A clinic in South Mumbai claims a 72% IVF success rate. A chain in Delhi says 68%. A Bangalore clinic says 75% for women under 35.

These numbers are not necessarily lies. But they are almost certainly not what you think they mean. And the gap between what those numbers suggest and what actually happens is where couples lose money, time, and emotional energy.

India has no mandatory, audited IVF success rate reporting. There is no equivalent of the UK's HFEA registry or the US's SART database where clinics must submit verified data in a standardised format. What this means in practice is that every clinic in India gets to define "success rate" however they want, measure it however they want, and present it however they want.

This article exposes the seven most common ways clinics inflate their numbers. More importantly, it tells you exactly what to ask to get the real picture.

Trick #1: Clinical Pregnancy Rate vs. Live Birth Rate

This is the most widespread and most impactful inflation.

Metric | What It Means | Typical Rate (Under 35)

Positive beta-hCG | Blood test positive 10-14 days after transfer | 50-60%

Clinical pregnancy | Gestational sac on ultrasound at 6 weeks | 40-50%

Live birth | A baby is born alive | 35-42%

The difference between clinical pregnancy rate and live birth rate is 10-15 percentage points. That gap represents miscarriages, ectopic pregnancies, and stillbirths.

When a clinic says "65% success rate," they are virtually always quoting clinical pregnancy rate — or sometimes even positive beta-hCG rate. If they were using live birth rate, the number would be closer to 45-50%.

Why clinics do this: It is not technically false. But it is deeply misleading when a patient hears "65% success" and thinks it means a 65% chance of taking a baby home.

What to ask: "Is your quoted success rate based on live births, clinical pregnancies, or positive pregnancy tests?" If they cannot specify, assume the most flattering definition.

Trick #2: Patient Selection Bias

This is the most powerful but least visible form of inflation.

Imagine two clinics:

  • Clinic A takes all patients, including women over 40, low ovarian reserve, failed cycles elsewhere, complex male factor cases.
  • Clinic B quietly discourages difficult cases — suggesting older patients "try naturally" or referring complex cases to other centres.

Clinic B will have dramatically better success rates without being better at IVF. They simply have an easier patient population.

How this plays out in India:

  • Some premium clinics in metro cities are known to discourage patients with AMH below 0.5 ng/mL or women over 42 from starting IVF — not always openly, but through subtle suggestions.
  • Clinics that specialise in "first-time IVF patients under 35" will have inherently better numbers than centres that handle the cases everyone else has given up on.
  • Some clinics recommend donor eggs very early for borderline cases. This improves their "own egg" success rate because difficult cases are moved into a separate (donor egg) category.

What to ask: "What percentage of your patients are over 38? What is your live birth rate specifically for women over 38 using their own eggs?" A clinic with a genuinely broad patient base will have these numbers ready.

Trick #3: Disappearing Cancelled Cycles

This is straightforward maths manipulation.

If a clinic starts 100 cycles but only 80 reach embryo transfer (the other 20 were cancelled due to poor response, failed fertilisation, or no viable embryos), reporting success "per transfer" instead of "per cycle started" automatically inflates the rate by 20%.

Metric | Calculation | Result

Per cycle started | 30 live births / 100 cycles started | 30%

Per embryo transfer | 30 live births / 80 transfers | 37.5%

Both numbers are "correct." But the per-transfer number hides the 20 women who went through stimulation, injections, monitoring, and emotional upheaval — and did not even make it to transfer.

Why this matters especially for older women: Cancellation rates increase significantly with age. At 40+, 25-35% of cycles may be cancelled. So the gap between "per cycle" and "per transfer" rates is largest for the patients who need the most honest data.

What to ask: "Do you report success per cycle started or per embryo transfer?" Then ask for both numbers.

Trick #4: Mixing Fresh and Frozen Transfer Data

Frozen embryo transfers (FET) from previously vitrified embryos often have success rates as good as — or better than — fresh transfers, because the best embryos are often the ones that survive freezing.

Some clinics combine all transfers (fresh + frozen) into a single success rate. If a patient had a failed fresh transfer but succeeded on a subsequent frozen transfer from the same cycle, the clinic can count the cycle as a success — even though the patient needed two transfer attempts.

Other clinics count each transfer separately, which can inflate the apparent number of successful outcomes relative to the number of patients.

The honest metric is: What percentage of patients who started an IVF cycle ultimately had a live birth from that cycle's embryos (fresh + frozen transfers combined)?

Trick #5: Excluding Add-On Costs from "Package" Success Claims

This is more about cost transparency than raw success rate inflation, but it feeds the same problem.

