On average, males are heavier than females due to several biological factors. These include:
- Larger skeletal size and bone mass: Men typically have larger bones and more bone mass than women. This difference in bone density contributes significantly to their overall weight.
- Higher muscle mass: Men tend to have a greater proportion of muscle mass compared to women, which contributes to their heavier weight.
- Hormonal differences: Testosterone, a male sex hormone, promotes muscle growth and development, while estrogen, the primary female sex hormone, generally leads to lower muscle mass and higher fat storage.
These factors combined result in males being, on average, heavier than females, even when they have the same height.
