Question

Quizplus · Accepted Answer

Vasopressin and oxytocin are both hormones that are involved in social bonding and attachment in mammals, including humans. Studies have shown that increases in vasopressin and oxytocin levels can promote pair bonding in monogamous species, such as prairie voles. In humans, variations in the genes that regulate vasopressin and oxytocin activity have been linked to differences in pair bonding behavior, suggesting that these hormones may also play a role in human relationship formation and maintenance.
