What is the cryopreservation of embryos?

In an assisted fertilization treatment, it is usual to transfer 2 or 3 embryos that may have been obtained from oocytes of the woman that is receiving the treatment or from oocytes donated by another woman.In some cases, as a result of ovarian hyperstimulation, more embryos than the ones needed are obtained; these embryos are not discarded, they are preserved at very low temperatures. In order to preserve them, they are placed in labeled airtight glass containers and are immersed in liquid nitrogen within 48 and 72 hours after fertilization has taken place. This way, their metabolism is arrested and they can be preserved for a long time. These embryos will be used in future treatments if the first one is not successful and pregnancy is not achieved, or they will be preserved for the moment the couple decides to have a second child without having to repeat the whole procedure. If the embryos were obtained thanks to oocytes donated by another woman, brothers of different ages but with the same genetic information may be born.

The survival rate after defrosting is between 80% and 85%.
