Live birth rates after IVF reach 51 percent for women under 35 using their own eggs. Rates decline sharply with age, reaching just 5 percent for women over 42. Data across diagnoses and techniques show how these factors shift outcomes beyond broad averages.
Key Takeaways
- In 2021, the live birth rate per intended retrieval for women aged <35 years using non-donor eggs was 51.3%
- PCOS patients first cycle: 48% LBR
- First cycle success under 35: 55% cumulative LBR after 3 cycles
- USA CDC 2021 Northeast: 52.3% LBR/ET <35 non-donor
- Donor egg IVF USA: 59.1% LBR/ET 2021
IVF success rates vary by age, but many couples achieve pregnancy with the right treatment.

Age-Specific Success Rates Interpretation
Mother Nature, it seems, reads the fine print on your birth certificate, politely but firmly offering a fifty-fifty chance before your mid-thirties before her probability calculator starts aggressively rounding down with each passing birthday.

Interpretation
Geographic/Regional Success Rates Interpretation
Based on these 2021 statistics, it appears that a woman under 35 in the Northeast or West U.S. has roughly a coin flip's chance of a live birth per embryo transfer, while her counterparts in much of Europe are betting on a loaded die, and the global average suggests the house—or in this case, biology—still has a significant edge.
