What is Frozen Embryo Transfer?
Frozen Embryo Transfer (FET) is an assisted reproductive technology where previously frozen embryos from in vitro fertilization (IVF) are thawed and transferred into a woman’s prepared uterus. By preserving and utilizing extra embryos from earlier IVF cycles, this technique raises the likelihood of a healthy pregnancy.
Here is a basic step-by-step review of frozen embryo transfer to give a general understanding of the procedure:
- Initial Assessment: Your health and medical history are reviewed by the medical team before FET.
- Hormonal Preparation: To control your menstrual cycle and provide the ideal uterine environment for embryo implantation, you may use medication.
- Embryo Thawing: To guarantee their viability, the frozen embryos are gradually thawed.>
- Endometrial Thickness Monitoring: Hormone therapy is utilized to promote uterine lining growth. It is possible to monitor the thickness with ultrasound scanning.
- Administration of Progesterone: To prepare the uterine lining for embryo implantation, progesterone supplements are frequently recommended.
- Timing: The embryo’s readiness and the uterine lining’s development are the main factors that determine when to transfer an embryo.
- Embryo Transfer: A tiny catheter is used to insert a chosen embryo into the uterus. This is a painless and reasonably short process.
- Post-Transfer Monitoring: You may be told to rest for a short while following the transfer. There may be further hormonal support available.
- Pregnancy Test: To determine whether an embryo transfer has resulted in pregnancy, a blood test is typically conducted 10–14 days later.
