Values are expressed mean ± SD
No. patient number, Deg. degeneration oocyte, SR survival rate, MR maturation rate
asurvival rate = total oocytes extracted minus the number of degenerated oocytes / total oocytes extracted)
bmaturation rate = MIIoocytes / total extracted oocytes minus the degenerated oocytes)
Qualitative data were expressed as numbers and compared using the non-parametric Mann-Whitney’s U test. (P < 0.05)
