There is a thing called sexual dimorphism. This refers to physical, physiological and even mental differences between males and females of a species, beyond their sexual organs.
The vast majority of species in the animal kingdom have sexual dimorphism, and even some plants.Males and females are fundamentally different, and in humans and all apes the males are generally bigger and stronger than the females. This isn’t just a matter of exercise. Testosterone in men promotes the growth of larger and more powerful muscles, something women cannot achieve without outside help like anabolic steroids.
Testosterone doesn’t just influence men’s muscles; it also affects their brains. Men and women are mentally different because of the different levels of testosterone and estrogen in their brains.
