What are the reasons for penis erection?

Penile erection failure is also known as impotence. It is a male sexual dysfunction that can cause disharmony in couples' life and undermine men's self-confidence and dignity. Many men are reluctant to see a doctor because of their inability to have an erection. So what causes their penis erection failure? Let's talk about it in detail below.

Causes of erectile dysfunction:

1. Psychological ED refers to erectile dysfunction caused by psychological factors such as tension, stress, depression, anxiety and marital discord.

2. Organic ED

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

(2) Neurological causes: Central or peripheral nerve disease or damage can lead to erectile dysfunction.

(3) Surgery and trauma: Surgery such as major vascular surgery, radical prostatectomy, radical abdominoperineal rectal cancer surgery, and pelvic fractures, lumbar compression fractures, or straddle injuries can cause damage to the blood vessels and nerves related to penile erection, leading to erectile dysfunction.

(4) Endocrine diseases, chronic diseases and long-term use of certain medications can also cause erectile dysfunction.

(5) Diseases of the penis itself: such as induration of penis, penile curvature, severe phimosis and phimosis.

3. Mixed ED refers to erectile dysfunction caused by both psychological factors and organic causes. In addition, since organic ED is not treated in time, the psychological pressure of patients increases and they are afraid of sexual intercourse failure, making ED treatment more complicated. A study on the etiology classification of a group of 628 ED patients in China showed that psychological factors accounted for 39%, organic factors accounted for 15.8%, and mixed factors accounted for 45.2%.

The above are the main reasons for penis erection failure. Penile erection failure will affect family harmony. Therefore, when such a problem occurs, you must go to the hospital for treatment in time to find out the cause of the disease. Only in this way can you prescribe the right medicine and restore a healthy married life.
