alt Hacker News> that men have all the necessary biological wiring to be "every bit as protective and nurturing as the most committed mother
This seems like an overstatement - man can't give birth to babies (which involves transfer of the mothers biome to the baby) or feed babies (which typically involves lactation).

Is it correlation or causation?
Testosterone also drops when you dont get enough sleep, which is a universal lifestyle change for parents.

Neither of the quibbles you drew are what people usually class as protective or nurturing behavior? At least in the English-speaking world that’s later in a child’s life than birth.
I’d also note that the concern about feeding babies has been obsolete since the invention of formula.
