Erectile Dysfunction

Erectile dysfunction information including causes, symptoms and treatment

Erectile dysfunction (ED), also known as impotence, is a common condition that affects millions of men around the world. In the UK alone, it is estimated that 2.3 million men currently have ED, and as many as one in ten men are expected to experience the condition at some point in their lives. Although it is often seen as a condition affecting older men aged between 40 and 70, it isn't uncommon for many younger men to also experience ED due to issues such as stress and anxiety as well as physical inclinations.

Fortunately, thanks to the invention of highly effective erectile dysfunction treatments, this condition can be managed effectively with the correct medication after a doctor's prescription. At OnlineClinic, our UK registered doctors provide effective prescription medications, which you can compare here, or continue to read on for further information.

What is erectile dysfunction?

Erectile dysfunction (impotence) is defined as the inability to achieve or sustain an erection, in order to be able to complete sexual intercourse or other forms of sexual activity with a partner. Erectile dysfunction is essentially caused by a lack of blood flow through the penis, meaning an erection can't form. Although erectile dysfunction can occur at any age, it is most common in older men, between the ages of 40 and 70.

Erectile dysfunction is a common problem but so many can go years without seeking help in the form of doctor's advice and information, looking into treatment options or speaking with their partners due to a number of reasons. However, this is now being addressed with the awareness surrounding the condition and the popularity of available impotence treatments, such as Viagra and Cialis.

As well as medications and causes of ED being more openly reviewed, awareness via public campaigns, helplines and an increase in the availability of information and advice through the national health service (NHS) and health organisations has helped significantly lower the taboo of erectile problems. The Sexual Advice Association is a good example of this.

Erectile dysfunction causes

Erectile problems can be caused by numerous factors that can stem from physical and psychological issues, daily lifestyle habits, or even a combination of all. Whilst the cause of the condition is dependant on the individual, it's estimated by doctors and other professionals that 75% of all long-term impotence cases result directly from physical problems, with psychological and lifestyle factors accounting for most short-term erectile problems.

Men with physically-induced erectile dysfunction often find that they gradually lose the ability to have an erection. It is estimated that 8 out of 10 impotence cases are physically induced, which can be caused by:

  • Diabetes
  • Hardening of the arteries
  • Heart, liver or kidney problems
  • Cerebral or spinal cord injuries
  • Abdominal, pelvic or prostate surgery
  • Side effects of various medications
  • High blood pressure or high cholesterol
  • Multiple sclerosis or other neurological diseases

However, some men who suffer from erection problems can still achieve an erection, albeit inconsistently. This is often the result of psychological causes that may include:

  • Relationship problems
  • Guilt
  • Depression
  • Sexual boredom
  • Routine stress and anxiety
  • Exhaustion
  • Performance anxiety
  • Unresolved sexual orientation

Moreover, various lifestyle choices and habits that may be the cause of erectile problems include:

  • Smoking
  • Stress
  • Excessive alcohol consumption
  • Obesity
  • Recreational medication use

Regardless of the cause or combination of causes, you can be offered treatment and further information from your doctor to help treat ED.

Erectile dysfunction symptoms

The main and most common symptom is the inability to achieve and sustain an erection. If you find that you lose your erection before or during penetration, then you could be suffering from erectile dysfunction. If you experience this issue of being unable to achieve or maintain an erection several times within a short period of time, then it would be advised to seek further medical help and treatment if required. However, in regards to losing an erection, some men confuse this with premature ejaculation, which is a separate condition with its own treatment.

Other symptoms revolve around psychological factors this can cause including stress, anxiety and depression.

Treating erectile dysfunction

As medical advancements continue to be made, there are more and more treatments being developed and help on-hand available to suit the needs of men who suffer from erectile dysfunction.

Prescription medication

At OnlineClinic, we stock Viagra, Cialis, Sildenafil and Levitra as well as newer medication Spedra and an Impotence Trial Pack that includes four of the most popular treatments if you're unsure which is the right tablet for you. These prescription medications are taken orally in the form of a tablet and are widely regarded as the most popular and effective form of treatment for erectile dysfunction. These medications can be used for both short-term and long-term treatment with varying dosages and strengths available. When obtaining treatment online, a short consultation will give our doctors the essential information needed to issue the correct medication as well as dosage. The Impotence Trial Pack contains Viagra, Cialis and Levitra.

Other forms of treatment can include the following:


If the root of your erection problem is psychological, then counselling can be a suitable solution. Therapy has been used as a successful method in helping to re-establish sexual relationships, especially for couples who have not had sex for a long period of time. This can be an effective option when used alongside prescription medication as well.

Vacuum pumps

Although they cannot treat erectile dysfunction, vacuum pumps can be used to help you enhance your sexual performance. These devices have a plastic cylinder and pump, which when used, will help blood to flow to the penis and help to achieve an erection. There currently isn't any decisive evidence to prove the efficiency of vacuum pumps when used to treat male impotence. The effects are only temporary and it can come with some risk. It is recommended that you should seek medical assistance from your doctor prior to using vacuum pumps.


This is only required under extreme circumstances and is regarded as a 'last resort' method. This kind of surgery can be provided by the NHS. Cosmetic operations can also be performed, including a penile implant. However, these operations aren't available on the health service.

Preventing erectile dysfunction

There are a number of tips you can follow in order to effectively prevent erectile dysfunction. These are as follows:

  • Lose weight – excess weight can put strain on the cardiovascular system
  • Maintain a healthy and well-balanced diet
  • Quit smoking – ensures a correct blood flow to the penis
  • Avoid excessive alcohol consumption
  • Closely monitor blood pressure and cholesterol levels
  • Exercise regularly
  • Getting treatment for mental health concerns (e.g. depression or anxiety)
