Researchers Identify Age of Fertility Wall for Women
Newser • • health
Key Points:
- New research from Italy indicates that women in their late 40s experience a decline in IVF success rates even when using young donor eggs, with notable drops starting at age 49.
- Women aged 35–40 had a 54% pregnancy rate and 46% live birth rate, while those 49 and older saw these rates fall to 43% and 32%, respectively, with miscarriage risk doubling from 24% to 38%.
- The study suggests the reduced success is linked more to age-related changes in the womb lining rather than egg quality, offering potential for future treatments targeting the uterine environment.
- Lead researcher Dr. Beatrice Crestani emphasizes that donor eggs do not completely "reset" fertility but that meaningful success rates still exist for older women undergoing IVF.
- Experts recommend using these findings to better counsel older IVF patients, ensuring informed decisions without discouraging treatment.
