Frozen Embryo Transfer (FET) is a procedure where previously cryopreserved embryos from an IVF cycle are carefully thawed and transferred to the woman’s uterus. FET has become one of the most commonly performed procedures in modern IVF, with research showing comparable or even superior outcomes to fresh embryo transfers in many cases. Whether you have surplus frozen embryos from a previous cycle, underwent a freeze-all strategy, or are using PGT-tested embryos, this guide covers everything about FET cost, procedure, and success rates in India in 2026.
What Is Frozen Embryo Transfer (FET)?
A Frozen Embryo Transfer is a procedure in which embryos that were previously created during an IVF cycle, vitrified (flash-frozen), and stored in liquid nitrogen are thawed and transferred to the woman’s uterus in a subsequent cycle. The key advantage of FET is that it separates the egg retrieval/fertilization process from the embryo transfer, allowing the uterine lining to be prepared under optimal conditions without the hormonal effects of ovarian stimulation.
Modern vitrification techniques have made FET extremely reliable, with embryo survival rates of 95–99% after thawing. This has led many fertility specialists to adopt a “freeze-all” strategy — freezing all embryos and performing FET in a later cycle — as their standard approach, especially when PGT is involved, when OHSS risk is high, or when progesterone levels are elevated during stimulation.
FET Cost in India (2026)
The cost of a frozen embryo transfer in India ranges from ₹45,000 to ₹95,000 per cycle. This is significantly less than a full IVF cycle because it does not involve ovarian stimulation or egg retrieval — the embryos already exist in frozen storage.
| Component | Estimated Cost (₹) |
|---|---|
| Pre-FET Consultation & Assessment | ₹1,000 – ₹3,000 |
| Endometrial Preparation Medications (Estrogen + Progesterone) | ₹5,000 – ₹15,000 |
| Monitoring Scans & Blood Tests (3–5 visits) | ₹5,000 – ₹12,000 |
| Embryo Thawing & Assessment | ₹10,000 – ₹20,000 |
| Embryo Transfer Procedure | ₹15,000 – ₹35,000 |
| Post-Transfer Progesterone Support (2–3 months) | ₹5,000 – ₹15,000 |
| Pregnancy Test (Beta-hCG Blood Test) | ₹500 – ₹1,500 |
| Total FET Cost per Cycle | ₹45,000 – ₹95,000 |
Important clarification: FET cost does NOT include the original embryo freezing cost or annual storage fees — those are separate charges from the initial IVF cycle. Always ask your clinic for an itemized breakdown that separates these costs clearly.
Detailed Cost Breakdown
1. Pre-FET Consultation (₹1,000 – ₹3,000)
Before starting the FET cycle, you’ll meet your fertility specialist to review your frozen embryo inventory, discuss the transfer protocol, and plan the cycle timeline. If you haven’t had a recent uterine assessment, a baseline ultrasound may be performed.
2. Endometrial Preparation Medications (₹5,000 – ₹15,000)
The uterine lining (endometrium) must be optimally thick and receptive for the embryo to implant. In a medicated FET protocol, estrogen tablets or patches are started on day 2–3 of your period to thicken the lining, followed by progesterone (vaginal pessaries, injections, or oral tablets) to transform the lining into a receptive state. Medication costs depend on the type and brand used.
3. Monitoring Scans & Blood Tests (₹5,000 – ₹12,000)
During endometrial preparation, you’ll have 3–5 monitoring visits to check endometrial thickness (target: ≥7–8mm) and pattern via transvaginal ultrasound, and hormone levels via blood tests. These visits ensure the lining is ready before scheduling the transfer.
4. Embryo Thawing (₹10,000 – ₹20,000)
On the scheduled transfer day (or the day before), the selected frozen embryo(s) are carefully thawed by the embryologist. The thawing process involves gradually removing cryoprotectants and rehydrating the embryo. The embryo is then assessed under a microscope to confirm it has survived the freeze-thaw process and is viable for transfer. Vitrified embryos have a 95–99% survival rate.
