Primary sex characteristics include the reproductive organs, such as the testes in males and ovaries in females, which are directly involved in reproduction. Secondary sex characteristics, on the other hand, are physical and behavioral features that develop during puberty but are not directly involved in reproduction, such as breast development in females and facial hair growth in males.
