Features of the structure of the penis of a man

The penis is the external genital organ of a man, which performs a number of tasks and functions. With the help of the penis, a man can defecate, and this body also directly participates in sexual intercourse and the fertilization of a woman for further offspring. The quality of the man’s sexual life and activity directly depends on his health and normal development, so you need to know the structure of the head of the penis and the organ itself.

As practice shows, every man is interested in the shape, size and functioning of his penis. And any diseases associated with it cause not only physical, but also psychological discomfort up to the development of depression. Therefore, any representative of the stronger sex needs to know the anatomy and structure of the penis, its features and risks of developing diseases.

The structure of the head of the penis
The penis itself in its structure involves three departments - the base, trunk and head. But most of all, the medical certificate and the anatomy of the structure of a person devotes attention to the head. There are no men who do not know what a penis head is, what it looks like and what it is intended for. But there are those who do not know the full structure and features of this section of the penis.

The head of the penis is the final part of the penis covered with foreskin. A head is formed by the expanding end of the spongy body inside the penis trunk. Thus, it is believed that the head is the outer end of the spongy body and penis with the shape of a blunt cone, which has a rounded tip. The protruding part of the head is called the “whisk".

Inside the head of the penis contains the extreme part of the urethra, thanks to which the man makes the process of urination. If the penis is in an excited state, an ejaculation takes place through it, which is intended to fertilize the female germ cells, so that the partners give offspring. In this regard, the head of the penis is involved in reproductive function.

The head structure also includes a large number of nerve endings, which is why it is extremely sensitive to touch. In addition, the head is the most erogenous zone on the man’s body; it is responsible for the reflex onset of ejaculation. The part of the head is also considered - the foreskin, its inner leaf moisturizes the head, and on the lower side of the penis the foreskin passes into the bridle.

What are the types of penis?
Today, urologists offer a classification of what types of penis heads are. It includes the following varieties:
- curved or curved - in this case, a slight curvature in different directions can be both on the head itself and on the stem of the penis,
- cylindrical - a common head shape with an even base without veins and irregularities, as well as without a pronounced transition between the diameter of the stem of the penis and head,
-conic - in this case, the thick trunk of the penis at the base gradually tapers to the very head,
- mushroom - visually the head of the penis resembles a mushroom cap, but the trunk of the penis will be much thinner than the diameter of the head,
- barrel-shaped - a penis of small length has a bulk thickness, and during an erection it visually resembles the shape of a barrel,
- the correct form - each nation and nation has its own individual concepts of norm,
-arrow - from the base to the head, a narrowing of the trunk of the penis is observed, but during an erection the organ swells,
reminding visually an arrow.

Unusual forms of the penis and its head, which are quite rare, are also considered separately. For example, the shape of a graviola or a wide short penis with massive testes, a C-shaped penis with a curvature to the right, a banana shape when the head of the organ tends to the south with a bend of 10 degrees, and much more.

Features of care and disease prevention
If a man does not comply with the norms of hygiene of the penis, the risks of developing diseases increase at times. The most common of them are phimosis or pathological narrowing of the foreskin, as well as balanitis or an inflammatory process in the head area. It is possible to prevent inflammatory and infectious processes in the groin area by observing the following rules:
- a shower with soap 1-2 times a day,
-regular change of underwear,
- depilation or epilation of excess hair in the groin area,
- the ratio of free linen from natural fabrics.

Experts advise men to also rinse the head area from smegma when moving the skin with the foreskin back to fully expose the head. To prevent diseases of the penis and head can also be protected by sexual intercourse with the use of barrier contraceptives, as well as the avoidance of accidental connections. For any alarming symptoms (redness, itching, burning), you should immediately contact a urologist.

Conclusion
The penis of a man consists of several departments, it is extremely important for a man to know the structural features of the head of the penis. It consists of the foreskin, frenulum, urethral opening, and also a large number of vessels and nerve endings are included in it. The head is needed to remove urine and sperm, to develop an erection during sexual stimulation, as well as to enjoy sexual intercourse.

Male penis anatomy

The structure of the genitals of men

The anatomy of the male penis is a rather complex issue requiring detailed study. Not so little attention was paid to him, since the penis is a symbol of the preservation of the human race and fertility.

The male genital organ consists of the following elements:

  1. Penis body.
  2. Foreskin.
  3. The mouth of the urethra.

The lower part of the penis is called its base. It can also be called the root of the penis. In this area, he hides in the pubic bone. On the back, the penis connects to the scrotum.

The basis of the member is the trunk or its body. The end is called the head. It is considered the most sensitive area, which is highly responsive to any external impact. Stimulation of the head allows a man to achieve orgasm.

