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.
It is given intravenously since it is easily degraded by the body if given orally. While giving oxytocin, it is important to monitor the mother and the fetus, specifically the mother's uterine activity and the fetal heart rate. The more common side effects of oxytocin include tachysystole, hyponatremia, and hypotension. Tachysystole is an ...
Melanocyte-inhibiting factor (also known as Pro-Leu-Gly-NH 2, Melanostatin, MSH release–inhibiting hormone or MIF-1) is an endogenous peptide fragment derived from cleavage of the hormone oxytocin, but having generally different actions in the body.
The presence of hCG in a woman's body indicates that a fertilized egg has implanted in the uterus and the placenta has started to form. 10 days after fertilization, significant hCG can be detected from woman's blood sample. [6] The levels of hCG in the body increase rapidly in the first few weeks of pregnancy, doubling every 48–72 hours. [7]
It is released in response to an increase in oxytocin levels in the uterus, and stimulates both luteolytic activity and the release of oxytocin. [6] Because PGF 2α is linked with an increase in uterine oxytocin levels, there is evidence that PGF 2α and oxytocin form a positive feedback loop to facilitate the degradation of the corpus luteum. [7]
They control the body's response to stress [8] and infection. [9] They regulate the body's metabolism, influencing eating and drinking behaviour, and influence how energy intake is utilised, that is, how fat is metabolised. [10] They influence and regulate mood, [11] body fluid and electrolyte homeostasis, [12] and blood pressure. [13]
