For many couples struggling with infertility, Frozen Embryo Transfer (FET) represents a ray of hope—a chance to achieve the dream of parenthood without undergoing repeated, extensive IVF cycles. Modern reproductive technology has made it possible to preserve embryos for future use, giving couples the flexibility and time to plan their pregnancy.
In this blog, we’ll explore everything you need to know about FET—what it is, how it works, its benefits, tips to improve success rates, and the cost involved. Whether you are considering FET as your next step or simply curious about the process, this guide will help you make an informed choice.
What is a Frozen Embryo Transfer?
Frozen Embryo Transfer is a part of assisted reproductive technology (ART) where embryos created during an IVF cycle are frozen (cryopreserved) for future use. Instead of transferring fresh embryos immediately after fertilization, they are preserved in liquid nitrogen at an extremely low temperature of -196 °C. These embryos can later be thawed and transferred into the uterus when conditions are most favorable for pregnancy.
FET is especially beneficial for women who:
-
Want to delay pregnancy after an IVF cycle
-
Need to recover from ovarian stimulation before attempting embryo transfer
-
Wish to space pregnancies for a second child
-
Prefer transferring embryos when the uterus is hormonally optimized
The beauty of this process is that it gives you control and flexibility, making family planning less stressful and more personalized.
The Journey of an Embryo – From Fertilization to Freezing
The FET process starts just like a conventional IVF cycle:
-
Ovarian Stimulation: The prospective mother’s ovaries are stimulated with hormones to produce multiple mature eggs.
-
Egg Retrieval (Ovum Pick-Up): The eggs are collected through a minor surgical procedure known as follicular puncture.
-
Fertilization in the Lab: The retrieved eggs are fertilized with the husband’s or donor sperm, creating embryos.
-
Freezing the Embryos: While one or more embryos may be transferred fresh, the remaining healthy embryos are frozen and stored for future use.
What Happens to Surplus Frozen Embryos?
The fate of unused embryos varies depending on the couple’s choice. Common options include:
-
Cryopreservation for Future Use – The most common option, allowing for additional pregnancy attempts without undergoing a full IVF cycle again.
-
Embryo Donation – With consent, spare embryos may be donated to other couples struggling with infertility.
-
Research Donations – Some couples choose to donate embryos for stem cell research (with proper consent).
-
Embryo Discarding – In some cases, couples may choose to have embryos discarded after giving written consent.
What is Embryo Transfer Technology (ETT)?
Embryo Transfer Technology is a specialized reproductive technique where embryos are transferred to the uterus after fertilization. The embryos can be fresh or frozen. For FET, embryos are thawed carefully to preserve their viability before being implanted into the uterus.
The ultimate goal of ETT is to create a favorable uterine environment for implantation, ensuring that the embryo successfully attaches and develops into a healthy pregnancy.
4 Tips to Improve Frozen Embryo Transfer Success Rates
Every woman’s body responds differently to treatment, but there are ways to increase the chances of implantation. Here are expert-recommended tips:
1. Choose a Skilled Embryologist and Fertility Specialist
The expertise of your fertility team plays a major role in the success of FET. The process of thawing and transferring embryos is delicate and requires experienced hands. Specialists at reputed fertility centers like SCI IVF Hospital are trained in advanced embryo-handling techniques to maximize success rates.
2. Never Skip Pre-IVF Tests
Comprehensive pre-transfer testing is crucial. Tests may include:
-
Transvaginal ultrasound of the uterus, ovaries, and fallopian tubes
-
Hormonal profile assessment
-
Semen analysis (if required)
These tests help doctors identify any underlying issues that might hinder implantation.
3. Maintain a Healthy Diet & Lifestyle
There’s no special “implantation diet,” but a healthy, balanced diet supports overall reproductive health. Include:
-
Fresh fruits and vegetables
-
Whole grains and lean proteins
-
Omega-3-rich foods like nuts and seeds
Avoid smoking, alcohol, and excessive caffeine.
4. Take Folic Acid Supplements
A folic acid supplement (400-600 mcg daily) is recommended for at least three months before the FET cycle. It not only supports early fetal development but also reduces the risk of neural tube defects.
Advantages of Frozen Embryo Transfer
FET offers several benefits over fresh embryo transfer, including:
-
Higher Pregnancy Success Rates – The uterine lining is often more receptive when not affected by ovarian stimulation drugs.
-
Fewer IVF Cycles – One ovarian stimulation can lead to multiple embryo transfers over time.
-
Flexibility and Convenience – Couples can plan pregnancy according to their personal and health priorities.
-
Safer for Women with Ovarian Hyperstimulation Syndrome (OHSS) – Doctors can postpone embryo transfer until the body recovers.
-
Cost-Effective in the Long Run – Once embryos are frozen, subsequent transfers are significantly less expensive than undergoing another fresh IVF cycle.
Cost of Frozen Embryo Transfer in India
The cost of FET is relatively affordable compared to undergoing an entire IVF cycle again. On average, the cost ranges around:
-
₹75,000 (approximately) – This includes the thawing process, embryo transfer, and basic medications.
-
Additional IVF Stage Costs – If required, medication or additional hormonal support may incur extra charges.
It’s essential to discuss the cost breakdown with your fertility clinic to avoid unexpected expenses.
Emotional Journey – Coping with the Waiting Period
One of the toughest parts of FET is the two-week wait after the transfer, as couples anxiously hope for positive pregnancy results. During this period:
-
Stay relaxed and avoid stress
-
Engage in light activities like reading or meditation
-
Avoid heavy workouts or strenuous physical exertion
-
Follow all post-transfer instructions provided by your doctor
Remember, patience and a calm mindset can positively impact your emotional well-being during this crucial time.