The anatomical body of the penis has its own components. It includes two cavernous bodies and one spongy. Due to this structure, the genital organ increases in size with a sufficient rush of blood. So an erection is achieved, without which sexual intercourse is impossible.

Under these structures is a spongy tissue. It hides a channel connected to the bladder. This element is also associated with the vas deferens.

When a member is in a calm state, it performs an exclusively urinary function. During an erection, the ejaculating also joins.

The ends of the cavernous bodies cover the edge of the head. Due to this, a small thickening is formed, behind which there is a coronal groove. Such anatomy of the penis and its structure are inherent in all men who do not have abnormal abnormalities.

The penis has the foreskin. This is the name of a very thin peel that is susceptible to any effect. The foreskin is elastic. From the bottom of the penis, it connects to the scrotum. This transition in some men gives an obvious seam.

In the penis, there are also vas deferens. They allow seminal fluid to come out.

Features of the structure of the penis

What does the penis consist of? The penis of a man (phallus, penis) has many structural features. All elements of the reproductive system of the male body can be divided into external and internal. The external elements include the penis, which consists of the following parts:

  • Base (root)
  • Trunk (body),
  • Head.

How does the penis work? The base of the penis is attached to the bones of the pubic joint. Two types of bodies are involved in the formation of the trunk: spongy and cavernous. They contain a large number of recesses that can easily be filled with blood. At the end of the phallus, the spongy body is expressed by a thickening of a conical shape - the head of the penis. Its edge covers the ends of the cavernous body, fusing with it. Thus, a thickening around the circumference (corolla) is formed, followed by a coronal groove. The head has a delicate coating of thin skin, called the foreskin, on which there is a large number of glands that produce smegma (a secret that acts as a lubricant).

The head of the penis is equipped with many nerve endings, which gives it increased sensitivity when touched. The trunk of the penis also has a high sensitivity. In the upper region of the head there is a hole - the exit of the urethra, through it the excretion of urine and sperm.

The foreskin of the penis can partially or completely cover the head. On the back of the penis there is a junction of the foreskin with the head of the penis through a longitudinal fold - a bridle. Between the foreskin and the head of the phallus there is a slit-like cavity, the formation of which usually ends by the age of two. In it, the accumulation of smegma most often occurs.

As they grow older, signs of hair follicles appear on the body of the penis, and later on, hair develops from them. In the penis is a large number of veins, blood vessels, bulbourethral glands, the prostate - all this ensures the normal functioning of this organ. Most of the internal parts of the genitourinary system are hidden, but with the help of palpation you can find the prostate and testicles.

Anatomy and physiology of the head and adjacent structures

The head has approximately the shape of a cone with a rounded apex or hemisphere having an extension below.

The bottom edge of the head is whisk - wider than the body of the penis at the place of their fusion, and under the corolla, the narrowing of the body of the penis forms a coronal groove. It is its growth when articulated with the cavernous bodies of the body of the penis. The corolla and coronary sulcus have the highest sensitivity to mechanical erogenous stimuli in the male body, and the corolla often serves as the main source of male sensations during intercourse when rubbing against the woman’s vaginal walls, which are necessary for reflexive orgasm with the release of seminal fluid, which ensures fertilization of the egg in the cavity female internal genital organs.

The coronal groove is ring-shaped and serves as a place for attachment of the elastic protective skin of the penis. The farthest part of this skin tube attached to the coronal groove from the male body is called the foreskin of the penis. Outside the phase of sexual arousal, the foreskin hangs freely, covering the penis head with its inner leaf to protect it from damage and sometimes continuing for various small distances beyond the outer end of the head and thereby protecting the external opening of the urethra. It covers the hole from the sides, but usually does not close it, although due to its mobility it can move sideways and deflect a stream of urine coming out of it.

The penis consists of elastic ones in a calm state and capable of blood supply for erection of longitudinally cavernous and spongy bodies located in it. They form its trunk, covered with leather on the outside. Most of the trunk is formed by cavernous bodies in thickness, between which from the lower side there is a spongy body, inside which passes the urethra. The stem of the penis ends with the head into which the spongy body passes. Accordingly, like the trunk, the head is capable of blood supply during erection, in which it also increases in size.

