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.
Prostaglandin F2 alpha (PGF2α) has been identified as the key luteolytic hormone in many species. [2] PGF2α is released from uterine endometrial cells in a pulsatile pattern when stimulated by oxytocin [3] to stimulate both luteolytic activity and further release of oxytocin from the corpus luteum.
Oxytocin is produced in the brain and several reproductive tissues during pregnancy, while the receptors are produced in reproductive tissues. [35] 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 ...
As for the orgasm connection, oxytocin is produced in the hypothalamus (i.e., the control center of the brain), which is yet another region activated—both in the posterior and anterior—during ...
Produced by Effect Oxytocin: OXY or OXT: Magnocellular neurosecretory cells of the paraventricular nucleus and supraoptic nucleus: Uterine contraction Lactation (letdown reflex) Vasopressin (antidiuretic hormone) ADH or AVP: Magnocellular and parvocellular neurosecretory cells of the paraventricular nucleus, magnocellular cells in supraoptic ...
Fat cells produce an enzyme called aromatase, which converts testosterone to estrogen— and an imbalance in your testosterone and estrogen levels can increase body fat. High aromatase and ...
Oxytocin contracts the smooth muscle of the uterus during and after birth, and during orgasm(s). After birth, oxytocin contracts the smooth muscle layer of band-like cells surrounding the alveoli to squeeze the newly produced milk into the duct system. Oxytocin is necessary for the milk ejection reflex, or let-down, in response to suckling, to ...
