*The 95 % confidence intervals were computed by modified Wald method. Cleavage rate (%) = Total of cleaved embryos/Total retrieval oocytes post culture, except degenerate. Blastocyst formation rate (%) = Total of formed blastocysts/Total of cleaved embryos. Blocked embryo rate (%) = Total embryos that did not reach blastocyst/Total of cleaved embryos. IVC = Intravaginal Culture, IVF = In vitro Fertilization, D3= embryonic culture for three days, D5 = embryonic culture for five days.