Normally, at the top of the head is the external opening of the urethra (urethra). It is a small vertical gap, covered with equally small elastic protrusions - sponges. They reflexively move apart during urination and ejaculation and can be diluted a short distance from the outside if the medical personnel need to introduce diagnostic tools to the urethra for diagnostic examination of its lumen and cavity of the bladder (cystoscopy cystoscopy device), as well as a catheter for emptying the bladder in cases of impossibility of its natural emptying during the growth of prostate adenoma compressing its neck or specific damage to the part of the spinal cord that controls the slave the pelvic organs (bladder catheterization). In congenital developmental disorders, the external opening of the male urethra can not be located on the top of the head (hypospadias), but in case of epispadias, the wall of the canal can be split to one degree or another, and the head itself, or partially or completely, can be split penis.

The cross section of the head is not perfectly round, since a longitudinal furrow extends into its lower surface. The suture formed by the furrow runs along the entire body of the penis and continues on the scrotum. Furrow and suture occur during embryonic development during infection urogenital sulcus (cleft), which is characteristic of the embryo before the stage of its sexual differentiation, which does not grow in this way in embryos, which in the next stages will develop according to the female type, and turn into a sexual gap in them, containing the vestibule of the vagina, surrounded on the sides by pairs of small and large labia . Larger than usual non-growth of this sulcus in males is epispadias or hypospadias.

Sexual physiology of the head

Head with an erection less source not specified 1534 days more elastic than the body of the penis, which reduces the risk of injury to the female genital organs during sexual intercourse. In addition, the head is always more sensitive than the rest of the penis, as it is rich in nerve endings. The most sensitive is its lower part - the crown (crown).

In the lower part of the glans penis is a bridle, which during intercourse pulls the head down so that its crown enters into contact (rubs) with the walls of the vagina, exciting nerve endings in the crown (crown) of the head and nerve endings of the vagina. The urethra and ejaculatory canal extends into the glans penis in the form of a small gap from 3 to 5 mm.

The glans penis is pierced by glands that keep its surface moist.

The head is the most sensitive erogenous zone in men, and most often it is the achievement by the nerve endings of the limit of excitation that serves as a reflex signal for ejaculation, completing the active part of sexual intercourse. If ejaculation occurs too quickly (especially before the introduction of the penis), then specialists can talk about premature ejaculation. To eliminate this problem, various medical technologies are used, in particular, to reduce the sensitivity of the head. For example, her exposure outside of sexual intercourse. After exposure, it will often be exposed to environmental influences. A radical means of this exposure is circumcision of the foreskin, more moderate is the displacement of the foreskin by the head and its holding there by special retractor rings held by the corolla of the head in the coronal groove. However, it is physiological by nature to cover the head with foreskin to moisturize it and protect it from injuries.

Homologist heads in women

In women, the head of the penis matches the genesis, shape and richness of the sensitive nerve endings for erogenous function of the head of the female penis - the clitoris, which normally has significantly smaller dimensions than the penis. In most cases, this is the only part visible outside the clitoris, whose body is hidden in the pubic joint. With sexual arousal, she, like the entire clitoris, swells and is extremely sensitive to touch. It is also covered to varying degrees by its protective fold of skin - the foreskin of the clitoris - and is connected to it by the bridle.

Hygiene of the head and foreskin

Before puberty, the foreskin usually does not separate from the head of the penis. Upon reaching puberty, between the foreskin and the head in the area of ​​the coronary sulcus separating the head from the body of the penis, viscous whitish discharge appears - smegma, which serves as a lubricant and moisturizer to protect the sensitive area of ​​the body from drying out and irritation. However, their accumulation can lead to an unpleasant odor and the formation of an environment for the propagation of pathogenic bacteria that cause inflammation, therefore, among other hygienic procedures, regular smegma removal with cleansing of the head and foreskin by washing off smegma and / or wiping surfaces with means for male intimate hygiene is required. it becomes possible when the skin of the penis with the foreskin is retracted to completely expose the head. The history of medicine believes that, since in the conditions of a hot desert climate with its inherent lack of water for ablutions in the peoples of West Asian countries, such inflammations could occur frequently, and their causes and methods of prevention were not obvious, it was precisely to prevent them in the religions that arose there (Judaism , and then Islam) circumcision was introduced, after which the head of the penis is constantly naked and smegma does not have the ability to quietly accumulate in the surrounding recess. For hygienic reasons, circumcision has begun to be practiced outside of these religions, especially in the United States of America. Nevertheless, by nature, the foreskin is not superfluous, since it serves to protect the easily injured head of the penis from external influences and, subject to the hygienic standards of inflammation in this area, can be avoided.

Pathological conditions of the glans penis

As with other organs, pathological conditions here can be congenital and acquired, acute and chronic, infectious-inflammatory and non-infectious (for example, developmental disorders).

