Secondary sex characteristics are those physical features that distinguish males and females from each other, but are not directly related to reproduction. These include things like facial hair, breast development, and changes in body shape. Primary sex characteristics, on the other hand, are those physical features that are directly related to reproduction, such as the presence of ovaries or testes.
