IVF Success Rates — Own Eggs

Live birth rates per transfer using own eggs (fresh cycle). Source: SART (Society for Assisted Reproductive Technology).

Under 35
~60%
35–37
~50%
38–40
~35%
41–42
~20%
43+
~10%

* Success rates vary by individual circumstances. The above are reference figures. Consult your physician for a personalized assessment.

Donor Egg IVF Success Rates

Using eggs from younger donors significantly improves outcomes — especially beneficial for patients with diminished ovarian reserve or advanced age.

Donor under 35
~65%
Recipient (any age)
~55%

Donor egg IVF success rates are primarily determined by the donor's age, not the recipient's. This means women over 45 can still achieve strong success rates using donor eggs.

Cumulative Success Rates (Multiple Cycles)

One unsuccessful IVF cycle does not mean there is no hope. Cumulative success rates over multiple cycles are significantly higher than a single cycle:

1st transfer
~45%
Cumulative 2 cycles
~65%
Cumulative 3 cycles
~80%

* Cumulative rates apply to patients under 38 using own eggs. Actual outcomes vary by individual circumstances.

Frequently Asked Questions

What does the success rate number mean? Is it pregnancy or live birth?

All rates shown on this page are Live Birth Rates — the percentage of embryo transfers resulting in a live-born baby, not just a positive pregnancy test. Live birth rate is the most rigorous and meaningful measure of IVF effectiveness.

Will my personal success rate match these numbers?

These figures are reference benchmarks. Your actual success rate will vary based on many personal factors: ovarian reserve (AMH, AFC), cause of infertility, uterine condition, embryo quality, and whether PGT genetic testing is used. At your first consultation, your physician will provide a personalized assessment based on your specific situation.

What factors most affect IVF success rates?

The biggest factors include: (1) Female age — the single most important factor, directly determining egg quality; (2) Ovarian reserve — AMH level and antral follicle count reflect the quantity of available eggs; (3) Embryo quality — number of eggs retrieved, fertilization rate, and blastocyst development rate; (4) Uterine factors — endometrial thickness, morphology, and receptivity; (5) Cause of infertility — male factor or recurrent loss may require specific evaluation.

What should I do if my first IVF cycle fails?

Do not give up. Your physician will analyze the cycle results in detail — eggs retrieved, fertilization rate, embryo quality, implantation outcome — to identify possible reasons for failure. The next protocol, medications, or transfer strategy can then be adjusted. Many patients succeed on the second or third cycle. If multiple cycles fail, donor eggs, PGT screening, or other approaches may be considered.
