Alcohol and Testosterone: The Acute and Long-Term Effects of Alcohol on Hormones

Alcohol is a widely used depressant that we humans most often drink in the form of ethanol. And ethanol – like everyone who has hugged a toilet seat at 4am knows – is toxic for the human body. But just how toxic? How do testosterone and alcohol interact in our bodies? And what kind of effects does it have on the endocrine system?

The magic of alcohol is fairly simple: because it’s a depressant, it slows down various bodily functions, which in turn triggers the feelings of drunkenness.

Alcohol also slows down inhibitions, which is why you might get the feeling of needing to poke everything and everyone around you after 10 shots of tequila…

…Sadly, this mission of having sex with everything that moves can often become impossible, since 10 shots of tequila is enough to dramatically slow down your sexual functions (ie: the battle sword might not rise to the occasion anymore).

This negative effect on the sexual function is mainly caused by a dramatic drop in the male sex hormone: testosterone…

…And here’s why it takes place:

Alcohol and Testosterone Production

Alcohol and Testosterone productionLet’s just start by the fact that you do not have to completely give up drinking in order to have naturally high testosterone levels…

…Since few drinks here and there ain’t enough to cause any dramatic reductions in testosterone. When it comes to alcohol and testosterone, it’s the dose that counts.

However, if you’re an alcoholic, and drinking yourself to the point of passing out on several days of the week, then you can be damn sure that your testosterone production has tanked (and you probably know this yourself already because of the negative effects it has on sexual functioning).

Here are the already known mechanisms of action in how alcohol lowers testosterone:

And here’s some research:

a) It has been noted in several rodent studies that consumption of alcohol lowers testosterone levels significantly (study, study, study, study). One study in particular is rather alarming, since it showed a 50% reduction in testicle size in rats who were fed a diet with 5% of calories coming from ethanol.

b) Multiple human studies have found that heavy consumption of alcohol reduces testosterone levels (study, study, study, study). It’s also seen that men who suffer from alcoholism have significantly lower testosterone levels, and higher estrogen levels, than men without alcohol problems, even if they have a perfectly functioning livers (study, study, study, study).

c) But how much is too much then? It might come as a relief to some that a low-dose (0.5 g/kg) of alcohol has actually been shown to slightly increase testosterone levels. And a moderate-dose (equivalent to 1,5 glasses of red wine) only lowered testosterone levels by 7%. Even more surprising is that in this study, 1g/kg of alcohol (that’s about half a glass of vodka for most men) taken post-workout, was able to increase testosterone levels by ~100%! Take that study with a grain of salt though, since another one found out that if you work out drunk or in hangover, the testosterone lowering effects of alcohol will significantly increase in duration.

Conclusion on Alcohol and Testosterone

As you can see, increasing testosterone naturally and alcohol consumption don’t go hand in hand, as it negatively impacts a wide variety of systems needed in normal endocrine functions.

However, lower dosages are probably fine, and can even increase testosterone levels slightly (I have no idea why). Moderate dosages are not that bad either (see that 7% reduction above).

It’s probably safe to say that 1-3 drinks are not enough to mess up your testosterone production, but anymore than that and the negative effects will start showing up.


If you are looking for a natural supplement to boost your testosterone, I would recommend TESTRO-X.

    As an alcoholic I spent many years drinking too much every night, and for about the last three months have drank moderately, maybe once per week or so. This isn’t my full story of course but my main questions are how long does it take for the endocrine system to balance out (ie make enough testosterone again) and is it possible the damage is permanent? I have zero sex drive, useless dick, etc.

    • vlade on 18/04/2015 at 02:12

      I don’t think it’s permanent. I would say you should see your test go back to normal pretty soon if it has been three months.

      Message me if you need help.

      • SmashOnSight on 13/09/2015 at 09:12

        Can i message you? I have quit drinking completely and work out alot. ZERO SEX DRIVE THO.

      You need a full blood test panel. Your liver may still be recovering, you may have diabetes or pre-diabetes, hypothyroidism, etc. In the meantime, I would suggest exercise, especially weight training. Start out with light weights, but be consistent. If you are overweight, try the Atkins or paleo diet, as excess fat is a primary libido killer. Only do this diet until your lab results come in because if your kidneys are not functioning properly, too much protein would worsen kidney function. Please see a doctor ASAP and get that blood test panel!

