Oxytocin is a naturally occurring hormone and neuropeptide produced in the hypothalamus and released by the pituitary gland. It plays key roles in bonding, social behavior, reproduction, and emotional regulation.
It is sometimes referred to as the “bonding hormone,” “love hormone,” or “cuddle hormone”, but its functions go far beyond that.
