IVF (In Vitro Fertilisation) has become one of the most sought-after fertility treatments in India — but the one question asked in every consultation remains the same: What is the IVF success rate? There is no single answer. Success depends on your age, ovarian reserve, embryo quality, the clinic’s laboratory standards, and whether you use your own eggs or donor eggs.
This guide breaks down IVF success rates in India by age group, number of attempts, embryo stage, and treatment type – so you can have an honest, data-informed conversation with your fertility specialist.
What Does “IVF Success Rate” Actually Mean?
IVF success rate is most accurately measured as the live birth rate per cycle — meaning how often a complete IVF cycle results in a baby being born. Some clinics report a clinical pregnancy rate, which counts a confirmed pregnancy on ultrasound and is naturally a higher number. However, not all clinical pregnancies result in live births.
Always ask your clinic: Is the success rate figure based on live births or confirmed pregnancies? The difference is significant and affects how you interpret their numbers.
IVF Success Rate by Age in India
Age is the single most predictive factor in IVF success. It directly influences egg quality, ovarian reserve (how many eggs remain), and the risk of chromosomal abnormalities in embryos. The table below reflects data from the CDC National ART Surveillance System (NASS) 2021 and ASRM 2023 Guidelines.
| Age Group | Live Birth Rate / Cycle | Clinical Pregnancy Rate | Notes |
|---|---|---|---|
| Under 35 | 40–45% | 50–55% | Best outcomes overall |
| 35–37 | 30–35% | 40–45% | Still good; slight decline in egg quality |
| 38–40 | 20–25% | 30–35% | Noticeable drop; more cycles may be needed |
| 41–42 | 12–18% | 20–25% | Donor eggs strongly recommended |
| Over 42 | 5–11% | 10–15% | Donor eggs offer significantly higher success |

IVF Success Rate for a 31-Year-Old
If you are 31, you fall within one of the most favourable windows for IVF. At this age, your ovarian reserve is generally adequate, egg quality is high, and the probability of chromosomal errors in embryos is low. The expected live birth rate is approximately 40–45% per cycle, and cumulative success improves significantly if additional cycles are needed.
IVF Success Rate on the First Attempt
Many couples ask: will IVF work the first time? The honest answer is — it might, but not always.
Among women below 35, roughly 40% of first IVF cycles result in a live birth. This means the majority of women will not conceive on the first attempt — and that is not a failure. It is biology.
The first cycle also provides your doctor with critical diagnostic information: how your ovaries respond to stimulation, how many mature eggs are retrieved, and how many quality embryos develop. This data is used to optimise subsequent cycles.
The cumulative live birth rate after 3 IVF cycles for women under 35 can reach 60–80% — a figure that underscores the importance of persistence and a long-term treatment plan.
IVF Success Rate by Number of Embryos Transferred
One of the most consequential decisions in any IVF cycle is how many embryos to transfer. Transferring more embryos increases the chance of implantation, but also significantly raises the risk of multiple pregnancies (twins or triplets), which carry higher health risks for both mother and babies.
| Embryos Transferred | Stage & Day | Live Birth Rate (Under 35) | Multiple Pregnancy Risk |
|---|---|---|---|
| 1 Blastocyst | Day 5–6 (advanced embryo stage) | 40–45% | 1–2% |
| 2 Blastocysts | Day 5–6 | 45–55% | 25–30% |
| 1 Day-3 Cleavage Embryo | Day 3 (6–8 cell stage) | 25–35% | 1–2% |
| 2 Day-3 Cleavage Embryos | Day 3 | 35–45% | 20–25% |
Single Embryo Transfer (SET) is actively encouraged for women under 35. Leading fertility centres achieve live birth rates of 56–63% with SET at the blastocyst stage, with a high singleton birth rate. To understand how blastocyst culture improves embryo selection, speak with your IVF specialist.
IUI vs IVF Success Rate
Intrauterine Insemination (IUI) is a simpler, less invasive fertility treatment that involves placing sperm directly into the uterus around the time of ovulation. While it is more affordable, it is considerably less effective than IVF.
- IUI success rate in India: 10–20% per cycle
- IVF success rate (own eggs, under 35): 45–50% per cycle
IUI is most appropriate when the cause of infertility is unexplained or involves mild male factor issues. For conditions such as blocked fallopian tubes, severe male factor infertility, or repeated IUI failures, IVF is the recommended treatment.
