Is there any reason for man to be unfaithful?

Not that only man are unfaithful as woman can also be unfaithful at times. But it seems mostly man suffer from this problem of cheating. But now scientists now say it may not be a man's fault after all. It's in the genes.

Scientists say man who inherit a genetic variant that affects an important attachment hormone are more than likely to have poorer relationships and are less likely to be married.

The genes are said to affect the hormone which plays an important role in social behaviour, pair bonding and sexual attachment.

The study by scientists in Sweden, also showed that wives and girlfriends of men with the variant are less likely to be satisfied with them as partners.

There you have it, there maybe a reason why man are mostly unfaithful after all.
