Alcohol and Erectile Dysfunction: What Your Drinking Habits Are Really Doing to Your Sex Life

Alcohol, as they say, is a 'social lubricant'. In moderation — and I put emphasis on the word moderation — a drink might even decrease cases of ED, though this topic tends to be quite contested. Some compounds in wine and alcohol appear to have lightly positive effects on the cardiovascular system, relaxing the lining of blood vessels that transport blood around the body and to the penis. There are also some anti-inflammatory properties, a link between moderate alcohol consumption and 'good cholesterol', and some antithrombotic properties to boot. So all in all, some limited consumption of the nectar of the gods is not a bad thing.

Yet probably the main effect of an alcoholic drink, while wooing and cooing over your prospective bed partner, is on your sexual performance. Not because of a magical chemical compound in the drink itself, but really because one drink relaxes your mind chatter and reduces the anxiety of having to perform well enough to entice your partner into some nookie — and then again the anxiety to actually perform during said nookie. Yet this is where we enter the emotional and psychological realm while ths focus today is on how alcohol affects sexual performance in respect to ED.

So what happens when the one or two glasses become four, five, or six? You all know the drill: out and about, lurrrrrrrve and the promise of nookie are in the air, you start to relax after your first drink, words and topics flow easily, you drink some more and feel more and more involved and loving, you drink again and you are positively horny. You've gone well beyond the moderate amount, and this is where the positive effect of alcohol dissipates.

The link between alcohol and erectile dysfunction risk follows a capital J curve — the bottom of the J is where the moderate drinkers live. The right side of the J is where risk increases considerably, and this is true for both single-night binge drinking and chronic drinkers.

Alcohol is a central nervous system depressant.

This means it acts at multiple levels within the nervous system, which translates into the brain taking a spa day — relaxing in the sauna while the systems waiting for instructions from management sit idle and in disbelief. Think less startup, more stuffy government building where the pompous Minister drones on about irrelevant things while others sit grumbling on the back benches watching opportunities slip by.

The more the brain is pickled in a mounting number of drinks, the more it loses focus — and one of the areas is sexual focus. You might think about it, talk about it while marinating in alcoholic fumes, fumble heroically with the mystery that is unclasping a bra and tell yourself this is sooo sexy. It is not.

The systems waiting for the 'go to third base' instruction are confused; the message that arrives is 'whatever, mate, I'm having too good a time to help you out.' In other words, if you are tipsy, so is your dick and its entire supporting team. If you're going home in a taxi because you shouldn't drive, or whispering love poems to the wall, how do you expect Team Dick to find the keys to the door?

The occasional night out with a few drinks will not affect your sexual response in the long term. It is when we look at a habit of consuming alcohol regularly and in higher quantities that binge drinking and erectile dysfunction become part of the same conversation.

How alcohol affects testosterone — and why it matters

The cells in the body that directly produce testosterone are damaged by alcohol — less testosterone is produced as a consequence, pure and simple. This hormone has a large impact on libido, sexual motivation, and sexual response. While not the only factor, the big T is one of the powerhouses of your penis' response. And not only are the cells damaged, but prolonged alcohol consumption also disrupts the signal to actually produce the big T in the first place.

It is a well-known fact that excessive alcohol damages the liver — no surprise there. What is less well known is that an alcohol-affected liver converts testosterone into a different hormone altogether, further reducing its amount in the body.

Drinking and ED don't stop at hormones.

 Alcohol also has an impact on the cardiovascular system, with blood vessels hardening — a precursor to atherosclerosis — and it increases blood pressure, which consequently affects how blood reaches your heart, let alone how the penis hardens during arousal.

And alcohol affects sleep. Why does that matter? Because testosterone is produced during sleep — and you know the big T is happily circulating when you wake up with a hard-on. Less quality sleep, less production. You do the maths.

According to a study published in 2022 in the Indian Journal of Psychiatry, over 77% of men who already have alcohol-related ailments report various sexual difficulties — reduced libido, ED, or otherwise — and the impact of those difficulties increases with alcohol dependency. For men asking whether alcohol causes erectile dysfunction, the answer, at this level of consumption, is an unambiguous yes.

Four changes you can make to improve your overall sexual health and reduce occurrences of ED

1. Keep note of how much you drink over a few weeks. We humans are genuinely useless at tracking our own habits and will grossly over- or underestimate how much we drink. An alcohol diary will make you more aware and help you make healthier choices.

2. Try to avoid binge drinking. Don't think that staying within the weekly limits recommended by the NHS while concentrating all your drinking into the weekend is a smart move — it is not. Binge drinking is harmful, and while a one-off is reversible, multiple instances of drinking yourself silly will count towards increasing ED.

3. Give your liver a chance to regroup. You don't work 24 hours a day without sleeping, so don't expect your liver to keep its metaphorical eyelids open with cocktail sticks to cater for a constant flow of drink. Avoid alcohol completely for a few days and let your liver take a breather.

4. Prioritise sleep. Sleep deprivation or interrupted sleep — quite common after a drinking session, however limited — has a significant impact on testosterone production. Focus on a good night's sleep.
