Erectile dysfunction (ED) is a common condition affecting over 50% of men between 40 and 70 in the UK. While the likelihood of experiencing ED does increase with age, it can affect men from any age. Caused by a variety and combination of factors such as lifestyle, psychological, physical. Yet, despite it being such a common condition, many men still delay seeking treatment, suffering in silence when they don’t need to.
By understanding this symptom, it can be easier to prevent it from occurring in the first place, and easier to seek the right treatment in order to help.
What is Erectile Dysfunction?
Erectile dysfunction is defined as when a man has difficulty getting or maintaining an erection firm enough for sexual activity. It can happen from time to time because of factors such as short-term stress or tiredness, but consistent difficulty can be a sign that treatment is needed.
How Erections Work
An erection is a complex biological process involving the brain, nerves, hormones, and blood vessels to all work together in a quick chain of events. Beginning in the brain, where sexual thoughts or stimulation triggers arousal, then travelling through the nervous system to the penis. Nerves are triggered to release a chemical called nitric oxide, which helps by relaxing the muscles in penile tissues, widening blood vessels and increasing the blood flow to the penis achieving an erection. As blood rushes to the area, the surrounding veins compress, helping to maintain the erection.
For this all to work smoothly, all of the systems involved need to be working together seamlessly.
This includes:
- Brain – To initiate arousal
- Hormones – Which influence libido and maintains healthy penile tissue
- Nerves – Which transmit signals through the body
- Blood vessels – To regulate blood flow
A disruption to any of these elements can affect the ability to achieve and maintain an erection.
How Common is Erectile Dysfunction?
ED is more common than many people realise. Although it can happen from time to time to any man, ongoing difficulties can become more likely with age. However, while ED does affect a higher percentage of men over 40 years old, around 29% of men under 40 are also suffering from ED to some degree.
Studies have found that cases of erectile dysfunction are rising, especially within younger men. Likely due to changes in lifestyle factors, technology, and sexual behaviours which could be contributing to the rise.
The Main Causes of Erectile Dysfunction
Erectile dysfunction can results from a wide range of physical, psychological, and lifestyle factors. And often, ED might not be caused by one single issue, but a complex combination of influences working together.
Physical Health Conditions
Certain underlying health conditions can cause erectile dysfunction due to their effect upon blood flow, nerve function, or hormonal levels; all of which are key in erectile function.
Common conditions which can cause erectile dysfunction are:
- Diabetes
- Heart disease
- High blood pressure
- Hormonal issues (such as low testosterone which can reduce libido)
Psychological Causes
Our brains play a crucial role in sexual arousal. This means maintaining good mental and emotional health is important for erectile function and overall health too. If your mental health is affected with daily stressors, emotional disconnects with a partner, or performance related anxieties, these can interfere with sexual performance.
Common phycological causes of ED can include:
- Stress
- Anxiety
- Depression
- Relationship and mental health effects
Lifestyle Factors
Everyday habits while you may think unrelated to erectile function, can have a huge part to play. Over time, certain lifestyle choices can lead to damaged blood vessels, reduced testosterone levels, or negatively impact overall health.
Some key factors which can contribute to erectile dysfunction include:
- Smoking
- Excessive alcohol intake
- Obesity
- Poor sleep
Medications That Can Cause Erectile Dysfunction
Some medications have been found to impact sexual function as a side effect. This is usually due to the medication’s effect on hormone levels, nerve signals, or blood flow.
Common examples of medications which can lead to ED include:
- Antidepressants (SSRIs) which can reduce libido, delaying or sometimes preventing erections from happening.
- Blood pressure medications which can reduce blood flow throughout the body, including to the penile area.
- Antipsychotics can affect dopamine levels in the body, leading to an effect upon arousal.
- Hormone treatments which can alter testosterone levels; the key hormone in erectile function.
If you think that your medication might be altering your sexual health, you should never stop taking it suddenly without first speaking to a healthcare professional. They can work with you to find an alternative which can support your sexual health as well as your physical health.
The Emotional and Mental Health Impact of ED
Erectile dysfunction is not just a physical issue, but can also have a significant emotional impact. Affecting confidence, self-esteem, causing relationship strain, and affecting overall mental health.
