Boys in the erection, the following dick is going to be some changes, but many people are not clear about their own erection when there is what it looks like, because each man's sexual organs are different, in the erection, the state is naturally different, then, what kind of men erection? What does it look like when a man is hard? Below, and we come together to understand the knowledge of men's erection.

Maintaining erectile function three major elements

1, appropriate stimulation

2, normal nerve function

3, adequate blood supply

Men usually have 4 kinds of erection state

The man's genitals erectile They all look the same, but the principles are different. Psychological activities, mechanical stimulation and the lifting of brain inhibition may all lead to an erection. As a result of scientific research, there are usually 4 states of erection in men's genitals and they are associated with sexual health.

①. Psychological erection

When a man is excited by the stimulation of the cerebral cortex due to auditory, visual, olfactory as well as thinking and imagining about sexual content, and transmitted through the thoracolumbar erection center of the spinal cord, and then acted on the ding dong spongy body, it will make the arterial vasculature dilation, a large amount of blood flow into the ding dong spongy body; venous vasculature constriction, when the blood flow out of the spongy body is reduced, the blood will be fully retained. In the rich blood vessels and blood sinuses in the corpus cavernosum, so that the ding dong quickly produce psychological erection. Conversely, when arterial vasoconstriction reduces the flow of blood into the corpus cavernosum; venous vasodilatation allows the rich blood flow trapped in the corpus cavernosum to return rapidly, and the penis returns to weakness.

②. Reflex erection

And the external genitalia by direct touch, walking friction and other local stimulation or receive from the internal stimulation of the rectum and bladder, etc. can cause reflex erection, this is through the stimulation of the spinal cord in the sacral medulla of the lower erection center after provoking its sexual arousal to achieve.

Ding-dong erections are innate, and male fetuses can become erect in the womb. A young boy may also have an erection that hardens when he urinates after birth, and sometimes lying down to urinate can cause the urine to spray like a spring straight into the adult's face, often bringing unexpected laughter and joy to the parent who is changing the diaper, but the erection at this time does not have any sexual connotation.

Any stimulation of the genitals themselves can cause reflex erections, which are regulated through the nerves of the female private parts and the sacral medullary erection center. These two psychological and physiological stimuli can either act alone or influence each other and **** involved in sexual activity.

For example, when a spinal cord injury occurs above the thoracolumbar region, the patient can only have an erection if the genitals receive physical stimulation, and the ability to have a psychological erection disappears. When motor neuron injury occurs at a level below the thoracolumbar region, stimulation of the genitals fails to elicit an erection, whereas 24-57% of patients still experience a psychogenic erection, meaning that psychogenic stimulation can be delivered via the thoracolumbar pathway. When spinal cord injury occurs at lumbar 2 to sacral 1, both psychological and reflexive erections are present, but the two cannot be harmonized, and ejaculatory orgasm is not possible through genital stimulation.

③. Night erection

Normal men in addition to psychological erection and reflex erection, there is a night erection, men's sleep is always in the rapid eye movement sleep period and slow eye movement sleep period in the alternation, but also experienced an erection - - weak - - and then erection - - and then weak physiological process, which is known as the medical ding ding night erection, is a normal physiological process in the health of men. Generally speaking, men will have 4 to 6 times a night, each 20 to 40 minutes of erection, the total **** erection up to two and a half hours. This is because the brain in the daytime always have to inhibit the occurrence of sexual reaction, otherwise it is inevitable that men from time to time to encounter embarrassing situations, but to sleep, the brain of this inhibition disappears, ding ding will be spontaneous erection reaction, this is completely normal, do not have to worry about.

The duration, frequency, and hardness of nocturnal erections decrease with age, and are strongest from puberty to about age 20. Whether it's a psychological or reflex erection, the ding dong quickly returns to normal after external stimuli are lifted. Nocturnal erections are no exception. After an erection for a period of time, the ding ding will definitely weaken on its own because if the blood is allowed to remain in the corpus cavernosum for a long period of time, the blood will be deprived of oxygen and accumulate a large amount of metabolic wastes, which is detrimental to the tissues, and in severe cases, necrosis can occur.

There is a ding ding abnormal erection of the disease is this, the patient manifested ding ding more than 4 to 6 hours of persistent swelling, hard, painful, greenish gray color, this is a urological emergency, need to go to the hospital as soon as possible emergency treatment. So ding ding is not all night erection, but necessarily have tension and relaxation.

④. Early morning erection

Early morning erection is a clinically significant physiological phenomenon. Some doctors have studied this phenomenon and found that during a man's illness, the early morning erection will be weakened or disappeared; and after the body recovers, the early morning erection will also be restored. Therefore, the phenomenon of early morning erection can be used as a reference indicator of men's health. The presence or absence of an erection in the morning can also be used as a reference indicator for determining the state of a man's sexual function.
