Hello, based on your description, you should have gynecomastia. Normally, male breasts do not develop. When individual pathogenic factors lead to a relative or absolute increase in estrogen levels in the body, and breast epithelial cells are stimulated by excessive estrogen, a very small number of men may develop unilateral or bilateral breast enlargement. Male gynecomastia is called gynecomastia, and it is more common in the period before and after puberty and in old age. Pathologically, it is characterized by the proliferation of ducts without alveolar proliferation. It is generally divided into two major categories: primary and secondary. Primary gynecomastia is more common in pubertal boys and elderly men, mainly caused by transient increases in endogenous estrogen or decreases in androgens, and it often resolves on its own. Secondary gynecomastia is commonly seen in liver diseases, testicular diseases, adrenal diseases, thyroid diseases, diabetes, and tumors of the urinary and nervous systems. Long-term use of estrogen in prostatic diseases, or long-term use of certain medications in other diseases, such as reserpine, rifampin, or digitalis, can also cause breast development. It generally resolves after discontinuing the medication. Additionally, intersex and congenital testicular hypoplasia can also lead to breast enlargement. You likely have primary gynecomastia and do not need treatment; it will disappear after puberty.
