Frozen Embryo Transfer (FET)
Why Choose FET?
FET provides both flexibility and reassurance for patients planning their fertility journey. It may be recommended if you:
Have embryos frozen from a previous IVF or ICSI cycle
Wish to delay implantation until your body is ready
Are undergoing genetic testing (PGT/NGS) before transfer
Prefer additional time for recovery or international travel planning
How Does FET Work?
The FET process is carefully planned to optimize the chance of successful implantation.
- Natural Cycle: FET can be performed in a natural cycle, where the woman’s menstrual cycle is monitored, and the transfer is timed with ovulation.
- Hormone Replacement Therapy (HRT) Cycle: More commonly, the endometrium (uterine lining) is prepared with estrogen and progesterone to ensure it reaches the optimal stage for embryo implantation.
- Ultrasound Scans: Used to monitor the thickness of the endometrial lining and, in natural cycles, to observe follicle development.
- Blood Tests: Hormone levels may be checked to confirm the ideal environment for implantation.
- Thawing the embryo: The frozen embryo is carefully thawed in a laboratory. The success of this step depends on the quality of the cryopreservation process.
- Embryo Transfer: The thawed embryo is loaded into a catheter and transferred into the uterus. This quick, usually painless procedure is performed under ultrasound guidance.
- Luteal Phase Support: Progesterone supplements are typically provided to support the endometrium and aid embryo implantation.
- Rest and Activity: Patients are generally advised to rest for a couple of days but can typically resume normal activities soon after.
- Pregnancy Test: A blood test is conducted about 10–14 days after the transfer to confirm pregnancy.
- Embryo Quality: Higher-quality embryos are more likely to implant and develop into a successful pregnancy.
- Endometrial Thickness: An endometrial lining optimally prepared (usually 8-14 mm thick) is ideal for implantation.
Age: The woman’s age at embryo freezing can influence success rates, with younger age at freezing generally associated with higher success rates.
Clinic Protocols: Different clinics may have varying success rates depending on their specific protocols and technologies.
- Flexibility: Allows for genetic testing of embryos and for scheduling the transfer when the recipient’s body is most receptive.
- Higher Success Rates: Some studies suggest that FET cycles have slightly higher success rates than fresh transfers, as the body has more time to recover from ovarian stimulation.
