Oxytocin is a peptide hormone and neuropeptide normally produced in the hypothalamus and released by the posterior pituitary. [4] Present in animals since early stages of evolution, in humans it plays roles in behavior that include social bonding, love, reproduction, childbirth, and the period after childbirth.
Orally-administered Oxytocin has been shown to increase putamen responses to facial emotions in humans. [42] Oxytocin administered orally produces different effects on human behaviour and brain function than when given intranasally, possibly due to variations in the molecular transport and binding mechanisms.

Oxytocin is another chemical in the feel good cocktail that orgasm produces and one that affects women more so than men—namely because “when female brains develop in utero there are more ...
The following is a list of hormones found in Homo sapiens.Spelling is not uniform for many hormones. For example, current North American and international usage uses [citation needed] estrogen and gonadotropin, while British usage retains the Greek digraph in oestrogen and favours the earlier spelling gonadotrophin.
The oxytocin receptor, also known as OXTR, is a protein which functions as receptor for the hormone and neurotransmitter oxytocin. [4] [5] In humans, the oxytocin receptor is encoded by the OXTR gene [6] [7] which has been localized to human chromosome 3p25. [8] Evolutionary tree of the oxytocin, vasotocin, mesotocin and isotocin receptors and ...
Oxytocin is released at orgasm and is associated with both sexual pleasure and the formation of emotional bonds. [13] Based on the pleasure model of sexual motivation, the increased sexual pleasure that occurs following oxytocin release may encourage motivation to engage in future sexual activities.
Human and animal studies (reviewed in Taylor et al., 2000) suggest that oxytocin is the neuroendocrine mechanism underlying the female "befriend" stress response. [1] Oxytocin administration to rats and prairie voles increased social contact and social grooming behaviors, reduced stress, and lowered aggression.
