The most frequent stage in which the embryos are transferred in our center is that of the Blastocyst, to allow the evaluation of the physiological and natural selection of the embryonic development.

CRYOPRESERVED EMBRYOS

Embryo cryopreservation is typically performed as a preventive measure of OHSS or when the endometrium is not considered optimal for embryo transfer.
Comparing the data of our pregnancy rates between embryo transfers deriving from cycles of vitrification and embryos deriving from fresh cycles, it appears that the percentage of pregnancy is superimposable (fresh ET 55%, ET cryopreserved 50%) and therefore the cryopreservation does not reduce the probability of success of the technique.
