I don't get why people immediately scream "p-hacking" and "cherry-picking data" when the simpler explanation is that for women over the age of 35 their own fertility issues dominate to the point where the effect of male age is lost in the noise. If women have less difficulty conceiving, it stands to reason that other factors are easier to discern. Which in no way would invalidate the existence of those other factors. On top of that, why would this be surprising to anyone? Sperm quality decreases with age, and there is such a thing as andropause. https://pubmed.ncbi.nlm.nih.gov/11850741/ https://pubmed.ncbi.nlm.nih.gov/11850741/
