Human egg mitochondria carry far fewer mutations than blood or saliva cells, defying expectations of age-related genetic decay. In a study of 22 women, eggs had up to 24 times fewer mtDNA mutations, with no rise over time. This suggests eggs may protect against harmful mutations, reassuring women delaying pregnancy and challenging assumptions about reproductive aging. Larger studies are needed to confirm and expand these findings.
