Biological outcomes of IVM procedures.

IVM outcomes	IVM1	IVM2	P
Number of cumulus oocyte complexes recovered	7.7 ± 4.5	7.8 ± 5.5	0.9
Oocyte retrieval rate (%)	36.8 ± 18.3	32.4 ± 16.6	0.6
Total number of matured oocytes (MII)	4.8 ± 3.2	4.4 ± 4.2	0.7
Total oocyte maturation rate (%)	62.7 ± 23.9	51.6 ± 32.4	0.4
Percentage of mature vitrified oocyte per procedure/total number of mature vitrified oocyte	57%	43%	/

Data are expressed as mean ± SD.

Oocyte retrieval rate = number of retrieved oocytes / AFC × 100.

Total oocyte maturation rate = number of mature oocytes/number of retrieved oocytes × 100.

Wilcoxon matched-paired signed rank tests were used.
