The European Academy of Andrology (EAA) has issued a new guideline with 15 recommendations for managing these clinical cases.
The male breast, also known as gynecomastia, most frequently occurs in severely overweight men, with a manifest testosterone deficiency (hypogonadism) and partly also due to medication. This condition has a characteristic change in the shape of the male breast that reminisces the female breast shape.
Gynecomastia is a benign increase in the breast tissue of a man. The clinical incidence is not uncommon, affecting between 32% and 65% of men depending on their age. While the "male breast" in children and adolescents usually disappears by itself at the end of puberty, it is much more persistent in adult men. In about every second affected adult male there is also an underlying disorder/illness.
The aim of the breast examination in men with gynecomastia is to diagnose the underlying causes of the condition and, if necessary, to derive therapy options from them. It is also important to distinguish benign gynecomastia from malignant tumors of the breast, which can also affect men in rare cases.
The fifteen recommendations for the correct management of gynecomastia set out by the EAA are:
