Yes, testosterone and other parts of male physiology are what lead to men having more muscle mass on average. Men and women have different average sizes, so we don’t need to debate whether men are larger or women are smaller, both are true. The main takeaway from the muscle mass point for me is just that there’s very little difference in strength between men and women per kilo, when normalizing against lean body mass. It’s just a good thing to keep in mind when taking about these sex differences, since there’s a lot of misleading framing and wrong impressions, right?
