A safe option for your fertility
Embryo freezing, also called embryo cryopreservation, is an assisted reproduction technique that allows embryos to be preserved in liquid nitrogen at –196 °C for future use.
Thanks to vitrification, embryos maintain their viability and quality intact for years, with survival rates after thawing above 95%.
Embryo freezing is useful in a variety of situations:
The patient’s eggs (or donor eggs) are fertilized with partner or donor sperm in the laboratory.
The embryos develop in state-of-the-art incubators for several days.
The best-quality embryos are chosen.
The embryos are frozen extremely rapidly, preventing ice crystal formation.
They remain in liquid nitrogen until needed.
When the patient wishes to try again, frozen embryos are thawed and transferred to the uterus in either a natural cycle or a medicated cycle.
Frozen embryo transfer is a simple, painless procedure with success rates comparable to fresh embryo transfer.
Indefinitely. The law in Spain allows its storage with the consent of the partner or patient.
