IVF-ET laboratory indicators in normal and PCOS patients.

	Normal (n = 44)	PCOS (n = 48)	p-value
Oocytes retrieved (n)	14.89 ± 0.78	16.06 ± 0.82	0.304
Oocyte maturation rate (%)	81.8	78.1	0.079
Fertilization rate (%)	61.9	64.3	0.348
Cleavage rate (%)	99.5	98.5	0.185
Good-quality embryo rate (%)	70.6	59.8	0.000
Blastocyst formation rate (%)	62.2	52.6	0.026

Oocyte maturation rate (%) = (number of MII oocytes/number of oocytes retrieved) × 100; Fertilization rate (%) = (number of fertilized oocytes/number of oocytes retrieved) × 100; Cleavage rate (%) = (number of cleaved embryos/number of fertilized oocytes) × 100; Good-quality embryo rate (%) = (number of good-quality embryos/number of cleaved embryos) × 100; Blastocyst formation rate (%) = (number of blastocysts/number of embryos cultured) × 100. p < 0.05 was considered statistically significant.
