Causes of impotence, four factors you must guard against

1. Organic diseases

(1) Vascular causes include any disease that may lead to decreased blood flow in the corpus cavernosum arteries, such as atherosclerosis, arterial injury, arterial stenosis, pudendal artery shunt, and cardiac dysfunction, or penile venous leakage caused by obstruction of venous reflux, closure mechanism of the tunica albuginea of ​​the penis, or decreased smooth muscle in the sinus cavernosum of the penis.

(2) Neurogenic central or peripheral nerve disease or damage can lead to impotence.

(3) Surgery and trauma: Major vascular surgery, radical prostatectomy, radical abdominal, perineal, and rectal cancer resection, pelvic fracture, lumbar compression fracture, or straddle injury can cause damage to the blood vessels and nerves related to penile erection, leading to impotence.

(4) Endocrine diseases Impotence is often caused by endocrine diseases, mainly diabetes, hypothalamic-pituitary abnormalities and primary gonadal insufficiency. According to foreign reports, 23% to 60% of male diabetic patients suffer from varying degrees of impotence. Its occurrence mechanism is mainly related to autonomic neurofibropathies on the corpus cavernosum of the penis, stenosis of penile blood vessels, endocrine abnormalities and mental factors.

2. Diseases of the penis itself

Such as penile induration, penile curvature deformity, severe phimosis and balanitis.

3. Urogenital malformations

Congenital penile curvature, double penis, small penis, penoscrotal displacement, retroversion of bladder, urethral fissure, congenital absence or dysplasia of testicles, scar formation of corpus cavernosum fibers, varicocele, etc., which lead to inability to achieve erection.

4. Urogenital diseases

It is common for impotence to occur secondary to chronic inflammation of the urogenital system, such as orchitis, epididymitis, urethritis, cystitis, and prostatitis. Among them, chronic prostatitis is the most common cause of impotence. Urogenital system surgery and certain injuries, such as prostatic hyperplasia, prostatectomy, urethral fissure, penile and testicular injuries, can all cause impotence. Chronic renal failure patients often suffer from impotence due to testicular atrophy and decreased testosterone.
