The size and length of a man's penis is determined by fate

Don't waste your time. Size is determined by fate. However, since so many people prefer large penises, we can't help but ask: Is there any way to make a small penis bigger?

The answer is: No. Since there are no muscles in the penis, no matter how hard you try or how much you exercise, you cannot change its size.

But there is one thing that makes people excited: when a man has an erection, there are several muscles at the base of his penis that can be controlled by consciousness to expand and contract, and can increase the hardness of the penis during erection - although this increase is temporary. According to Dr. Zieberg, professor of urology at the University of Washington and one of the authors of the book "Biopower: A Guide to Successful Sex," these muscles will contract involuntarily after ejaculation because they actually have both voluntary and involuntary characteristics at the same time - although it looks a bit strange.

However, the final conclusion remains the same: even exercise can't help its size.

Dr. Renis succinctly summarizes it this way: "No matter whether it is exercise, drugs, creams, vitamins, hypnosis, injections, or the hundreds of other methods that you can use to order products directly from the back of magazines, it is impossible to increase the size of the adult male's penis."

However, she also comforted people with a few words: Some men think that their penis is shorter than that of their peers, but in fact it is because of the different angles from which they are looking. You should know that when you look at your genitals from above, they will appear shorter than when you look at them from the side. Try glancing at your genitals in the bathroom mirror and comparing them to what you see when you look down from above.

The life and death issues on the penis are the same as those on other parts of the body. The penis itself also suffers from some hidden concerns of its own: Curvature direction: According to the information listed by many men, some of their penises are tilted to the left, and some are tilted to the right. In fact, as long as it doesn't hurt and doesn't affect sex, there's nothing wrong with it; however, some men will experience painful penile erections because their urethra is shorter than the length of the penis. In more serious cases, it can cause painful penile twisting. Painful penile erections can also be cured through surgery.

There is another situation, that is, another kind of erectile curvature is prone to occur after the age of 40, which is usually caused by Peyronie's disease (for details, please refer to the "Peyronie's Disease" section in this book).

Penis fracture: Can a penis break? Believe it or not, it is possible for a penis to break, although it is not likely to happen. This situation can only happen when the penis is stuck in the female pelvis and cannot be ejaculated. At this time, you will hear a breaking sound that you will never forget, and it will also be extremely painful.

According to experts, this terrible phenomenon is caused by damage to the corpus cavernosum or the tunica albuginea connective tissue, or both. At this time, you must not care about your face anymore and should see a doctor immediately. Generally, it can be corrected through surgery. Otherwise, any delay will cause irreparable consequences that can never be repaired.

Cancer: Penile cancer is a relatively uncommon cancer, with only about 1,000 cases reported worldwide each year. Still, the numbers are daunting, since a quarter of the men die and the rest have little chance of saving their penises.

How does penile cancer occur? The specific mechanism is still unclear, but one thing is beyond doubt: the occurrence of penile cancer is definitely related to your bad hygiene habits. Therefore, the best way to prevent penile cancer is to keep the penis clean. Obviously, uncircumcised men are more susceptible to this disease because the intact foreskin is prone to accumulate dirt and cause bacterial infection. If you don't want to be circumcised but don't want to risk penile cancer, just be a little more diligent about cleaning. Circumcision is very common in the United States. In Sweden, however, circumcision is extremely rare. But because the Swedes are so thorough in cleaning their bodies, their rate of penile cancer is not much different than that of Americans.

Testicles

In English, testicle means "witness", which is actually a Latin joke imposed on the world by hypocritical doctors in the Middle Ages. But before the invention of football, almost all cultures called it a "ball," which is a slight deviation because it is actually egg-shaped.

Compared with the eye-catching penis, the testicles can be described as silent workers, quietly doing a lot of hard work, such as ejaculating large amounts of semen and regulating the amount of sex hormones entering the blood.

Like cool places

The testicles are located in a fleshy pouch that hangs from the scrotum. Why didn't God store the testicles, this delicate bean-shaped gland, inside the body, but instead left it outside the body? He should know that there is almost no man who has not experienced the excruciating pain of having his testicles kicked or hit, and this is all because of leaving them outside the body.

