No one is quite sure what the exact cause of Gynecomastia (also known as man boobs) is and why some men suffer and some men don't. Many factors may be attributed in the cause of Gynecomastia and it is a very common condition. Certain medications and drugs could cause the male breast to develop excess fatty tissue but research into this has been inconclusive.

But there are many, many factors which are known to contribute directly to the cause of Gynecomastia. When the male goes through the puberty phase, this is a common time for some young men to experience enlargement of the breasts, even though this is usually only a temporary state. The breast enlargement will correct itself in the latter phase of the puberty stage but sometimes will carry on for a much longer period.

More known common factors which cause Gynecomastia are aging and obesity. As the male body gets older, the male hormone production decreases which in turn can lead to enlarged male breasts. And obesity is more obvious due to the fact that excess fat has to be stored in certain areas of the body and behind the breast is one of the preferred locations and it proves to be difficult to remove.

So as you can see, Gynecomastia is not always down to just one single factor. There can be any number of causes.

Men who are known to have an XXY chromosome are usually more likely to be associated with the symptoms of Gynecomastia. Men who carry the additional X chromosome may produce more of the female hormones such as estrogen. It is this female hormone which can cause the growth of the breasts. This has been also shown when an excess of estrogen in the male body has been caused some adrenal and testicular tumors are in the body. A hyperactive thyroid can also produce excess estrogen.

Although it is very rare for the male to get breast cancer, this is another issue which can bring on Gynecomastia. And having cysts, growths and clotted blood in the chest area can also be a factor.

As you can see, there are many reasons why a man may have Gynecomastia but there are certain steps you can take to reduce the size of the breasts. An effective way of achieving this is to read the ‘Chest Coach' system. Visit my site to find out more.
