The research, recently published in the Journal of Neuroscience, shows that the hypothalamus – a part of the brain involved with regulating the menstrual cycle and reproduction – can actively release the hormone in rhesus monkeys. The findings have implications for humans because the reproductive neuroendocrine system (which makes and releases hormones) of rhesus monkeys is identical to humans.That's because it increases insulin production....
The researchers discovered that estradiol – one of three major naturally occurring oestrogen hormones and the predominant one involved in female reproduction – can be rapidly produced in the brain. Estradiol influences other functions in the body including our weight and memory.
Been there, done that. Can't remember it though. Ha.
