Male infertility after 60 is probably not very impactful from a selective point of view. For 300 000 years, almost nobody reached 60 anyway.

Before. Now people are delaying childbearing. Anedacta, past year one of my work colleagues had its first child, at 62.
And delaying childbearing decreases fertility probably more than anything.