Many might experience embarrassment or frustration when dealing with ED, which can often cause a cycle as anxiety and stress can make this issue worse.
It’s important to remember that erectile dysfunction is a common condition with effective treatment options available.
Porn, Performance Anxiety, and Modern Pressures
Erectile dysfunction is not a modern problem, but in the modern world, the number of cases is rising leading to many to draw the link between modern pressures and rising cases. Ideas surrounding modern sexual habits, and expectations might be influencing erectile dysfunction, especially in younger men.
Porn related ED
There’s growing evidence that the rising consumption of pornography, particularly amongst younger men, may be causing a desensitisation to real-life sexual experiences. This is known as porn-induced erectile dysfunction (PIED). One recent study found a notable increase in ED in younger men who frequently consumed pornography. This link may be due to to unrealistic expectations or reduced sensitivity with real-life partners.
Expectation
There has been a shift in what we expect of men in modern society. Expectations around masculinity, relationships, and sexual performance have shifted. An enormous pressure is placed on men to conform to ‘ideals’ of masculinity created by media and pop culture. And, overthinking how well you’re conforming to these unrealistic ideals can often lead to the very anxieties and stresses which can cause erectile dysfunction.
Stigma
Perhaps one of the most significant barriers to addressing ED in the modern world is the stigma still surrounding it. Many men are reluctant to discuss sexual health issues, worried they will be judged or ridiculed. This silence can prevent them from seeking help, perpetuating a cycle of shame and isolation. Breaking this stigma is crucial. ED is a common and treatable condition, and there’s no shame in seeking support.
Erectile Dysfunction by Age
The likelihood of experiencing ED increases with age, particularly if over the age of 40. But, it is not an inevitable part of aging and it’s not certainly going to affect all men as they age. However, there are some age-related changes which can contribute to erectile dysfunction.
Signs Your ED May Be Physical Vs Psychological
One way of understanding your ED is by working out if the main causes are physical or psychological, or a combination of both.
Signs ED is Physical
- You are over 50 and it has gradually gotten worse.
- You are no longer getting morning erections.
- You have another health condition such as high blood pressure or diabetes.
- You have habits such as smoking, or an unbalanced diet.
Signs ED is Psychological
- You may still get morning erections or masturbation erections.
- ED occurs suddenly, during periods of high stress.
- You feel anxious about your performance in the leadup.
- You are having any relationship problems.
Can Erectile Dysfunction Be a Warning Sign?
Yes, sometimes. Erectile dysfunction can be an early warning sign of a more serious health condition such as heart disease or diabetes. Blood vessels in the penis are smaller than those in other parts of the body, which means they can show signs of reduced blood flow earlier than other parts of the body.
In some cases, ED can appear years before other symptoms of heart disease, meaning that it is not a symptom to be ignored.
How is Erectile Dysfunction Diagnosed?
Diagnosing erectile dysfunction usually involves a combination of looking through medical history, targeted testing, and discussing with a healthcare professional what exactly is happening. Sometimes a clinician may request a blood test, or a hormone test just to get the bottom of what might be causing your symptoms. After a clinician has discovered a likely cause, they can discover a suitable treatment option.
How is Erectile Dysfunction Treated?
Erectile dysfunction is very treatable, with many men seeing a significant improvement with the right approach. The trick is finding the right treatment option for you.
Medication for ED
The most common medications for ED include sildenafil (Viagra) and tadalafil (Cialis), which work by increasing blood flow to the penis, making it easier to achieve and maintain an erection.
Other options can include, hormone therapy which can be effective for men with hormonal imbalances, particularly low testosterone.
Vacuum erection devices can be used which involves placing a tube over the penis, and using a pump to create a vacuum that pulls blood into the penis. Then applying a ring at the base of the penis to maintain the erection.
In severe cases, surgical options such as penile implants or vascular surgery can be considered.
Lifestyle Changes
- Exercise regularly: Engaging in regular physical activity improves cardiovascular health, which is crucial for erectile function. Exercise also helps in maintaining a healthy weight and reducing stress.
