Plastic and Reconstructive Surgery. Back to Men's health. Gynaecomastia sometimes referred to as "man boobs" is a common condition that causes boys' and men's breasts to swell and become larger than normal. It is most common in teenage boys and older men. Signs vary from a small amount of extra tissue around the nipples to more prominent breasts. It can affect one or both breasts. Gynaecomastia can be caused by an imbalance between the sex hormones testosterone and oestrogen.
Oestrogen causes breast tissue to grow. While all men produce some oestrogen, they usually have much higher levels of testosterone, which stops the oestrogen from causing breast tissue to grow.
If the balance of hormones in the body changes, this can cause a man's breasts to grow. Sometimes, the cause of this imbalance is unknown.
