One of the major advances that have occurred in the field of assisted reproduction is the ability to cryopreserve oocytes with the method of vitrification. Embryokosmogenesis is one of the first units in Greece to apply this method of cryopreservation with very good results, both in terms of oocyte survival after thawing, and in terms of achieving fertilization and pregnancy. Thus, in cases where a woman is at risk of losing the ability to produce oocytes (e.g. women who are about to undergo chemotherapy - radiation due to a malignant disease) or is likely that her fertility will be reduced (e.g. women who have a family history of early menopause or women who are under the pressure of age and have not yet chosen the right partner), has the choice to cryopreserve her eggs in our unit for future use. The woman will have to go through the process of ovarian stimulation and oocyte retrieval.
The collected oocytes are then cryopreserved and stored in liquid nitrogen.