- Healthy diet: A diet rich in fruits, vegetables, wholegrains, and lean proteins can help improve ED by enhancing heart health and reducing obesity.
- Quitting smoking and limiting alcohol: Both smoking and excessive alcohol consumption are linked to ED. Quitting smoking and moderating alcohol intake can significantly improve erectile function.
- Stress management: Techniques such as mindfulness, meditation, and therapy can reduce stress and anxiety, addressing the psychological causes of ED.
Psychological and Counselling Support
- Therapy: For those whose ED is rooted in psychological factors, counselling or sex therapy can be highly effective. Couples therapy may also be beneficial in addressing relationship issues contributing to ED.
- Lifestyle Coaching: Professional guidance in making lifestyle changes can enhance the effectiveness of other treatments.
Alternative treatments
- Acupuncture: Some studies suggest that acupuncture can help in treating ED, though evidence is mixed.
- Herbal and natural remedies: Supplements such as ginseng and L-arginine have been explored for ED treatment, but it’s important to consult with a healthcare provider before trying these options, as they can interact with other medications.
When to Speak to a Doctor
Seek medical advice regarding your erectile dysfunction if you experience any of the following:
- Sudden onset erectile dysfunction
- ED alongside chest pain or shortness of breath
- Symptoms of diabetes (such as increased thirst or frequent needing to urinate)
- ED following a pelvic injury

Erectile Dysfunction FAQs
What causes erectile dysfunction?
ED’s aetiology is multifaceted, with a blend of physical and psychological components:
Psychological Causes: Mental health conditions, including depression, anxiety, or past traumas, can wield a powerful influence. Modern lifestyles, laden with stress and rapid pace, have exacerbated ED incidences. Furthermore, relationship issues, from miscommunication to distrust, can instigate or exacerbate ED.
Types of Erectile Dysfunction
As we dive deeper, we discover that ED isn’t a one-size-fits-all condition. It manifests in different ways, and understanding these variations is foundational to grasping its full scope.
Primary Erectile Dysfunction: In this type of ED, men have never been able to sustain an erection. It’s relatively rare and often roots more deeply, possibly in severe psychological issues or congenital abnormalities.
Secondary Erectile Dysfunction: This includes men who previously had no trouble achieving and maintaining erections but now find it challenging. It’s the most prevalent form of ED and can be triggered by a myriad of factors.
The distinction between these two types is more than academic. It affects the experience of the individual, potential interventions, and the prognosis of the condition.
What erectile dysfunction treatments are available?
The UK boasts an array of medications, evidence of the advanced biomedical research and healthcare commitment:
Sildenafil (Viagra): Pioneering the revolution against ED, Viagra enhances nitric oxide effects, a crucial compound for penile blood flow. Its efficacy is well-documented, but patients must be wary of potential side effects like headaches or vision changes.
Tadalafil (Cialis): Its longevity, lasting up to 36 hours, has earned it the moniker “weekend pill.” Ideal for men desiring flexibility.
Vardenafil (Levitra) and Avanafil (Spedra): These offer varied durations and onset times, catering to specific needs.
Beyond pills, there are other interventions:
Vitaros Cream: A novel approach where alprostadil, a vasodilator, is applied directly, offering an alternative for those wary of oral medications.
Vacuum Pumps: While mechanical, their efficacy is commendable. Through creating a vacuum, blood is drawn into the penis. A constriction ring then maintains the erection.
Psychotherapy: For men where the mind is the primary barrier, therapy can unravel deep-seated fears or misconceptions, providing a holistic healing approach.
What lifestyle changes can I make to help with erectile dysfunction?
ED is often a symptom of broader lifestyle issues:
Diet and Exercise: The Mediterranean diet, replete with whole grains, fruits, and olive oil, has been linked to improved ED symptoms. Additionally, regular physical activity, especially cardiovascular exercises, can enhance blood flow and overall health.
Alcohol and Tobacco: Both are vasoconstrictors, impeding blood flow. Limiting or eliminating their consumption can bear significant benefits.
Stress Management: Techniques like mindfulness, meditation, or yoga offer sanctuaries from the relentless pace of modern life, ensuring mental tranquillity.
