Question 1

How accurate is this IVF success rate calculator?

Accepted Answer

This calculator provides a research-based estimate using published international fertility data including SART and CDC statistics. While individual outcomes vary based on many personal factors, it offers a meaningful starting point for understanding your likely chances. Always consult a qualified fertility specialist for a personalized assessment.

Question 2

What is a good IVF success rate?

Accepted Answer

A good per-cycle success rate depends heavily on age. For women under 35, a 40-55% live birth rate per cycle is considered excellent. For women 35-37, 33-40% is strong; for 38-40, anything above 23% is encouraging. Donor egg cycles often achieve 50-65% regardless of recipient age.

Question 3

Does success rate decrease with each failed cycle?

Accepted Answer

Slightly, yes. Each unsuccessful cycle can indicate underlying factors that lower the per-cycle probability by 2-8%. However, cumulative success across multiple cycles still increases — most patients who succeed do so within 3 cycles.

Question 4

How does PCOS affect IVF success?

Accepted Answer

PCOS patients often respond well to IVF because they typically have a high egg count. With careful protocols to avoid OHSS, PCOS patients often see slightly above-average success rates compared to age-matched peers.

Question 5

Do donor eggs improve success rates?

Accepted Answer

Yes — significantly. Donor eggs from young, screened donors can raise per-cycle success rates to 50-65% regardless of the recipient's age, because egg quality is the single biggest factor in IVF outcomes.

Question 6

What can I do to improve my IVF success rate?

Accepted Answer

Maintain a healthy BMI, stop smoking and limit alcohol, take prenatal vitamins including folic acid and CoQ10, manage stress, and choose a high-quality clinic. Treating underlying conditions like thyroid disorders or vitamin D deficiency before starting can also help.
