Is erectile dysfunction impotence?

Sometimes the penis will suddenly appear persistent erection, which will thicken and harden, accompanied by pain at the root of the penis, but the glans penis is not painful. Erection time can be hours, days or weeks, sometimes ejaculation occurs, but after ejaculation still has an erection. If not treated in time, it will cause cavernous fibrosis, permanent impotence and necrosis of penis parts. Traditional Chinese medicine calls "abnormal erection of penis" "strong yang" or "strong middle". The causes of priapism can be divided into primary and secondary, primary priapism.

The cause of erection is not clear; There are several reasons for secondary penis abnormality:

A neuropathy: caused by spinal nerves or neuropathy distributed around genitals, such as spinal cord injury and neurocytokinin.

B. Mechanical: late pelvic tumor, infiltration and compression, external force (such as metal ring) continuously pressing the root of penis, local trauma of penis, etc.

C. Hematological diseases: leukemia, polycythemia vera, sickle cell anemia, thrombophlebitis, glucose phosphate isomerase deficiency, etc.
