Oocytes with polar bodies were considered mature MII oocytes. The fertilization rate and rate of development to the blastocyst stage were compared between G2-PLUS and coculture-DMEM-F12. Both showed no significant differences in their ability to improve oocyte maturation and were statistically different from the rest of the systems. The data were analyzed by the chi-squared test. A value of was considered statistically significant.