        Good point about the kidneys and protein. Yes, see a doctor.

    Alcohol raises dopamine levels which correlates with testosterone

    • Oliver Wingenter on 10/04/2017 at 21:04

      The brains of deceased alcoholics to have fewer D1 dopamine receptors. This leads to a state of hypodopaminergic. Dopamine deficiencies are also often associated with conditions such as depression and psychological disorders.

  3. […] 5. Drinking too much alcohol – to specify this is for the binge drinkers on the weekend or those who indulge during the week as well. To be short, chronic alcohol consumption has a drastic impact on your ability to produce testosterone, in turn, it also causes the body to produce more estrogen. (5)  NOOOOO!!!!!  Having a drink here and there, will have a small effect on testosterone levels, but not enough to cause any real issues.  Here is a great article with more detail on alcohol and it’s effects on testosterone, with a lot back links to studies supporting it… [click here] […]

    Here’s my issues. I have spent so, so much time reading about phytoestrogens, 5-alpha reductase, T, DHT. It goes on and on and I’ve tried a number of different techniques. I was convinced beer was bad and red wine was good for a while. But red wine is a DHT inhibitor and hops in beer increases prolactin. Prolactin is essential for transporting DHT. Antipsychotics increase prolactin. One of the other effects of antipsychotics is they INCREASE facial hair growth. Other studies have said yeast in beer increases the size of prostate: a symptom associated with HIGH DHT. I’ve come to the conclusion reading literally hundreds of medical studies cover to cover that this stuff is REALLY complicated.

    My fiance and I have been together for a few years now… I have had two miscarriages, one was a blighted ovum which is where u have everything but a baby in your uterus.. anyway he drinks to get drunk on a regular basis and it seems like he has most his sex drive.. porn turns him on, to pleasure himself but we never have intimate relations or really any relations anymore… is this due to drinking beer and his hormones. … please help. .. it relationship is going down hill fast !!!!

    • worried on 06/07/2016 at 17:31

      Not most his sex drive!!!! Lost most of his sex drive

    • VanceEdwards on 09/03/2017 at 08:50

      Stop the madness now and get out unless he does a complete 180, which is highly unlikely. Sit him down about the drinking and just ask him “What are you running from that’s inside you?” Anyone who continually has to change their emotional state (using alcohol, drugs, porn…) is running from themselves. The amount of personal development it takes for him to tackle those fears and issues head on and keep working on them is massive, just know there’s a good chance he’s not going to change.

    PD Mangan writes that red wine contains “powerful inhibitors of aromatase.” I have heard and observed much anecdotal evidence that the net effect of moderate red wine dosing is a rise in T (at least short-term).

    Found this site last week; wow, great work, Ali! Love that micronutrient PDF. As I record into Diet Organizer everything I eat, I was stunned to see that most days my zinc consumption was half of the RDA! So, I ordered zinc supps and boron, too. My diet can best be described as 90%+ “real foods,” plenty of eggs, good oils, “clean” carbs.

    Anyway, alcohol. I have been a heavy drinker for decades, meaning 400-500 ml’s of spirits most evenings. I don’t have hangovers, I’m fresh and good to go in the AM. My liver functions are in the “Excellent” category, probably attributal to some combination of genes and my high consumption of saturated fats, and little poly unsaturated. Lots of research shows that SFA’s can not only prevent FLD, but heal it.

    I’m just shy of age 71. I’ve always had a high sex drive, still do. I’ve only had two T tests, three years ago, 260, recently, 290. I don’t know if that was normal variation, or due to progesterone cream applications over the last few years. My Medicare insurer turned down a prescription the urologist wanted for Androgel. To help with weight loss. Despite those T numbers, I’m still randy as hell, and despite my alcohol consumption, my balls are still huge per internet sources. And many lovers over the years. (The urologist didn’t say anything was wrong.) The other morning I woke up with wood, walked out to the patio, and urinated a strong stream with a dick curving heavenward.

    Anyone care to explain this impossibility?
