According to a new study, a single gene variant in the DNA of a man can keep them from having long-term relationship, and making the commitment of getting married..Hollywood (ChattahBox) – According to a new study, a single gene variant in the DNA of a man can keep them from having long-term relationship, and making the commitment of getting married.

Researchers from the Karolinska Institute carried out the study to look at what impact genes can have on commitment issues with men.

The study, led by Hasse Walum, focused on 552 pairs of couples.

They analyzed them in many different ways, looking at controls such as their family history, etc.

Once that was out of the way, the men were then tested for a gene known as AVPR1A, which is known to impiact the hormone vasopressin.

They concluded that 34% of the men who carried two copies of the gene variant had trouble with their partners, marital problems, etc.

This compared to 15% of men who had only one or no copies of it.

In the men who had two copies of the gene, 30% were not even married.

This backs up a previous study which showcased the gene to keep mice from staying with one mate.

The study was published in the Proceedings of the National Academy of Sciences.
