The FET Procedure: Step by Step
The FET procedure in IVF typically involves several carefully coordinated steps:
1. Preparation Phase
- Hormonal evaluation to determine optimal timing
- Endometrial lining preparation through hormone therapy or in a natural cycle
- Regular monitoring via ultrasound and blood tests
2. Embryo Thawing
- Selection of the highest quality frozen embryos
- Careful thawing using specialised protocols
- Assessment of post-thaw embryo quality
3. Transfer Process
- Precise timing coordination with endometrial receptivity
- Ultrasound-guided transfer procedure
- Post-transfer care instructions
Benefits of Frozen Embryo Transfer
Advantages of Frozen Embryo Transfer (FET) make it a preferred method in modern fertility clinics:
- Improved Timing: Patients may, as a result of embryo freezing and Egg Freezing, pause and plan transfer at the most convenient time for their emotional and physical well-being.
- Higher Success Rates: With advancements in freezing techniques, the success rates of FET in IVF are comparable to, if not better than, fresh transfers.
- Lower Risks: FET reduces the chances of ovarian hyperstimulation syndrome (OHSS), a complication from fertility medications.
FET vs. Fresh Embryo Transfer
While fresh embryo transfer was once the standard, FET vs. fresh embryo transfer debates often highlight the former’s superiority:
- FET Advantages: Offers flexibility in planning and eliminates the immediate hormonal stress post-egg retrieval.
- Fresh Transfer: This can be quicker but may not always align with optimal uterine conditions, potentially lowering implantation success.
Success Rates of FET in IVF
The success rates of FET in IVF have soared thanks to advances in embryo freezing and Egg Freezing and storage methods. Studies indicate that FET success often matches or even surpasses fresh transfers, particularly in cases where the uterine environment is optimised. Factors such as embryo quality, maternal age, and uterine health significantly influence these outcomes.
The success rates of FET in IVF depend on various factors, including age of the woman at egg retrieval
Key factors affecting outcomes include:
- Embryo quality before freezing
- Laboratory techniques used
- Endometrial preparation
- Overall reproductive health
Freezing Embryos for IVF: How It Works
The actual process of freezing embryos is called ‘vitrification’ and involves freezing them in a short period so that ice crystals do not form and destroy the cells. The currently frozen embryos are actually kept in very specialised facilities that will ensure for years viability.
The timing of frozen embryo transfer is crucial. Transfer can occur after a few months or several years after collection, with little difference in chances of success.
Potential Risks and Considerations
While FET is generally safe, awareness of the potential risks of frozen embryo transfer is important:
- Minimal risk of embryo damage during freeze-thaw process
- Possibility of multiple pregnancies
- Standard risks associated with any fertility treatment
- Emotional and physical preparation requirements
Cost of Frozen Embryo Transfer
Usually, the cost of the frozen embryo transfer in India would range from ₹30,000 to ₹60,000 depending upon the per cycle, excluding the embryo freezing and storage charges. While an investment, many find the flexibility and increased chances of success justify the expense.
Factors Affecting FET Outcomes
Several variables impact the success of FET:
- Embryo Quality: Higher-grade embryos show improved survival and implantation rates.
- Uterine Health: Good quality endometrium-thick and receptive-endometrial lining is very crucial for implantation.
- Lifestyle Choices: Healthy weight balanced dietary intake, and stress management greatly improve the outcomes.
Conclusion

Frequently Asked Questions (FAQs)
- How does the FET procedure exactly work?
FET involves preparation of the endometrial lining through hormone therapy or naturally, thawing of the frozen embryos with advanced techniques, and transfer of the embryo to the uterus under ultrasound guidance. Regular monitoring ensures the timing that would be appropriate for implantation.
- What do you gain from selecting FET over fresh embryo transfer?
Among the benefits is that FET gives patients flexibility so that they can plan exactly when they feel ready to have an embryo transfer. Furthermore, it diminishes risks inherent in ovarian hyperstimulation syndrome (OHSS) and usually meets other prerequisites of a better uterine environment.
- Is embryo quality lost by freezing/thawing the embryos?
Due to advanced vitrification techniques, the harm imposed by freezing or thawing is minimal. The viability and implantation potential of high-quality embryos are often expected to be maintained following thawing.
- How successful is FET for women of different age groups?
Younger women often end up with more successful FET cycles. In fact, different factors, like the quality of the embryo and uterine health, also matter.
- What are some factors that can influence success in a FET cycle?
Key factors essential for the success of a FET cycle are the quality of the frozen embryo, tone of the endometrial lining, extrinsic reproductive status, and a healthy lifestyle.
