How does DNA Affect Egg Quality
As you age, the DNA inside your eggs begins to degrade
Because our eggs have been with us since before we were born, they’re exposed to all sorts of damaging, but mostly unavoidable, influences throughout our lives: fevers, infections, stress, toxins, free radicals. And because human cells, including eggs, are fragile, this exposure can lead to little “mistakes” in our egg cells’ DNA, called chromosomal abnormalities.
Once a cell’s DNA is degraded, it can’t be fixed medically or “healed.” In other words, once an egg becomes abnormal, it can’t become normal again—egg quality cannot be improved. Egg quality is fairly black-and-white—either an egg is genetically “normal” (euploid) or it’s not (aneuploid), and as women age, a higher and higher percentage of their eggs are abnormal.
Since DNA is like an instruction manual for our cells, any damage to your DNA can prevent that cell from doing what it’s supposed to do—which, in the case of the egg, is make a healthy baby.
