When men develop breast tissue on their chest, it can appear as if they're growing "*****". And this of course, can be quite traumatic and embarassing for men of any age, so they start looking for ways to get rid of these "*****".
Now there are two types of man **** syndromes. One is called Gynecomastia, and it's generally seen most often in young pubescent boys or elderly men. This specific medical condition is most often caused by hormone imbalances that occur when boys reach puberty, or older men advance in age.
The man ***** Gynecomastia condition is usually characterized by swelling under the nipple on one or both sides of the chest. The area tends to be about one and a half inches in diameter, is usually tender to the touch, and sometimes will even cause milk to be discharged from the boy's or man's nipple.
In rare cases, this form of man ***** can also be caused by certain types of medications and recreational drugs. Alcohol and marijuana for instance, can cause men to grow ***** in rare cases. So getting rid of the ***** for these guys is just a matter of stopping their use of alcohol or marijuana.
