Are Frozen Egg Transfers (FET) often successful?
Frozen eggs, thawed later, do lose about 50% of their fresh potential. You can imagine how difficult it is to perfectly preserve anything in this way! So, fresh is always better than frozen.
Anyway, the Fertility Clinics do have very strict criteria for choosing eggs that may be frozen – and they will only implant embryos that have been grown successfully in the laboratory for two days. Even then, the likelihood of a successful pregnancy is still lower than that of a fresh cycle.
