Does drinking affect testosterone levels in men?

Yes, acutely and chronically. Alcohol inhibits the hypothalamic-pituitary-gonadal axis at multiple levels. Acutely, ethanol and acetaldehyde directly suppress Leydig cell testosterone production in the testes. In men who drink above 14 units per week chronically, the cumulative effect produces measurably lower free testosterone, elevated sex hormone-binding globulin (SHBG), and in some men, elevated estradiol from alcohol-induced aromatase stimulation. The effect is dose-dependent and reversible with cessation.

Men who report weight loss and testosterone normalization after stopping drinking are not describing a placebo effect, the forum accounts are biologically accurate. The improvement comes through two simultaneous pathways: direct removal of HPG axis suppression, and visceral fat reduction (visceral fat carries high aromatase activity, converting testosterone to estrogen). The men who discover that alcohol was a significant contributor to their fatigue, libido changes, and body composition difficulties often become the most committed non-drinkers in any room, because the data from their own bodies is more convincing than any study.

What to do: If you have low testosterone symptoms and are drinking above 14 units per week, reduce alcohol for 90 days and recheck total testosterone, free testosterone, and SHBG before pursuing TRT evaluation.
