Erectile Dysfunction Diagnosis Via Blood Test and Clinical Tests

Erectile Dysfunction is a complicated disorder because it can be caused by a number of factors. Before treatment can be provided, your health professional must diagnose the problem and the cause.

Researchers have pinpointed a series of diseases and conditions that are linked to Erectile Dysfunction. These include diabetes, heart problems, high blood pressure, prostate disease, vascular disease and others.

We also have a good understanding of the lifestyle choices that may make some men more vulnerable to developing a Erectile Dysfunction. These lifestyle choices include cigarette smoking; excessive consumption of caffeine and alcohol, substance abuse, stress, eating overly processed foods and lack of exercise.

Other underlying causes of Erectile Dysfunction include injury, trauma incurred during surgery, and psychological factors such as stress, fatigue and depression. However, researchers believe that the majority of these cases can be traced to medically diagnosable conditions.

Medical History

Doctors will start the diagnosis process by asking some questions and by looking through a person’s medical history experts can see if any diseases, physical problems or lifestyle issues may have caused Erectile Dysfunction to occur. Medical history could determine that prescription drugs  or even Over the Counter ones such as NSAIDs are the primary cause of Erectile Dysfunction.

Physical Examination

A medical doctor can carry out a preliminary physical examination that may provide some insight into the cause of Erectile Dysfunction, or enough information to cause the doctor to pursue additional investigation into a specific area.

Lack of normal sensitivity on the penis may be a symptom of problems with the general nervous system.
Abnormal breast enlargement may be the result of a hormonal imbalance such Andropause which may cause low testosterone and serve a secondary issue with a man’s libido.

Decreased pulses in the wrists and ankles which can show a circulatory problem, this may mean blood is not flowing to the penis well enough to gain an erection.

Blood Test

In some patients, the doctor may request a blood test to detect diabetes , high cholesterol , impaired thyroid function. Sometimes he can also request a dose of the testosterone if he thinks that too little male hormone is produced.

Clinical Tests

In order to get at the root of the problem, your physician may order specific clinical tests that require specialized equipment, sometimes elaborate set-up, and a specially trained professional to interpret the results. Here are the four most common clinical tests that your doctor may order.

Duplex Ultrasound

A duplex ultrasound is used to detect a number of medical problems. They are used to find signs of venous leak, atherosclerosis, and to detect any possible scarring of the erectile tissue. A duplex ultrasound is also used to examine blood flow.

Injecting prostaglandin allows a duplex ultrasound to be used for detection of these and other conditions. Prostaglandin is similar to a hormone. Injecting it causes the patient to achieve erection. Once an erection has been achieved, the duplex ultrasound is used to monitor and examine the dilation of blood vessels and to measure the blood pressure in the penis. These measurements are then compared to the penis in its flaccid state.

Nocturnal Penile Tumescence (NPT)

This clinical test uses two specific methods for determining the penis’ circumference and rigidity at night during nocturnal erection. These methods are known as the snap gauge and the strain gauge.

Most men can experience up to five or six erections during sleep, especially during the stage of deep sleep known as rapid eye movement. If the patient is not achieving erections while asleep, this indicates that there may be a problem with the patient’s vascular system and nerve function in the area of the penis.

Penile Biothesiometry

This is a special clinical test that uses electromagnetic vibration. The electromagnetic vibrations are used to evaluate the nerve function in the area of the penis, particularly the area of the shaft and the head. They are also used to evaluate how sensitive the penis is to the vibrations.

If the test reveals that the penis is not responding to the electromagnetic vibrations, this may indicate that there could be possible nerve damage in the area of the penis, thus explaining the patient’s sexual impotence.

Penile Nerves Function Test

Penis nerves function test refers to any kind of test that studies the extent of nerve sensitivity in the area of the penis. One such test is known as the bulbocavernosus reflex test.

In this test, the clinician gently squeezes the head of the penis to see if the anus contracts, a normal response. If it does not, this may also indicate nerve damage to the penis.


An estimated 150 million men suffer from Erectile Dysfunction worldwide at any given time. Erectile Dysfunction affects an estimated 10 million men in the USA alone. That number is much higher when occasional or sporadic bouts of erectile function are taken into account.

The probability of experiencing erectile dysfunction increases with age. Most men who experience Erectile Dysfunction do not seek medical advice or treatment.

The statistics are discouraging only because the causes of impotence can be easily diagnosed, and in the majority of cases, treated successfully.
