How does the penis work?

The penis is the male reproductive organ. It is composed of the glans, which is the head, full of nerve endings, a spongy body that surrounds and protects the urethra, and two corpora cavernosa, which are on the sides.

During erection, these three bodies are filled with blood. This is what allows the penis to grow in times of sexual excitement.

How old does the penis grow?

The penis grows up to 18 years of age. The organ starts to develop at 12 years of age and its length increases until close to 18.

After that, he thickens and reaches his adult state at approximately 21 years of age, when male puberty ends. The global average is close to 14 cm.

What is the average size of a penis?

Between 12 and 16 cm, a penis is considered to be within the global average, 14 cm. In United States the average is 15.7cm but, just out of curiosity, know that the country with the highest average is the Democratic Republic of Congo, with 17.93 cm and the lowest average is Nepal, with 9.3 cm.

So, if you are an adult and your penis is between 12 and 16 cm, your penis is normal size.

The circumference – or thickness, if you prefer – the average is 12.99 cm. The country with the thickest penis is France at 13.63 cm, while the one with the thinnest is Turkey at 8.89 cm, so we’re fine.

But beware: these numbers are based on fully developed adults. So if you’re in your teens, chances are you haven’t reached full size yet.

It is important to know the right way to take the measurement: it should be taken from the top of the penis, starting from the pubic bone (the one at the base of the penis) and going all the way to the end of the glans (the head). In order to know the circumference of your penis, the measuring tape must be wrapped just below the glans on his body.

You can see, by clicking , a super interesting interactive map with results of a global penis size survey from various countries. The map considers 116 nations and has data on length and circumference and even volume. Worth a look.

Penile average: what size by age?

If any doubts arise about the size of the penis, the ideal is to talk to a pediatrician, urologist or endocrinologist who can assess the organ according to tables and proportions.

However, it is important to know that boys of the same age may have different penis sizes, as well as shapes or thicknesses.

Generally speaking, penile growth occurs in four stages of the boy:


Still in the mother’s womb, the penis forms. At birth, the size of the organ is about 3.7cm.

From 0 to 3 years

At this stage, the penis grows about 1.5 cm. Therefore, the average size is 6.2cm up to 3 years old.

3 to 11 years old

At this stage, the penis increases about 1.5 cm. Thus, the average size is 7.7cm up to 11 years old.

11 to 18 years old

The penis grows about 6.5c, until it reaches adult size. Thus, the penile average is close to 14.5 cm up to 18 years.

Sex and the size of the penis

Even though it’s relevant, size is not the main factor during sex. Partner preference is varied. There are those who like the big ones and there are those who like the small ones, and contrary to what porn movies make it out to be, there is a penis that is too big.

Vaginal sensitivity exists throughout the length of the vagina, but is especially greatest in the first few inches of the vagina. The clitoris, the female sex organ intended only for pleasure, is above the entrance, but it extends inside the female body, skirting the vaginal walls for the first few inches, and can be stimulated from the inside.

That’s why, if your penis is below average, you don’t have to worry so much about sex. Knowing what your partner or partner likes is most important, and it varies from person to person. Chat, discuss and discover your company’s preferences, and your ability to provide pleasure will increase much more than if you were simply a few inches more.

Does smoking shrink the penis?

In a way, yes. Smoking affects every organ in the body negatively and that includes the penis. One of the effects of cigarette smoking is the partial or total blockage of blood vessels, making blood circulation difficult. These blockages can cause less blood to reach the penis during an erection, causing impotence.

Even when a smoker with blockages in the vessels caused by cigarettes can achieve an erection, the penis is not fully erect. Over the years, it can lose part of its maximum size, which can decrease by up to 1cm over the course of a person’s life.

Bent penis: is it a problem?

No, it’s not! A bent penis is common. As long as there is no pain during penetration and it is not disturbed by the angulation of the penis, there is nothing to worry about.

There are several causes for a crooked penis. If the urethra does not keep up with the growth of the corpora cavernosa, for example, it may bend to one side. It can also happen that one corpus cavernosum grows larger than another, some congenital diseases, as well as traumas such as penile fractures.

Wait a minute, can the penis break?

The penis doesn’t have bone, but it can break, so you better be careful with it! Fracture is rare, but it can happen.

The corpora cavernosa and the spongy are each protected by a layer called the tunica albuginea. This layer is very resistant and flexible. When the penis is erect, it also stretches, becoming thinner and more sensitive. If any force bends the penis, the albugineal tunic may break. It’s what they call a penile fracture.

With the tearing of the tunic, the blood present in the corpora cavernosa or in the spongy leaks to the other tissues of the penis and may travel to the scrotum.

In most cases, penile fractures happen during sex. Often when the woman is on top. It happens when the penis escapes from inside the vaginal canal and, when trying to penetrate again, it meets the partner’s hip, bending.

