Abstract：Objective To investigate the effect of different maturation methods on mitochondrial functions of oocytes and the possible mechanism. To explore novel ideas for developing assisted reproductive technology (ART). Methods Female mice were used as models and randomly allocated into three groups, COH, IVM and NC control. Oocytes maturated with different methods which were all simulated with those treatments in human IVF cycle. Immunofluorescence were used to measure the mitochondrial membrane potentials and analyze the cy-toskeleton. Results The mitochondrial membrane potential in the COH group was significantly lower than that in NC group and IVM group (P < 0.05). The proportion of normal cytoskeleton including spindle structure and chromosome configuration in the COH group and IVM group were significantly lower than that in the NC group (PCOH < 0.01, PIVM < 0.05). Conclusions Both COH and IVM can affect mitochondrial functions.
