Cryopreservation is the method of freezing and long-term preservation of biological items in the liquid nitrogen with the further renovation of their functions after the thawing. This method is recognized to be safe for the biological material. Modern medicine applies cryopreservation for long-term storage of the human reproductive cells and tissues.
Nowadays, the following types of cryoconservation are applied in the reproductive medicine:
Cryoconservation enables long-term storage of biological material with good quality and its future use. The IVF protocol states that the use of cryo-embryos considerably increases the efficiency of female infertility treatment.
Embryos are frozen and stored in the liquid nitrogen (-196°С). Since the temperature is low, biochemical processes in a cell stop, and thus they may be stored for a long time. In future, they can be used to achieve pregnancy with IVF method. In a full IVF cycle, it is possible to get a big number of embryos, and a part of them may be frozen for further use. Cryoconservation poses no threat to the embryo or the health of the future child.
Cryoconservation is performed in the following cases:
Method of oocyte cryoconservation is used to freeze female reproductive cells for long term and use them in future. Female reproductive cells are sensitive to freezing, that is why it is necessary to consult a doctor before performing this procedure.
Oocyte cryoconservation is recommended in the following cases:
Sperm cryoconservation is the method to freeze the biological material to use it in the programs applying assisted reproductive technologies. Sperm cryoconservation is recommended in the following cases:
Those are the reasons why storage of biological material may be an important and wise decision. If you are interested in this option, contact the professionals in our clinic to get a comprehensive answer to all your questions.
