In the reproductive and male clinics, erectile dysfunction patients are more, because this represents the male characteristics of erectile dysfunction, making many men “loss of face”, very hurt self-esteem, then, the penis erection why there is a “failure”? The key time why the penis will not obey orders, “arbitrary strike”? In fact, the penis “strike” is also a reason. Today, we will talk about the penis, an important organ of the “joy and sorrow”, only to clarify this point, in order to effectively understand the mystery of this vital organ, but also for the treatment of erectile dysfunction, that is, ED to lay a good foundation. First of all, we say that all human functions are the result of natural selection. Erectile function is no exception. For men, to complete the function of fertility, the erection of the penis is a necessary condition, only then, the male sperm can be sent into the female reproductive tract to complete fertilization. Therefore, this function of the male penis erection is very amazing and is one of the most important and representative functions of the male, known in medical terminology as “erection”. How does an erection happen? In fact, the mechanism of erection is very complicated, not that medical people are not aware of it, and to be honest, the current medical progress is not completely clear. Due to the lack of knowledge, there have been many misconceptions about the function of erection for a long time. For example, there is a little joke. The teacher asked a female student who was not listening carefully to the lecture: what organ will be 10 times larger when it is inflated? The female student immediately blushed and lowered her head, and everyone probably guessed the answer she was too ashamed to answer. And the correct answer to this question is: the pupil. In fact, the penis has its own expansion factor when it is erect. A penis that is normally larger may increase in size by less than a factor of one when erect. However, a penis that is normally small may increase in size by a large percentage when it expands, due to its large expansion coefficient. Almost most penises are not very different in the erect state. We say that structure determines function. So, how does the penis perform its primary function of erection? In addition to the urethra, the penis has two cavernous bodies, and under normal circumstances, an erection occurs when the cavernous bodies are filled with blood. Of course this happens under normal innervation. When the body is sexually stimulated by hearing, seeing, touching, etc., the nerve impulse is transmitted to the brain center, and the brain command gives instructions, under the instruction of this command, the blood inside the spongy body starts to enter, while the blood flowing back to the heart from the spongy body decreases, and more enters and less flows out, so the penis naturally becomes hard, which is also called “erection This is also known as an “erection”. In normal males, this erection is controlled by a switch and can occur at any time at the touch of a button. Especially after puberty, if the sexual stimulation, the penis may be erected at any time to mess up. This is one of the signs of normal development in adolescent boys. As just mentioned, this erectile function depends on normal structures: the corpus cavernosum and innervation. Some patients with organic lesions who have not had an erection since puberty are pathological and should go to the hospital to find out the cause. Some may ask, since there is blood entering the corpus cavernosum, the blood can flow back out through the veins, huh? And when the penis is erect the veins return less blood out, why is this? Under normal circumstances, the structure of the penis has a thick fibrous membrane – the white membrane – that compresses the corpus cavernosum, causing the venous return to be blocked. If a vein “leak” occurs, most of the blood that enters the corpus cavernosum flows back out, so the penis cannot maintain an erection, which is also a pathology that often leads to erectile dysfunction, called “venous leak”. Just now, we have given you a brief introduction to the structural basis of the penis erection, below, let’s experience the “joy and sorrow” of the penis. The penis, like our body, also has “happy, sad and happy” expressions. Why is the penis happy and sad? The reason is simple. Because the human body is a very sophisticated system, the brain is the command, the penis is part of the body, there is blood flow, innervation, under the command of the brain command, will naturally show their emotional cycle changes. Understanding the joy and sadness of the penis is the same as understanding the laws and characteristics of the normal male sexual response cycle. Therefore, we must do to comply with the law, sexual life can not be forced to do, in order to benefit the health. l, happy The old saying: hear over is happy. This is one of the virtues of human beings. But the penis does not have such a good virtue. The penis is the smell of “color” is happy. When the body receives pornography (including auditory, visual, tactile), the penis will react with an erection. This indicates that the penis likes these stimuli very much. Of course, the premise is that the penis has good nerves and blood vessels and other structures. 2, anger Anger, the most typical anger is described as “angry hair”. This is somewhat similar to the “penis anger”. Under continuous stimulation, the penis maintains an erect posture, the veins can be seen on the surface of the skin, the erection angle is close to vertical with the body (abdominal wall), the penis becomes hard and shows regular fluttering with the inflow of blood from the blood vessels, and due to the rich blood flow to the penis head, it can show congestion and swelling, which is what we call the fourth degree of erection, and is a necessary condition for intercourse. Logically, the penis “rage” is a sufficient condition for sexual intercourse. That is to say, only the erection of the penis can have the prerequisite for sex, and at the same time, if a successful sex life occurs, there is bound to be an erection of the penis. 3, joy, refers to the penis in the accumulation of sexual stimulation to a certain degree, in the brain center under the domination of the involuntary ejaculation of the orgasm. This feeling cannot be suppressed and is accompanied by a sense of pleasure, a sense of euphoria. As of today, we have not completely figured out the specific regulatory mechanism of ejaculation, but most studies believe that ejaculation is related to the release of various neurotransmitters from the central nervous system, involuntary contraction of the pelvic and urethral muscles, and other factors. 4, mourning Finally, we talk about the “mourning” of the penis. The “mourning” of the penis refers to the “indifference” to all stimuli for a certain period of time after the male penis has become erect, leading to ejaculation climax, which is medically called the “inactive period”. This is an important point in male physiology. This is a very important point in male physiology and is a self-protective response of the human organism. This is very different from women. Women can respond to a second sexual stimulus after orgasm, i.e., they can have several consecutive orgasms, whereas men cannot. The length of the erectile withdrawal period varies from person to person and from age to age. In young people, this period of inactivity may be a few minutes, for older people it may be long, even several hours. In contrast to the male erection, the female sexual initiation is very slow, but, once initiated, the female ability to perform is unmatched by the male, which is precisely the fault of the male expiration date. It is often said that men are “hotter” and women are like “electric irons”, and herein lies the truth. The penis is a very good choice for the purpose of the “happy and sad”, we should follow the law. That is, at some point, sex can not be forced, do not force. Another situation, some men are influenced by the traditional concept that “a drop of sperm, ten drops of blood”, and conscious sperm not ejaculate, in the near climax of the time and choose to suspend sex, such behavior is also bad, it makes the sexual impulse is not easy to vent, making the pelvic organs of congestion is not easy to subside, over time, may lead to disease. In other words, do not violate the objective law of penis joy and sorrow mentioned above. Both foul play and derangement are certainly harmful to life and health, and listening to the likes and dislikes of this important organ of the penis lays the foundation for our treatment of the disease of penile slackness.
