That’s not supported. Those errors are not significant until the woman is nearing 40 and after.
At which point, most women are not having pregnancies.
Also there is a specific error associated with eggs. It has to do with chromosome numbers. Is specific to disorders like downs syndrome and miscarriage. Called “aneuploidy”.
Whereas sperm dna declines faster with age and is more prone to damage/changes from environmental factors like diet, exposure to chemicals, and the like.
I suppose if someone was planning or at least considering the possibility of having biological children after age 35 (mother and/or father) then it would be realistic to save back sperm and egg from an earlier age to reduce multiple types of risk.
