Experts have found that the cause of men's infidelity in marriage is heredity. If the so-called attachment hormones are not formed in the body of a representative of the stronger sex, his relationships with women will be fragile, he will have problems in the family or will remain single.
The genetic variation, known as 334, occurs only in males and affects monogamy. Men with two pairs of this gene combination are twice as likely to experience a crisis in their marriage and are less likely to have long-term relationships. They are usually unmarried, and their partners are dissatisfied with their relationships.
Thus, it became clear that if a man looks to the left once, it means that he is predisposed to cheating and it is simply useless to expect loyalty from him.
