The Basics of Human Penis Anatomy

The anatomy of the penis is complex. The penis is filled with blood under high pressure and a series of valves keep it in the penis to maintain the erection.

Blood it flows to the penis by two very small arteries that come from the aorta. These arteries have the same size like the arteries to your finger.

The main impotence cause is that the blood vessels become blocked and the blood can’t get to the penis.

Another major issue is a low pressure of blood from the penis into the veins around the penis called a venous leak, something similar to a hole in a tire. If the hole is large, you need to pump more air into the tire to keep it up!

To figure out how penis enlargement devices can help you, it is valuable to know penis anatomy and better understand how natural enlargement methods can change your manhood size.

Penis is the male sex organ used to copulate and to carry semen and urine away from the body. This organ is a pleasure receptor and is the analogue of the women’s clitoris.

Glans: 1 The head of the penis is usually shiny and supple. It is the greatly innervated and sensitive analogue to the female clitoris. The glans is basically an internal organ except in the time of sexual excitement, when it arises from the prepuce. The ridge where the glans connects with the shaft is known as the corona.

Frenulum: The frenulum is an elastic band of tissue joining the under (ventral) part of the glans to the skin tube. Frenulum helps contract the prepuce over the glans, over the glans, defending it from the drying effects of air and whatever your male organ can come into contact with.

Human Penis AnatomyInner Skin: Exactly beneath the corona is an area known as the pink skin or inner skin. The inner skin has sebaceous glands which excrete natural moisturizers. These fight bacteria and maintain the skin elastic and sensitive.

Skin Tube: The main shaft of the penis is wrapped by a folded tube of skin. This sector is not so sensitive as the inner skin.

Prepuce: The prepuce is the part of inner and outer skin that protects the glans. Also called the foreskin, this is what is eliminated in circumcision.

The edge of the prepuce where it folds back includes characteristic nerve receptors, often called J-cells that react when being straightened.

Erectile Tissue: Within the shaft are 3 chambers (Corpora Cavernosa and Corpus Spongiosum) of erectile tissue that fill up with blood at the time of stimulation. These are extended far within the body, hence the actual length is a a couple of inches more than what is seen outside.

Urethra 2 is the cylinder that passes on urine from the bladder and semen from the testes outside of the body.

The human male has an approximatively 8 inches long and opens at the end of the penis. The male urethra is devided in three parts:

Prostatic urethra crossing through the prostate gland. The prostatic urethra has three openings:

1. a small opening through which sperm coming from the vas deferens and ejaculatory ducts enters
2. the prostatic ducts which receive the fluid coming from the prostate
3. an opening for the prostatic utricle

Membranous urethra – about 1 or 2 cm long and the narrowest part of the urethra , located in the deep perineal pouch and passing through the external urethral sphincter

Spongy urethra (penile urethra) is located underneath the penis and it runs along its whole length. It measures about 15-16 cm in length and it travels through the corpus spongiosum. The penile urethra is the place where the ducts from the urethral gland enter.

The prostate gland is an exocrine gland (glands that secrete their products into ducts and not in the bloodstream), with the size of a large walnut, and its main function is to secrete and store 10-30% of the seminal fluid (one of the components of the semen). The smooth muscles in the prostate gland have a role in ejaculation.

The seminal vesicles are a pair of glands and their function is to secrete seminal fluid (about 70% of the total quantity of seminal fluid is produced in the seminal vesicles). The seminal liquid has a thick consistency and it is made of mucus, proteins, enzymes , vitamin C , fructose (the fructose is used by the spermatozoa as an energetic nutrient), flavins, phosphorylcholine and prostaglandins.

The vas deferens or ductus deferens are the two tubes that connect the left and the right epididymis (the tube that connects the efferent ducts to its vas deferens) to the ejaculatory ducts (the ejaculatory ducts trigger the ejaculation reflex) to move the semen. The vas deferens are surrounded by smooth muscle. The smooth muscle contracts reflexively during ejaculation and pushes the sperm forward. The sperm then passes through the ductus deferens, collecting fluids secreted by the male accessory sex glands on the way, and ends up in the urethra.

The testicles or testes are glands positioned outside the body , suspended by the spermatic cord and contained in the scrotum. The functions of the scrotum are the production of sperm and male sex hormones. The testicles are sensitive to injury of any kind.

