... Oxytocin, a naturally occurring hormone in the human body, is said and proved to produce many important physiological actions. Oxytocin when present in optimum level helps to maintain emotional homeostasis, pleasure, love, orgasm and also improves social memory and cognition. Deficiency of oxytocin in the amygdala causes anxiety and fear which are often found in conditions like autism and Schizophrenia. Deficiency of the same at the time of labour leads to uterine inertia and post partum bleeding. These complications are trespassed by the commercial availability of the hormone in various forms. The synthetically produced, oxytocin replacing hormones, pose certain potential threats to homosapiens.Thus further research is being conducted to coin substances that mimic the property of natural oxytocin and also discards the risk which occurs due to external intake.

Oxytocin Essay

- Oxytocin, sometimes referred to as the “love hormone,” has been associated with several types of social behaviors. It acts as both a hormone and a neurotransmitter in the mammalian brain, and it is thought to have co-evolved with another similar peptide, vasopressin.
