The Structure and Function of Penis Explained in Simple Terms

The penis is man’s external sex organ. It is used to have sexual relations, and blurt out the semen, and pass urine. It is the man’s counterpart to women’s clitoris. The word “penis” in Latin means “a tail.” Also in Latin, the word “penis” has almost the same meaning as the Latin verb “pendere”, which has the literal meaning of “to hang down.”

A man’s sexual organ is one of the wonders of nature. It is a receptor of pleasure that has inspired several myths about man with its intelligent design. The penis is delicate and protruding. Most of the time, it is long lasting and sensual.

The Penis Structure

  1. Glans . In most cases, the penis head is supple and shiny. Except during the sexual erection, the glans maintains as part of internal organ. During a sexual stimulation, the glans surfaces from prepuce. A glans’ surface is a mucous membrane similar to the internal part of any human lips. It is said that among men who have been circumcised, the glans is keratinized. This means, the penis is dry to touch, thick, and becomes insensitive.
  2. Frenulum . An elastic tissue, the frenulum joins the glan’s duodenal part and into the penis skin tube. In an arousal state, the frenulum becomes very sensitive that a constant light flicking is enough for them to reach their orgasm. After the arousal, the frenulum will pull back the prepuce skin into its original place, covering the penis.
  3. Interior Skin . Immediately after the corona is a region called the pink skin. It also comes out only during arousal, like the glans. The pink skin contains sebaceous glands emitting natural emollients helpful in warding off bacteria and in maintaining the tissue sensitive and soft.
  4. Skin Tube . The skin tube, which is folded, covers the primary penis shaft. Compared to the pink skin, the skin tube is not very sensitive. In circumcised men, the base section of the penis shaft has hair-covered skin that should have been found on pubic mound or the scrotum. The hairiness moves upward onto the penis shaft due to constant tension from arising from erections.
  5. Prepuce . A skin that covers the glans is called the prepuce. It is part of both the outer and inner skin. During circumcision, this prepuce, which is also termed the foreskin, is removed. It has specific nerve receptors, known as J-cells, which respond to straightening command.
  6. Tissues during Erection . Found inside the penis shaft are three separate chambers containing erectile tissues. During arousal, they are filled with blood. The erectile tissues are embedded down inside the body, which makes the penis longer by a score of inches more.
  7. Urethra . The man’s semen and urine both pass through and stay in a duct called urethra. It is located underneath the frenulum. This section is man’s homologue to a woman’s G-spot. Like in women, the urethra responds to the deep stimulating massage.

 Function of the Penis

There are two main function of a penis:

  • It acts as the passageway to emit the unnecessary human wastes like urine
  • It is the key organ in reproduction and therefore in procreation.
  • The penis is also a significant element in satisfying sexual urges, pleasure and of course, social wellness.

The penis has three main areas. Two of these are large chambers found on top, while the other is a smaller chamber found at the bottom. During erection, the penis engorges with blood, filling up all three chambers as well. The corpus spongiosum or the small chamber functions when a man urinates and emits semen. Corpora cavernosa or the larger chamber acts as the primary container storing the blood for the penis. Every time an erection occurs, the corpora cavernosa holds blood— as much as 90% -- in the penis.

Understanding Erection of the Penis

 During sexual arousal, the blood vessels are filled with blood, causing the penis to enlarge and become erect. It ejaculates when the semen is blurted out from it. Erection happens when the two chambers of corpora cavernosa are filled with blood. In sexual arousal, the arteries supplying blood into the penis widens increasing the blood flow. The Corpora cavernosa chambers will start filling up with more blood, causing the penis to stiffen. Then the penis contracts the veins that carry the blood away from the penis.

The Three Conditions Of Penis

 The following are the three states of the penis:

  • Flaccid penis . It is an unstimulated penis.
  • Flaccid Stretched Penis . It occurs when the penis at its flaccid state is stretched to its utmost distance.
  • A Full Erect Penis . It is when the penis reaches its maximum stimulation.

How Is the Penis Length Measured?

To measure the length, a penis should be at its erect state. Angling down towards the direction of the floor, measure the penis from the pubic bone—which is atop the penis base—into the tip.
