Cryopreservation of Embryos for Fertility Preservation


Virginia IVF and Andrology Center offers embryo freezing for the purpose of fertility preservation in medical need situations.


Women who are to undergo surgeries or therapies that could affect their reproductive ability are often recommended to undergo in vitro fertilization (IVF) prior to their treatment if they wish to maintain the potential to have children of their own in the future.


Pre-embryos are routinely cryopreserved at the zygote (fertilized egg), cleaved pre-embryo , or blastocyst stage. The stage at which the pre-embryos are cryopreserved depends on many factors. Such factors as the patient's age, the number of zygotes generated, and the quality of the pre-embryos contribute to deciding how many, and at what stage the pre-embryos should be cryopreserved.


The first step in this process is to contact or have your physician contact one of Reproductive Endocrinologists in order to expedite a consultation. Timing is critical for both egg retrieval and your treatment; so consider starting this process as soon as possible.


After pre-embryos are frozen, they must be specially stored and maintained at -196 0 C in liquid nitrogen tanks to keep them appropriately preserved for future use. Virginia IVF & Andrology Center can maintain storage of your pre-embryos until such time as you choose to utilize them for a future transfer. Currently, there is no evidence that the length of time in storage affects the ability of a cryopreserved pre-embryo to survive and develop into a normal baby.


Cryopreserved embryos are stored in our cryostorage facility under our storage policy.
