Indeed, it has been postulated that the possible mechanisms by which repetitive ovulation could influence the development of ovarian carcinomas include an increased formation of inclusion cysts, repeated bathing of the surface epithelium by an estrogen-rich follicular fluid, excessive production of growth factors or cytokines, and an aberration of the repetitive repair process that follows the trauma to the surface epithelium as a consequence of ovulation.
