Anatomy of the Penis

The anatomy of the penis is made up primarily of tissues which are very spongy and this is why it is possible to be either erect or flaccid. The penis has three separate cylinders, two of which are paired together and makes up the greater part of the penis, called the corpora cavernosa, which is the area that becomes engorged with blood when the penis becomes hard. The third cylinder, the urethra, is on the side facing the ground and it is the tube through which the urine and semen pass. The head of the penis, or the glans contains the urethral opening at the tip of the penis (the hole).

Men are born with a loose covering of skin over the glans, called the foreskin, but a good number of men have this skin surgically removed when they are infants. Some opt to have this done when they are fully grown as well, for cosmetic or religious reasons.

Proper functioning of the penis and associated organs, like all other bodily organs, relies on a wide variety of vitamins, minerals, and other nutrients.  Below is a diagram showing the anatomy of the penis in great detail.
