Male Monogamy Gene
A study performed in Sweden analyzed males' genetic makeup in relationship to their behaviors in marriage and relationships. According to HealthDay, the study suggests that a genetic difference in the gene that regulates vasopressin alters how strongly a male bonds to his partner. Vasopressin is responsible for activating the brain's reward mechanisms. The study finds that men with higher amounts of vasopressin are more likely to remain monogamous.1
