To diagnose an erectile dysfunction, usually a check up is not enough. There are various tests needed to be done to successfully reveal the root cause of the disorder. The following are as follows:
Blood Hormone Studies
Prolactin levels and testosterone are measured to check if there are abnormalities in either of these two sex hormones.
Complete Blood Count (CBC)
This set of blood tests can detect anemia. Anemia indirectly causes erectile dysfunction as this condition is caused by fatigue, a byproduct of anemia.
Nocturnal Penile Tumescence (NPT)
This kind of test aims to see and measure a man’s erectile functions while asleep. Lack of erections while you are sleeping spells a problem with circulation or nerve function disorders. This test makes use of two methods. The first one which is the snap gauge method is done by wrapping three plastic bands with different strengths around the penis. The erectile function will be measured based on which of the three bands breaks.
On the other hand, the second method is the strain gauge method. It is performed by placing elastic bands around the base and the tip of the penis. The erectile function is measured in the change in penile circumference if ever an erection occurred during that night.
This kind of test takes note of the nerve sensation building around the penis. During the test, there should be an immediate reaction from your rectum as the head of your penis is squeezed. If there is delayed or no reaction at all, then it is an indication of an abnormal nerve function.
Erectile dysfunction can also be diagnosed through urinalysis. Submitting a sample of your urine to the laboratory will enable them to get information on the level of sugar, protein and testosterone. These substances are indicators of diabetes, testosterone deficiency and kidney disease – all that can cause erectile dysfunction.
This kind of test may be considered as the best test to evaluate erectile dysfunction. The ultrasound is used to evaluate blood flow and check for the signs of tissue scarring, venous leak or artherosclerosis. This is performed both while the penis is erect, aided by an injection of a erectile stimulating drug, and when it is soft.
This kind of test uses electromagnetic vibration that aims to determine nerve function and sensitivity. Nerve damage can be detected if there are manifestations of decreased sensitivity to vibrations.
