| IVOM for 3 h | – | 0.0 (170) | – | 1.2a (170) | – | 98.8a (170) |
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.
