Morning erection is a unique phenomenon for men. The so-called morning erection is strictly defined as erection at night. Normal men have three to five erections at night, usually 15 to 20 minutes each time, and then go down on their own. After a while, they will have erection again, because we don't know about erection at night, but only when we wake up in the morning, So it's called Chenbo. This is a normal physiological phenomenon of men and a sign of male sexual function. If it is a normal morning or night erection, even if the person has impotence, the condition is usually mild, often functional or psychological.
