What is the IVF success rate in India?
IVF success rate per cycle in India depends primarily on age: 45–55% under 35, 35–42% at 35–37, 22–30% at 38–40, 12–18% at 41–43, and 5–10% over 43 with own eggs. Cumulative success across 3 cycles reaches 60–70% for women under 35. Donor egg cycles maintain ~50–55% across all ages.
The single most important predictor of IVF success is the woman's age, because age determines egg quality. As eggs age, the rate of chromosomal abnormalities rises sharply — from about 20–30% under 35 to over 70% over 40. Most failed IVF cycles are caused by chromosomally abnormal embryos.
IVF success rate by age — the data
| Woman's age | Per cycle (own eggs) | After 3 cycles | Donor eggs |
|---|---|---|---|
| Under 30 | 50–60% | 75–85% | 50–55% |
| 30–34 | 45–55% | 70–80% | 50–55% |
| 35–37 | 35–42% | 60–70% | 50–55% |
| 38–40 | 22–30% | 45–55% | 50–55% |
| 41–43 | 12–18% | 25–40% | 50–55% |
| Over 43 | 5–10% | 12–22% | 50–55% |
Ranges represent live birth rates per cycle based on Indian and international fertility registries (HFEA, SART, ICMR). The spread reflects real variation between clinics — strong embryology labs sit toward the upper end.
What factors actually affect IVF success?
- Age — drives egg quality and chromosomal normality.
- Ovarian reserve (AMH and antral follicle count) — predicts eggs retrieved per cycle.
- Sperm quality — count, motility, morphology, DNA fragmentation.
- Embryo quality and grade — assessed by embryologists.
- Uterine receptivity — endometrial thickness, fibroids, polyps.
- Laboratory standards — often the largest non-biological variable.
Does AMH really matter for IVF success?
AMH measures ovarian reserve — how many eggs you have left — not egg quality. A higher AMH typically means more eggs retrieved per stimulation, more embryos to choose from, and a better chance of finding a chromosomally normal embryo. Very low AMH (below 0.5 ng/mL) reduces per-cycle success because the cycle may yield only 1–2 eggs.
How male factor affects IVF success
Male factor contributes to about 40–50% of all infertility cases. WHO 2021 thresholds: concentration ≥16 million/mL, motility ≥30%, morphology ≥4%. Below these, ICSI maintains fertilisation rates. Severe male factor may require surgical sperm retrieval (TESA, TESE).
Can you improve IVF success rates?
- Healthy BMI (19–25) — improves stimulation response and implantation.
- Stop smoking at least 3 months before cycle.
- Limit alcohol during the 3-month prep window.
- Optimise chronic conditions — diabetes, thyroid, PCOS.
- CoQ10 200–600 mg daily for 3 months (moderate evidence).
- Mediterranean diet — most consistent fertility benefit in research.
- Choose a clinic with strong embryology standards.
What this calculator can't tell you
An online calculator works with population averages. Several factors strongly affect your outcome but cannot be entered into a tool: embryo genetic normality (only PGT-A reveals this), endometrial receptivity, sperm DNA fragmentation, uterine structural factors, immune factors, and your clinic's lab quality.
