I should have said we have perfect DNA eggs during our pregnancy lifespan. I'm not sure how to phrase it. The age range of when average women have pregnancies. 20-35.

Also the aneuploid egg thing is a very specific type of degrading. It more often results in miscarriages. Though sometimes children are born with a missing chromosome from this type of errors.

Oh, so it doesn't really disprove the manosphere woman expiration date.. it's more like both sexes are done around 30.

Well neither sex is "expired" at 30. Because people have much higher value than their breeding potential.

But in terms of passing on the best of yourself to your offspring, . Yeah there is a loss of quality over time.

That quality loss might be higher in males (,because of sperm properties) but ultimately yes, it would be better to save eggs and sperm from an age before 30.

I wouldn't choose a partner based on how old they are though. There are much more important factors like if they would be a good parent.
