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.
Oxytocin levels in human females are associated with the degree of physical affection and bonding. Feldman (2010) found that mothers who displayed “high affectionate contact” had increased oxytocin levels post interaction, but not mothers who displayed “low affectionate contact. [ 22 ] ”
Oxytocin levels are positively correlated with the amount of affection the father displays towards the child. [60] In humans, and in other primate species, lower levels of testosterone have been linked to the display of paternal behavior. [59] [61]
Involved in orgasm, trust between people, [2] and circadian homeostasis (body temperature, activity level, wakefulness).

It also affects hepatic glycogen levels and gastrointestinal ...
Men experience sexual dysfunction at testosterone levels of below 300 ng/dL, with men that have levels of testosterone of approximately 200 ng/dL often experiencing such problems. [28] Complete loss of testicular testosterone production resulting in testosterone levels within the castrate range (95% decrease, to 15 ng/dL on average) with ...
The human pituitary gland is oval shaped, about 1 cm in diameter, 0.5–1 gram (0.018–0.035 oz) in weight on average, and about the size of a kidney bean. [ 2 ] [ 3 ] There are two main lobes of the pituitary, an anterior lobe , and a posterior lobe joined and separated by a small intermediate lobe .
In 2019, a large review of the effects of oxytocin found that the oxytocin level in fathers that engage in SSC is increased as well. Two studies found that "when the infant is clothed only in a diaper and placed in between the mother or father's breasts, chest-to-chest [elevated paternal oxytocin levels were] shown to reduce stress and anxiety ...
During human parturition, the quantifiable level of blood plasma oxytocin rises: it becomes twice as much during the initial phase of dilation and continues to increase until the second stage of labor. [36] Oxytocin furthermore induces uterine contractions in mothers following childbirth which helps in the prevention of bleeding. [37]
