Alcohol Consumption & Testosterone


"Research with animals has consistently demonstrated an association between both acute (i.e., one time, one occasion) and chronic (i.e., long-term) alcohol consumption and low testosterone."

Although the link didnt work for me, I'm glad to say that I didnt have to reply with something to the effect of "this thread space could have been used for something like 'use of search function and T levels.'"


Well known fact, but that doesn't keep beer from tasting so damn good.


Mmmmm Beer. I can smell Friday night already!


Friday? What the hell?

The clock always reads Beer-thirty at LSU.

We win.


That would suck, as you would always be half an hour late for beer o'clock which everybody knows is when you can start drinking.


what? no, it can't be ... not another thread on alcohol!

geezus you are all alcoholics and know the shit is bad for you.

live. just a little.


TEST levels don't necessary, or rather I should say always decrease in healthy men. In fact, it appears that an acute, moderate dose of alcohol actually may increase TEST levels. High-dose alcohol, or when consumed by middle-aged men does, however, appear to cause a reduction in TEST.

Below is one abstract from a study that was published in 2004.

Testosterone increases in men after a low dose of alcohol.Sarkola T, Eriksson CJ.

BACKGROUND: Heavy acute alcohol drinking decreases blood testosterone in men due to an effect on the testicular level. An acute increase in blood testosterone levels after a low alcohol dose has, however, recently been reported in women. The objective of this investigation was to study the effect of a low alcohol dose on testosterone in men and further elucidate the mechanism behind the effect by using 4-methylpyrazole, an inhibitor of alcohol metabolism. METHODS: A double-blind placebo-controlled interventional crossover trial in random order (n = 13). RESULTS: After intake of alcohol (0.5 g/kg, 10% w/v), an acute increase in plasma testosterone (from 13.5 +/- 1.2 nmol/liter to 16.0 +/- 1.6 nmol/liter, mean +/- SEM; p < 0.05), a decrease in androstenedione (from 5.1 +/- 0.4 nmol/liter to 4.0 +/- 0.3 nmol/liter; p < 0.05), and an increase in the testosterone:androstenedione ratio (from 2.8 +/- 0.3 to 4.2 +/- 0.4; p < 0.01) were observed. The effects were not observed during pretreatment with 4-methylpyrazole (10-15 mg/kg orally), which inhibited the ethanol elimination rate by 37 +/- 3%. CONCLUSIONS: Alcohol intake affects the androgen balance in men through an effect mediated by the alcohol-induced change in the redox state in the liver.

So is there a way of calculating what quantity of alcohol would result in testosterone levels decreasing? Something like g/kg of bodyweight.


My father has been drinking Budweiser for 40 years and he is more of a man than I could ever be. That lumberjack SOB is full of Test.
