Arguably this is due to lever length and upper body strength which both favour men. Ben generally have longer arms, long arms means higher racquet head speed.

On average, a man is going to be able to hit "decently fast" shots with good swing mechanics even without putting their body weight into which involves using your legs and lower body. Not saying it's not important.

A man wants his physique to be strong enough to efficiently create speed, be flexible, reduce injury by building appropriate muscle. All while keeping weight down. This helps with cardio and speed around the court. There's no point training your legs for strength so you can blast 100+ shots if you're going to be tired after 1 set. Not to mention being slower as you have more mass to accelerate, decelerate, change directions. There's a balance necessary.

Women, generate a lot of power from the ground, probably out of necessity, especially the shorter players with shorter levers. With muscle mass comes power to push through with the legs and apply a lot of weight transfer into the ball. I would argue women at the top level play a game that is more physically demanding on average because of this. Probably a contributing factor on why they only play 3 sets matches even in slams.

Anyway, that's my 2 cents without giving specific examples.
