Diseases and disorders such as arteriosclerosis, diabetes, or a blood clot that narrow arteries and decrease blood inflow are the leading cause for ED
. Also surgery on the blood vessels can cause Erectile Dysfunction
along with abnormalities in the veins of the penis that allow the blood to flow backwards into the body so rapidly that an erection can not be adequately sustained even though there is sufficient blood flood.
Surgeries such as prostate, back or spine surgery, and other diseases such as spinal disease, multiple sclerosis, and peripheral nerve disorders can cause the ED
to be a neurological problem. The nerves leading to or from the penis could be damaged with the surgical procedure. Drug abuse and excessive alcohol consumption effects blood flow and can also be a contributing factor to ED. Stroke and occasionally a low testosterone level or hormone imbalance can be a cause of ED
. Also, a man’s energy level can affect an ability to sustain a full erection. Things such as fatigue, illness, stress and depression are some of the more common causes. “Many drugs can interfere with the ability to achieve an erection, especially among older men. Drugs that commonly cause erectile dysfunction include Antihypertensives, Antidepressants, some Sedatives, Cimetidine (Tagamet), Digoxin (Lanoxin), Lithium (Lithane, Lithonate) and Antipsychotics.
Psychological issues (such as depression, performance anxiety, guilt, fear of intimacy, and ambivalence about sexual orientation) can impair the ability to achieve erections. Psychological causes are more common in younger men. Any new stressful situation, such as a change of sex partners or problems with relationships or at work, can also contribute.” 2
