However, psychological problems also develop with organic erectile dysfunction. According to statistics, vascular causes account for about 70% of etiological factors. Drugs and operations on the pelvic organs - 10% each, neurological disorders - 5%, endocrinological causes - 4% and injuries - 1%.

All Possible Causes of ED in Men

Do you have problems with erection but have no idea why? Check the causes that lead to the impossibility to achieve erection in both young and elederly men.


Psychological disorders include such as:

  • depression,
  • addiction,
  • alcoholism,
  • specific psychopathological disorders - fear of sexual impotence, depleted sexual technique, problems in relations between partners, depression, obsessive states or other psychological problems, etc.

Endocrine disorders

Libido (sexual desire) and the ability to erection in a man depends on the level of male sex hormones (androgens). These hormones are produced in Leydig cells located in the tissue of the testes. The release of androgens by the central links of the endocrine system - the pituitary and hypothalamus - is regulated.

A decrease in the level of androgens is observed in the following conditions:

  • hypogonadism (hypoplasia reduction of the function of the sex glands, including anorchism, cryptorchism);
  • male menopause (age-related decline in the function of the gonads); castration (removal of the testicles due to trauma, testicular cancer, or other conditions requiring removal); prolactinoma (pituitary tumor that secretes the hormone prolactin, which inhibits the activity of the testes);
  • increase in the level of female sex hormone — estradiol; the use of certain drugs that reduce the level of androgens (stilbestrol, etc.);
  • tumor and non-tumor damage to the brain areas responsible for the regulation of testicular function (acromegaly);
  • sarcoidosis with lesions in certain areas of the brain; diabetes; adrenal gland diseases (Addison's disease, adrenal tumors);
  • chromophobic adenoma,
  • craniopharyngioma,
  • Cushing's syndrome.

Less frequent causes in this category include eunuchoidism (including Kleinfelter syndrome), feminizing interstitial cell tumor, Fröhlich syndrome, myxedema, obesity, Lawrence-Muna-Bidla syndrome, pituitary insufficiency, pituitary insufficiency, idiopathic insufficiency, pituitary insufficiency, and heart failure, idiopathic insufficiency, pituitary insufficiency, inactivity, and pituitary insufficiency, iydroma, and pituitary insufficiency, idiopathic heart failure.

Vascular or Vasculogenic Erectile Dysfunction

Blood flow disturbance occurs because of the following reasons:

  • Atherosclerosis of the blood vessels of the penis - the formation of atherosclerotic plaques in the artery wall. Predisposing factors: hypertension, hyperlipidemia (high fat in the blood), smoking, alcoholism, diabetes, hypothyroidism (decreased thyroid function), obesity.
  • Blockage of the pelvic arteries, as a result of pelvic bone fractures.
  • Violation of blood circulation in the vessels of the penis (penile angiospasm), as a result of smoking, taking certain medications.
  • Impaired function of the venous system of the penis.
  • A combination of different reasons: aortic aneurysm, obstruction of the ileal arteries, Leriche syndrome, priapism, violation of venous outflow (venous insufficiency) as a result of a violation of the valve mechanism, the blood quickly leaves the cavernous body and the erection cannot reach its maximum.

Neurological Disorders Leading to ED

The neurological disorders are one of the most common problems in men. Check what they are:

  • violation of cerebral circulation (stroke)
  • hypothalamic tumors
  • Alzheimer's disease
  • damage to the temporal lobes
  • paraplegia
  • diseases of the spinal cord (amyotrophic lateral sclerosis, compression of the spinal cord, multiple sclerosis, syringomyelia, tumors and injuries of the spinal cord, tabes dorsalis,
  • peripheral neuropathy (toxic)
  • Parkinsonism
  • Shai-Drager syndrome


ED Causes

Surgical causes of ED may be as a result of a violation of innervation. They are listed below:

  • abdominal-anal resection - removal of the rectum for colorectal cancer or cancer of the anal canal
  • aneurysmectomy - removal of the aneurysm (dilation of large blood vessels)
  • aorto-iliac reconstruction - restoration of blood flow in the blood vessels of the abdominal cavity, small pelvis and lower extremities
  • external sphincterotomy - dissection of the sphincter of the rectum
  • radical resection of the rectum and sigmoid colon
  • cystectomy - removal of the bladder
  • retroperitoneal lymphadenectomy - removal of retroperitoneal fat, usually due to its metastatic lesion, lymphosarcoma, liposarcoma, and other tumors
  • lumbar sympathectomy - the intersection of sympathetic trunks in order to improve blood flow in the vessels of the lower extremities
  • removal of the temporal lobe - removal of the lobe of the brain due to a tumor or traumatic injury.

ED as a Complication of Drug Therapy

If you notice a decrease in potency while taking these drugs, do not interrupt the treatment yourself. Consult your doctor about the possibility of changing the drug or changing the dose.

  • Antihypertensive drugs
  • Diuretics
  • Hypolipidemic drugs (drugs to lower blood lipids)
  • H2-blockers
  • Antipsychotic drugs (Barbiturates, Bromides, Chlordiazeposide, Chlorprothixen, Fenothiazines, Reserpine, Imipramine).
  • Antidepressants (Tricyclic antidepressants, MAO inhibitors, Serotonin inhibitors, Lithium preparations).


In most cases, a man suffering from ED has more than 1 cause at a time. The general bad health condition always leads to the decrease in men's sexual power. So you need to take care of your health both physical and psychological if you want to enjoy sexual life as long as possible.
