Even if inflammatory mediators contribute to ovarian physiology, dysregulation of the inflammatory response can affect ovarian reserve and oocyte quality. Our aim is to investigate the mechanisms underlying the exacerbated inflammatory response in ovarian microenvironment associated to advanced reproductive age. Since, oocytes develop in the context of ovarian follicles, we obtained follicular fluid (FF) from women with indication of assisted fertilization treatment and we investigated ovarian immune cell profile associated with clinical parameters. First, we confirmed a negative correlation between the number of oocytes and age. In our population (n=70), we identified two subpopulations: women with >10 oocytes (corresponding to the youngest group, from 21-29y) and
