What Causes Erectile Dysfunction?
An erection occurs when the penis fills with blood, and the blood is not allowed back out by certain muscles in the penis. For this process to occur, a whole set of interrelated events and conditions is required. Disruption of any element or condition can cause erectile dysfunction, otherwise known as impotence. An erection starts with a stimulus in the brain, which sends nerve impulses to the penis. If the nerves, blood vessels, muscles, and fibrous tissues in the penis are healthy, it produces a response, which triggers an erection. However, if they are damaged from injury, disease, or malfunction, it often leads to erectile dysfunction or the inability to achieve an erection. In the past, it was believed that erectile dysfunction was mainly caused by psychological problems. Today however, most experts agree that 85% of impotence cases are a result of physical factors. Below is a list of possible causes of impotence.
Diabetes Mellitus Impotence is very common among men with diabetes. In fact, about 60% of all men with diabetes experience impotence. This is due to the fact that when blood sugar levels are high, it often does damage to small blood vessels and nerves throughout the body. Including those in and around the penis. As a result, the proper nerve function and blood flow needed to achieve an erection is hindered.
Vascular Disease Vascular diseases, such as arteriosclerosis cause a reduction in blood flow to the heart, brain and other parts of the body. As a result, it can often lead to impotence. Vascular disease is common among men over 60 years of age. Other risk factors of vascular disease include the following: high blood pressure, high cholesterol, and smoking.
Venous Leak Venous leak occurs when the veins in the penis cannot hold blood to maintain an erection. Venous leak can be a result of injury, disease, or damage to the veins in the penis.
Neurologic Causes Spinal cord and brain injuries (including paraplegia and stroke) can cause impotence when they interrupt the transfer of nerve impulses from the brain to the penis. Other nerve disorders, such as multiple sclerosis, Parkinson's disease and Alzheimer's disease may also contribute to impotence.
Drug-related Impotence There are over 200 prescription drugs can directly cause or contribute to impotence. Among these are drugs for high blood pressure, heart medications, antidepressants, tranquilizers and sedatives. Over-the-counter medications can lead to impotence as well, in addition to non-prescription recreational drugs such as alcohol and/or illegal narcotics. Remember, if you suspect drug-related impotence, do not discontinue taking your medications without first consulting your doctor.
Hormonal Imbalances Hormonal disorders, such as low testosterone levels, account for less than 5% of all impotence cases. Testosterone deficiency can result from an excess amount of Prolactin in the body. Prolactin is a hormone that's produced by the pituitary gland. When levels of Prolactin are high, it's a good indication there are tumors growing inside the pituitary gland. Hormonal imbalances can also occur as a result of kidney or liver disease.
Peyronie's Disease Peyronie's disease is a relatively rare inflammatory condition that causes scarring of the erectile tissue in the penis. This scarring produces a curvature in the penis that can interfere with sexual function. In addition, it may cause erections to be painful.
Pelvic Area Surgery Surgery of the colon, prostate, bladder or rectum can damage nerves and blood vessels, which can lead to impotence. Cancer surgery, in particular, often requires removing extra tissue and nerves surrounding the affected area, which increases the chances that impotence will occur. Removal of the prostate or bladder often results in impotence as well. However, despite the cases, newer surgical techniques are now being used to help reduce the rate of impotence by 40 to 60%.
Psychological Causes Although most cases of impotence are a result of physical causes, psychological factors cannot be overlooked. Performance anxiety is among one of the most common psychological causes of impotence. Performance anxiety is the fear that a man will not be able to perform. Other psychological factors that can lead to impotence include stress, depression, guilt, worry, and anger.