5. Embryo Transfer Procedure (₹15,000 – ₹35,000)
This is a short, painless outpatient procedure — similar to a Pap smear. Under ultrasound guidance, a thin, soft catheter is passed through the cervix into the uterus, and the embryo is gently deposited in the optimal position. The entire procedure takes about 5–15 minutes. No anaesthesia is required in most cases. You can go home shortly afterward.
6. Post-Transfer Medications (₹5,000 – ₹15,000)
After transfer, you’ll continue progesterone supplementation for 8–12 weeks (until the placenta takes over hormone production). Some doctors also prescribe blood thinners, folic acid, or other supportive medications based on individual needs.
Optional Add-Ons That May Increase FET Cost
Assisted Hatching (₹10,000 – ₹20,000): A laser is used to thin the embryo’s outer shell to aid implantation. Recommended for women over 37 or frozen embryos with a thickened zona.
EmbryoGlue (₹5,000 – ₹10,000): A hyaluronan-enriched transfer medium that may improve implantation rates.
Endometrial Receptivity Analysis – ERA (₹25,000 – ₹40,000): A biopsy test to determine the optimal timing for embryo transfer (the “window of implantation”).

FET Protocols – Medicated vs Natural Cycle
Medicated (Hormone Replacement) FET – Most Common
In a medicated FET, exogenous hormones (estrogen and progesterone) are used to prepare the endometrium. This protocol offers precise control over timing, is not dependent on natural ovulation, and is the most widely used approach. It is ideal for women with irregular cycles, PCOS, or anovulation.
Natural Cycle FET
In a natural FET, the woman’s own hormonal cycle prepares the endometrium. The doctor monitors natural follicle development and ovulation timing, and the transfer is scheduled accordingly. This protocol uses fewer medications but requires more frequent monitoring and is dependent on regular ovulation. It may be preferred by women who want to minimize hormone exposure.
Modified Natural Cycle FET
A hybrid approach where the natural cycle is monitored but a trigger shot (hCG) is given to precisely time ovulation, followed by progesterone supplementation. This combines the benefits of a natural approach with better timing control.
| Factor | Medicated FET | Natural Cycle FET |
|---|---|---|
| Medication cost | ₹5,000 – ₹15,000 | ₹1,000 – ₹5,000 |
| Monitoring visits | 3–4 visits | 5–7 visits |
| Timing flexibility | High (doctor-controlled) | Low (depends on natural cycle) |
| Best for | Irregular cycles, PCOS | Regular cycles, hormone-averse |
| Success rates | Comparable | Comparable |
FET Procedure – Step-by-Step Guide
Step 1: Pre-FET Assessment (Week 1)
Baseline ultrasound on Day 2–3 of your menstrual period to check that the uterus is clear and there are no cysts or abnormalities. Blood tests may be ordered to check hormone levels.
Step 2: Endometrial Preparation (Weeks 1–3)
Start estrogen medication (tablets, patches, or vaginal route) to grow the uterine lining. Monitoring scans are performed every 3–5 days to assess endometrial thickness and pattern. Target thickness: ≥7–8mm with a triple-line (trilaminar) pattern.
Step 3: Progesterone Initiation (Day of Lining Readiness)
Once the endometrium is ready, progesterone supplementation begins (vaginal pessaries, intramuscular injections, or oral micronized progesterone). The progesterone transforms the thickened endometrium into a receptive state. Embryo transfer is scheduled based on the embryo’s developmental stage — typically 5 days of progesterone exposure for a Day 5 blastocyst.
Step 4: Embryo Thawing (Transfer Day or Day Before)
The embryologist thaws the selected embryo(s) using a controlled warming process. The embryo is assessed under a microscope for cell survival, re-expansion (for blastocysts), and viability. If the embryo has survived well (95–99% do with vitrification), it’s ready for transfer.