A fracture only happens when the penis is erect and you can hear a crack that may sound like a bone breaking. The penis loses its erection and it hurts a lot, in addition to having bruises on the body due to the leaking blood.

It is necessary to seek medical help as soon as possible, as the rupture of the tunic albuginea, if left untreated, can have several consequences such as permanent deformity of the penis, pain during sex and even impotence.

Growers and showers

If you’re a man, you may have found yourself in a men’s locker room where several colleagues were changing, and chances are you’ve compared yourself to the rest, concerned about your size. Good to know about the difference between growers and showers.

The word grower comes from grow, in English, “to grow”. Most men fall into this category. The penis, when flaccid, varies from 3 to 6 cm, and when it becomes erect it can double and even triple in size.

Shower comes from show, from English, to show. The shower is the one that shows itself. The penises of showers, when flaccid, are from 9 to 11 cm, but unlike growers, they do not grow much when erect.

Now that you know this, if you’re a grower and see a colleague in the locker room who looks huge, even flabby, you don’t need to be embarrassed or think your penis is small. Growers grow a lot, showers grow not much and, in the end, when erect, the average is the same.

Can I enlarge my penis?

There are some promises for penis enlargement, even when there is no medical need for it. However, it is worth pointing out that they are obviously not recommended. Understand:

Magic Penis Enlargement Formulas

First, let’s talk about the internet. You may have already received an email or seen some internet advertising that promised to enlarge your penis. Penile pumps, miracle remedies, dozens of techniques that “makes doctors awe” or any variation on that.

None of these techniques are scientifically proven. Most of them are scientifically refuted, being classified as ineffective. In addition, surely many of them have left doctors really impressed, after all, there are “techniques” extremely dangerous on the internet. It’s better to stay away from it.

Nobody wants to be impotent because they bought something to inject into their penis, or worse, have necrosis and need to amputate it.

Surgical augmentation

There is no approved medical procedure or surgical technique that enlarges the penis. There are experimental surgeries that, by law, can only be performed in an academic environment. Furthermore, the risks are enormous.

There are many blood vessels in the organ and they are essential for the penis to function. Anything that goes wrong with the surgery can compromise your erection ability. There are some cases where a doctor may recommend surgery, but we’ll talk about them in a moment.

I have a small penis, now what?

Some situations can make a penis look smaller than it is. Obesity, for example, causes fat accumulation in the pelvic region and the base of the penis can be tucked into the fat, making it appear smaller.

Pubic hair also causes this same effect. Waxing can give the impression that the penis is bigger.

If your penis is undersized, don’t worry. Your sexual capacity is not diminished by this and it is possible to give and receive pleasure. Size isn’t everything.

Stay away from the internet’s miracle methods to enlarge your penis. It’s been said before, but it doesn’t hurt to remember: there is no scientific proof that they work, and many are dangerous.

I have a micropenis, now what?

It is estimated that approximately 0.6% of men have the condition called micropenis.

A micropenis is defined as being far below the population average. Compared to the rest of the population, in an adult, the micropenis is less than 4 cm when flaccid and 7.5 cm when erect.

Some of the identified causes include lack of growth hormone, lack of testosterone during pregnancy, and various genetic syndromes. Some cases of micropenis can be treated with testosterone injections in early childhood and phalloplasty surgery is available for certain cases.

Phalloplasty surgery

This surgery is a penile reconstruction. Tissue from other parts of the body, often the arm, is removed and placed in the penis to regain its function in cases where the organ is damaged. It can also be used for micropenis cases.

The procedure is very complicated and risky. The tissue may not survive transplantation, which can lead to necrosis, infections, urethral fistula, and thrombosis.

Loss of sensation is common and approximately 30% of phalloplasties present complications and must be removed. All of this can cause sequelae in people with healthy penises.

Suspension Ligament Surgery

Superior ligament surgery is another type of procedure that can enlarge the penis. It consists of cutting the ligaments above the penis, connecting the organ to the pelvic bone. This ligament serves to keep the penis, when erect, stabilized, facilitating penetration.

Such an intervention allows the penis to move further away from the pelvic bone, making it appear larger, at the cost of stability. However, surgery also has risks. The penis can lose sensation as well as erectile ability.

Penile enlargement procedures are not recommended by doctors and most surgeries are performed on men with normal penis size.

Penis Health Care

Penis health is another very important thing. You must not be careless:


Keep yourself clean, okay? Cleaning is essential to avoid bad odors, in addition to keeping your little friend healthy.

It is important to wash the foreskin (the skin covering the glans) with soap and water every day to prevent infections and illnesses that can attack the penis.

The use of condoms is essential in sexual relations with people whose genital health is unknown, to avoid STDs.

And I’m saying this again, because it’s important. Stay away from ads that promise to enlarge your penis. You don’t need them and they can be very dangerous.

Now you know a little more about your penis. Remember hygiene, don’t worry so much about size.
