Physical and Psychological Causes of Erectile Dysfunction

Causes of Erectile Dysfunction


Knowing the causes and treatments of erectile dysfunction requires an in-depth understanding of how erections work and the psychological and physiological factors that bring them about. An erection is part and parcel of the male physiognomy and is caused by increased blood flow through the penis. This increased blood flow is usually caused by either direct contact with the penis or the stimulations of sexual thought. Basically, erections are neurovascular events, which means that the veins, arteries, and nerves all need to function properly for them to occur.

What is Erectile Dysfunction?

Getting an erection is a complex process that involves the peripheral nervous system, the central nervous system, psychological and physiologic factors, vascular (i.e., circulation or blood flow) and hormonal components, as well as local factors within the penis. Erections happen in response to smell, touch, visual or auditory stimuli, any of which may cause the brain to send information to the nerve centers located along the spine’s base. The nerve fibers located here are responsible for the regulation of blood flow before, during, and after erections.

Erectile dysfunction or impotence is the inability to get or sustain an erection long enough for the satisfactory completion of sexual activity. It is a subset of sexual dysfunction and can occur if any of the psychological or physiological processes required to get or maintain an erection is disrupted. The factors that cause erectile dysfunction are classified into two: psychological factors and physiological factors.

Psychological Factors of ED

Some studies show that this is the most common cause of erectile dysfunction, although it usually coexists with other functional or physical causes. Inability to get an erection often produces an emotional and psychological reaction in those affected, and this, in turn, produces a pattern of stress, low self-esteem, and anxiety that further interferes with sexual performance. This is termed “performance anxiety” and should be addressed immediately by your preferred healthcare provider.

Several areas of the brain are involved in sexual behavior, and as such, psychogenic ED may induce the brain to send messages that prevent or inhibit erections. Psychogenic ED may occur due to stressors that cause the release of catecholamines that tighten penile muscles and prevents them from relaxing. Also, feelings such as self-consciousness or nervousness about sex, stress at home or the workplace, troubled feelings, or feelings of insecurity about your sexual relationships can contribute to psychogenic ED.

In such cases, successful treatment will include psychotherapy or psychological counseling for both partners. Medications used in the treatment of psychological issues may also cause ED, and it is advised to consult a physician before discontinuing any medication.

Physical Factors of ED

Physiological erectile dysfunction has been linked to a number of factors such as hormonal imbalance, sleep disorders, or simply a matter of age. From the age of 40 and above, most men will experience some form of ED. They will notice that achieving erections will take more time and effort and sustaining it will become more challenging. Hormonal imbalance is another cause of physiological ED especially in men having pituitary gland problems or having excess estrogen in their system, due to obesity.

Some of the common causes of physiological ED include the following:

  •    High blood pressure and cholesterol
  •    Metabolic syndrome, multiple sclerosis, and Parkinson’s disease
  •    Diabetes and obesity
  •    Peyronie’s disease and sleep disorders
  •    Alcoholism and substance abuse
  •    Enlarged prostate or prostate cancer treatments
  •    Injuries or surgeries that affect the spinal cord or pelvic area
  •    Radiation treatments for cancer
  •    Medications such as antihistamines, antidepressants, and prescription drugs that treat prostate, pain, high blood pressure, etc.

If you have one or more of these underlying conditions, treating them may be enough to reverse ED.

One of the common questions asked by men who experience some form of erectile dysfunction is when they should see a healthcare professional. For individuals who experience ED on occasion, for instance, less than 5 percent of the time, medical attention may not be required. However, if the frequency increases or you experience erection-induced pain, you should seek the help of a medical professional.

    1st visit:I came in to this clinic around February you know just getting ready for valentines day and all.

    Update: Valentines day was amazing! my girlfriend really appreciated my visit to the ezcare walk-in clinic!

    I had a wonderful dinner with my girlfriend and I took the prescribed viagra during our meal and afterwards when it was time for the intimate portion of the day I was ready! I cannot remember the last time i didn’t have the struggle to be intimate. The doctor that helped me was very thoughtful and she put herself in my situation and helped me understand i has low on testosterone and that is why i was having these problems.It’s now May and i am doing so much better! I am truly thankful to this clinic. I go back monthly and i honestly have no problem with it.

    This clinic has saved my marriage! My husband and I walked in about a week ago and since the doctor prescribed him viagra for his erectile dysfunction our intimacy has been great! i can even go as far as to say this clinic practically saved my marriage! Initially both my husband and I were quite scared to try this out because we had heard about all the heart problems it can cause but we decided that if a doctor would monitor it that there shouldn’t be a problem and there wasn’t. He will be going back every month from now on.

    I got this because I was curious and the only way to get an honest answer is to try the product myself. I didn’t want this for anything other than sex.

    I did as the physician said and I first took 1 pill 30 minutes before sex and I felt a bit hot when I first took it, there was no immediate difference, but when it happened… Oh man… It was a good 3 hours.

    I recommend this clinic, get it before Valentines Day for a night you both won’t forget.

    Thanks for helping me understand what erectile dysfunction is. My friends talked to me about how one of our batchmates got the disease and it got me worried. I find it concerning that there are various factors that could cause this for men,e especially sleep disorders since I have sleep apnea. I should share this with my friends as well so that they’re aware of what ED is.
