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.
Synthetic oxytocin, sold under the brand name Pitocin among others, is a medication made from the peptide oxytocin. [ 6 ] [ 7 ] As a medication, it is used to cause contraction of the uterus to start labor , increase the speed of labor , and to stop bleeding following delivery . [ 6 ]
Due to the similarity of the two hormones, there is cross-reaction: oxytocin has a slight antidiuretic function, and high levels of AVP can cause uterine contractions. [ 5 ] [ 6 ] In common with most active peptides, both hormones are synthesised as larger protein precursors that are enzymatically converted to their mature forms.
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 ...
In posterior pituitary we have hormones that control absorption of water and oxytocin. Anterior hypophysis, neurosecretory cells which release hormones. There is a pituitary portal system, with which the hormones are transported. These hormones are prolactin, growth hormone, TSH, adrenocorticotropic hormone, FSH and LH.
Antidiuretics reduce urine volume, particularly in diabetes insipidus (DI), which is one of their main indications. The antidiuretic hormone class includes vasopressin (ADH), argipressin, desmopressin, lypressin, ornipressin, oxytocin, and terlipressin. Miscellaneous others include chlorpropamide and carbamazepine.
Functional medicine provider Dr. Austin Lake of Tulsa, Oklahoma, breaks down several women's health issues that he hopes the burgeoning MAHA movement will address.
Tachysystole is an increased rate of uterine contractions. If this occurs, it can be managed by lowering the dosage of oxytocin. Hyponatremia is a decreased concentration of sodium in the body as a result of increased fluids. This occurs due to oxytocin's similar structure to vasopressin (antidiuretic hormone), which acts to retain water in the ...
