Cryopreservation of Oocytes: A Randomized Controlled Trial Comparing Slow-Freezing to Vitrification
Although several reviews of smaller studies of cryoprotectant methodology exist randomized
controlled trials,comparing slow-freeze-rapid-thaw procedure to vitrification of oocytes,
are not available. The purpose of this study is to compare these two methods of oocyte
cryopreservation in human oocytes.
