Erectile Dysfunction and its Diagnosis

The inability to develop or even maintain erection during sexual act is known as erectile dysfunction or ED. The penile erection in men occurs because of hydraulic effect. The blood enters the area which is made up of sponge like bodies to cause the penis to become erect. Sexual arousal cause signals to get transferred to different parts of the body from the brain to nerves within penis. If at any point this signal is affected, the entire process falls apart.

Various systems are conjoined together in the procedure. The circulatory system is somewhat responsible. At the same time voltage-gated channel of potassium is also responsible. Hence, those who have diabetes or cardiovascular diseases are often noticed to experience erectile dysfunction. Psychological problems or neurological issues as well as hormonal insufficiencies result in erectile dysfunction as well.

While physiological causes are mostly in lines of hormone, circulation and transmission in between nerves of the body, the psychological causes are because of failure in feelings or thoughts. Erectile dysfunction can be treated by means of PDE5 inhibitor, such as Levitra. There are available for treatment prostaglandin tablets, injections, penile prosthesis, penis pump, etc.


There are no formal tests to correctly diagnose the erectile dysfunction. Nonetheless some blood tests are done to exclude other underlying diseases like prolactinoma and hypogonadism. Since, diabetes is also one of the reasons to why erectile dysfunction occurs, so blood sugar tests are performed.

Erectile dysfunction is also associated with obesity, poor health, dietary habit, cardiovascular diseases, etc. sometimes coronary diseases of the artery and peripheral diseases of the vascular system is also responsible. It is essential to exclude these reasons with proper blood tests.

The patients are first asked whether or not they even had erection. If the person never had erection, then the chances are that the problem is physiological. Rarely, it is psychological.

Physicians recommend duplex ultrasound test to diagnose the problem. With this test, one can evaluate the conditions of any venous leak as well as analyze blood flow. This test can also diagnose whether of not there are any symptoms of atherosclerosis or calcification or scarring within the erectile tissue. In this test a stimulator is induced in the body which is like a hormone, called prostaglandin. This stimulator induces erection. After introduction of the stimulator, ultrasound is used to detect blood pressure in penis as well as vascular dilation within the penis.

Bulbocavernosus reflex test is also used to detect issues in the sensation of the nerve of the penis. In this test the head of the gland of the penis is squeezed which causes the anus to squeeze.

Penile rigidity is measures through two methods. One is snap gauge and another is strain gauge. Other than that penile biothesiometry is also studied by use of electromagnetic vibration to analyze the nerve functions of the glands and the sensitivity of the shaft of penis. Three other tests are dynamic infusion cavernosometry, where fluid is pumped to measure the vascular pressure, corpus cavernosometry, where saline is induced to measure the corpus cavernosum pressure and another procedure is magnetic resonance angiography.

For treatment you can use Levitra for erectile dysfunction
