Honest IVF success rates — what to expect at 28, 35, and 40
Industry-average IVF numbers are misleading. Here is what success rates actually look like by age, and what they mean for your decision.
If you've spent any time researching IVF in India, you've probably seen success rates quoted between 30% and 70%. The truth is that none of those numbers will tell you what to expect, because success depends almost entirely on two things: your age, and the cause of your infertility.
Honest, anonymised numbers from clinics I've worked with:
• Under 30 with PCOS-only infertility — 55–65% per cycle. • 30–34 with mild male factor — 45–55% per cycle. • 35–37 with unexplained infertility — 35–45% per cycle. • 38–40 — 20–30% per cycle. • 41–42 — 10–15% per cycle with own eggs. • Over 42 — under 10% with own eggs; donor egg success rates are much higher (50%+).
These are per-cycle numbers. Cumulative success across 2–3 cycles is meaningfully higher — which is why most couples plan multi-cycle budgets up front.
What the numbers don't capture: the emotional cost of each cycle, the relationship strain, the financial commitment, the side effects of stimulation. A 50% per-cycle rate sounds great until you realise the other 50% is heartbreak.
What I tell every couple at first consultation: try less-invasive options first if your case allows it. Ovulation induction + IUI works for 25–35% of couples and costs a fraction of IVF. If we move to IVF, we move with eyes open — full cost breakdown, realistic odds for YOUR situation, not industry averages.