Developmental disorders and inflammation are associated with the state of both this organ and surrounding organs and tissues. Thus, inflammatory diseases of the head are often accompanied by inflammation of the surrounding foreskin, which can lead to an abnormal narrowing of the latter, making it difficult to remove smegma and urine residues from the gap between them.

The structure of the head of the penis

The penis itself in its structure involves three departments - the base, trunk and head. But most of all, the medical certificate and the anatomy of the structure of a person devotes attention to the head. There are no men who do not know what a penis head is, what it looks like and what it is intended for. But there are those who do not know the full structure and features of this section of the penis.

The head of the penis is the final part of the penis covered with foreskin. A head is formed by the expanding end of the spongy body inside the penis trunk.

The part of the head is also considered - the foreskin, its inner leaf moisturizes the head, and on the lower side of the penis the foreskin passes into the bridle.

How it looks: scheme

In fact, the head of the penis is the enlarged part of the cavernous bodies, which is designed to remove urine and sperm from the urogenital system of a man, have sexual intercourse and get the maximum pleasure from sexual stimulation by a man. To understand how the head of a member looks, it is enough to consider the features of its structure in the following diagram:

What are the types of penis?

Today, urologists offer a classification of what types of penis heads are. It includes the following varieties:

  • curved or curved - in this case, a slight curvature in different directions can be both on the head itself and on the shaft of the penis,
  • cylindrical - a common head shape with an even base without veins and irregularities, as well as without a pronounced transition between the diameter of the stem of the penis and head,
  • conical - in this case, the thick trunk of the penis at the base gradually tapers to the very head,
  • mushroom-shaped - visually, the head of the penis resembles a mushroom cap, but the trunk of the penis will be much thinner than the diameter of the head,
  • barrel-shaped - the penis of small length has a bulk thickness, and during an erection it visually resembles the shape of a barrel,
  • regular shape - each nation and nation has its own individual concepts of norm,
  • arrow - from the base to the head, a narrowing of the trunk of the penis is observed, but during an erection the organ swells,
  • reminding visually an arrow.

Unusual forms of the penis and its head, which are quite rare, are also considered separately. For example, the shape of a graviola or a wide short penis with massive testes, a C-shaped penis with a curvature to the right, a banana shape when the head of the organ tends to the south with a bend of 10 degrees, and much more.

Anatomy: what the phallus consists of

The penis is recognized as the external organ of the sexual structure in representatives of the stronger sex, it is used to carry out a sexual act, to deliver sperm to the woman's vagina, and also to release urine from the bladder.

The main functions of the phallus:

  • The penis is intended for copulation with a sexual partner,
  • Produces the release of seminal fluid,
  • It is an organ for urination.

How is the penis in males?

The base of the penis is attached to the pubic bone structures. Also, the structure of the penis implies the presence of 2 cavernous (cavernous) areas, 1 spongy. Cavernous areas are located on the sides of the organ. They are filled with blood. When excited, an expanding process begins in the area of ​​the cavernous areas, they are poured with a significant amount of blood. The cavernous bodies are similar in shape to cylinders, with sharp endings located in the back, which are divided in different directions, attached to the pubic bone structures. The muscular system of the cavernous region is represented by a fused condition. The albuminous membrane covers the cavernous areas, creating a septum of the penis.

The spongy region is located in the central part of the organ, in the groove among the cavernous parts. The phallus bulb begins with it, it ends with the phallus head, where there is an urethra.

Urethral functional implies

  • Sperm output,
  • Urination.

The device of the urethra looks like a hollow tube, usually it is closed, like a crack, where the tubules begin to open against the duct of urine.

The structure of the penis contains fascia, the skin around the organ. There is no subcutaneous fat in the phallus. On the back of the penis is the venous, arterial, nervous system.

The structure of the penis provides for the possible presence on the skin of the phallus of a small number of hairs, moles, other formations in this place should not be. If a man noticed on his penis various neoplasms, rashes, growths, then he should immediately consult a doctor.

The appearance of the phallus is individual, a straight penis is rare. The size of the penis in an adult male on average at rest is 5-10 cm, in the process of erection - 14-16 cm, corresponding to the dimensional parameters of the woman's vagina. The form of the phallus during an erection, the angle of inclination have individual characteristics. An erect penis of 16-18 cm is recognized as large, and more than 18 cm - of a giant.

In the process of sexual arousal, the volume of the phallus increases 2-8 times, transforming into a dense organ. A decrease in venous outflow supports an erection, this is due to muscle contraction in the area of ​​the root of the penis. Upon completion of the excitation, muscle relaxation is observed, the outflow of blood filling the phallus begins, so the penis is reduced to the usual size.

