Oxytocin (Oxt or OT) is a peptide hormone and neuropeptide normally produced in the hypothalamus and released by the posterior pituitary. It plays a role in mood, sleep, sex, social bonding, reproduction, childbirth, and post childbirth. Oxytocin is released into the bloodstream as a hormone in response to sexual activity and during labor. This hormone reduces anxiety levels created from stress, enhances ones trust in others, stimulates arousal and orgasm in both men and women and is believed to be one of the main reasons why those with active and healthy sex lives are generally healthier and live longer.
