What is true concerning the mammary glands of both males and females?

Mammary glands in both males and females are composed of similar tissue structures, including lobules and ducts, which are responsible for milk production and transport in females. However, in females, these glands develop fully during puberty due to hormonal changes, allowing for lactation during and after pregnancy. In males, mammary glands typically remain underdeveloped and do not produce milk, although they can develop some breast tissue due to hormonal imbalances or certain medical conditions. Overall, both sexes have mammary gland tissue, but its function and development differ significantly.
