Preincubation of cumulus-oocyte complexes before exposure to gonadotropins improves the developmental competence of porcine embryos matured and fertilized in vitro.


The objectives of the present study were to examine whether delayed exposure of porcine cumulus-oocyte complexes (COCs) to gonadotropins affects the diameter of oocytes, the nuclear morphology of the germinal vesicle, the rate of germinal vesicle breakdown (GVBD), and the embryonic developmental rate of inseminated oocytes following maturation and… (More)
