Fine morphological assessment of quality of human mature oocytes after slow freezing or vitrification with a closed device: a comparative analysis

Table 2 Morphometric evaluation of the amount of CG in human MII oocytes subjected to slow freezing and vitrification with a closed device

	Fresh controls (CO)	Cryopreserved
	Fresh controls (CO)	Slow frozen/thawed (SFO)	Vitrified/warmed (VO)
N° of CG/10 μm	8.10 ± 1.59^a	2.95 ± 0.96^b	2.40 ± 0.84^c

Values are expressed as mean ± SD. Statistical analysis is calculated between columns. Differences in values were considered significant if P <0.05.
^a,bP <0.0001; ^a,cP <0.0001; ^b,c P = 0.086*.
*not significant.