Step 5: Embryo Transfer (Transfer Day)
You arrive at the clinic with a comfortably full bladder (aids ultrasound visualization). The doctor uses a thin, soft catheter to pass through the cervix and deposits the embryo in the optimal uterine position under abdominal ultrasound guidance. The procedure takes 5–15 minutes and is virtually painless. You rest for 15–30 minutes before going home.
Step 6: Post-Transfer Care & Two-Week Wait
Continue all prescribed medications (progesterone, estrogen, and any supplements). Resume normal daily activities — bed rest is NOT required or recommended. Avoid heavy exercise, hot baths, and alcohol. The “two-week wait” (TWW) between transfer and pregnancy test can be emotionally challenging — seek support from your partner, counsellor, or support groups.
Step 7: Pregnancy Test (10–14 Days Post-Transfer)
A blood test for beta-hCG confirms whether implantation has occurred. If positive, repeat beta-hCG testing and an early ultrasound (at 6–7 weeks) confirm a viable pregnancy. If negative, your doctor will discuss next steps, including the possibility of another FET cycle.
Who Needs FET?
Couples with frozen embryos from previous IVF: If you have surplus frozen embryos from a previous cycle, FET allows you to attempt pregnancy without repeating the full IVF process.
Freeze-all strategy patients: When all embryos are frozen (due to OHSS risk, elevated progesterone, or PGT), FET is the planned next step.
PGT patients: Embryos biopsied for genetic testing are frozen while awaiting results. Only genetically normal embryos are transferred via FET.
Failed fresh transfer: If a fresh embryo transfer was unsuccessful but frozen embryos remain, FET is the logical next step.
Fertility preservation patients: Women who froze embryos before cancer treatment or for elective reasons use FET when ready to conceive.
Donor egg/surrogacy cycles: Embryos created with donor eggs are often frozen and transferred to the recipient or surrogate in a separate FET cycle.
FET Success Rates
| Age at Embryo Creation | Embryo Survival (Thaw) | Implantation Rate | Live Birth Rate (per FET) |
|---|---|---|---|
| Under 30 | 97–99% | 55–65% | 50–60% |
| 30–34 | 95–99% | 45–55% | 45–55% |
| 35–37 | 95–98% | 35–50% | 35–45% |
| 38–40 | 93–97% | 25–40% | 25–35% |
| Over 40 | 90–95% | 15–30% | 15–25% |
Key point: What matters most is the age at which the embryos were created, not the age at the time of transfer. A 40-year-old woman transferring embryos she froze at 32 retains the success rates of a 32-year-old.
Fresh Transfer vs Frozen Embryo Transfer
| Factor | Fresh Transfer | Frozen Transfer (FET) |
|---|---|---|
| Timing | Same cycle as egg retrieval | Separate cycle (weeks/months later) |
| Uterine environment | May be affected by stimulation hormones | Optimally prepared, natural-like |
| OHSS risk | Higher (if stimulated uterus) | None (no stimulation) |
| Allows PGT | No (no time for results) | Yes (embryos frozen while tested) |
| Success rates | 35–50% | 40–60% |
| Cost | Included in IVF cycle | ₹45,000 – ₹95,000 additional |
| Flexibility | Tied to IVF cycle timeline | Flexible scheduling |
Many leading fertility centres worldwide are moving toward a “freeze-all” approach, where all embryos are frozen and transferred in a subsequent FET cycle. This allows the uterine lining to recover from the stimulation phase and is associated with lower OHSS rates, lower ectopic pregnancy rates, and in some studies, higher live birth rates.
Benefits & Risks of FET
Benefits
Optimal uterine preparation: The endometrium can be prepared under controlled conditions without the hormonal effects of ovarian stimulation, creating a more receptive environment for implantation.
No egg retrieval needed: FET avoids the physical discomfort and risks of repeated ovarian stimulation and egg retrieval procedures.
Lower cost than full IVF: At ₹45,000–₹95,000, FET is significantly cheaper than a new IVF cycle.
