Freezing eggs for fertility works, but caution urged

< Previous Page

There are no estimates of how many women have had their eggs frozen. But Pfeifer’s committee cited four well-controlled European studies that compared IVF using either fresh eggs or ones that had been frozen from younger women, and found the chances of pregnancy were comparable.

What about birth defects? There are only about 1,500 known live births resulting from frozen eggs worldwide, compared with about 1 million IVF births using fresh eggs. But a recent review of nearly 1,000 of the births from frozen eggs found no increased risk of birth defects, Pfeifer said.
