Data are presented as percent (total number of oocytes). Values with different superscripts are significantly different (P < 0.03) within each oocyte maturation stage of germinal vesicle (GV), metaphase I (MI), or metaphase II (MII). Groups of mice of 8–10 were used for each time point.
IVM: in vitro maturation of control ovarian GV oocytes; IVOM: in vivo oocyte maturation of control ovarian GV oocytes.
