Erectile dysfunction (ED) is a common condition affecting men of all ages, though it becomes more frequent with age. It involves difficulty achieving or maintaining an erection firm enough for sexual activity. For some men, it happens occasionally and resolves on its own, but for others it can become a persistent issue that affects confidence, relationships, and overall wellbeing.
Alcohol is a recognised contributor to erectile difficulties. While moderate drinking may not cause long-term harm, excessive or frequent alcohol use can interfere with sexual function in several ways. Understanding how alcohol affects erections can help men make informed decisions about their health and seek appropriate support when needed.
This article explores the impact of alcohol on erectile function, the difference between short-term and long-term effects, and how services like Dr Fox can assist men experiencing ongoing symptoms.

How Alcohol Affects Sexual Function
Alcohol acts as a depressant on the central nervous system. Even though small amounts can create a temporary sense of relaxation or confidence, alcohol reduces how well the nerves work and slows reaction times throughout the body. This can interfere with sexual arousal and physical responses.Alcohol also affects blood vessels. Erections depend on increased blood flow to the penis. Alcohol can cause blood vessels to dilate excessively or reduce the body’s ability to maintain adequate pressure, making it harder to achieve or sustain an erection.
Hormonal balance can be influenced too. Long-term alcohol use may reduce testosterone levels, which can affect libido and erectile function.
Short-Term Effects of Drinking on Erections
Many men notice erection difficulties after drinking more than a small amount. The short-term effects of alcohol can include:
- Reduced penile sensitivity
- Delayed or weakened nerve signals
- Slower blood circulation
- Decreased ability to stay focused on sexual activity
These effects may result in difficulty getting or maintaining an erection during or after moderate to heavy drinking, even in men who do not usually experience ED. In many cases, erectile function returns to normal once alcohol has left the system. However, frequent episodes can cause anxiety or concern, which may further impact future sexual performance.
Long-Term Alcohol Use and Erectile Dysfunction
Regular, heavy, or prolonged alcohol consumption increases the likelihood of persistent erectile dysfunction. Long-term effects include:
Cardiovascular impact
Continuous alcohol use can contribute to high blood pressure, damage to blood vessels, and reduced overall circulation. Since erections depend on healthy blood flow, these changes increase the risk of ED.
Hormonal disruption
Alcohol can reduce testosterone production. Lower testosterone may affect libido, energy levels, and erectile function.
Liver disease and metabolic changes
Liver dysfunction linked to alcohol misuse can alter hormone processing and circulation. It can also be associated with other risk factors such as weight gain, diabetes, and high cholesterol, all of which are linked to ED.
Depression and medication use
Excess alcohol is associated with depressive symptoms and anxiety. Some men may also require medication for mental health or physical conditions, and certain treatments can further influence erectile function.
Fertility and Reproductive Health
Alcohol can affect sperm quality, sperm count, and hormone levels involved in fertility. While ED and fertility are separate issues, the factors influencing one can affect the other. Long-term heavy drinking may influence both sexual performance and reproductive potential.
UK Low-Risk Drinking Guidelines
UK guidance recommends that men and women drink no more than 14 units of alcohol per week. This should ideally be spread over three or more days.
Examples of unit measurements include:
- One pint of average-strength beer: around 2 units
- A 175ml glass of wine: around 2 units
- A 25ml measure of spirits: 1 unit
Having several alcohol-free days per week and avoiding binge drinking can help reduce health risks, including those associated with erectile problems.
When Alcohol-Related ED Becomes a Pattern
Occasional erection problems after drinking do not necessarily indicate ongoing ED. However, persistent difficulties, even when sober, should be taken seriously.
Warning signs include:
- Erection problems happening regularly
- Ongoing issues for more than three months
- Reduced sexual desire or performance-related anxiety
When to Seek Medical Advice
The NHS advises seeking help for recurring erectile dysfunction, especially if lifestyle changes do not resolve the issue. A GP or regulated online service can assess symptoms, explore lifestyle factors such as alcohol use, and check for underlying medical conditions.
Treatment Options
Treatment depends on the cause. Reducing or stopping alcohol intake often improves symptoms, particularly alongside lifestyle adjustments such as weight management or quitting smoking. Medications such as sildenafil or tadalafil may be prescribed following clinical assessment.
Dr Fox ensures all prescribing doctors are GMC-registered, medications are MHRA-approved, and dispensing pharmacies are GPhC-regulated.
Reducing Alcohol to Improve Sexual Health
Cutting down alcohol can improve circulation, energy, hormone balance, and erectile function. Monitoring symptoms while reducing intake can help determine whether alcohol was the main contributor.
