Erection problems are common and can affect men at any age. Erectile dysfunction becomes more common after the age of 40, although younger men can experience it too. It means repeatedly having difficulty achieving or maintaining an erection firm enough for sex. The problem can also lead to stress and performance anxiety, which may make matters worse.
What are the most common causes of erection problems, and which treatments can help?
No, treatment options are not limited to Viagra.
In this article, we look at the causes of erectile dysfunction, the signs to be aware of, how the condition is diagnosed and the treatments that may be available. The aim is to give you a clear overview of the condition and explain the practical steps you can take.
How an erection occurs:
What Causes Erectile Dysfunction?
What causes erectile dysfunction? In many cases, there is a physical reason connected with an underlying health condition. Common causes include:
- problems affecting the blood vessels;
- conditions affecting the nerves;
- hormonal imbalances;
- psychological factors;
- side effects from certain medicines.
Psychological factors can also play an important part, particularly in younger men. These may include depression, stress and performance anxiety, relationship difficulties or a previous negative sexual experience. Sometimes the problem begins for a physical reason and is then reinforced by anxiety about whether it will happen again.
Age is a relevant factor because conditions that affect circulation, nerves and hormone levels become more common over time. However, erectile dysfunction should not simply be dismissed as an unavoidable part of getting older.
Factors that can increase the risk of erectile dysfunction include:
- smoking;
- drinking too much alcohol;
- recreational drug use;
- being overweight or physically inactive;
- long-term stress and poor sleep.
Health conditions associated with erectile dysfunction include:
- atherosclerosis and other circulation problems;
- diabetes;
- cardiovascular disease;
- prostate conditions or treatment for prostate cancer;
- chronic lung disease;
- kidney or liver disease;
- neurological conditions.
Other Possible Causes of Erectile Dysfunction
An erection depends on healthy blood flow, functioning nerves, suitable hormone levels and sexual arousal. If the blood vessels cannot carry enough blood into the penis, or if blood leaves it too quickly, achieving or maintaining an erection may become difficult.
Frequent smoking and heavy alcohol use can damage circulation over time and increase the likelihood of erection problems. A wide range of prescription medicines can also cause erectile dysfunction as a side effect, including some treatments for high blood pressure, depression and other long-term conditions. Never stop taking prescribed medicine without speaking to your doctor; they may be able to adjust the dose or suggest an alternative.
What Are the Symptoms of Erectile Dysfunction?
The main symptoms of erectile dysfunction are:
- difficulty achieving an erection;
- difficulty keeping an erection long enough for sex;
- erections that are not firm enough for penetration;
- a noticeable and persistent change from your usual erectile function.
Other changes, such as reduced sex drive, tiredness, weight changes or signs of a hormonal imbalance, may point to an underlying condition rather than being symptoms of erectile dysfunction itself. High blood pressure, diabetes and cardiovascular disease may also be discovered during an assessment.
Some prostate or bladder cancer treatments can affect the nerves and blood vessels involved in erections. Recovery may take several months, and specialist support can be helpful. Injuries involving the pelvis, spinal cord, bladder or penis can also affect erectile function.
Hormonal conditions, including low testosterone or thyroid problems, may reduce sexual desire or contribute to erection difficulties. Depending on your symptoms, a doctor may recommend blood tests to investigate possible hormonal, kidney, liver or metabolic causes.
Medicines used for erection problems include:
- Sildenafil citrate, a PDE5 inhibitor and the active ingredient in Viagra;
- Vardenafil, the active ingredient in Levitra;
- Tadalafil, a longer-lasting PDE5 inhibitor used in Cialis;
- Avanafil, a faster-acting PDE5 inhibitor used in treatments such as Spedra.
Dapoxetine is used for premature ejaculation, not erectile dysfunction, although the two problems can sometimes occur together.

How Is Erectile Dysfunction Diagnosed?
If you are concerned about your erections, an online IIEF questionnaire can help you describe the problem, but it cannot replace a medical assessment.
A doctor will usually ask about your general health, medicines, lifestyle, relationships and sexual history. Depending on the circumstances, they may also check your blood pressure, examine you and arrange blood tests. Because erectile dysfunction can sometimes be an early sign of diabetes or cardiovascular disease, it is worth taking persistent symptoms seriously rather than simply treating them in isolation.
How Is Erectile Dysfunction Treated?
Erectile dysfunction can be treated in several ways, and the best option depends on its cause, your general health and your preferences.
Treatments may include medicines such as Viagra, Cialis, Cenforce and Levitra. PDE5 inhibitors improve blood flow to the penis during sexual stimulation. They do not create sexual desire or cause an automatic erection.
Lifestyle changes can make a meaningful difference, especially when circulation or general health is involved. Stopping smoking, reducing alcohol, being physically active, improving sleep and managing weight may all support erectile health.
Other options include vacuum erection devices, injections or urethral medicines. Surgery, usually involving a penile implant, is normally considered only when less invasive treatments have not worked or are unsuitable.
When anxiety, depression or relationship difficulties are contributing to the problem, counselling or sex therapy may help. An open conversation with your partner can also reduce pressure. Medicines such as Viagra, Cialis and Levitra may improve confidence when they are medically suitable, but they do not address every psychological or relationship factor on their own.
