Causes of Impotence  

Impotence, also known as erectile dysfunction, is defined as a consistent or recurrent penile erection failure in a man which causes him to unable to obtain and / or maintain an adequate and sustainable erection to have intercourse.  It is an anomaly that may occur sporadically or become more regular or even permanent in some cases. However, impotence tends to occur more frequently with age, as well as smoking (tobacco), people consuming alcohol, and overweight individual.

Impotence Causes 


Impotence causes are classified in three main varieties: it is functional impotence, organic impotence and mixed causes.

Pathophysiology - Sexual stimulation causes the release of nitric oxide which is a key mediator to cause an erection.
This release is located and starts from the endothelial cells of the cavernous bodies one part and non- adrenergic non-cholinergic neurons the other. Under control of the P2Y receptors, and within the muscles, the nitrogen monoxide activates guanylate cyclase, which results from a processing of Guanosine triphosphate(GTP) in the cyclic guanosine monophosphate (cGMP ) . The accumulation of cGMP leads, among other things, to relaxation of the smooth muscles of the penile arteries and intra- cavernous tissue, and engorgement of the penis, and thus, ultimately, to erection. Any mechanism or pathology that impairs these functions can cause impotence. 


Psychological causes – nearly 20% of all cases of erectile dysfunction are psychological. Among these Psychological factors include stress, anxiety, guilt, depression, low self-esteem, and indifference from the partner.  


Organic Causes – less than 25% of impotence are due to other diseases: diabetes (50 % of diabetics men over 20 years are impotent), cardiovascular disorder, neurological problems (including paraplegia), high blood pressure, obstruction of the genital arteries (mostly in smokers), harmful effects of alcohol on the nerves causing the erection, consequences of certain forced interventions to cut arteries and nerves (radical prostatectomy or brachytherapy after prostate cancer), hormonal defects, chronic or prolonged disorders, taking certain medications [including Antipsychotics (also known as neuroleptics or major tranquilizers), diuretics, Beta blockers], etc...  

Chronic Alcoholism - Chronic alcoholism or alcohol addiction may be responsible for more than 50% of erectile dysfunction. If you want to please your partner you need to get rid of alcohol from your life.  


Other causes of Impotence 

  • Smoking 
  • Fatigue 
  • Overwork
  • Age - from 50 years, a man often needs more time and stimulation to achieve a satisfactory erection.

Impotence Symptoms

 Erectile dysfunction can manifest as an inability to achieve erection, inability to penetrate the partner or difficulty maintaining a rigid and stable erection during sexuality with, for some men, rapid interruption of erection after penetrating his partner and without being able to ejaculate.
