Erectile Dysfunction

Erectile dysfunction is also known as 'impotence', and refers to a man's failure to develop an erection. This dysfunction is generally regarded as a medical complaint, although there are potentially a number of psychological reasons for the problem and tiredness can often be a factor.

 

As a rule, erectile dysfunction is considered to have a medical cause when the sufferer is unable to develop an erection during sex and no longer develops erections while sleeping or in the mornings. Common medical causes of erectile dysfunction include diabetes, cardiovascular disease, reduced testosterone levels and side effects of using anti-depressants. Heavy drinking and alcoholism are also known to increase the risks of impotence. Most men suffering from erectile dysfunction are found to have a generally low level of health and fitness, and are often overweight.

 

Whether erection occurs as a result of physical or mental stimuli, the neural system is key to ensuring its development and maintainance. Testosterone levels and healthy pituitary glands are also required. While the inability to develop an erection can be caused by stress, worry and even tiredness, the complete inability to ever develop an erection is often the symptom of a medical problem affecting the neural system, testosterone levels or abnormal hormonal activity.
