Why do men have morning erections? Male morning erection is a normal physiological phenomenon

When the sun rises in the morning, the male penis also stands up, and the women who sleep around feel pierced by their body. Many women often complain that they wake up without an alarm clock every morning. Why do men have erections in the morning? The occurrence of this phenomenon has certain physiological basis.

Male penile erection is caused by hemodynamic reasons. The penis is composed of two penile cavernous bodies and one urethral cavernous body. The cavernous network is composed of smooth muscle of the cavernous body. The space between the networks is the cavernous sinus, which is directly connected with the blood vessels. The cavernous body is full of blood vessels and nerve tissue, and the most sensitive nerve is the sensory nerve. When men receive external stimuli, such as local contact stimuli, sensory stimuli such as eyes and ears, and psychological activities generated by consciousness, make the brain nerve center excited. Under the regulation of the cerebral cortex, the erectile nerve center in the lumbosacral region produces erectile nerve impulses, which act on the vessels of the cavernous body of the penis, significantly expanding the arterial vessels into which blood flows, and a large amount of blood flows into the penis of normal men in the cavernous body, In the absence of sexual stimulation and some external stimulation, it is usually in a relaxed state. Morning erection refers to a man's penis erecting naturally in an unconscious state in the morning, which is generally not controlled by the situation, action and thinking.

Why do you have an erection in the morning?

Morning erection is related to the level of male hormones. After a night's sleep and rest, the level of male hormones, such as testosterone, reaches its peak at sunrise, so morning erection is considered as the reason. Some people believe that this is the result of human evolution. Men in primitive times also stopped hunting at sunrise in the morning. At this time, the testosterone level of men was the highest, and the testosterone concentration was the lowest at sunset. Naturally, men have the opportunity to communicate their genes before going out, and they have no chance to go home because of the accident that day, which is also the power of nature to convey to men.

The reflex action of visceral organs will also lead to penis erection. In the morning, the pressure in the bladder filled with urine will increase, stimulating visceral organs. The reflex erection of the penis subconsciously will compress the nearby seminal vesicles. This stimulation will also cause ejaculation reaction through nerve transmission.

Traditional Chinese medicine believes that tubular organs and tissues can take part of the responsibility of storing blood in the blood bank for the liver. In this case, of course, they will expand due to unconsciously hyperemia.
