What about insufficient blood supply to the penis?

In general, it is difficult to judge whether the penis is not supplied with blood by hand. Generally, it is through ultrasound examination that the speed and peak value of blood flow in the dorsal artery of the penis are determined to determine whether the blood supply to the dorsal artery of the penis is sufficient. If the penile ultrasound examination finds that the blood supply to the dorsal artery of the penis is insufficient, it is generally possible to increase the blood flow to the penis by using drugs that expand blood vessels. The more commonly used drugs are sildenafil, tadalafil, vardenafil, etc. Penis blood supply deficiency needs to actively look for what causes blood supply deficiency. Common diseases are peripheral vascular disease caused by diabetes, hypertension, hyperlipidemia and other causes of peripheral vascular disease.
