Cleavage rates on day 2 and Blastocyst developmental rates on day 7 after IVF of the COCs recovered from the 6.1 - 8.0 mm follicles in standard IVM for 46 h (as negative controls), or pre-cultured with PMCI–cilostamide 20 h plus IVM 46 h (as positive controls) and pre-cultured with PMCI–BNP/CNP 20 h plus IVM 46 h (as experimental groups). abMeans in the same column with different superscripts were significantly different (p < 0.05)
