Impotence is not a disease but it signals that something is not correct with-in the body. It is caused gradually and there are a number of factors that cause impotence. Some of the physical causes of impotence are listed below.

Cardiovascular Diseases

Impotence occurs when the nerves that control blood flow to the penis are damaged. Hardening of arteries also results in inability to achieve erection. The blood required for an erection is not delivered appropriately because of the hardening of arteries. When the pelvic organs and the arteries to the penis are narrowed by atherosclerosis, blood required for erection is not delivered sufficiently. The insufficient supply of blood results in inability to achieve erection or inability to maintain erection for sexual intercourse.

Aging

Old men are more likely to experience erectile dysfunction when compared to young men. The compliance of the tissues present in corpora cavernosa decreases with age and this results in inability to maintain erection. Also, old men usually develop diseases that are associated with erectile dysfunction. Diabetes mellitus, strokes, heart attacks, angina are some of the diseases that are associated with erectile dysfunction.

Cancer Surgery

Sometimes, impotence is also caused because of the damage caused to the nerves during surgery. Damage caused to blood vessels during surgery also causes impotence. So, it's very important to make sure that nerves and blood vessels are not damaged while removing the tissues that cause cancer.

Injuries

Damage to nerves in the pelvis also causes potency problems. Spinal cord injuries can also cause impotence. The damage to nerves is usually caused by accidents, diseases, and during surgical procedures.

Hormone Imbalance

Hormone imbalance also results in potency problems. Abnormal testosterone levels cause potency problems. Illnesses like kidney failure also disrupt the balance of hormones in body and the imbalance can cause problems in maintaining and achieving erection. However, it's rare to find people facing potency problems because of hormone imbalance.

Medication

Sometimes, temporary impotence is caused because of some medicines. Medicines that interfere with nerve impulses cause erectile dysfunction. Usually, medicines used for treating high blood pressure, antidepressants, antihistamines, tranquilizers affect blood flow to the penis. The interference with blood flow to the penis causes potency problems.

Diabetes Mellitus

Impotence is caused when the blood vessels or nerves that control the flow of blood to the penis are affected. Diabetes causes nerve deterioration and this is the reason why many diabetes patients face potency problems. Diabetic men are more prone to impotence than non-diabetic men. Diabetes also damages sensory and autonomic nerves, and this causes erectile dysfunction. In diabetic men, the arteries get affected and this results in insufficient supply of blood to the penis. The insufficient supply of blood to the penis results in inability to maintain erection.
