Since the introduction of the oocyte vitrification, there has been an increasing number of clinical evidence demonstrating the potential of this process with applications in donor oocyte programs and, particularly, for donor egg banking. This process continues to be shown safe, and hundreds oocyte cryopreservation babies were born without any apparent rise in hereditary anomalies. The oocyte vitrification does not increase the chance of embryonic aneuploidy or diminish the potential implantation of blastocysts produced after Intracytoplasmic sperm injection (ICSI). In addition, a potential randomized sibling-oocyte study evaluating embryo development in fresh versus vitrified oocytes in patients undergoing IVF cycles using their own oocytes found no recorded variations between fertilization rates or embryo development/quality.
There has been much debate concerning the status and clinical applicability of oocyte cryopreservation. Whereas sperm and embryo freezing has been used with higher pregnancy success rates for a long time to gain prevalent acceptance, oocyte freezing formerly endured from being labeled “experimental”. The situation changed when it was announced that oocyte cryopreservation was not “experimental” any longer.
Improved methods of oocyte preservation and demand for donor oocytes lead to the emergence of the new phenomenon in Ukraine and worldwide – introduction of the commercial egg banks. These are entities able to provide cryopreserved oocytes to intended recipients of egg donation. With the establishment of more egg banks, their impact on overall egg donation cycles is likely to increase.
Egg bank donor and egg IVF turns into a growing segment of the donor egg IVF market in Ukraine.
