Fertility Clock Ticks On: Age Impacts Donor Egg Success
7 Jul
Summary
- Fertility treatment success drops significantly for women over 49.
- Age-related changes in womb lining may affect implantation success.
- Donor eggs improve chances but don't entirely reset the reproductive clock.
New research suggests that fertility treatments using donor eggs have a significantly lower success rate for women aged 49 and older. Experts studying 1,774 women found that age-related changes in the womb lining may be responsible for reduced pregnancy and live birth rates, along with a higher risk of miscarriage.
These findings challenge the notion that donor eggs completely reset the reproductive clock. While success rates remain meaningful even at advanced ages, the study indicates that reproductive aging's effects, particularly beyond 49, are not entirely eliminated by using younger donor eggs. Researchers believe future treatments might address these womb-related age changes.