However, it must be left outside the body. It can be explained like this: while romantic lovers like to flirt in a warm environment, the testicles "like" to stay in a cool place, which is why they are hidden in an adjustable leather bag and hang down from the body. In fact, strictly speaking, this is because the testicles cannot produce sperm in such a high temperature environment in the body. They must be kept at a lower temperature of about 94 degrees Fahrenheit to ensure that their reproductive function is intact. If hung outside the body, when the external temperature rises, the levator testis will lower the height of the testicles, thereby cooling them down; and when the external temperature drops, the levator testis will raise the height of the testicles, thereby heating them up.

Dr. Siber reminds everyone that although the testicles are exposed to the body, surprisingly, they rarely suffer serious damage. Sometimes, a strong blow to the groin can cause twisting of the spermatic cord. At this time, the arterial blood flowing to the testicles can continue to supply blood to the testicles even though the pressure inside the twisted spermatic cord increases. On the contrary, the venous blood of the testicles cannot overcome this resistance and is retained in the testicles, causing the testicles to become congested and swollen. Dr. Shiber warns that if the congestion is not treated urgently within 4 to 8 hours, the testicles will "slowly decay and die." After a day or two, it will swell like a grapefruit; after 2 to 3 months, it will slowly shrink to the size of a pea - at this point, it is already a lifeless wreck. Dr. Siber urges that patients with severe testicular swelling, bleeding or bruising should immediately seek medical attention from a urologist or other physician to avoid lifelong regrets.

The Little World of Testicles

The testicles float freely at the end of the spermatic cord, like astronauts walking in the vast space. The so-called spermatic cord is made up of blood vessels, nerves and other tubes, and is responsible for connecting the testicles to the rest of the body.

The testicles are enclosed in a fluid-filled scrotum, rather than being in direct contact with the outside world and floating around at will.

If further subdivided, the testicles can be divided into 250 small units, each of which contains numerous seminal tracts that are twisted and tangled into a maze-like structure, and the seminal tracts are where sperm are produced. Once the sperm matures, it carries its magical genetic code into the seminal vesicle and epididymis. The epididymis is a small structure consisting of many thin tubes that spirals behind each testicle. Sperm reside here until orgasm, when they are ejaculated through the vas deferens. The vas deferens is the passage that connects the spermatic cord to the penis, and it is also the part that is cut when men undergo sterilization surgery.

Deep inside the testicles, Leydig cells are busy producing the male hormone, testosterone, which is both the fuse that ignites sexual desire and the main driving force behind the appearance of secondary sexual characteristics in men during puberty, such as beards, increased muscle strength, and a deepening voice. Although under normal circumstances, the two testicles of humans work together to synthesize sperm and testosterone and produce male secondary sexual characteristics, in fact, all these functions can be completed independently by one testicle - doesn't it sound interesting? Then why do we need to grow two testicles? Dr. Berg, professor of urology at the University of Washington and co-author of the book "Biocompetence: A Guide to Successful Sex," believes that "one of the testicles is a storage device."

Dr. Berg also explained: "In fact, the two major functional systems of the testicles, namely the testosterone production mechanism and the sperm production mechanism, are separate, and the latter is more fragile and more vulnerable to damage than the former." This is why some infertile men have healthy and perfect sex drives and do not have erectile dysfunction.

But this does not mean that the testosterone production mechanism can be harmed at will and does not need to be taken care of. For example, an epididymal infection, commonly known as epididymitis, is a common, extremely painful infection. The pathogenesis is usually retrograde infection of the urinary tract by bacteria into the epididymis. Because there are many tiny valves in the testicle that allow sperm to pass smoothly and go "up" into the epididymis; and these valves can also prevent the bacteria in the epididymis from roaming "down" into the testicle and destroying the testosterone production mechanism of the testicle. This is why we often see men infected with epididymitis whose epididymis is swollen and painful, but their testicles are intact and there is nothing wrong with them.
