Do male humans have mammary glands?

Yes, males have rudimentary mammary gland tissue, but it is usually non-functional and does not develop the capacity for lactation without significant hormonal stimulation.

My Flashcards

Definition

Meaning

The specialized organ in female mammals that produces milk.

A term sometimes used metonymically or in social contexts to refer to female breasts or the act of breastfeeding, though the anatomical/technical term is strictly for the glandular structure.

Linguistics

The term is anatomically precise. While often associated with 'breast', 'mammary gland' refers specifically to the glandular tissue, not the entire external structure. Its use outside technical contexts can sound clinical.

In English, 'gland' is specific; железа can be broader.

Common Mistakes

Pronouncing it as /ˈmeɪ.mə.ri/ (should be /ˈmæm.ə.ri/).
Using it as a polite synonym for 'breasts' in social conversation, which sounds jarringly clinical.
