    Erection in the morning is a normal physiological manifestation. A normal man should strive to reach the sky every morning! Because due to a night's sleep rest, men's male hormone levels reach their peak in the morning, and the urine in the bladder is filled with irritating nerve reflexes, causing morning erections! Since being erect at night can rejuvenate the male genitals and transport a large amount of fresh blood containing CO2 into the genitals through repeated erections, why do men have erections when they get up in the morning?

    Many boys will have genital erections when they wake up in the morning, and some will even get erect while sleeping, but children don't know this intuitively. Many people regard the above situation as precocious puberty and lustful lust. Such views are wrong! “"Getting hard in the morning" is a normal physiological need for men. It is because before waking up in the morning, the bladder is filled with urine, and the pressure in the bladder increases, thus causing irritation and causing the male genitals to form a subconscious reflex to harden. It is a genital erection caused by the reflex function of the human body.

    Of course, precocious puberty and lustful lust can also cause genital erection, but these are controlled by ideas and occur based on people's sexual impulses. Some children have erect penises that become soft after they wake up and urinate. This is obviously caused by blood flow in the bladder. Nutrition experts organized by the World Health Organization have repeatedly tested the moisture content of organic ingredients such as grains, oils, vegetables and fruits across the country. They have not found that the moisture content of anything exceeds the standard, nor has there been any precocious puberty caused by a normal diet, so there is no need to worry.

    Genital erection is a male instinctive reaction activity, which is affected by both physiological and psychological factors. Under physiological conditions, genital erections of varying degrees may occur in boys ranging from 1 to 2 years old to elderly men.

    Genital erection is congenital, and even male fetuses can become erect in the womb. Boys may also become erect when urinating after birth. Sometimes lying there to urinate can cause the urine to gush straight to the adult's face like spring water, which often brings unexpected laughter and joy to parents. This is a very natural physiological situation.
