Introduction
One of the first questions every patient asks when considering IVF — whether at home or abroad — is: “What are my actual chances?”
The answer is not simple. IVF success rates vary enormously depending on your specific circumstances. A 32-year-old with unexplained infertility on her first cycle has very different odds from a 42-year-old with low AMH who has had three previous failed cycles. Quoting a single “clinic success rate” without accounting for these individual factors is meaningless — and often misleading.
This guide explains exactly how IVF success rates are calculated, what factors affect your personal chances, and what you can realistically expect from treatment at a verified clinic in India.
How IVF Success Rates Are Calculated — and Why Most Quoted Figures Are Misleading
Before looking at numbers, it is important to understand what “success rate” actually means — because clinics quote it in different ways that produce very different figures.
Clinical pregnancy rate per embryo transfer — the most commonly quoted figure. Measures pregnancies confirmed by ultrasound at 6–8 weeks per embryo transfer procedure. This is a relatively generous measure because some of these pregnancies will end in miscarriage before a baby is born.
Live birth rate per embryo transfer — the most honest and meaningful figure. Measures actual babies born per transfer. This is typically 8–12% lower than the clinical pregnancy rate. Always ask for this figure.
Live birth rate per cycle started — the most conservative figure. Accounts for cycles that are cancelled before transfer due to poor response. This is the lowest number and the most honest representation of your actual chances when you start a cycle.
When comparing clinics — whether in India or anywhere else — always ask for live birth rate per cycle started. Any clinic unwilling to provide this figure should be treated with caution.
IVF Success Rates in India by Age Group
Age is the single most important factor in IVF success because it directly affects egg quality. Here are the clinical pregnancy rates per transfer at India’s top NABH and JCI accredited clinics in 2026:
| Age Group | Clinical Pregnancy Rate | Live Birth Rate |
|---|---|---|
| Under 35 | 65–72% | 56–62% |
| 35–37 | 60–66% | 52–57% |
| 38–40 | 48–56% | 42–48% |
| 41–43 | 36–44% | 31–38% |
| Over 43 | 24–32% | 20–27% |
| Donor Egg IVF (all ages) | 66–76% | 57–65% |
These figures reflect aggregate data from Fertibridge verified partner clinics and should be used as a guide rather than a guarantee. Individual outcomes vary based on additional factors covered below.
The key insight from this table: The dramatic difference between donor egg IVF and own egg IVF for women over 40 explains why donor egg IVF is so commonly recommended for patients in this age group. The eggs come from a young screened donor — so age of the egg, not the uterus, is the primary success driver.
Factors That Affect Your Personal IVF Success Rate
Beyond age, several other factors significantly influence your individual success probability:
Your Diagnosis
PCOS (Polycystic Ovarian Syndrome) — Generally a positive factor. PCOS patients typically produce a good number of eggs and respond well to stimulation with careful monitoring. Success rates are broadly in line with or slightly above the age-average. OHSS risk requires careful monitoring.
Low AMH / Poor Ovarian Reserve — Significantly negative factor with own egg IVF. Low AMH means fewer eggs retrieved per cycle, reducing the number of embryos available for transfer. This substantially lowers success rates. Donor egg IVF is frequently recommended and achieves dramatically higher success rates for patients with low AMH.
Male Factor Infertility — Addressable with ICSI (Intracytoplasmic Sperm Injection). ICSI involves injecting a single sperm directly into each egg, bypassing fertilisation barriers caused by poor sperm quality or quantity. ICSI adds approximately $400–$600 to cycle cost but significantly improves fertilisation rates for male factor patients.
Endometriosis — Moderate negative factor. Endometriosis can affect egg quality, ovarian reserve, and implantation. Success rates are typically 8–12% lower than the age average. Clinics with specialist endometriosis expertise and experience in surgical management are strongly recommended.
Blocked Tubes — Direct impact on natural conception but IVF bypasses the tubes entirely. Success rates for tubal factor patients are close to the age average for IVF — the tubes are not involved in the IVF process.
Unexplained Infertility — Success rates are broadly at the age average. Unexplained infertility can sometimes be resolved by the more controlled environment of IVF itself.
Recurrent Implantation Failure — Significant negative factor. Patients with 2 or more failed transfers warrant thorough investigation including endometrial receptivity testing, immune panel, and chromosomal testing of embryos (PGT-A). Choose a clinic with a dedicated recurrent implantation failure protocol.
Previous IVF History
First cycle — Highest success rates. There is no negative modifier from previous attempts and you benefit from a fresh start with a new protocol.
One previous failed cycle — Modest negative modifier. A previous failure provides useful information about your response to stimulation and allows protocol adjustments. Success rates remain strong.
Two or more failed cycles — More significant negative modifier, but certainly not without hope. Each failed cycle should inform a protocol review. Many patients who failed multiple cycles elsewhere achieve success in India with modified approaches or specialist expertise.
Previous chemical pregnancy or miscarriage — Partial positive indicator. A chemical pregnancy confirms successful fertilisation and implantation occurred. Miscarriage history may suggest chromosomal issues that PGT testing can address.
Treatment Type
Standard IVF — Baseline success rates as shown in the age table above.
