What drives IVF success rates
The single biggest factor in IVF outcomes is the age of the egg, because egg quality and quantity decline over time. Other major influences include the underlying diagnosis, embryo quality, whether donor eggs are used, lifestyle factors such as smoking, and the experience of the clinic and laboratory. This estimator combines broad, published population ranges to give a general sense of what to expect — it cannot account for your individual history.
Why several cycles matter
Success is often described per cycle, but cumulative success across two or three cycles is usually higher than any single attempt. That is why clinics frequently discuss a plan over multiple cycles rather than judging IVF on one round. Treat these numbers as illustrative and use your clinic's personalised assessment to make decisions. To plan the financial side, see the IVF cost estimator, explore IVF resources, or browse recommended fertility clinics. This tool is educational and is not a personal prediction or medical advice.

- What affects IVF success most?
- Age of the egg, embryo quality, diagnosis, and clinic experience. Lifestyle factors like smoking also matter.
