One study exhibited the proposed effects that oxytocin had on Tsimane men who had been hunting for varying periods of time. [48] Once the men returned home, it was found that oxytocin levels were higher in those men who had hunted for longer periods of time. As a result of the longer time period spent hunting, the increased levels of oxytocin ...
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.

[1] Increased levels of oxytocin promotes social and emotional development, [ 4 ] [ 8 ] and this facilitates lower levels of aggression and other antisocial behaviours .
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 ...
Pain may also occur in those with large breasts, during menopause, and in early pregnancy. [1] [3] In about 2% of cases breast pain is related to breast cancer. [4] Diagnosis involves examination, with medical imaging if only a specific part of the breast hurts. [1] In more than 75% of people the pain resolves without any specific treatment. [1]
