Gynaecomastia at puberty usually clears up as boys get older and their hormone levels become more stable. As men get older, they produce less testosterone. Older men also tend to have more body fat, and this can cause more oestrogen to be produced. These changes in hormone levels can lead to excess breast tissue growth.
