Why do men grow up in the morning? Why do men grow up in the morning

4hw.org: many girls will be surprised to see their little brother put his underwear into a tent when they get up in the morning after they have a male ticket. It looks very interesting and funny. Why do men grow up in the morning? There is still a need for those who are suffocated by urine. When does a man start to grow up in the morning? Let's have a look!

The penile erection in men is caused by hemodynamics. The penile consists of two penile sponges and one urethra spongy body. The spongy body is a sponge network structure composed of smooth muscle. The space between the two networks is the cavernous sinus, which is directly connected with the blood vessels. The cavernous body is full of blood vessels and nerve tissue. The most sensitive nerve is the sensory nerve. When men receive external stimulation, such as local contact stimulation, stimulation or mental activity produced by senses such as eyes and ears, etc., can excite the brain nerve center. Under the regulation of cerebral cortex, the erectile nerve center of lumbosacral part sends the erectile nerve impulse, which acts on the blood vessels of penile cavernous body, and obviously dilates the blood flowing into the artery, so it is large * the amount of blood flowing into the sponge body, at the same time, let the blood flow out of the vein constriction, so that the blood flow is reduced, so that the blood is fully retained in the cavernous body rich cavernous sinus, resulting in penile erection.

Normal men's penis, without sexual stimulation and some external stimulation, is usually in a relaxed state. Morning boom refers to the natural erection of the penis in the unconscious state in the early morning, which is generally not controlled by the situation, action and thinking. So why is the morning boom? It is generally believed that there are several reasons:

Chenbo is related to the level of male hormones. After a night's sleep, the level of male hormones such as testosterone reaches its peak at sunrise, which leads to chenbo. It is also believed that this is the result of human evolution. In primitive times, men were also ready to go hunting in the early morning of sunrise. At this time, men had the highest testosterone level and the lowest testosterone concentration at sunset. In this way, nature can ensure that a man has the chance to pass on his genes before going out, so as to prevent him from having no chance to go home because of an accident that day. Therefore, this is also a power that nature endows to a man to carry on his family.

The reflex function of internal organs can also cause penile erection. Perhaps due to the increase of the pressure in the bladder filled with urine in the early morning, it will stimulate internal organs, cause a kind of subconscious reflex erection of penile, and compress the nearby seminal vesicle. Once the stimulation is transmitted by nerve, it will also lead to the phenomenon of ejaculation reaction.

Traditional Chinese medicine holds that "liver is the blood house". When the human body is sleeping, the blood volume of the liver is several times that of normal times. We know that the penile cavernous body is actually a vascular organ tissue, which can also bear the responsibility of "blood bank storage" for the liver. In this case, of course, it will expand because of unconsciously congestion.

In the process of deep sleep, the penis will also have an erection, which usually occurs in the intermittent period of rapid eye movement, that is, the stage of dreaming. At this time, penis erections are usually not disturbed by psychological factors, which can more realistically show the functional status of men's surnames. Generally speaking, men's surnames have erections three to five times every night, with an average of 15 minutes each time, but also for up to an hour. As long as the structure and function of nerves, blood vessels and penile cavernous body are normal, there will be erections. So it's a very normal phenomenon for a man to have an erection at night. He doesn't need to worry about it, and the erection at night can restore the energy of the penis. The repeated erection will send more fresh, nutritious and oxygen rich blood into the penis, just like charging.

The male's morning budding is also a normal physiological phenomenon. When he is 20-30 years old, the number of erections increases in the early morning, and then decreases in the middle age. During the period of disease, the phenomenon of penile erection will disappear in the morning; when the body recovers, the phenomenon of penile erection will appear again. Sometimes due to poor energy or state, chenbo is not obvious, but it is not harmful to health. Chenbo phenomenon does not appear every day, but in a long period of time, it is a problem. Therefore, the early morning erection of penis can be used as one of the reference indicators to observe the energy and health status of men.
