Men should know that sometimes they joke that they like to use the word impotence. Impotence is a kind of erectile dysfunction of sexual function, which mainly refers to sexual desire, erection or weak erection. So, what is the cause of impotence? Let's see how experts introduce it.
1、 Organic disease
(1) Vascular causes: including any disease that may lead to the decrease of blood flow in the cavernous artery of the penis, such as atherosclerosis, arterial injury, arterial stenosis, penile artery shunt and cardiac dysfunction, or the penile white membrane obstructing the venous return and closure mechanism, and the reduction of smooth muscle in the cavernous sinus of the penis.
(2) Nervous causes: diseases or injuries of central and peripheral nervous systems can cause impotence.
(3) Operation and trauma: Vascular surgery, radical resection of prostate cancer, radical resection of abdomen, perineum, rectal cancer, pelvic fracture, lumbar compression fracture or riding injury can cause vascular and nerve injury related to penis erection, leading to impotence.

According to foreign reports, 23%~60% of male patients with diabetes have different degrees of secondary impotence. Its pathogenesis is mainly related to autonomic neuropathy, penile vascular stenosis, endocrine abnormalities and mental factors.
2、 Diseases of the penis itself
Such as penis induration, penis bending deformity, severe phimosis and prepuce balanitis.
3、 Urogenital malformation
Congenital curvature of penis, double penis, small penis, displacement of penis and scrotum, retroversion of bladder, urethra, congenital testicular defect or dysplasia, formation of scar of penis sponge fiber, varicocele, etc.
4、 Urogenital disease

Prostatic hyperplasia, prostatectomy, urethral rupture, penis, testicular injury and other urogenital surgery and some injuries can cause impotence.