IVF with ICSI — Similar to standard IVF for most patients; strongly recommended for male factor infertility where it significantly improves fertilisation rates.
Donor Egg IVF — Highest success rates across all age groups. Because egg quality is determined by the donor’s age rather than the recipient’s, success rates remain consistently high even for recipients over 40.
Frozen Embryo Transfer (FET) — Success rates comparable to fresh transfer in most cases. Some studies suggest FET may achieve slightly higher implantation rates due to improved endometrial preparation.
IVF with PGT-A (Preimplantation Genetic Testing) — PGT tests embryos for chromosomal abnormalities before transfer. Per-transfer success rates are higher because only chromosomally normal embryos are transferred. Particularly recommended for patients over 38, recurrent miscarriage, or recurrent implantation failure.
Why India’s Success Rates Are Comparable to Western Clinics
A common concern among international patients is whether India’s IVF success rates are genuinely comparable to those in the USA or UK. The evidence strongly suggests they are — at accredited clinics.
Accreditation standards are identical. JCI (Joint Commission International) accreditation certifies hospitals to exactly the same standards whether in Delhi or New York. A JCI accredited clinic in India operates to the same quality framework as a JCI accredited clinic in the USA.
Laboratory technology is the same. India’s top IVF laboratories use the same embryology equipment as Western clinics — time-lapse incubation, vitrification for embryo freezing, and advanced PGT technology are all available at leading Indian centres.
Doctors trained internationally. Many of India’s top IVF specialists trained at institutions in the UK, USA, and Europe. Their clinical training is equivalent to their Western peers.
High volume builds expertise. India’s leading IVF centres perform significantly higher cycle volumes than most Western clinics — volume builds embryologist and clinical expertise over time.
The cost difference between India and Western countries is not driven by lower clinical standards. It is driven by lower operating costs, lower regulatory overheads, and currency differences.
How to Use the Fertibridge IVF Success Rate Calculator
Our free success rate tool gives you a personalised estimate based on your specific situation in under 2 minutes. Here is what to enter:
Your age — select your age bracket from the dropdown. Age is the most heavily weighted factor in the calculation.
Treatment type — select whether you are considering standard IVF, IVF with ICSI, donor egg IVF, or frozen embryo transfer. Donor egg IVF significantly increases the estimated success rate.
Previous IVF attempts — select how many previous cycles you have had. Each previous failed cycle applies a small negative modifier to the baseline rate.
Diagnosis — select your known diagnosis if applicable. Different diagnoses apply different modifiers based on published clinical data.
Previous outcome — if you have had a previous cycle, select whether it resulted in no pregnancy, a chemical pregnancy, or a miscarriage. This provides useful signal about your reproductive potential.
The tool displays your estimated clinical pregnancy rate, live birth rate, cumulative 2-cycle success rate, and a list of personalised factors — both positive and negative — affecting your estimate.

What a Good Success Rate Looks Like
Patients often ask what success rate they should expect or demand from a clinic. Here is a realistic benchmark:
A clinically excellent IVF clinic treating a broad patient population should achieve 55–65% clinical pregnancy rates per transfer overall. Higher rates (70%+) are achievable but may reflect patient selection — clinics that only treat the most straightforward cases will naturally report higher success rates.
When evaluating a clinic’s quoted success rate ask:
- Is this a clinical pregnancy rate or live birth rate?
- Is this per transfer or per cycle started?
- Is this for all patients or only selected patients?
- Can you provide age-stratified data?
Any clinic that cannot or will not answer these questions clearly should be treated with caution. All Fertibridge verified clinics are assessed for transparent success rate reporting as part of our verification process.
Frequently Asked Questions
What is a good IVF success rate in India?
A good IVF success rate at a top accredited clinic in India is 60–72% per transfer for patients under 38. For patients over 40 with own eggs, 35–45% is realistic. Donor egg IVF achieves 65–75% across all age groups. Always ask for live birth rates per cycle started rather than headline figures.
How accurate is the Fertibridge success rate calculator?
Our calculator provides estimates based on aggregate published data from India’s top NABH and JCI accredited clinics. It is designed to give a realistic range rather than a precise prediction. Individual outcomes depend on many factors the calculator cannot capture — including specific embryo quality, endometrial receptivity, and clinic-specific protocols. Always discuss your personal situation with a specialist.
Does age affect IVF success rates in India differently than in the UK or USA?
No. The relationship between age and IVF success is biological — it reflects egg quality — and is consistent globally. A 38-year-old patient in Delhi faces the same age-related success rate factors as a 38-year-old in London. What differs is the cost of treatment, not the biological success rates.
Can I improve my IVF success rate?
Some factors are fixed — age and diagnosis cannot be changed. But protocol optimisation, choice of clinic, laboratory quality, and timing of transfer are all modifiable factors. Choosing a specialist clinic with experience in your specific diagnosis is the single most impactful choice you can make.
What success rate should I expect with donor egg IVF in India?
Donor egg IVF at India’s top clinics achieves clinical pregnancy rates of 66–76% per transfer. This is relatively consistent across age groups because success depends primarily on the donor’s egg quality rather than the recipient’s age.
Is the IVF success rate tool free?
Yes, completely free. Fertibridge never charges patients for any of our tools or services.
