Male sclerosis generally refers to penile sclerosis, which is currently diagnosed through physical examination, ultrasonography, cavernography and MRI. 1. Physical examination: The doctor will observe the changes in the appearance of the penis with the naked eye and determine the presence of hard nodules and plaques by touching them with the hand. 2. Ultrasonography: It can further evaluate the size and location of the nodules and plaques, and also assist the doctor in understanding the function of the blood vessels in the penis. 3. Cavernography: When patients with penile sclerosis undergo this examination, it can show the changes in the structure of the white membrane as well as the fibrous nodules. 4. MRI examination: the examination can be carried out respectively when the patient is erect and in the state of weakness, which can further reveal the hardness that ultrasound fails to find.
