Cryopreservation and cryoembryo transfer (KET)

The cryopreservation of embryo is a method by which excess embryos are stored in liquid nitrogen  for  transfer at some point in the future.Cryopreservation is used in cases when more than two or three embryos exist which cannot be transferred in the given cycle due to the risk of a multiple pregnancy. In case of severe ovarian hyperstimulation syndrome or unsuitable conditions for a transfer (e.g. another patient´s acute disease, low endometrium etc.) all embryos are cryopreserved. Not all embryos can be transferred after cryopreservation. Approximately 25% may be damaged through the freezing process.

The success rate of frozen - defrosted embryo transfer (cryoembryo transfer - KET) is a little lower than that of fresh embryo transfer. However, there is an advantage for a woman because no hormonal stimulation, and no further oocyte retrieval are necessary. Based on of contemporary knowledge,the increased risk of abnormalities or inborn development defects following embryo storage in this way is not known.
