By how much does alcohol increase estrogen in men and how long does it take for levels to return to normal after consumption?

Alcohol is a poison that never did anybody any good, ever, so stay away from it. It will destroy your brain cells, damage testicular cells that make testosterone, facilitate development of cancer in many organs, cause hepatitis, cirrhosis and pancreatitis etc. There is no safe level of alcohol intake. Quit while you are ahead.

Usual amounts 0f alcohol imbibed by men does not usually effect hormone levels. There must be a good reason why you ask....
