The truth is, in regards to fertility, we have perfect eggs our entire life.
That is demonstrably false. While it’s true that oocytes have remarkable properties to maintain their proteins over long periods. And more-recent research suggests egg quality isn’t nearly the infertility culprit it was once thought to be (as compared to, ovarian health, for instance). The fact remains that as women age, chromosomal abnormalities DO occur at higher rates.
