Usually, morning erection can be used as a reference for normal and strong performance of sexual function, but it is not absolute and may be affected by physiology or drugs.
Morning erection refers to the natural erection of the male penis in an unconscious state from four to seven o’clock in the morning, not controlled by thoughts, situations or actions. Generally, when men enter puberty or adulthood, they will experience morning erections, which will become more frequent and last longer as they grow older. After the age of 30, this phenomenon will gradually weaken or decline.
When the bladder stores too much urine, stimulated by pressure, it may also cause a reflex erection to occur in the penis. Some proprietary Chinese medicines contain drugs such as ginseng, wolfberry and deer whip, which can also cause morning erections.
Morning erection is generally a normal physiological phenomenon, do not worry too much. However, when patients experience serious or persistent physical discomfort, they should go to a professional hospital in time.
