looking for with a stick in her cheek, reached a perfect match and a man who will become her future husband.
The use of DNA to match singles is not just a matter of science fiction series (like the one on Netflix).
Today, there are many areas of matchmaking between individuals that claim to use DNA for “genetic compatibility.”
But what do people who use science to find love think about it?
‘It changed my life’
Cheiko Mitsui says she has been looking for love for ten years before discovering DNA mating.
Mitsui, 45, who lives on the Japanese island of Hokkaido, divorced at the age of 35 and thought he had no chance of falling in love.
“I met at my friends’ parties, I signed up for another marriage agency, but I couldn’t find what I needed,” she says.
Then the path fell to a scavenger named Cheiko Date. He claimed to have matched 700 pairs in 20 years.
In 2014, he started working for a company called GenePartner in Switzerland. One of the founders of the company, geneticist Dr. Pointing out that genetic testing will contribute to mating, Tamara Brown said, “Two things need to come together for a relationship to be successful; one is biological mating and the other is social adaptation.”
Genes important for the immune system
In DNA matching, the leukocyte antigen system (HLA) genes are examined in a swab sample taken from inside the cheek.
Dr. Brown says HLA is important in the immune system, and that more HLA types indicate a better immune system.
“Female and male mammals can detect these HLAs because they want to give birth to disease-resistant babies. This is a simple principle that is important for the survival of the species.”
The roots of this work. Swiss researcher Dr. In 1995, he returned to the “sweatshirt study” by Claus Wedekind. The girls were given shirts worn by different men for two days and asked to evaluate the scents. The results showed that women prefer men’s T-shirts with different genes than HLA genes.
Dr. Brown said GenePartner tested the theory on 250 married couples and found similar results.
“When you meet someone, it’s not your appearance, it’s your love for someone’s HLA that makes you feel affected by something else and you can’t fully express what it is.”
“It’s a very instinctive and fundamental thing; it happens to everyone. Even if you don’t want to have children, that instinct still exists.”
Cheiko Mitsui hopes that DNA analysis will help her choose a long-term partner.
Mitsui paired up with 45-year-old Tomohito in September 2018 in terms of their common interests and concerns, and decided to do a DNA analysis after a month-long meeting.
“The result was 100 percent appropriate. I was expecting a good result, but it turned out better than I expected, I was very happy,” he says.
They decided to get married two weeks later, in September 2019. Mitsui says he feels “safer” as a result of a genetic test.
“I don’t know if I would get married without our DNA test, maybe I would, but the test result forced me to make that decision. In that sense, it has a decisive impact on a person’s life.”
Genetic effect on mating “a little exaggeration”
However, geneticist Dr. Diogo Meyer warns of DNA testing
“It’s a bit of an exaggeration to say that mismatch is determined by genetics. It’s a controversial topic. Some studies show that different individuals are selected for HLA genes in a match, but there’s more research showing that there is no such effect.”
Dr. Meyer likens it to “heads and tails” and says the effect is “accidentally small.”
Ami, 32, who is also in Japan, says she aims to find “someone who will spend the rest of her life” by matching her DNA. After enrolling in Cheiko Date’s DNA test last year, Ami sees the test work with two men:
“When I met the first two men, I saw that they were very nice and educated gentlemen. But the interesting thing is that although I knew they were very good, one thing was missing. I felt comfortable with them, but nothing more. It was a very interesting result for me.”
‘Allows you to make quick decisions’
Dr. The Brown team also analyzes “friendship-based” attraction and sexual attraction in couples.
“Some people don’t care about an ambitious relationship, they want someone’s friendship and support. In this situation, it is possible to adapt to feeling like a family member, especially if they are old and don’t want children. It’s important to decide on the shooting. “
Cheiko Date says most people who want to take a DNA test are well-educated, high-level people and don’t have time to find anyone. “People make decisions faster with DNA tests and feel more confident. I’m glad I can give them that feeling,” he says.
‘Can end the relationship’
Melissa, who lives in Queensland, Australia, said she and her boyfriend “had a hard time” when they decided to take the exam.
She used to have a lot of boyfriends and thinks she lost a lot of time because she couldn’t control their relationship.
Mez met on Tinder in 2017. He thought he was the right person. But in the first year, they had a very rough relationship and stayed for a short time. When they reunited, Melissa persuaded him to take a genetic compatibility test.
DNA tests conducted by a company called DNA Romance found 98 percent compliance. The more different the HLA genes, the higher the adaptation rate.
“I was very happy. Knowing that gave me extra confidence. It was like a new confirmation for me,” says Melissa.
Rodrigo Barquera, a geneticist at the Max Planck Institute in Germany, said it was not enough to predict how successful a link would be, despite information about the role of HLA genes in joint selection.
“Genes are worried about mating and creating the next generation. They don’t care about anything else. Human relationships are more complicated than having children.”
Melissa, 37, says the test says they feel safer, get married and are pregnant with their first child.
However, he admitted that they had put their relationship to the test. “If the test hadn’t been good, we would have had a different situation today; maybe we would have ended our relationship,” he said.
The newlyweds Sienna and Rodrigo Meneses were not inclined to the DNA matching test. The couple, who said their relationship was very good, decided to try and test the system “just to turn off the interest.” As a result of the test, the compliance rate was 90 percent.
“We were very surprised that our natural feelings for each other were scientifically proven. As a result, we were pleased to see the depth of our garden and felt safe,” says Melissa.
Dr. Meyer says the involvement of genetics in relationship-related services has a lot to do with “how science is sold and perceived.”
“It’s an exaggeration of the capacity of science,” Meyer said, adding that he thinks science is closer to the truth and more reliable than other data because it has tests and statistics.
