Reality keeps sliding into absurdity rendering satire mute.

Could be as simple as humans get so many neurons and need to allocate them across total set of stuff needed for life.

Women need to devote a good % of those to pregnancy mode, while men just have normal mode.

Therefore some functions may have to deal with reduced neuron allocations, because the ‘missing’ ones are required elsewhere.

Obviously a simplification of things, but with only one way of needing to be men optimize to a different configuration with a different allocation of neurons to match.
