Can Alcoholism Cause Male Breast Enlargement?

My son is an alcoholic.  He has bunches in both breasts, could this have anything to do with the liver?  He is having blood work done.

Chronic alcohol intake in high doses can damage the testicles and cause them to shrink (atrophy). Normally, the testicles produce the male hormone testosterone. When the testicles are damaged, the testosterone blood levels decrease. Low blood testosterone levels in males can lead to the development of female physical characteristics, such as weight gain and breast tissue enlargement.
