What tests should be done for male sexual dysfunction?

Male sexual dysfunction is a very serious disease. After suffering from male sexual dysfunction, you must pay attention to check and receive timely treatment. Once a male friend has sexual dysfunction, it will cause great harm to his health and will also affect his self-esteem. What kind of examination should be done for male sexual dysfunction? The following will give some help to many male friends and a brief introduction.

Liver and kidney function, blood sugar, blood lipid tests and hormone level measurements can help explore the causes of erectile dysfunction.

1. Nighttime penis swelling test

NoctuRNAl penile tumescence (NPT) is one of the important and objective indicators for distinguishing psychological from organic erectile dysfunction. In a normal male's 8-hour sleep state, the penis can have 3 to 5 erections, lasting 15 to 25 minutes per time, and the hardness of the erection should reach 65%. With age, the strength and duration of the erection will decrease slightly. If the 8-hour test is abnormal, it is considered to be caused by organic factors, and usually needs to be repeated 2 to 3 times.

2. Injection of vasoactive drugs into the corpus cavernosum of the penis

Vasoactive drugs include poppyrine, phentolamine and prostaglandin E1, which can be used alone, in combination of two or three drugs. Normal erection occurs 5 to 10 minutes after drug injection and can be maintained for more than 20 minutes under sexual stimulation, indicating that the blood circulation function of the penis is still good. Late erection, early erection disappearance or no rigid erection may indicate obstruction of penile arterial blood supply or inability to block venous blood flow.

3. Penile vascular system testing

The use of Doppler ultrasound blood flow color imaging technology can accurately observe the changes in the diameter of the penile artery, maximum blood flow, and resistance index of the penile corpus cavernosum before and after the injection of vasoactive drugs. It can directly identify whether there is arterial or venous erectile dysfunction. Before surgical treatment is required for suspected arterial lesions or venous reflux lesions, internal pudendal artery angiography should be performed to observe the dynamic perfusion test and angiography of the penile arteries or penile corpus cavernosum on both sides, which will help diagnose the obstruction of penile venous reflux.

4. Testing of the erectile nervous system

By measuring the intravesical pressure, electromyography, bulbocavernosus and sciatic cavernous muscle reflex latency and somatic sensory evoked potential, the functional status of the autonomic and somatic nerves that control penile erection is evaluated to identify whether erectile dysfunction is caused by nervous system lesions.

5. Penile corpus cavernosum puncture biopsy

Patients with erectile dysfunction often have abnormalities in the structure of the corpus cavernosum of the penis and reduced smooth muscle volume. Even if arterial blood supply and venous reflux are corrected surgically, the treatment effect is not ideal. Meuleman's study found that the smooth muscle volume of the corpus cavernosum of the penis at the age of 30 is 65%, while it is only 48% at the age of 80. If the smooth muscle volume of the corpus cavernosum in the biopsy is only less than 30%, any arterial or venous surgery will not be effective.

Once a male friend develops sexual dysfunction, he needs to consider the necessary examination methods. In fact, necessary examinations are more important. What examinations should be done for male sexual dysfunction? The above examination items need to be done. Only in this way can the condition be alleviated and serious harm be prevented. In fact, it is necessary to do a good job of examination when facing male sexual dysfunction.
