Recent clinical and doctor-patient studies have conclusively proven that psychological impotence directly affects only 10% to 20% of men. However, because of the perceptions men attach to their sexuality and virility, and the subsequent feelings of frustration, Anxiety and Depression caused by Impotence, it can be the indirect result of impotence brought about by a physical condition.

Factors contributing to the issue
Stress
Stress is one of the leading causes of psychological impotence. While a little stress helps drive achievement and success, too much stress is not good for you.  Most of us live fairly stressful lives these days, so stress can be work-related, financial, marital, sexual or any one of a number of other reasons.  

Most men have experienced either a loss of libido or an inability to maintain an erection during periods of stress, however these episodes are usually transient.  In most cases, once the stress has been reduced, full sexual function returns.

Depression
Depression and anxiety disorders are cited as the most common causes of psychological impotence.  However, depression and anxiety can be both the cause and the consequence of impotence. In many cases, it can be very difficult to determine whether depression and anxiety disorders cause impotence, or if impotence leads to feelings of depression and anxiety. 

Clinical depression can cause psychological impotence because it interferes with the brain function necessary to stimulate sexual arousal and produce an erection.  Depression also suppresses positive feelings and emotions, which inhibit libido and the desire for sexual activity.

Relationship Issues
The answer to relationship issues often lies in good communication.  Problems with impotence can put severe pressure on the healthiest relationship, so it's important that both you and your partner share your feelings.

Reducing your anxiety prior to sexual activity is vital.   By working together, you and your partner can enhance your relationship by creating a stress-free, intimate and stimulating environment.

Fatigue
Like stress, fatigue affects us all at certain times and is a common cause of temporary psychological impotence. Fatigue drains mental and physical energy and can result in anxiety if the problem is not addressed.  Like stress, once fatigue is reduced, normal sexuality is restored. On-going fatigue may be a symptom of an underlying medical illness, so consult your doctor if the symptoms persist.