Donor Egg IVF Success Rate
Donor egg IVF is an effective pathway when a woman cannot use her own eggs — due to advanced age, premature ovarian insufficiency, or poor egg quality. The key distinction is that outcomes with donor eggs are determined primarily by the donor’s age and egg quality, not the recipient’s age. This is why donor egg IVF opens up possibilities even for women in their late 40s and early 50s.
Egg donors in India are typically young women aged 23–30 who undergo thorough medical and genetic screening. Their eggs are fertilised with the partner’s or donor sperm, and the resulting embryo is transferred into the recipient’s uterus. Learn more about our donor egg and sperm programme.
Emotionally, choosing donor eggs is a significant decision. We always recommend working alongside a counsellor as well as your fertility specialist when considering this route.
IVF Success Rate in India
India has emerged as one of the world’s leading destinations for fertility treatment. With over 800 ICMR-registered IVF clinics across the country, treatment is significantly more affordable than in the US, UK, or Europe — without compromising on clinical outcomes.
Top-tier fertility centres in cities like Delhi, Mumbai, and Hyderabad report success rates comparable to international benchmarks. India also has an extensive pool of egg donors, making donor egg IVF more accessible and affordable than in many Western countries.

Factors That Affect IVF Success Rate
Age alone does not determine IVF success. Multiple clinical and lifestyle factors play a significant role in outcomes:
- Ovarian reserve — the quantity and quality of remaining eggs
- Embryo quality — assessed during the laboratory phase of IVF
- Chromosomal normality — tested via PGD/PGS genetic testing (euploid embryos have a higher implantation rate)
- Uterine health — evaluated using hysteroscopy
- Sperm quality — including DNA fragmentation, assessed via DNA Fragmentation Index testing
- Lab and clinic expertise — embryology laboratory standards directly impact fertilisation and blastocyst development rates
- Lifestyle factors — smoking, alcohol consumption, obesity, and chronic stress can lower IVF success rates
- Previous pregnancy history — prior successful pregnancies generally improve prognosis
- Number of previous IVF cycles — cumulative success improves with additional attempts in most cases
- Underlying medical conditions — including PCOS, endometriosis, thyroid disorders, and uncontrolled diabetes can all affect outcomes. Read about how thyroid disorders specifically affect IVF success.
Frequently Asked Questions: IVF Success Rate
What is the average IVF success rate in India?
The average IVF success rate in India ranges from 40–45% per cycle for women under 35, declining to 5–11% for women over 42 using their own eggs. Top-tier clinics in Delhi and Mumbai report outcomes comparable to international standards. Using donor eggs can improve success rates to 50–65% regardless of the recipient’s age.
Does IVF work on the first attempt?
Approximately 40% of women under 35 achieve a live birth on their first IVF cycle. While success on the first attempt is possible, most women require more than one cycle. After three cycles, the cumulative success rate for women under 35 can reach 60–80%.
What factors most affect IVF success rate?
The most significant factors are age, ovarian reserve, embryo quality, uterine health, sperm quality, and the expertise of the IVF clinic and embryology laboratory. Underlying conditions such as PCOS, endometriosis, and thyroid disorders also influence outcomes, as do lifestyle factors like smoking and obesity.
What is the IVF success rate with donor eggs?
Donor egg IVF typically achieves success rates of 50–65% per cycle, as outcomes depend on the donor’s age (usually 23–30) rather than the recipient’s age. This makes it a viable option for women over 40 or those with poor egg quality or premature ovarian insufficiency.
Is IVF better than IUI?
IVF has a significantly higher success rate than IUI — 45–50% per cycle versus 10–20% for IUI. IUI is suitable for unexplained infertility or mild male factor infertility. IVF is recommended for blocked tubes, severe male factor infertility, repeated IUI failure, or when time is a factor due to age.
Final Thoughts on IVF Success Rate
IVF success is a journey, not a single event. While age and diagnosis are important, they are not the whole story. Choosing the right clinic, optimising your health before treatment, and following a personalised protocol can meaningfully improve your outcomes. Women in their early thirties have an excellent prognosis; women over 40 have real and achievable pathways through donor egg IVF.
Understanding how your reproductive age affects IVF success is an important first step. If you are ready to explore your options, book a consultation with our fertility team to receive a personalised assessment.