There are several forms of the phallus:

  • Cylindrical view - the same head, root,
  • Pointed type - a wide base is observed,
  • The mushroom shape is a massive head, but a thin base.

Shape and structure

The glans penis is an enlarged portion of the cavernous body, on top of which there is a small hole communicating the urethra with the external environment. This structure is located on the rounded parts of the cavernous bodies. It is flattened around the circumference of its base, or in other words, the crown, around which there is a recess called a coronal groove.

Head shape depends on the individual characteristics of the organ. There are such forms:

  • Mushroom, she is more common than others,
  • Spiky, more often observed in men with a narrow and long penis,
  • Cylindricalis most rare.

Women prefer to classify this part of the organ as: a small, large and beautiful head of the penis.

Functions

Functions that Performs male penis are simple. Firstly, an urethra opening is located on it, through which urine, semen is secreted. And secondly, due to nerve endings on its surface, during intercourse, the head of the penis (video will be lower) brings basic tactile pleasure.

Penis head sensitivity

Sensitivity of the penis head is provided by nerve endingsthat are located on its surface. Thanks to them, important processes are performed:

  • An erection develops
  • Sperm is being prepared for ejection from the testicles.

They also prevent the early interruption of intimacy, which is necessary for the conception of a child, and provide a pleasant feelingexperienced by a man during sexual intimacy.

How to increase

Sometimes, however, a change in the sensitivity of the penis occurs, it increases or decreases. The reasons for the development of a decrease in sensitivity include:

  • Injuries to this part of the organ, both superficial and deep,
  • Excessively frequent self-satisfaction, in particular with gross, abrupt movements,
  • Underwear that is picked up incorrectly irritates the sensitive part of the penis,
  • The inflammatory process affecting this part of the organ and foreskin,
  • Diseases of the nervous system,
  • Hormonal imbalance,
  • Circulatory disorders in the penis,
  • Psychological disorders
  • Bad habits like smoking, alcohol abuse.

For sensitization You can apply a variety of techniques.

Can be used stimulating ointments or creams, and also allowed the use of tools, such as feathers, with which a woman prepares a partner for sexual intimacy.

To combat this problem, the treatment of the main pathology, which is associated with decrease in sensitivity. May be assigned preparations, massage, use of devices to improve blood circulation in the penis.

How to reduce

In turn, the etiology of the formation of hypersensitivity can represent:

  • Diseases affecting the head of the penis, such as phimosis or balanoposthitis,
  • Increased irritability of nerve endings,
  • Mental factor.

If we talk about how to reduce organ sensitivitythen you can use spray or contraceptive with anesthetic effect. Spend operational option of struggle with this problem. It consists in circumcision of the foreskin, which is considered positive in terms of personal hygiene. Special may also be assigned. massages, wearing coarse cloth underwear in order to reduce the sensitivity of the penis.

We recommend that you watch a video about the causes and methods of reducing the sensitivity of the penis.

What to do if sensitivity is completely gone

If the sensitivity of the head of the penis completely gone you should immediately consult a doctor who will prescribe the appropriate treatment.

You can try to fix this situation yourself, for this it is important to understand head structure, its functionality.

Maybe worth change masturbation technique. To do this, you need to use grease and make sure that all movements and touches are smooth, accurate.

Can train tactile sensitivity. To this end, a man should close his eyes, slowly touch the edge of the phallus, trying to analyze what he feels. After that, the action is repeated, but with the touch of an organ with a tissue, and then with a pen. A man must differentiate his own feelings, note any changes in them. He can also take a piece of ice and repeat the manipulation already with his help.

In order to restore sensitivity, you can use aphrodisiacs and any additional funds that all existing intimate goods stores can offer.

See the video for more information about the loss of sensitivity.

Balanitis

The balanitis is called the inflammatory processhitting the head. The symptomatology of this pathology is quite characteristic.

The first signs are discomfort in this part of the penis, in the form burning or skin itching, especially when trying to bare.

Gradually, it became apparent that she blushed and swollen. Also gradually body temperature rises Symptoms of general malaise develop, such as a headache and a decreased body tone. Smegma formation increases, up to such portions that it soaks underwear or even clothes, may appear purulent discharge. Then the development of symptoms depends on the form:

  • If the disease occurs in erosive or ulcerative form, then, respectively, erosions appear on the surface of this part of the organ, which, progressing, become ulcers. Appears, intensifies pain in the head area, especially painful sensations during movement,
  • If pathology has developed based on candidiasis, then there is severe itching at the end of the penis. Which is combined with the presence on its surface of erosion, as if covered with a whitish film, and under the film erosion hyperemic.At the same time, in the area of ​​the coronal groove, they can appear and accumulate. cheesy character highlightreminiscent of flakes
  • Obliterating disease is characterized by the formation of scarring on the skin surface. These scars have a pale tint, since the skin atrophied in this place. At the same time, a person feels that something is pulling off the skin and he is faced with difficulty urinating.

