Data are presented as percent (total number of oocytes). Values with different superscripts are significantly different (P < 0.0001) within each oocyte maturation stage of germinal vesicle (GV), metaphase I (MI), or metaphase II (MII). Groups of mice of 7–8 were used for each experiment.
IVM: in vitro maturation; IVOM: in vivo oocyte maturation.
