MII, metaphase II; PB, polar body; PN, pronucleus.
Values are presented as N (%). The rates of oocytes with two PNs and two PBs, one PN, or multiple PNs, unfertilized oocytes, and degenerated oocytes were evaluated using the chi‐square test for between group A and each group. A p‐value of <.05 was considered statistically significant.
a
P < .05: significant difference between groups A and C.
