Men and women both have nipples because all embryos start developing with the same basic blueprint, which includes the formation of nipples before sex differentiation occurs. During early fetal development, the structures that will become nipples develop before the influence of sex hormones determines the sex of the fetus. As a result, both sexes retain nipples, even though only women typically have the biological function of breastfeeding.

Men's nipples serve no functional purpose in terms of reproduction or breastfeeding. They are a result of embryonic development and are present in both males and females before sexual differentiation occurs.
