Abstract
Oocytes maturation, characterized by germinal vesicle (GV) breakdown, formation of the first meiotic spindle, expulsion of the first polar body and arrest in metaphase of second meiotic division (MII), occurs in preovulatory follicles in response to the surge of gonadotropin and leads to an ovulated oocyte in vivo. However, meiotic resumption in vitro occurs spontaneously following removal of cumulus-oocytes complexes (COCs) from the follicle. (omitted)