Phimosis

In essence phimosis, this is a narrowing of the foreskin. In addition, other complaints are most often absent or only the appearance of difficulty urinating, in the form of the need to significantly strain and in general feelings of excitement. A man may even note that urine accumulates first in the cavity under the foreskin. It, in turn, increases, and only after that follows or thin stream or dropwise through a small hole.

And sometimes the symptoms are supplemented signs of inflammation. In this case, the man experiences head pain notes the appearance of purulent discharge directly emerging from a narrow cavity behind the foreskin. Body temperature may also increase, regional lymph nodes may increase, and as a whole a person feels general malaise.

We recommend that you watch the video on when and how to treat phimosis.

Redness

Redness of the head of the penis is not even supported by any unpleasant sensations or its modification, should immediately concern.

The appearance of redness hints at disease onsetaffecting this part of the penis. This may be the first sign of both improperly selected underwear and a serious illness like balanitis or phimosis.

Sometimes it is with redness in this area penis cancer begins to develop.

Denervation

Many men will be interested in the method of combating premature ejaculation, which is called penile head denervation. This method belongs to the category of microsurgical surgery. nerve fiber intersection.

The following diseases of the head of the penis exist:

Why there is pain in the head of the penis

The pain affecting this part of the male penis disturbs and does not allow a normal sex life.

If you are tormented pain in the head of the penis, know, the appearance of this symptom indicates the development of the disease. Moreover, most often pain does not appear in the early stages of the course of the disease, but already during the midst.

The very fact that the end hurts requires a visit to a health professional and careful attention to yourself, in combination with following all the recommendations of a doctor.

How to treat and which doctors to contact

Unfortunately, guys often feel awkward when they encounter any changes or problems affecting their genitals. Because of this, they put off visiting a medical institution for as long as they can, hoping with hope that the situation might resolve itself.

If a man is faced with pain, then he you must immediately contact a urologist.

After all, the reason due to which the pain has developed can progress and cause complications, up to impotence.

Doctor only, after a thorough inspection and analysis results, will be able to make a conclusion about the etiology of pain, choose the right treatment.

The opinion that minor anomalies affecting the head of the penis can go by themselves - wrongly. It is necessary to constantly monitor the state of the phallus, so as not to worsen it and not to face complications of diseases that affect this part of the organ.

Penis blood supply system

After it became clear what the male member consists of, it is worth understanding the features of the device for its blood supply. The anatomy of the penis of a man is quite complicated. The abdominal aorta is divided into a pair of iliac arteries, from each of which an internal iliac artery leaves. Large vessels branch from it to the gluteal muscles, after which this artery is usually called the internal genital. Branches to the perineum, rectum and bladder already leave from it. Passing further the urogenital diaphragm, this blood vessel becomes the artery of the penis, located in a horizontal plane. The last branches of the penis artery are the urethral, ​​bulbous, dorsal and deep arteries. Each of them is a pair, they are joined together by a deep and superficial anastomosis, which ensures effective blood supply to the penis.

Having entered the penis, the bulbous artery is divided into several branches, one of which goes into the spongy body, and the rest remain at the beginning. In the place where the spongy body of the phallus fits into the lower groove, the urethral artery penetrates into it. Further, it passes inside the spongy body to the head of the penis, where it connects with branches of the dorsal artery. First, the urethral artery passes into the capillaries, forming the venous plexus of the mucous channel of the urinary tract, and then goes into the cells of the spongy body. And so there is a supply of blood to the tissues of the urethra and the spongy body of the penis.

The most significant of all the blood branches in the penis are the deep arteries.

Deep arteries penetrate the phallus at the junction of the cavernous bodies into the trunk of the penis. These blood vessels are the basis for the supply of arterial blood to the erectile tissues of the cavernous bodies, which is something like dilated capillaries. As the deep artery moves along the cavernous body, it gradually becomes thinner, giving off the lateral branches. In the upper part of the cavernous body, this artery merges with the same vessel of the opposite side and the last branches of the dorsal artery.

The back artery is equal in diameter to the deep, it acts as a direct continuation of the phallus artery. She goes on his back from an unpaired eponymous vein on both sides, located under the fascia. So she reaches the head, where the end branches form anastomoses. Throughout its journey from these blood vessels there are many branches: to the membranes of the penis, branches give rise to vessels leaving the spongy tissue, as well as arterial trunks that supply blood to the cavernous and spongy bodies and the skin of the phallus. Partially, the skin of the penis is supplied with blood from the external genital artery, which moves away from the femoral artery, and it, in turn, is a continuation of the external iliac artery.