The scrotum is the pouch the pouch made of skin and muscle that contains the testicles. The sperm is highly sensitive to temperatures over or below 94 degrees F and the scrotum helps keep the sperm at a constant temperature . This is achieved by the contractions and relaxations of muscles in the abdomen and of muscular tissue in the scrotum.

Penis Anatomy: Erectile Tissue

Your penis anatomy consists of 3 main parts, 2 large chambers on the top (Corpora Cavernosa) and 1 smaller chamber on the bottom (Corpus Spongiosum).

Each time you get an erection these 3 chambers fill with blood. The Corpus Spongiosum 3 is the chamber used primarily when you urinate and ejaculate. The corpus spongiosum is also considered to be erectile tissue though during the erection it does not increase in size as much as the corpora cavernosa and it has a normal blood flow during all the phases of erection.

Anatomy of the penisThe Corpora Cavernosa, on the other side, are the main blood retaining chamber of the penile. This is where 90% of all blood is placed each and each time that you get an erection.

Both the corpora cavernosa and corpus spongiosum are surrounded by a circular layer of elastic tissue. The elastic tissue is covered with a fine layer of skin. The skin on the penis is usually darker in color than the rest of the body and when the penis is flaccid it is free and plied. From the corona a circular fold of skin extends forward to cover the glans and it is called prepuce.

In non-pathological conditions the prepuce can be easily lifted to expose the glans. An interior fold of skin (the frenulum) goes over the inferior part of the glans and closing on it just below the opening of the urethra.

The limit your Corpora Cavernosa may fill with blood results in the size of your organ in erection. Therefore, using the penis extenders increases the tissue within the Corpora Cavernosa making it bigger when erect.

The base of the shaft has a key sensitivity and it seems to give pleasure as an indication of full penetration of the penile.

In plain words, the base tells the rest of the body that the organ is fully penetrated and this triggers pleasure in your whole body.

Your body goes through many transformations during sexual intercourse. Understanding these transformations helps us understand both our sexuality and that of our partner.

The testicles are more sensitive to light touch, particularly at the center, close to the perineum, and alongside the external edges, where they, where they touch the inner thighs. Most men do not like rough handling on testicles, but of course, that is subjective.

The perineum, particularly at the spot that meets the testicles can be also very sensitive, because of nerve that is close underneath the skin.

Penis Anatomy: Dictionary

corona: The “crown”, a part of skin tissue marking where the head of the penis and the shaft join.

corpora cavernosa: The corpora cavernosa are the two spongy bodies of erectile tissue which contain most of the blood in the penis causing erection.

cowper’s glands, bulbourethral gland: Secrete a small part of pre-ejaculate fluid before the orgasm. This fluid helps to lubricate the urethra for semen to pass through.

ejaculatory ducts: The two paths through the seminal glands which carries semen during ejaculation.

epididymis: A holding spot that provides the transport, storage, and maturation of sperm which leaves the testicles. The sperm wait here until ejaculation.

frenum, frenulum: An elastic band of tissue on the underside of the penis that connects the shaft to the head.

glans: Is the bulbous head of the penis. The glans at uncircumcised men is covered by the prepuce. The glans is extremely sensitive.

meatus, urethra: The opening tub at the head of the penis which allows the passage of both urine and semen.

prepuce, foreskin: A skin tissue which covers the head of the penis at uncircumcised men.

prostate gland: It produce, store and secrete the seminal fluid. Also the prostate gland prevents urine from mixing with the semen.

scrotum: Is an external sack (skin and muscle) containing the testicles, the male sexual glands. The function of the scrotum is to maintain the testicles around 34 C°, the temperature at which the testicles most effectively produce sperm.

seminal vesicles: Produce semen, a fluid that activates and protects the sperm after it has left the penis during ejaculation. 70% of the seminal fluid comes from the seminal vesicles.

smemga: Genital secretion, a substance secreted by glands on each side of the frenulum.

testes, testicles: The sexual glands, two of a kind, within the scrotum produce sperm and male hormones. Each testicle has a kilometer of ducts.

vas deferens: The tube that carries the sperm out of the testicles. These are the tubes that are cut during the vasectomy procedure.

We hope that reading the above content about penis anatomy was both interesting and informative for you, so you can better understand the whole process of penile enlargement.