Clinics sometimes tie success rate claims to premium packages: "Our Platinum package has a 60% success rate!" But the Platinum package includes ICSI, blastocyst culture, PGT-A genetic testing, and assisted hatching — all of which are add-ons that cost ₹50,000-₹1.5 lakh on top of the base cycle.

The implication is that spending more improves your odds. In reality, some of these add-ons have limited evidence of benefit, and the higher success rate of the premium package often simply reflects the fact that patients who can afford it tend to be younger and healthier (selection bias again).

What to ask: "What is the success rate of your basic IVF cycle, without add-ons, for women in my age group?"

Trick #6: Small Sample Sizes Presented as Statistics

A new clinic does 30 cycles in its first year. 15 of those result in live births — a 50% success rate. They plaster this on their website.

With 30 cycles, the statistical confidence interval is enormous. The true underlying rate could be anywhere from 30% to 70%. But the marketing says 50%.

Well-established international registries require hundreds of cycles before considering data statistically meaningful. In India, a clinic with 30-50 cycles per year can claim percentages that would be meaningless to any statistician.

What to ask: "How many IVF cycles did you complete last year? How many were in my age group?" If the total is under 100 (or under 30 in your age group), treat any quoted success rate with extreme caution.

Trick #7: Outdated Data and Cherry-Picked Time Periods

If a clinic had a particularly good year in 2023 (perhaps they had an unusually young patient cohort that year, or a star embryologist who has since left), they may continue quoting 2023 numbers in 2026.

Some clinics also quote success rates from "selected cases" or "optimal responder" subgroups — essentially cherry-picking the patients who would have done well anywhere.

What to ask: "What year does your quoted success rate come from? Is it for all patients or selected patients?"

What Honest Reporting Looks Like

Here is what a clinic with nothing to hide would publish:

Metric | What They'd Report

Time period | Calendar year 2025 (most recent complete data)

Patient population | All patients, no exclusions

Success definition | Live birth rate

Denominator | Per cycle started (not per transfer)

Age stratification | Under 35, 35-37, 38-40, 41-42, 43+

Sample size | Number of cycles per age group

Cancellation rate | Percentage of cycles that did not reach transfer

Include frozen transfers | Cumulative live birth rate per cycle (fresh + subsequent FETs)

If a clinic provides data in this format, they are being honest with you. In India, as of 2026, almost no clinic voluntarily reports at this level of detail. The ART Act 2021 mandates reporting to the National Registry, but enforcement and public data access are still evolving.

The Five Questions That Cut Through Everything

Take these to your consultation. Write them down. A clinic that welcomes these questions is a clinic that respects you:

  1. 1"What is your live birth rate per cycle started for women aged [your bracket]?" — Not per transfer. Not clinical pregnancy rate. Live births per cycle started.
  2. 2"How many cycles in my age group did you do in the last 12 months?" — Anything under 30 makes the data statistically meaningless.
  3. 3"What percentage of cycles in my age group were cancelled before transfer?" — This tells you the denominator they are hiding.
  4. 4"Can I see your data reported to the National ART Registry (ICMR)?" — Under the ART Act, clinics are required to report. Asking for this data is your right.
  5. 5"Do your success rates include donor egg cycles, or are those reported separately?" — Donor egg cycles have much higher success rates. Mixing them in inflates the overall number.

If a clinic becomes defensive, evasive, or says "our success rates are confidential" — you have your answer. Walk out.

Questions to Ask Your Doctor

Beyond the five above, here are additional questions for your consultation:

  • "How do you define a successful cycle in your clinic?"
  • "What is the average number of cycles your patients in my age group need before a live birth?"
  • "Do you have any third-party audited outcome data?"
  • "What is your multiple pregnancy rate?" (A high multiple pregnancy rate may indicate routine transfer of multiple embryos to boost pregnancy numbers — at the cost of patient safety.)
  • "If my cycle is cancelled, what do I pay?"

What You Can Do Right Now

  1. 1Do not compare clinics on a single number. A "65% success rate" at one clinic and a "45% success rate" at another might actually reflect the same clinical quality — the difference could be entirely in how they measure and report.
  2. 2Look for clinics affiliated with ESHRE or FOGSI that participate in voluntary outcome reporting programmes.
  3. 3Check the National ART & Surrogacy Registry (set up under the ART Act 2021) for registered clinics. While enforcement is still evolving, registration itself is a baseline indicator.
  4. 4Talk to other patients. Online IVF support groups, including Indian-specific groups on Facebook and Reddit, can give you real patient experiences that no statistic captures.
  5. 5Trust the clinic that gives you honest odds — even if those odds are lower than the clinic down the road. A doctor who tells you "your chances are 20% per cycle" is more likely to be your partner in this journey than one who promises 60% and hopes you will not ask questions.
