I was given a success rate of 20 % with a FET cycle. Is that right and is it because the embryos don’t always thaw properly? What I want to know is whether once the embryos have thawed properly, is there the same chance of them implanting as with a fresh embryo or is it not as good.
Frozen – thawed embryos loose about 50% of their fresh potential This is due to the very stressful freezing and thawing process. Thus, fresh is always better than frozen. The quality of the embryos that are frozen is also very important and embryos should fulfil strict criteria before being chosen to be frozen. Once the embryos have thawed and PROVEN their ongoing potential by being grown in the lab for two days, the likelihood of a successful pregnancy is still lower than that of a fresh cycle.
