What is Oxytocin

Oxytocin is a nonapeptide produced in the hypothalamus and released by the posterior pituitary, with peripheral actions in childbirth and lactation and central actions in social behavior, bonding, and sexual response. Injectable and intranasal forms are approved for induction of labor and control of postpartum hemorrhage. Interest in intranasal formulations for social cognition is the subject of clinical research.
