Embryo and oocyte cryopreservation

Vitrification, a rapid freezing technique, allows for the storage of embryos and oocytes while ensuring they are not damaged by the freezing. This allows them to be used later, without having to resort to further ovarian stimulation.

Embryo cryopreservation/vitrification:
Viable embryos not implanted into the uterus will be stored by freezing, enabling their implantation in future cycles without necessitating further ovarian stimulation.
A new rapid freezing or vitrification technique is currently used, in which the embryos are not affected by the freezing process and ensures results that are practically the same as those obtained in fresh transfers.

Oocyte cryopreservation/vitrification:
In some cases, in young women and when the ovarian response is high, not all oocytes are inseminated and a few eggs are vitrified. These will serve as a reserve and can be used later, when the patient wishes to become pregnant again, without the need for further ovarian stimulation.
