Alcohol and erectile dysfunction: the sober truth

Alcohol and erections don’t mix.

"Whisky dick." "Brewer's droop." Even "the sambuca sag" (we made that one up, though we wouldn't be surprised if it's out there). The nicknames are funny. What's actually happening to your erections isn't always.

A big night out can leave you unable to perform. If the drinking becomes a habit, it can do more lasting damage. Here's what alcohol actually does to your erections, and when it's worth taking seriously.

Does alcohol cause erectile dysfunction?

Yes. The NHS lists alcohol as one of the more common causes of erectile dysfunction (ED).¹ A drink or two won't do much to your performance, but drink heavily, regularly, or both, and it starts to affect the blood flow, nerves and sensitivity your erections depend on.²

The damage falls into two categories: what a heavy night does to you the next morning, and what years of heavy drinking can do for good.

Short-term effects: what a heavy night does to your erections

Drink a lot in one sitting and your blood pressure raises, which can affect other systems that influence erectile function.³ This is part of why a heavy night can leave you underperforming.⁴

Alcohol is dehydrating too, and dehydration lowers blood pressure further while reducing the fluid your body has to circulate.⁵ Less blood flow to the penis makes it harder to get, and stay, hard.

On top of that, alcohol dulls your nervous system. It slows your reactions and blunts sensitivity, including in the penis, so arousal and orgasm both become harder to reach.²

Long-term effects: can drinking cause permanent erectile dysfunction?

The UK's Chief Medical Officers recommend drinking no more than 14 units a week, roughly six pints of average-strength beer.⁶ Stay under that and, the odd bad night aside, alcohol is unlikely to cause lasting problems. Go well over it for a long time, and the risk changes.

Long-term heavy drinking can damage the nerves that carry the signal from your brain to your penis, a condition called alcoholic neuropathy.⁷ It happens partly because alcohol stops your body absorbing and storing vitamin B properly, and vitamin B is essential for healthy nerve function.⁷

The more you drink, and the longer you drink for, the higher your risk of erectile dysfunction becomes.⁸ In some men, nerve damage like this can become permanent, so a persistent pattern, not just one bad night, is worth treating as a reason to cut back.⁷

What actually helps:

• Cut back. Staying within 14 units a week is the single biggest thing you can do for your erections.

• Move more. Cardiovascular exercise improves circulation, which helps you get stronger erections.

• Find your inner zen. Meditation and yoga both help you relax, and relaxation is linked to longer-lasting erections.

• Get help if you need it. If drinking feels out of your control, your GP or a sexual health clinic can point you towards support, and there are charities who specialise in it too.

Is it safe to take ED medication with alcohol?

Taking sildenafil or tadalafil isn't unsafe just because you've had a drink.⁹ The problem is mixing a large amount of alcohol with either drug: both lower blood pressure, and combining them can cause dizziness, a racing heart, headaches or fainting.⁹

One or two drinks alongside your medication should be fine. A heavy session isn't the time to take it.

Drinking isn't the only thing that can get in the way of your erections. If you want the full picture, here's what else commonly causes erectile dysfunction, and what recreational drugs can do to your sex life.

The numan take

Drinking too much, whether it's one big night or a regular habit, can get in the way of your erections. Short-term, it's usually nothing to worry about. Long-term, it's worth taking seriously, because some of the damage doesn't reverse itself.

Cut back, move more, and if you're struggling to get or keep an erection more often than not, it's worth looking into treatment.
