As I have said, that's irrelevant. One could equally say that if men had shorter legs or were smaller or something, they wouldn't have to manspread or take up as much room on the subway!
That's self-evidently true though. If men were shorter--more like women--public transport would be more comfortable for them.
But you did not suggest giving more space to meet the needs, biological or whatever, of women, would be a solution (in fact you wrongly said that they already had as much or more space) which is in contrast to you saying that more space would ease the manspreading problem.
It's self evident that including more stalls for women will reduce queue length for women. What would be a dispute about that? Not mentioning it isn't "in contrast" to anything else because you can't contrast unuttered words.
In any case, in terms of public transport, it isn't just "more" space for men, it's about differently-designed space. It would be about seats that are higher off the ground than they are at the moment (which doesn't take up more "space") and seats with different seat pitches.