Flexible timing: FET can be scheduled at a time that’s convenient for you, without being tied to the stimulation cycle timeline.
Enables PGT: FET is essential for transferring PGT-tested embryos, as results take 1–3 weeks.
Reduced OHSS risk: By separating stimulation from transfer, FET eliminates the risk of OHSS worsening during early pregnancy.
Comparable or better outcomes: Multiple studies show FET success rates are equal to or higher than fresh transfer rates.
Risks & Considerations
Not all embryos survive thawing: While vitrification has a 95–99% survival rate, 1–5% of embryos may not survive the thaw process.
Additional cycle needed: FET requires a separate cycle (3–4 weeks), adding time to the overall IVF journey.
Medication dependency: In medicated FET, you’ll take hormones for 8–12 weeks if pregnancy occurs.
Extra cost: The FET cycle is an additional cost beyond the original IVF cycle.
Emotional wait: The gap between egg retrieval and FET can be emotionally challenging for some couples.
Tips to Improve FET Success
Follow medication instructions precisely: Correct timing and dosage of estrogen and progesterone are critical for endometrial receptivity. Don’t miss doses.
Maintain a healthy lifestyle: Balanced nutrition, adequate sleep, moderate exercise, and stress management all support a healthy uterine environment.
Avoid harmful substances: No smoking, alcohol, excessive caffeine, or recreational drugs during the FET cycle.
Consider acupuncture: Some studies suggest acupuncture around the time of transfer may improve implantation rates, though evidence is mixed.
Stay hydrated: Adequate water intake supports uterine blood flow and endometrial health.
Trust the process: After transfer, resume normal activities. Bed rest does NOT improve outcomes — in fact, gentle movement is better.
Seek emotional support: The two-week wait is stressful. Connect with your partner, support groups, or a counsellor.
Frequently Asked Questions (FAQs)
What is the cost of FET in India?
FET costs ₹45,000–₹95,000 per cycle in India. This covers pre-FET assessment, endometrial preparation medications, monitoring scans, embryo thawing, the transfer procedure, and post-transfer progesterone support.
Is FET better than fresh embryo transfer?
In many cases, yes. FET allows the uterine lining to be prepared under optimal conditions, reduces OHSS risk, and enables PGT. Studies show comparable or slightly better success rates with FET, particularly with the freeze-all approach.
What is the success rate of FET?
FET success rates range from 40–60% per transfer for women under 35. The key factor is the woman’s age at the time the embryos were created, not her age at transfer. Vitrified embryos have a 95–99% survival rate after thawing.
How long does the FET cycle take?
A FET cycle typically takes 3–4 weeks from the start of endometrial preparation to embryo transfer. Add 2 more weeks for the pregnancy test. Total: about 5–6 weeks from start to result.
How many FET cycles can I do?
There is no fixed medical limit. You can do as many FET cycles as you have frozen embryos available. Each cycle requires a fresh endometrial preparation phase. If frozen embryos run out, a new IVF cycle is needed to create more.
Is FET painful?
FET is generally painless and does not require anaesthesia. The embryo transfer procedure is similar to a Pap smear — a thin, soft catheter is passed through the cervix to deposit the embryo. Most women feel only mild pressure or light cramping. The entire procedure takes 5–15 minutes.
Do I need bed rest after FET?
No. Multiple studies have confirmed that bed rest after embryo transfer does NOT improve success rates. In fact, gentle normal activity and movement are recommended. Avoid only heavy exercise, hot baths, and strenuous activity for 48 hours.
Can I transfer embryos to a different clinic?
Yes, frozen embryos can be safely transported between clinics using specialized cryogenic shipping containers. Both clinics coordinate the transfer logistics. Transportation costs typically range from ₹10,000–₹30,000.
What if the FET fails?
If the first FET doesn’t result in pregnancy, your doctor will review possible causes and may adjust the protocol for the next attempt — such as changing the endometrial preparation regimen, adding assisted hatching, or performing an ERA test. If you have more frozen embryos, another FET can be attempted.
