In-vitro fertilization and embryo development characteristics

	MII Oocytes (N)	Fertilized [N (%)]	Two-cell embryos [N (%)]	Morula/blastocysts [N (%)]
In-vivo matured oocytes	222	214(96.4)^a	204 (95.3)^b	192 (94.1)^c
In-vitro grown oocytes	107	84 (78.5)^a	65 (77.4)^b	50 (76.9)^c

Fertilization, cleavage, and morula/blastocyst formation rates were compared between the in-vivo and in-vitro matured oocyte group using χ² analysis (p < 0.001 for all rates)
