1、 Penis size:
In the statistics of penis size, according to the different statisticians, there are the following groups of data: 1. Jiang Yu et al. measured the static penis length of 470 teenagers, and found that the penis length of those over 17 years old was 7.0-9.8cm. 2. Zhu Huibin et al. measured the static penis length of 900 men aged 25-35 years old. The length was 6.9 (plus or minus 1.4 cm) and the diameter was 2.5 (plus or minus 0.4 cm). The length of the penis was 11.6 (plus or minus 1.7 cm) and the diameter was 3.3 (plus or minus 0.4 cm) under the condition of negative pressure passive erection. 3. Zhang Sixiao et al. investigated the penis length of 2029 adult men in China, with an average of 7.21 (plus or minus 2.59cm).
There is no uniform standard for the definition of penis in China. In the past, it was considered that the static penis length measurement<4cm was a small penis. Now, based on the penis draft length, it is considered that the reference value of small penis is:<2.5cm for newborns and<5.5cm for adults.
Attachment: Static penis length - measure the length of the penis under weakness, which is the distance from the pubic symphysis (the bone structure that can be touched in the middle of the lower abdomen) to the external opening of the urethra.
Penis draft length - hold the crown groove of the penis head with your thumb and index finger, stretch the penis to make it fully extended, and then measure it with the static length measurement method.
As for the length of penis after erection, there are few such data in China. Because in the traditional medical concept, doctors are more concerned about whether the sexual organs are mature and fertile. There are not enough data on "minor" penis erection length. It is generally believed that penis erection is normal at 10-19 cm. I hope we can see more authoritative data in the future.
2、 Mechanism of penile erection:
Why does the usually so weak penis become hard and powerful due to erection?I believe that this has confused many friends.
This starts with the anatomical structure of the penis. The most important structure of the penis is two penile cavernous bodies and one urethral cavernous body. The spongy body is like its name, and its structure is like a sponge. It is composed of vascular sinuses. At ordinary times, the blood flow through it is very small, only about 4ml per minute, and the entire penis is in a weak state. When sexual excitement occurs, during the stage of inducing penile erection, the blood flow can suddenly increase to 80-120ml per minute, with an average of 100ml. Even after full erection, 20-40ml blood flow per minute is still required to enter the penis sponge in order to maintain this erectile state and stiffness. Under the effect of this increased blood flow, the pressure in this "sponge" suddenly increases, and the penis becomes erect and hard.
This is the same as inflating the tire. When the tire is fully inflated, the tire becomes hard, which should be easy to understand. Of course, the mechanism of penile erection is much more complicated than this. It is a dynamic balance. There is constant congestion and blood return, so as to always maintain a certain pressure in the cavernous body of the penis, so as to maintain the erection and erection hardness.
It is not difficult to see that the main factor determining the size and hardness of the penis after erection is the blood flow to the penis.
3、 "Penis worship" complex:
No matter how many doctors and sex knowledge promotion websites are bothering to tell people that it is impossible for an adult penis to grow again, and the more important factors determining the harmony of life are the feelings of both sides and the skills of sexual life. But few people can really listen to such kind advice. One of the simple facts is that if you have a strong "equipment", it will not only enable men to have a great sense of pride, but also more easily bring women a satisfying sexual life experience.
This "phallic worship" complex of males comes from birth, which can be based on the ancient "genital worship" era. Among all species in the world, the proportion of human genitalia and body weight is the largest among all animals. Not only that, human development today, the body, especially the function of the sports system has been seriously degraded. The only exception is that men's genitals are growing. Therefore, some religious groups believe that today's human beings are living in the era of "excessive immorality" and "excessive sexual desire".
4、 Ways to increase penis:
Now, there are many magic drugs that claim to make the penis "grow" again in the "garbage ads" that are crammed into my house every day. These people should go to win the Nobel Prize!Because when I was in school, I knew that it was impossible to "grow" again when a person's sexual organs were mature, which is a scientific conclusion. Since this conclusion has been overturned, they are certainly entitled to the Nobel Prize, which is also the "pride" of our Chinese people!
So, it is impossible to enlarge the penis?No, as long as you are willing to work hard, you can increase your penis. This is a physiological increase.
What is "physiological enlargement"?For example, a thin and weak person can have strong muscles as long as he is willing to work hard to exercise. This does not mean that his muscles have "re developed" and muscle fibers have "increased" after exercise. But after exercise, each of his original muscle fibers became strong and thickened. In this way, his overall muscle appearance becomes strong. This is a physiological increase.
Similarly, after a man matures, the penis cannot develop again, which increases the number of vascular sinuses in the penis sponge!However, as long as you are willing to make efforts, you can increase the congestion of each sinus, and the elastic fibers in the sinus can stretch to a certain extent. When each of your vascular sinuses is enlarged due to sufficient congestion, your penis will grow and thicken as a whole. Of course, this growth has some physiological limits.
How to increase the congestion of vascular sinus?As we have said above, the main factor determining the size and hardness of the penis after erection is the amount of blood flow to the penis. Therefore, the key to increasing the penis is to increase the blood flow to the penis during erection.
First of all, you must have a normal sexual system, sexual organ function. The balance of hypothalamus pituitary gonad axis is the most important factor to regulate the normal function of human sexual system and organs. When the function of hypothalamus pituitary gonad axis is disordered and unbalanced, people are prone to sexual dysfunction. At this point, talking about penis enlargement is just empty talk. If your sexual ability is not very good, please first treat and adjust your sexual system and organs to return to normal.
