Do you have a source for that?
Not merely that men have more muscles, but that somehow male muscle is stronger than female muscle?
First three that came up, there are loads more strudies
1 - "Male skeletal muscles are generally faster and have higher maximum power output than female muscles. Conversely, during repeated contractions, female muscles are generally more fatigue resistant and recover faster. "
"there are major differences between female and male skeletal muscles, including differences in energy metabolism, fiber type composition, and contractile speed. Generally, male muscles have a higher capacity for anaerobic metabolism and generate a higher maximum power output than female muscles"
2 - this one is a bit general, but.
"Previous studies have identified over 3,000 genes that are differentially expressed in male and female skeletal muscle."
3 - Here is the real summery for you
"Women athletes are known to be less strong and powerful than equally trained men, muscle strength of women indeed, is typically reported in the range of 40 to 75% of that of men"
Other studies confirmed that gender differences in strength may be accounted to LBM but reported that the differences in power performances were still apparent regardless of body composition, and muscle mass. These results support the idea that differences between genders in anaerobic power and jumping capacity could not be accounted for by differences in lean body mass only.
Despite no significant differences between genders in muscle fibers number were reported, a qualitative difference in muscle tissue, such as a higher concentration of glycolytic enzymes and greater proportion of fast type muscle fibers, may explain the disparity in strength. Glycolytic capacity, as well as the muscle area occupied by fast type fibers, indeed, have been reported to be greater in male than in female individuals"
When adjusted for body mass, all performance variables were significantly different between male and female groups. After adjusting for the muscle thickness of PEC, ANCOVA revealed a significant difference between genders for bench press 1RM and for bench press throw power"
This last one is interesting. Its TL:DR, is essentially, men and women are just built differently. Down to the type way the muscles grow. A women's typical body has more fat and less muscle than a man at the same level of exercise and training. If a women wants to beat me at sprinting, she will have to train for years to catch up to a typical guy who spends his days playing games on the couch.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7930971/What bugs me is that this science has been known for ages. Men and women being built differently is not a new discovery. We have known this forever.
Yet we are now at a point where some people believe a women and a man are only different because they identify differently, and you can change this by simply identifying in another way.
This is literally a statement against fact, and fairly obvious logic.
