What is erectile dysfunction (ED)?
Erectile dysfunction (ED), sometimes referred to as impotence, is a common condition where a man has difficulty getting or keeping an erection firm enough for sexual activity. ED can affect men of all ages, although it becomes more common with increasing age. It can be a short-term problem or a longer-term condition depending on the underlying cause.
Occasional difficulty with erections is not usually a cause for concern. However, ongoing or worsening erectile problems may require medical assessment.
Common causes of erectile dysfunction
Erectile dysfunction can have physical, psychological, or lifestyle-related causes. In many cases, more than one factor may be involved.
Physical causes
Physical causes of ED often affect blood flow, nerve supply, or hormone levels. Common physical causes include:
- Reduced blood flow to the penis due to narrowed blood vessels
- Diabetes
- High blood pressure or heart disease
- High cholesterol
- Hormonal conditions, such as low testosterone
- Nerve damage following surgery or injury
- Certain prescription medicines
Psychological causes
Psychological factors can play a significant role in erectile dysfunction, particularly in younger men. These may include:
- Stress or anxiety
- Depression
- Relationship difficulties
- Performance anxiety
- Low self-confidence
- Psychological causes may occur on their own or alongside physical conditions.
Lifestyle factors
Lifestyle habits can also contribute to erectile dysfunction, including:
- Smoking
- Excessive alcohol consumption
- Being overweight or obese
- Lack of physical activity
- Poor sleep patterns
- Recreational drug use
- Making positive lifestyle changes can help improve erectile function in some men.
Symptoms and when to seek help
The main symptom of erectile dysfunction is difficulty achieving or maintaining an erection. Some men may also notice:
- Reduced sexual desire
- Less firm erections
- Difficulty maintaining erections during sexual activity
You should consider speaking to a healthcare professional if erectile problems:
- Persist for several weeks or months
- Occur frequently
- Are affecting your wellbeing or relationships
How erectile dysfunction is diagnosed
Erectile dysfunction is usually diagnosed based on your medical history and symptoms. A healthcare professional may ask questions about:
- Your general health
- Any existing medical conditions
- Medicines you are taking
- Lifestyle factors
In some cases, blood tests or other investigations may be recommended to check for underlying conditions such as diabetes or hormonal imbalance.
Treatment options for erectile dysfunction
Treatment for ED depends on the underlying cause and individual circumstances. Several options may be available.
Lifestyle changes
For some men, lifestyle changes may improve erectile function. These can include:
- Stopping smoking
- Reducing alcohol intake
- Increasing physical activity
- Maintaining a healthy weight
- Improving sleep quality
- Managing stress
PDE5 inhibitors (sildenafil, tadalafil)
Medicines known as PDE5 inhibitors are commonly used to treat erectile dysfunction. These include:
- Sildenafil (generic Viagra)
- Tadalafil (generic Cialis)
These medicines work by increasing blood flow to the penis when a man is sexually stimulated. They do not cause an erection on their own and require sexual arousal to be effective.
A medical consultation is required to ensure these treatments are safe and suitable for you.
Other treatments
If tablet treatments are not suitable or effective, other options may be considered, including:
- Vacuum erection devices
- Injection treatments
- Hormone treatment (if appropriate)
- Psychological therapy or counselling
A healthcare professional can advise on the most appropriate option.
Safety: when ED tablets may not be suitable
Erectile dysfunction tablets may not be suitable for everyone. They should not be taken by individuals who:
- Use nitrate medicines for chest pain
- Take riociguat
- Have certain heart or blood pressure conditions
- Have been advised to avoid sexual activity for medical reasons
A medical consultation is essential before treatment is supplied.
