Embryo Cryopreservation and Frozen Embryo Transfer Process (FET)
What Is Embryo Freezing?
Embryo Freezing is a modern fertility preservation method used to store healthy embryos obtained during IVF treatment for future use. With Embryo Freezing in Cyprus, couples can preserve their chances of pregnancy without needing to repeat ovarian stimulation or egg retrieval procedures.
Using advanced laboratory technologies, embryos are safely frozen and stored until the couple decides to proceed with pregnancy.
Today, Embryo Freezing in Cyprus has become an essential part of assisted reproductive treatments, particularly when multiple high-quality embryos are obtained during an IVF cycle.
The first successful pregnancy using a frozen embryo was achieved in 1983, and with modern vitrification techniques, success rates with thawed embryos are now remarkably high.
On Which Day Are Embryos Frozen?
During the IVF process, embryos are typically frozen on day 5 or day 6, when they reach the blastocyst stage of development.
Embryos at this stage have a higher implantation potential and are more suitable for freezing.
High-quality embryos that remain after embryo transfer can be preserved for future use with the couple’s consent.
Embryo Freezing in Cyprus is especially beneficial in situations such as:
- When the first embryo transfer is unsuccessful
- When couples plan for a future sibling
- When embryo transfer must be postponed for medical reasons
How Is Embryo Freezing Performed?
The most widely used method for Embryo Freezing is called Embryo Cryopreservation, an advanced rapid-freezing technique.
Vitrification prevents the formation of ice crystals inside the embryo cells, helping maintain their structural integrity and viability.
Embryo Freezing Process
The process typically includes the following steps:
- Evaluation of embryo quality by the embryology team
- Selection of embryos at the appropriate developmental stage
- Application of special cryoprotective solutions
- Storage of embryos in liquid nitrogen tanks at –196°C
This process ensures embryos remain safely preserved for future fertility treatments.
How Long Can Frozen Embryos Be Stored?
According to legal regulations, embryos can generally be stored for up to 3 years.
After this period, storage may be extended with the written consent of the couple.
Throughout the storage period, embryos remain safely preserved in specialized laboratory
Frozen Embryo Transfer (FET) Process
When a couple decides to proceed with pregnancy, a Frozen Embryo Transfer (FET) cycle is planned.
The process usually involves the following steps:
- Preparation of the uterine lining using hormone therapy
- Thawing of the frozen embryo
- Transfer of the embryo into the uterus
The success of frozen embryo transfer depends on several factors, including:
- Maternal age
- Embryo quality
- Laboratory standards
In many fertility centers today, pregnancy rates achieved with frozen embryos are comparable to those achieved with fresh embryo transfers.
Advantages of Embryo Freezing in Cyprus
Embryo Freezing in Cyprus offers several important advantages for couples undergoing fertility treatment.
Key benefits include:
- No need for repeated ovarian stimulation
- Reduced physical and hormonal burden on the patient
- Financial advantages by avoiding additional stimulation cycles
- Flexibility for future family planning
- A new opportunity after unsuccessful IVF attempts
Additionally, surplus embryos obtained after IVF, egg donation, sperm donation, embryo donation, and genetically tested IVF treatments PGD / NGS can also be safely preserved for future use.
