Frozen Embryo Transfer – FET

Embryo Freezing and Storage
Vitrification is an advanced freezing technique used to preserve embryos in a protected state. By using special media to prevent the formation of harmful ice crystals, the embryo remains in a glass-like state at an extremely low temperature of -196°C with the help of liquid nitrogen. This method is known for providing the best survival rates upon thawing the embryo, with a success rate of over 80%.

To further protect the embryo’s cells, the fluid in the cavity of the developed embryo, also known as the blastocyst, is reduced. At Ovumia’s fertility clinic in Stockholm, we offer the possibility to store frozen embryos for several years for potential future transfers, known as FET procedures. This flexibility allows the timing of new fertility treatments to be chosen based on the patient’s preferences. One of the major advantages of vitrification is that the quality of the embryos is not affected by the freezing process. It is important to note that, by law, frozen embryos can be stored for a maximum of ten years.

Embryo Transfer (Frozen Embryo Transfer)
Frozen embryos can be transferred to the uterus at an appropriate time during a natural menstrual cycle or a hormonally supported cycle. Our experience shows that over 80% of frozen embryos successfully survive the thawing process.

It is important to note that statistics indicate that, on average, about 40% of frozen embryo transfers result in pregnancy. This figure reflects the successful outcomes we have achieved through our treatments, but it is also important to understand that each case is unique, and results may vary from individual to individual.
