Does Cryopreservation of Ovarian Tissue Affect the Distribution and Function of Germinal Vesicle Oocytes Mitochondria?

Table 1

The maturation rates of the mouse vitrified and nonvitrified tissue-isolated GV oocytes.

Groups	No. of isolated GV	No. of GV reached MII	No. of degenerated	No. of fertilized	No. of 2 cell	No. of 8 cell	No. of morula	No. of blastocyst
Control	261	226; (86.9 ± 4.51)	6; (2.19 ± 1.01)	183; (81 ± 3.46)	163; (89 ± 4.24)	100; (54.6 ± 3.79)	86; (46.9 ± 3.82)	75; (40.9 ± 2.74)
Vitrification	183	92*; (50.2 ± 6.97)	30*; (16.3 ± 6.5)	44*; (47.8 ± 10.85)	28*; (63.6 ± 8.42)	12*; (27.2 ± 4.88)	7*; (15.9 ± 7.64)	5*; (11.36 ± 5.51)

Four experimental replicates were performed for each group. GV: germinal vesicle stage oocyte; MII: metaphase II oocyte. Data within prentices are % ± SD. *Significant differences compared to the control group in the same column (𝑃<0.05).
