Issues like these reflects an evolutionary blind spot: selective pressure drops off after reproductive age, allowing defects like prostate dysfunction to persist. It's the same reason late-onset neurological diseases remain prevalent.

Shouldn't kids with grandfathers have an evolutionary advantage?

when humans were still primarily subjected to natural selection the life expectancy likely wouldn't have allowed for many grandfathers.

You only have to live to your 40s to become a grandparent in natural conditions, and your chances of living to at least your 50s have always been pretty good conditional on living long enough to reproduce at all.

Your 40s? A man could pretty easily be a grandfather at 26-28, possibly less.

Perhaps less common but 30s would probably be more likely.
