Swedish scientists find "love-rat" gene


Scientists in Sweden think they have found an answer to a question which has vexed women since the dawn of time: are some men born to be unfaithful?

Research suggests so-called “love rats” may have inherited a genetic variant which makes it harder for them to form lasting relationships.

Swedish scientists examined the DNA of 500 sets of twins, all of whom were in long-term relationships.

“The findings were significant,” said researcher Paul Leichtenstein. “The men which have one or two copies of a specific variation of the gene have twice the risk of encountering problems in their relationships.”

And it appears there is no excuse for ladies with a wandering eye. “We didn’t discover any connection in women. Our hypothesis from the start was that this would be the case. In tests on field mice, this gene had no effect on females,” said Leichtenstein.
