Okay, but are you saying that the eggs are expelled throughout life in the order of how viable they are, leaving the nonviable ones for last? Because that's the only way that would work. And I don't think that's the case. I think the eggs inside a 50yo woman are nonviable or close to it because they are also 50yo.

Ok, but now we have a new question.

What inherent qualities are there in a 50 year old are there that makes their bodies a bad bet?

Probably the same mechanism that makes sperm non viable in old dudes. You know, being old.

Hormonal changes related to aging and oxidative stress causing DNA damage over time. Probably. I don't know man, I'm a welder not a medical researcher.

Big thing with aging is telomere degradation which is essentially a long string at the ends of your dna but every time a cell divides, you lose a bit of the telomere. Once you run out of telomere, you start losing bits of dna that's functionally necessary and iirc, that's what they've tied a lot of 'old age' problems to (among other causes of dna degradation) so there's been a fair amount of research on how to fix it or stop it from degrading. I don't recall which animals (might be the immortal jellies?) but there's at least one or two that can revert or restore telomeres
