Ovarian Tissue Cryopreservation

Ovarian tissue cryopreservation is a method used to preserve fertility, whereby the outer layer of the ovary, which contains a great number of your eggs, is removed and frozen for future use.

This method protects female reproductive ability when it is threatened by treatments performed for malignant diseases and can restore normal ovarian function in the future.

Ovarian tissue cryopreservation is a method used to preserve fertility, whereby the outer layer of the ovary, which contains a great number of your eggs, is removed and frozen for future use. A part of the ovaries is removed with laparoscopic surgery or laparotomy and kept frozen in a cryopreservation bank.

The following options are then available in the future:

  • In-vitro maturation of primary ovarian follicles and immature eggs until they reach the mature egg stage and are able to be fertilized using the IVF method.
  • Autologous transplantation, meaning that the ovarian tissue that had been removed is repositioned, with the aim of restoring ovarian function and, by extension, fertility.
  • Heterologous transplantation, meaning transplantation of the tissue in another woman who has lost her reproductive ability.

Ovarian tissue cryopreservation is an internationally accepted method, but its functionality after transplantation is still being researched. Progress is continuous, though, and there is still hope for reproduction.
