WebThe GnRH is produced by hypothalamus and supplied through the bloodstream to the pituitary gland. Parts of the brain send out neural inputs which control the secretion of GnRH. In females, the secretion in particular is controlled by sex steroids through negative feedback. In addition, the hormone causes the release of progesterone and estrogen ... WebInsulin and leptin are peripheral metabolic factors signaling the body needs in energy to the central nervous system. Because energy homeostasis and reproductive function are closely related phenomena, we investigated the respective roles played by insulin and leptin in the hypothalamic control of GnRH secretion.
