In few paragraphs below, you will discover its detailed structure, what the average size is, many shocking facts, and even the way how an erection works!

Physiology & Structure of Human Penis

The length and girth of this body part may vary substantially between the mammals of different species. However, there is one common thing – the flaccid length is inferior to the size of erection.

Anyways, with regards to anatomy, there are 3 main parts to the human male reproductive organ:

  • The root – It begins at the caudal border of a pelvic ischial arch, which is the convergence of several pubic bones. The root is attached to the bulb of penis and lies inside of the perineal pouch.
  • The body – This is the part that extends from the root and makes up the shaft, skin, foreskin, and the prenuptial mucosa inside of your glans! The shaft is composed of 3 columns of tissues – corpora cavernosa on its dorsal sides and corpus spongiosum on its ventral side.
  • The glans – The glans – free end of the penis – is bulbous in shape. Its underside is called the frenulum, and its round base is called the corona. The perineal raphe is the line that runs along the bottom of this organ. On its tip is located the opening of a urethra (called meatus as well).

Pay attention: The human urethra is a tract that allows the release of urine or semen through the shaft. It passes through the prostate gland and is eventually joined by the ejaculatory duct!

What You Need to Know About Erection

The stimulation of this male organ into a point when it is prepared for sexual intercourse is referred to as erection. To achieve it, the following process takes place in your body:

  1. Blood vessels within your shaft go through significant dilation of arteries that supply blood.
  2. This causes your cock to become significantly engorged, stiffening it into a form that is ideal for the penetration!
  3. Engorged erectile tissue presses against the veins that carry your blood away, which constricts them and making them more visible on its surface.
  4. During erection, the skin upon your shaft is thinned out, which makes it more sensitive and renders it more susceptible to stimulation!

Pay attention: Some mammals have a great deal of erectile tissue in relation to the connective tissue; this is the reason horses’ penis has a greater ability to extend than bull’s.

  1. I feel fortunate – my boyfriend is around 7 inches. ~_~ So that means he’s somewhere close to the top end of this measurement thing. =P

  2. Talk about some interesting reading. I kind of want a bone inside my boner. That would be cool and open up a world of possibilities and maybe even a new career!

  3. Wait! An adult gorilla only has a 1.5 inch long schlong? That is hilarious! They seem like such tough and macho creatures.

  4. So the penis stops growing at age 17? That’s crazy! What happens when we get older, does it shrink at all or are we set with the same size for life?

  5. It’s interesting how an erection works and how the mind can completely shut that process down. Why is that possible? You would think that if we were supposed to procreate, we would be able to get stone-hard any time we wanted.
