So you can better understand how penis enlargement works you should
understand the anatomy of the penis.

The above diagram clearly illustrates the corpora cavernosa chambers which
will be expanded with the use of natural enlargement programs and
penis pills.

corona: The 'crown,' a ridge of flesh demarcating where the
head of the penis and the shaft join.
corpa cavernosa: The corpora cavernosa are the two spongy
bodies oferectile tissue on either side of the penis which become
engorged with blood from arteries in the penis, thus causing
erection.
cowper's glands: The Cowper's glands secrete a small amount
ofpre-ejaculate fluid prior to orgasm. This fluid neutralizes the
acidity within the urethra itself.
ejaculatory ducts: The path through the seminal glands which semen
travels during ejaculation.
epididymis: The epididymis is a 'holding pen' where sperm
produced by the seminiferous tubules mature. The sperm wait here
until ejaculation or nocturnal emission.
foreskin, prepuce: A roll of skin which covers the head of
the penis in uncircumcised men.
frenulum, frenum: A thin strip of flesh on the underside of
the penis that connects the shaft to the head.
glans: The glans is clearly visible in illustration (A) as
the head of the penis. The glans in uncircumcised men is usually
covered by the prepuce. The glans is highly sensitive, as is the
corona, the ridge of flesh that connects the glans to the shaft of
the penis.
prostate gland: Also produces a fluid that makes up the semen.
The prostate gland also squeezes shut the urethral duct to the
bladder, thus preventing urine from mixing with the semen and
disturbing the pH balance required by sperm.
scrotum: The scrotum is a sac that hangs behind and below the
penis, and contains the testes, the male sexual glands. The
scrotum's primary function is to maintain the testes at
approximately 34 C, the temperature at which the testes most
effectively produce sperm.
seminal vesicles: The seminal vesicles produce semen, a fluid
that activates and protects the sperm after it has left the penis
during ejaculation
smemga: A substance with the texture of cheese secreted by
glands on each side of the frenulum in uncircumcised men.
testes, testicles: The male sexual glands, the two testes
within the scrotum produce sperm and testosterone. Within each
testis is a kilometer of ducts called the seminiferous tubules, the
organs which generate sperm. Each testicle produces nearly 150
million sperm every 24 hours.
urethra, meatus: The opening at the tip of the penis to allow
the passage of both urine and semen.
vas deferens: The ducts leading from the epididymis to the
seminal vesicles. These are the ducts that are cut during the
procedure known as vasectomy.
