questions about the penis on alt.sex, and this FAQ will attempt to begin to
answer some of them.
Vocabulary of the penis and scrotum
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.

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.
Male
Internal Sexual Organs
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.
Epididymis
The epididymis is a 'holding
pen' where sperm produced by the seminiferous tubules mature. The sperm wait
here until ejaculation or nocturnal emission.
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.
Seminal vesicles
The seminal vesicles produce semen,
a fluid that activates and protects the sperm after it has left the penis during
ejaculation.
The 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.
Corpa 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.
Ejaculatory Ducts
The path through the seminal
glands which semen travels during ejaculation.
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.
