Penis Anatomy: The Complete Structure of The Penis

This post will help you in understanding how the penis is structured using the proper medical terms.

In order to understand how the enlargement process will affect your organ, it is helpful to know the structure of your member and how it works.

As you can see in the picture to the left, there are two main chambers in the organ, the corpora cavernosa.

During arousal, these chambers are filled with blood, which will create an erection.

When these chambers expand, it puts pressure on the tunica albuginea and the blood gets trapped in the corpora cavernosa, as a result, the penis becomes erect.

The corpus spongiosum is filled with blood in lesser extent as compared to corpora cavernosa.

This protects the fragile tissues of the urethra.

The important factor that determines the size of an erect penis is the capacity of the corpora cavernosa.

The penis will only become as large as the chambers allow.

Most of male enlargement methods aim at increasing the capacity of these chambers, by allowing more blood into the male organ during an erection.

  • The Crown or Corona : The corona is a ridge of flesh that separates the head of the penis and joining of the shaft.
  • Corpa Cavernosa : These are two spongy bodies that are present in the erectile tissue on both sides of the schlong which become enlarged when blood from the arteries flows into the penis, thus leading to an erection.
  • Corpus Spongiosum: It is a spongy tissue that surrounds urethra. This tissue expands to protect the urethra when the chambers are filled with blood, but to a lesser extent as compared to the corpora cavernosa.
  • Cowper’s Glands: Prior to orgasm a very small amount of fluid comes out of this cowper’s glands. This fluid helps in neutralizing the acidity inside the urethra.
  • Dorsal Side: The upperside of the penis is called the dorsal side.
  • Ejaculatory Glands: The duct which semen passes through during the process of ejaculation.
  • Epididymis: The task of the epididymis is to act as a ‘holding of pen’ where sperm is produced by the seminiferous tubules mature. The sperm wait untill ejaculation or nocturnal emission happens.
  • Foreskin, Prepuce: It is a roll of skin which hides the head of the member in uncircumcised men.
  • Frenulum, Frenum: It is a thin strip of flesh on the lowerside of the member that connects the shaft to its head.
  • Glans: The glans is seen in the illustration as the head of the penis. The glans in uncircumcised men is usually hidden by the prepuce. This glans is highly sensitive, as is the corona, the ridge of flesh that joins the glans to the penis shaft
  • Head: The bulbous tip that is present in the penis is also known as glans.
  • Meatus: The hole present at the tip of the dick that allows both the passage of urine and semen.
  • Perineum: The area present between both the scrotum and anus.
  • Prostate Gland: It produces a fluid that helps in formation of semen. The prostate gland also helps in squeezing the urethral duct to the bladder, which prevents urine from mixing with the semen and thus disturbing the pH balance required for development of sperm.
  • Pubococcygeus Muscle: It is also known as the PC or pelvic floor muscle, which is necessary to control urination and ejaculation.
  • Raphe: The ridge is seen running from the meatus to the perineum across the scrotum that is formed during the development of fetus and gender assignation.
  • Scrotum Is A Sac : The sac that hangs behind and below the penis is scrotum, and contains the testes, which are the male sexual glands. The primary function of the scrotum is to maintain the testes at approximately 34 C, at this temperature the testes most effectively produce sperm.
  • Semen: The fluid produced during the ejaculation is made up of 2-5% sperm. The main component of semen is seminal plasma, with large concentrations of Zinc, and amines that protect the sperm from the acidic environment present in the vagina.
  • Seminal Vesicles: A fluid that activates and protects the sperm after it has left the cock during ejaculation is produced by the seminal vesicles.
  • Shaft: The main portion of the member consists of the corpora cavernosa, corpus spongisum, urethra, cavernosal artery and dorsal vein and artery.
  • Smegma: This a substance with the texture of cheese made up from oils secreted from glands present on both side of the frenulum, that combined with skin cells, and moisture. This mostly occurs in uncircumcised men.
  • Testes, testicles: The male sexual glands, the two testes within the scrotum produce sperm and testosterone. Within each of the testis there is a kilometer of ducts called the seminiferous tubules; this is the organs that produce sperm. Each testicle produces nearly about 150 million sperm in 24 hours.
  • Urethra: The passage of the penis that carries urine from the bladder and semen from the testes to the end of the head.
  • Vas Deferens: The ducts which leads from the epididymis to the seminal vesicles. These are the glands that are dissected during the procedure known as vasectomy.
  • Ventral Side: The Lower side of the penis.
