They also proved that both cAMP-regulated steroidogenic enzymes and progesterone production could be inhibited by leptin via the MAPK pathway. Ovarian stimulation for assisted reproduction produces fewer follicles leading to the harvest of fewer oocytes. Both mitogen-activated protein kinase and phosphatidylinositol 3-kinase signalling are required in epidermal growth factor-induced human trophoblast migration. The impact of obesity on reproductive function, especially associated with ovulatory disorders, is mainly due to neuroendocrine mechanisms, which interfere with ovarian functions, and are able to affect the ovulation rate and the endometrial receptivity.
