There is some evidence to suggest that gynecomastia may be hereditary, but
the exact genetic factors are not well understood. Having a family history of gynecomastia may increase the risk of developing the condition. Researchers have identified several genes that may play a role in the development of gynecomastia, but the relationship between these genes and the condition is complex and not fully understood. In addition to genetic factors, gynecomastia can also be caused by a variety of environmental and lifestyle factors, such as hormonal imbalances, medications, and obesity. If gynecomastia is a concern, it is important to talk to a healthcare provider to determine the underlying cause and appropriate treatment options.
