Not all embryos will survive freezing and eventual thawing when they come to be used. Very occasion-
ally no embryos will survive.
It is not uncommon for those embryos that do survive freezing and thawing to lose a cell or two. Ideally the embryos should continue to divide between thawing and transfer.
Together we deliver.
As embryo transfer is involved in using frozen embryos, the same risks apply.
Current research has not seen any evidence suggesting a risk to patients or to children born from frozen embryos. We will continue to review the evidence available on embryo freezing and the long-term results of frozen embryo transfer.
Clinics are required to offer counseling to all patients undergoing this process – it can be particularly helpful at this time.
