Alcohol beverages as a source of estrogens

From Alcohol Health and Research World 22.3(1998) 220-227
I was looking for information on the nutritional fortification of beverage alcohol and found this article which gives clear reasons why alcohol use increases certain cancers. I was of an understandiing that cogeners the by-products of distillation and fermentation are sterols and as sterols can mimic endogenous estrogen. These compounds can cause normal processes to stop or to increase either one causing imbalances in hormomes and sexual impotency and possible suseptibility to cancer.In rats estrogens increased even in subjects with no ovaries. The clear booze like vodka have less cogeners and red wine and bourbon have the most.
As an aside, I read a headline that the FDA may ban caffeine containing alcoholic energy drinks. Isn't that their job? I mean duh. F Duh A man.
