There are various reasons for male mammary gland dysplasia, such as physiological, pharmacogenetic, pathologic, etc. Physiological and pharmacogenetic can generally recover by themselves, but pathologic can not necessarily recover by themselves. 1. Physiological: men will have physiological development in the process of growing up, and there are individual differences in mammary gland dysplasia, some develop early, some develop late, which is generally a normal phenomenon, and can be recovered on its own without special treatment. 2. Pharmacogenetic: if the patient has a history of taking drugs, such as estrogen, etc., the drug itself has the effect of stimulating the development of breasts, and there may be some adverse reactions to the drug, you should go to the hospital in time to consult, and stop using the relevant drugs. 3. Pathological: If you exclude the above two cases, you should consider whether there is endocrine disruption of excessive secretion of estrogen or the mammary glands themselves appear lesions, there is a lump, this situation will not recover on its own, and need to be treated. It is recommended to consult a doctor in time to clarify the specific cause of breast development disorder and treat according to the cause.
