Penis Anatomy
Penises come in many shapes, sizes, and colors. However,
the basic anatomy of the penis will usually be the same.
To better understand your penis and how it works, check
out our detailed penis anatomy below.

Explanation of Terms:
Corona: The 'crown,' a ridge of flesh demarcating
where the head of the penis and the shaft join.
Corpora cavernosa: The corpora cavernosa are the
two spongy bodies of erectile tissue on either side of the
penis which become engorged with blood from arteries in
the penis, thus causing erection. these are particular relevant
in natural enlargement because these areas can be increased
in size.
Cowper's glands: The Cowper's glands secrete a small
amount of pre-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 uncircumsized 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 the illustration
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 containts 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 uncircumsized
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. |
