Number of retrieved and mature oocytes, and fertilization and cleavage rates.

P<0.05 was considered statistically significant. Control group vs. DZP (Group B); *(P<0.0167). NOTE: Rate of MII oocytes: MII oocytes/total oocytes in ICSI cycle; Normal fertilization rate: two-pronuclear zygotes (2PNs)/total MII oocytes in ICSI cycle or 2PNs/total oocytes in IVF cycle; Abnormal fertilization rate: 1PNs+multi-PNs/total MII oocytes in ICSI cycle or 1PNs+multi-PNs/total oocytes in IVF cycle; Cleavage rate: embryos on the 3rd day of cleavage–stage/total 2PNs; Rate of good quality embryos: good quality embryos/total embryos on the 3rd day; Implantation rate: total number of gestational sac/total embryos transferred; Clinical pregnancy rate: total number of clinical pregnancy/total transfer cycles; Miscarriage rate: total number of miscarriage/total number of pregnancy. Live birth rate: total man–time of live baby/total number of pregnancy.
