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

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

  Fresh controls (CO) Cryopreserved
Slow frozen/thawed (SFO) Vitrified/warmed (VO)
N° of CG/10 μm 8.10 ± 1.59a 2.95 ± 0.96b 2.40 ± 0.84c
  1. Values are expressed as mean ± SD. Statistical analysis is calculated between columns. Differences in values were considered significant if P <0.05.
  2. a,bP <0.0001; a,cP <0.0001; b,c P = 0.086*.
  3. *not significant.
