What is embryo banking?
Embryo banking is the storage of fertilized eggs until you are ready for them. Fertilized eggs, also known as embryos, can be stored for an extended period of time.
Why would I bank embryos?
Embryos can be banked for a variety of reasons:
Single embryo transfer – We promote single embryo transfer for all of our in vitro fertilization patients. Because multiple eggs are often harvested and fertilized, there can be a surplus of eggs after an IVF retrieval. The surplus embryos can be frozen and stored for use in future cycles. This limits the numbers of retrievals necessary for successful fertility treatment.
Fertility preservation – A couple may choose to bank their embryos if they wish to extend the time they have to grow their families. This may happen for a variety of reasons including medical issues and career requirements. By banking embryos, a couple is able to have a healthy pregnancy with eggs and sperm that are retrieved when they are most likely to result in a healthy embryo.
How are the embryos frozen?
We use the state of the art fertilization method of vitrification. Vitrification is a method of flash freezing embryos so that they are not damaged by ice crystals.
With traditional freezing methods, embryos are slowly cooled until they reach their storage temperature. Unfortunately, the slow cooling of the egg results in the formation of ice crystals which can severely damage embryos. With traditional freezing methods, the survival rate for embryo freezing and thawing process is 55%.
- Embryos are fertilized
- When they’ve reached the desired maturity, a protectant is added to the egg and the water removed.
The embryo is flash frozen, reducing the temperature instantly from 98.6 degrees to -320 degrees. Freezing the eggs instantaneously virtually eliminates the chance of ice crystal formation. Because of this, vitrification has a success rate of surviving the freezing and thawing process of 98%. When the embryos are thawed, the process is reversed. The temperature of the frozen embryos are increased, the protectant is removed, and water is added. This process does not damage the embryos.
