The advent of human oocyte vitrification has resulted in improved oocyte survival and reproductive potential that are equivalent to those of fresh retrieved oocytes. This has led the American Society for Reproductive Medicine (ASRM) in 2013 to change its position and classify oocyte cryopreservation as a non-experimental technique . However, this change in position relied mainly on small-scale trials that came from the most experienced reproductive centers. Indeed, the ASRM had emphasized this fact and questioned whether the results of these trials can be generalized and reproduced in other fertility centers. However, since this change in committee position, there has been an increase in cycles that utilize vitrified oocytes, for the purpose of generating commercial banks of donor oocytes and for fertility preservation . Although limited data is available on the outcomes of these cycles, the recent results show a persistently worse outcomes when using vitrified...
