Due to gene mutation, people are more likely to fall in love with oxytocin


Romantics have a genetic mutation that makes more cuddle hormone oxytocin – which one study found that they are more likely to fall in love.

According to researchers at McGill University, Quebec, the genetic mutation boosts the mood and ability of more romantic people and encourages them to build relationships.

For their research, the team focused on a gene called CD38, which powers oxytocin, and found that those with two copies were more loving.

Those who have this genetic mutation are more likely to spend more time eating, drinking, talking, and watching TV than those without the gene.

It's not just people with the mutation who are affected – researchers found that in a study of 111 couples, those with the mutation found their partner more caring even if they didn't have two copies of the gene.

They were also more likely to overlook mistakes, swallow pride, and give in to requests – known as "relationship adjustment," according to researchers.

According to lead author Professor Jennifer Bartz, it is the first time that the gene has been linked to human romantic behavior in everyday life.

"Variation can play a key role in behaviors and perceptions that aid attachment in humans," said Bartz.

Her team tracked 111 couples who dated an average of five or six years and had them report on their social behavior and their perceptions of their partner's social behavior for 20 days.

Of the 222 people who participated in the study, 118 also provided genetic information, which turned out to be 65 women and 53 men.

The CD38 gene has two variants, or "alleles" – A and C. Each person has two copies – one inherited from each parent.

Alleles are forms of the same gene with small differences in the sequence of the DNA bases. So the gene can be in three combinations – AA, CC and AC.

Volunteers who inherited a double dose of the "genotype" CC reported higher "community behavior" than carriers of AA or AC.

It was also more likely that her partner acted the same way, even if his partner didn't have the same genetic codes.

Those with the genetic variant also had fewer negative feelings such as worry, frustration, or anger than their counterparts.

They also rated the quality of their relationship as better – and more supportive.

Professor Bartz said, “Given the importance of close relationships for human survival, it is believed that biological mechanisms have evolved to aid in their initiation and maintenance.

& # 39; Individuals with the CC allele reported higher levels of communal behavior during their daily interaction with their romantic partner.

"They also had a higher degree of relationship adjustment."

She added, "These results support the role of oxytocin in the interpersonal processes associated with maintaining close relationships."

They're adding to growing evidence that genetic factors play a role in relationship formation, and dating websites have been launched to combine genetics and matchmaking.

Studies have shown that identical twins raised separately rate the overall quality of their marriages similarly. This suggests a lasting genetic contribution to married life.

Oxytocin, also known as the love hormone, plays an important role in emotional bonding – it inundates a new mother when a child is born and it comes to a head during sex.

Professor Bartz said decades of research on rodents from mice and the socially monogamous prairie vole suggests that oxytocin promotes romantic bonding.

She added, “We are showing for the first time that CD38, a gene linked to oxytocin secretion and rodent social behavior, is also involved in regulating human romantic relationships in daily life.

"In particular, we show that this is related to the community behavior of an individual, for example with the expression of affection in daily dealings with a romantic partner."

The study was published in the journal Scientific Reports.

OXYTOCIN: THE "LOVE" OR "CUDDLE HORMONE" RESPONSIBLE FOR TRUST

Oxytocin, known as the "love hormone", creates trust and generosity.

The chemical is naturally released from the brain into the blood of humans and other mammals during social and sexual behaviors.

It is produced by women during labor to help them bond with their baby and stimulates the production of breast milk.

The chemical is also released during lovemaking and is nicknamed the "cuddle hormone".

Other loving touches, from hugging a teddy bear to petting your dog, also trigger the release of the hormone.
