Table 4. Effect of pre-IVM on embryonic development of IVG oocytes.

Pre-IVM	No. of oocytes (replicates)	% of cleaved oocytes	% of blastocysts based on		Cell no. in blastocysts (n)
Pre-IVM	No. of oocytes (replicates)	% of cleaved oocytes	Inseminated oocytes	Cleaved oocytes	Cell no. in blastocysts (n)
–	148 (5)	45.8 ± 9.0^a	12.7 ± 7.1^a	26.9 ± 10.4^a	125 ± 60 (18)
+	207 (5)	63.0 ± 5.5^b	26.1 ± 6.9^ab	41.7 ± 11.4^ab	137 ± 57 (54)
Control*	170 (6)	83.0 ± 5.8^c	40.3 ± 11.4^b	48.7 ± 13.8^b	156 ± 72 (68)

^a–c Values (mean ± SD) with different superscripts within columns are significantly different (P<0.05). * The oocytes collected from antral follicles (2 to 8 mm in diameter) served as in vivo-grown controls.
