Gynecomastia is the medical term for ‘man boobs’ – when breast-like bulges appear on a man’s chest. Gynecomastia is very common – it is believed to affect around 70% of men, usually during puberty when the body is being flooded with hormones. For some, the breast-like lumps naturally reduce over time; for others, they remain into adulthood.
An imbalance of the sex hormones testosterone and oestrogen is the primary cause of male breasts, which can happen naturally, or as the result of taking hormone medication (e.g. steroids).

For some men, these negative emotions can contribute to more serious issues later down the line, including depression and related mental health conditions.
