8 Things You Didn’t Know About Your Penis

1. Use or inspect

You need to lift an erection regularly to maintain the shape of your penis. “You have to exercise mainly,” says Tobias Kohler, assistant professor of urology at the School of Medicine at the University of Southern Illinois.

To maintain healthy tone, the smooth muscle of the penis must be periodically enriched with oxygen due to the pressure of the blood that lifts the penis and makes it erect, says Kohler.

If a person is physically able to have an erection, but has never had an erection during the day, they may find themselves in very unpleasant conditions for a long time, without needing to worry. The brain has an automatic built-in penis maintenance function.

The pulses of the brain cause an erection during the sleep stage of sleep, called the stage of rapid eye movement. It does not matter if you have a sexy dream or a nightmare to end a nightmare: your penis is difficult during that period of the sleep cycle.

But some men are physically unable to have an erection, such as those who have suffered the trauma of the nerves involved or who have been damaged in the nerves or blood vessels caused by diabetes.

“If they do not do anything to maintain a normal erection, they will reduce the penis,” says Kohler. Without a regular erection, the tissues of the penis can become less elastic and shrink, making the penis 1-2 cm shorter.

A device such as a vacuum pump, which forces the penis to inflate the blood, can help men with erectile dysfunction maintain a healthy penis, says Kohler.

2. Your penis can be “farmer” or “show”

Among men, there is no consistent relationship between the size of the soft penis and the total length of the erection.

In a study of 80 men, researchers found that increases in smooth to erect lengths ranged widely, from less than a quarter of an inch to 3.5 inches more.

Whatever the clinical significance of these data, the importance of the costumes is significant. You can not assume that a guy with a big penis tends to stand up. A man whose penis looks small can have an astonishingly large erection.

An analysis of more than 1,000 measurements made by sex researcher Alfred Kensi shows that the shortest soft penis tends to earn double the height.

The penis that does not gain much time with erection is known as “show-er”, and it is said that the penis that earns a lot is “farmer”. These are not medical terms, and there are no scientifically proven thresholds for what is offered or cultivated.

Kinsey’s data indicates that most of the penis are neither opponents nor farmers. Approximately 12% of the penis gained a third or less of its total length with the erection, and approximately 7% doubled its erection length.

3. The fun zone.

Many men consider that the lower part of the glans (head) of the penis and the lower part of the spine are more sensitive to sexual pleasure.

The researchers asked 81 healthy men to assess sexual sensitivity in different areas of their bodies, including not only the penis, but also areas such as the scrotum, anus, nipple and neck.

The lower part of the glans and the lower part of the spine was the highest degree of sensitivity for the vast majority of men, followed by the upper part of the glans, the left and right sides of the glans, the sides of the penis, the upper part of the spine and the foreskin (for a minority of men who are not circumcised). The results of the study were published in the British Journal of Urology in 2009.

4. Allergy with low age.

Studies show that the penis constantly loses sensitivity with the progression of age, making it difficult to quantify accurately. This is because different researchers have used different ways to stimulate the penis and measure sensitivity.

In general, the sensitivity of the penis is measured with the least amount of stimulation a man can feel. This is called the “sensory limit”.

Despite the differences between the studies, the data show a clear direction when taken together. After 25 days, the sensitivity begins to decrease. The greatest reduction in sensitivity is observed between 65 and 75 years.

What is less clear is whether men are already noticing a loss of sensitivity as they get older.

If they know, says Kohler, his patients rarely mention it.

“It’s a very strange complaint,” he says. “On the other hand, erectile dysfunction and difficulty in ejaculation are more common.”

5. The vibrator also works on the penis.

Vibrator is not only for women. They also work on the penis. In fact, the vibration is very effective on the penis, which is often performed by men with spinal cord injuries with the help of a special medical vibrator. For this type of treatment, the vibrator is usually placed on the lower part of the head of the penis.

“Medical class vibrators are not necessarily stronger,” says Koehler. The vibrators are tuned to stimulate parts of the nervous system involved in ejaculation. “It works at frequencies or at a more specific amplitude of [nerve] pathways.”

Most men do not need a medical vibrator to stimulate orgasm. “When patients see late ejaculation, the difficulty of reaching orgasm, they suggest that they are trying to buy a personal massager that shakes from the store,” says Kohler.

Although shakers often help men who suffer from ejaculation problems, it is not necessary for them to have any type of medical condition to use them. You could do it just for fun.

6. There is more to the penis than meets the eye.

“Most men take pride in knowing that the penis has double what they think,” says Kohler.

That’s because half the length of the penis inside your body. Just as you do not see every large oak on the ground, you can not see the root of your penis sitting in the tub and stuck to the pubic bone.

As seen in the MRI image, the erect penis has the form of a vagabond.

7. Your penis is a habitat.

The skin of your penis is home to a variety of bacteria.

Lance Price, PhD and Cindy Liu, researchers from the Genomic Research Institute, used Flagstaff, Ariz. Genetic tests to determine the bacteria in the rods of men. Their study showed that there are a total of 42 unique species of bacteria that live on the skin of the penis.

“We see that the human body is basically a basic system,” says Price.

The study showed that the uncircumcised penis and circumcision did not have the same diversity and abundance of bacteria. The researchers first analyzed samples from the palace of 12 men who planned to circumcise. The samples were taken and analyzed again after male circumcision.

After circumcision, there were fewer bacteria in the bars of men. Many bacteria are less common or absent after anaerobic cleavage, which means they do not need oxygen to grow.

The inner fold of the foreskin is a mucous membrane, like inside the eyelids of a person. The price says that some anaerobic bacteria thrive in that environment but not on dry skin.

“It’s like cutting forests,” says Price. “You will get more sunlight and radically change the environment.”

The study was conducted in Uganda, and all the men who studied were Ugandan.

Liu says he expects some variation in the bacteria found in men in other parts of the world. “I think there is certainly diversity even among Uganda’s own men,” she says.

But researchers are less interested in scanning the rodent bacteria in the world than in understanding the changes caused by circumcision.

Your research may help explain why circumcision is related to the risk of HIV infection. One theory is that anaerobic bacteria can cause the immune system to respond so that cells are more vulnerable to HIV infection.

8. Most men are not circumcised

According to the 2007 report of the World Health Organization (WHO) and UNAIDS, approximately 30% of men over the age of 15 are circumcised.

Rates vary widely depending on religion and nationality. Almost all Jewish and Muslim males in the world have a circumcised penis, and together they account for almost 70% of all circumcised men worldwide.

Some research shows that there may be health benefits of circumcision. For example, circumcised men may be less likely to transmit sexually transmitted diseases to their female partners or develop penile cancer.

“The evaluation of current evidence indicates that the health benefits of circumcision of newborns outweigh the risks and that the benefits of the procedure justify access to this procedure for families of their choice.” The specific benefits identified include the prevention of pathogenic infections of the urinary tract, cancer of the penis and the transmission of some sexually transmitted diseases, including HIV. “This statement was also adopted by the American College of Obstetricians and Gynecologists.

In recent years, many studies have shown that circumcised men are less likely to become infected with HIV. WHO and the Joint United Nations Program on HIV / AIDS (UNAIDS) are recommending male circumcision as a measure to prevent HIV. “There is conclusive evidence that male circumcision reduces the risk of HIV infection of two different sexes in men by approximately 60 percent,” says the WHO.