Venous outflow occurs through the deep and superficial veins of the penis, the structure of which implies their communication.

In the superficial vein, blood is collected from the skin and subcutaneous tissue. The vein is located directly under the skin, at the base of the penis it bifurcates, then flows into the large saphenous vein or directly into the femoral vein on each side. From the spongy and cavernous bodies, outflow mainly occurs through the deep dorsal and deep central vein systems. From the center of the cavernous bodies, outflow occurs into the deep veins that leave this area at the site of the divergence of the bodies, then they flow into the urogenital venous plexus. Bulbous veins of cavernous bodies flow into the same place.

Important! The largest vein of the penis is the deep dorsal vein, it has a well-developed valve system.

During sexual arousal, the penis enlarges several times, and it also becomes very tight. By decreasing venous outflow, an erection is maintained. This is facilitated by the contraction of special muscles located at the root of the penis. When the excitement subsides, the muscles relax and the blood that fills the organ begins to flow. So the penis takes its usual size and ceases to be rigid. In an erection state, the head of the penis is always less elastic and more elastic than its trunk, which reduces the risk of injuries to the female genital organs.

Dimensions

The structure of the male penis implies considerable diversity in its size and shape. The penis in boys differs markedly from the penis in men. The normality of the size of the male organ can be judged only by comparing the average indicators. According to scientists, the size of the erect penis varies on average from 12 to 18 cm. The length of the penis in a relaxed state varies from 6 to 10 cm. It should be understood that deviations in both directions are periodically observed, but they are quite rare. During puberty, measuring the size of the penis does not make much sense, since the penis is actively growing at this time. An important parameter when measuring the phallus is its width. Its average value usually varies from 7 to 16 cm in girth when excited.

Important! The size of the male penis is affected by the level of hormones in adolescence. With a large level of hormones, the size of the penis will be larger than with a reduced level. Maintaining a healthy lifestyle also significantly affects body shaping in adolescents.

The shape of the penis is also different. There are 3 main forms: cylindrical (head and base are approximately identical), mushroom-shaped (massive head and thin base) and pointed (broad base). Quite often, curvature is observed, which can only be attributed to aesthetic disadvantages.

As can be seen from the above, the penis of a man is a very complex mechanism that has many nuances of structure and perception, which is a rather subjective issue. In case of any suspicions arising about the health of the urogenital system of men and the penis in particular, it is necessary to seek qualified medical help.

Muscle

These muscles can be strengthened with Kegel exercises.

The structure of the penis (male penis) includes two important muscles:

  • Bulbous spongy muscle. It is located in the area from the tendon center of the perineum. This element is fixed directly to the cavernous bodies. The muscle contracts during ejaculation, due to which sperm is successfully expelled from the body. It is also involved in urination, helping to remove all urine from the penis.
  • The sciatic-cavernous muscle. She is a steam room. The element covers a cavernous body. This muscle is easily felt. To find it, it is enough to raise the penis, which is in an erect state. If it is well developed, then the intimate life of a man will be saturated.

A strong erection in a man is provided by a well-developed sciatic-cavernous muscle. But onion-spongy is more important for a full ejaculation. The stronger it is, the brighter the orgasm.

Blood supply

The genital organ has two important arteries. It is dorsal and bulbourethral. They are associated with the posterior and anterior parts of the penis and are large branches of the genital artery, which are responsible for the correct and complete flow of blood to the male reproductive organs.

It is the arteries that are responsible for the flow of blood, due to which the man has an erection.

Innervation

In the absence of diseases of the genitourinary system, the organ can rise “from thought alone”

The structural features in men of the penis allow it to be a well innervated organ. The dorsal nerve is its most sensitive. The sympathetic nerves exit the pubic region, and the parasympathetic nerves act as an extension of the pelvic nerves.

The excellent innervation of the penis is ensured by the high sensitivity of the penis to any kind of stimulation. In the brain, impulses are transmitted through the nerve endings, after which the man develops excitement.

Head and foreskin

The structure of a healthy penis in a man includes the foreskin and head. The first component of the penis protects the second from possible rubbing on underwear and clothes. If you move the foreskin, then the head is exposed. Such stimulation causes a number of reactions in the body, which ultimately lead to orgasm.

There is a pathology due to which the foreskin of a man is greatly narrowed. It is called phimosis. For this reason, the head cannot be fully exposed. In addition, in the process of moving the foreskin away, severe pain appears. In such situations, stretching the skin or cutting it off is required.

