Some of the main differences between the sexes include physical strength, size, lifespan, fertility, and social roles. Men typically have greater muscle mass and bone density than women, which can lead to increased physical strength and endurance. Women tend to live longer than men on average. Fertility is also different for each sex; women generally have a higher rate of fertility than men. Finally, social roles differ greatly between the sexes. Women traditionally take on more childcare duties and perform domestic work in many cultures.
