What is Penis ?
Penis is the organ of the male reproductive system through which
semen passes out of the body during sexual intercourse. The penis is
also an organ of urination. The Penis is the male organ of
copulation and of urinary excretion, formed by three columns of
erectile tissue, two arranged laterally on the dorsum and one medianly below; the extremity is formed by an expansion of the
corpus spongiosum, covered by a free fold of skin.
Penis Anatomy
The head of the penis (glans) has a covering, called the foreskin
(prepuce). This covering folds in on itself, forming a double layer.
The foreskin is not a `flap' of skin on the end of the penis, and it
is not `useless' or `redundant' skin. There is some natural
variation in the length of the foreskin, which often covers a bit
more or less of the glans than illustrated. In an average
circumcised adult man, the area of skin that is missing because of
penile reduction surgery would, when erect and unfolded, measure
approximately three by five inches, or a little smaller than a
postcard. That is about half the total skin of the penis.
The anatomy of the penis is complex. It is comprised primarily of
two cylinders of sponge-like vascular tissue that fill with blood to
create an erection. Blood is pumped into the penis under great
pressure and a series of valves keep it in the penis to maintain the
erection. A third cylinder is the urethra, a tube that carries the
urine and the ejaculate. The knobby head of the penis is called the
glans.