Secondly, do targeted exercises to enhance the ability of the body to flow blood to the penis. There are many such methods, including systemic factors and local factors:
1. Systemic factors:
a: Exercise can improve physical fitness and improve the blood circulation of the whole body. No one doubts that sports can improve physical fitness, but what kind of sports is the most ideal?I highly admire aerobic exercise, which is popular all over the world. The greatest advantage of aerobic exercise is that it can fully stimulate the functions of the blood circulation system and respiratory system, thus contributing to the normal function of the whole body. When your blood circulation system is at its best, the blood flow to the penis will certainly increase.
b: Qigong. Qigong has a good health care function. Unfortunately, not everyone agrees with me. Not everyone has the foundation of Qigong. If you have the foundation of Qigong cultivation, no matter what school you learn, you should know that "mind guards elixir field". After meditation, "Qi sinks into the elixir field". When the elixir field is full and hot, the penis will naturally erect, which is called "Qi rises and Yang rises". At this time, it is necessary to maintain this erection until the end of meditation. This is the most natural way to increase penis blood flow. Moreover, if you are a dedicated Qigong practitioner, Qigong will bring you more benefits than these.
2. Local factors: local factors increase the blood flow of penis by stimulating the genitals and surrounding local tissues.
a: Direct stimulation of penis: Deng Xixian of the Ming Dynasty had a detailed introduction in the Romance of Xiuzhen. Let me get rid of the unscientific things (sucking women to nourish the penis) and introduce them to you.
In the most leisurely time of the day (the ancients required that the yin should disappear and the yang should grow before the afternoon, so I don't think it is necessary to force it), in a room with no interference and good air quality. Adjust your mental relaxation, adjust your breathing, and focus on your lower abdomen (Dantian). Rub your hands together, lift your scrotum and penis with your right hand, and massage your left hand under your belly button eighty-one times (it is not necessary to strictly follow this number). Then, hold up the scrotum and penis with the left hand, and turn the right hand under the navel to massage the lower abdomen eighty-one times (it is not necessary to strictly follow this number); Then, hold the penis from the root with your right hand, and swing the penis to the left and right thighs, so as to do countless things. Then, use your hands to rub the penis like ropes. In this process, the penis will erect due to stimulation, so don't bother about it, let alone ejaculate. After such training and stimulation, the penis can slowly increase.
It should be noted that the exercise of directly stimulating the penis should be carried out step by step. At the beginning, do not over stimulate, hoping to increase your penis overnight. Excessive stimulation is easy to cause hyperemia of sexual organs and genital pain. At the same time, excessive stimulation will also cause excessive excitement in the cerebral cortex (sexual center), which is often prone to the occurrence of somnolence. Therefore, we must slowly increase the intensity of stimulation.
b: Direct stimulation of testis: testis is the most important sexual organ (gonad) of men, and its most important function is to produce androgen and sperm. The normal function of male sexual system and organs is maintained by androgen. Therefore, only by keeping the testicular function normal can we have normal sexual behavior. Similarly, when the androgen level is maintained at a high level, the blood flow to the penis during erection will also be maintained at a high level, and the penis will gradually increase.
The "Iron Crotch Skill", which is widely spread in China, is a method to directly stimulate the testes, which has been introduced in detail on my website.
c: Use instrument assistance: use vacuum (negative pressure) pump to make the penis passively congest, so as to increase the blood flow of the penis. Personally, I don't agree with this method. Its biggest disadvantage is that it prevents the blood from flowing back at the same time, resulting in penis congestion. However, long-term penis congestion can lead to capillary exudation, formation of non-specific inflammation, penile cavernous fibrosis (penile sclerosis), and organic impotence. According to American statistics, 20-30% of people who use vacuum (negative pressure) pumps will suffer from penis pain. Therefore, we suggest that you consider carefully.
Appendix: The following data is "the average length of penis erection calculated from 167 patients implanted with artificial penis", which may not be accurate. Unfortunately, we couldn't contact Dr. Jian Bangping to find out why his "patients with artificial penises" need to implant artificial penises. Let's make a reference.
Man, how long are you?
Taiwanese men average 11.2 cm, American men average 12.89 cm
(Kaohsiung) How long does a Taiwanese man's penis become erect?Jian Bangping, a urologist at Kaohsiung Rongmin General Hospital, spent 10 years. From 167 patients implanted with artificial penis, he calculated that the average length of penis erection was 11.2 cm, 1.69 cm shorter than that of Americans, but slightly longer than that of Koreans.
Jian Bangping said that the penis erection of men depends on the congestion of the cavernous body. Generally, urologists investigate the length of the cavernous body of the penis. The cavernous body is buried within the pubic bone, which requires ultrasonic measurement. The literature on the length of the exposed penis is limited.
The report points out that the average length of the penis erection of Taiwanese men is 11.2 cm, with a minimum of 8 cm and a maximum of 14 cm. Wesley, an American urologist, once investigated 80 patients in the United States. The results showed that the average length was 12.89 cm, with the shortest being 7.5 cm and the longest being 19 cm.
Jian Bangping said that in terms of length, Taiwanese are not much shorter than Americans.
Jian Bangping said that the study confirmed that the length of the cavernous body is proportional to the length of the penis erection. The penis length is in direct proportion to the height and may also be related to the race, so it can be inferred that the size of Taiwanese men is slightly larger than Arirang, but slightly shorter than Americans.
Jian Bangping pointed out that Richard Edwards, a Canadian urologist, solicited people from all over the world to measure the size of penis erection on the Internet. Over the past six years, 2545 valid samples were collected. Statistics showed that the average length of white people was 16.5 cm, black people 15.5 cm, Spanish people 14 cm and Asian people 13.9 cm.
It can be seen from these figures that Westerners with high stature are indeed longer than Easterners, but according to the strict survey data of urologists, it is obvious that many people falsely report their size on the Internet.