Member size and shape

Size depends on many genetic factors.

The structure of the head and the penis itself are not the most popular topics in men. People are more interested in the shape of the penis and its size.

In newborn boys, the size of the penis is within 4 cm in length. At 12, his active growth begins. By this time, it reaches 6 cm. After each year, the penis increases by a few more mm.

In adolescents 17 years of age, the size of the penis is limited to an average of 8-10 cm. These and other figures were obtained during penile changes in a calm state.

A purely individual is the form and appearance of the male member. Each man will have his own characteristics:

These features are formed in men in adolescence. By the age of 15, a clear curvature of the genital organ appears.

During an erection, the size of the penis changes. It increases several times.

According to statistics, the average penis size in an erect state in an adult male is 13-16 cm.

Individual features and pathologies

The insufficient production of testosterone by the body leads to the fact that the penis may practically not develop

A man may have certain problems with the penis if he has hormonal or genetic abnormalities on the part of sexual differentiation. In this case, it is understood that the structure and size of the reproductive organs does not match the gender of the person. The male penis can initially be very small if the body does not produce enough hormone in the body. Therefore, it is easy to confuse it with the clitoris.

In a man, a urologist will diagnose hypospadias if the mouth of the urethra is not located at the top of the head of the penis.

Representatives of the stronger sex can have both congenital and acquired abnormalities. The latter usually result from damage to the penis. They lead to a curvature of the reproductive organ or narrowing of the foreskin, which is also a pathological condition.

Urination

One of the functions of the genital organ in representatives of the stronger sex is urination. This process is easily carried out when the penis is in a calm state. It is not tense, soft and just hangs from the pubic zone. Urine leaves the organ through the urethra. The intensity of the stream directly depends on the fullness of the bladder and nervous tension of the penis. Also, this process is affected by existing pathological processes that lead to an increase in the prostate. With inflammation and other diseases of the prostate gland, its increase is observed. As a result of this, it compresses neighboring organs, which negatively affects the intensity of the urine stream.

Urine comes out of the urethral opening. She gradually spreads her lips to clear her way out. The jet is different. It can be straight or fan-shaped. Often there is a spray or a split stream. A man is able to independently set her direction if, during urination, she will rotate her body or divert the genitals with his hands in different directions.

Erection

Weak erection or its absence is directly related to the problems of the male reproductive system

Once upon a time, people truly believed that the genitals in men harden during an erection only because it is filled with a lot of air. Only decades later, experts found a true explanation for this phenomenon.

The penis is aroused because it is filled with blood. In this case, the venous outflow from the organ is significantly reduced. As a result of such processes, caverns are filled with a large amount of blood, which increases its volume up to 8 times. Therefore, during an erection, the male member becomes elastic and firm. This allows him to have a full sexual intercourse with a woman.

It is the reduction of venous outflow that provides an erection and its retention for a long time. The onset of such a process is facilitated by the contraction of the sciatic-cavernous muscles, which can be found at the very root of the reproductive organ.

As soon as the excitement weakens, the muscles begin to relax a little. Thanks to this, the accumulated blood flows freely. This process is accompanied by a decrease in the size of the penis to normal.

The head of the penis during erection is quite elastic and elastic. Due to this, the likelihood of injury to the penis and female genital organs during intercourse is reduced.

Violation of any of the functions of the penis indicates the presence of the disease. Such complaints are required to contact a urologist or andrologist.

Features of care and disease prevention

If a man does not comply with the norms of hygiene of the penis, the risks of developing diseases increase at times. The most common of them are phimosis or pathological narrowing of the foreskin, as well as balanitis or an inflammatory process in the head area. It is possible to prevent inflammatory and infectious processes in the groin area by observing the following rules:

  • shower with soap 1-2 times a day,
  • regular change of underwear,
  • Depilation or epilation of excess hair in the groin area,
  • wearing loose linen made from natural fabrics.

Experts advise men to also rinse the head area from smegma when moving the skin with the foreskin back to fully expose the head. To prevent diseases of the penis and head can also be protected by sexual intercourse with the use of barrier contraceptives, as well as the avoidance of accidental connections. For any alarming symptoms (redness, itching, burning), you should immediately contact a urologist.

Conclusion

The penis of a man consists of several departments, it is extremely important for a man to know the structural features of the head of the penis. It consists of the foreskin, frenulum, urethral opening, and also a large number of vessels and nerve endings are included in it. The head is needed to remove urine and sperm, to develop an erection during sexual stimulation, as well as to enjoy sexual intercourse.
