16)] after vitrification were significantly higher when compared with slow-freezing.
s [sup] meta-analysis analyzed five randomized controlled trials between 2005 and 2009 to compare the clinical efficacy of mature (MII phase) oocyte vitrification with slow-freezing.
sup] compared the survival rate and the resumption rate of meiosis of immature oocytes (GV, MI phases) using vitrification and slow-freezing methods.
sup] Multiple centers in the world have analyzed the possible damages to subcellular structures of mature oocytes using slow-freezing and vitrification protocols.
sup], Concomitantly, a randomized controlled trial demonstrated that oocyte vitrification did not increase the risk of embryonic aneuploidy, verified by DNA fingerprinting.
In addition, some studies have compared vitrification of oocytes with slow-freezing by examining morphological appearance, meiotic spindle, DNA integrity, and oocyte configuration.
Embryo vitrification is a well-established method for adult women who have a male partner or wish to use donor sperm for medical and social reasons.
Comparison of survival and embryonic development in human oocytes cryopreserved by slow-freezing and vitrification.
Prospective randomized comparison of human oocyte cryopreservation with slow-rate freezing or vitrification.
