Does Alchohol convert testosterone into estrogen

Yes. Alcohol—particularly its toxic metabolites—can increase aromatase activity, promoting the conversion of testosterone into estrogen in multiple tissues, including the liver. 1

• Toxic metabolites and aromatization: Alcohol’s toxic metabolites can increase testosterone-to-estrogen conversion; aromatase is the enzyme involved, and the process can occur in many tissues. 2
• Possible effects of sustained intake: Regular alcohol consumption can increase estrogen levels. In males, an altered testosterone-to-estrogen balance may contribute to breast-tissue growth (gynecomastia), reduced sex drive, and increased fat storage. 3
• Amount matters: The hormonal effects vary with dose and pattern of exposure; small acute amounts have shown different testosterone effects than repeated or chronic intake. 4
