External Organs
The penis and scrotum are the external sexual organs of men.
Vocabulary of the penis and scrotum
glans: The glans is 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.
Corona: The 'crown,' a ridge of flesh demarcating where the head of the penis and the shaft join.
frenulum, frenum: A thin strip of flesh on the underside of the penis that connects the shaft to the head.
foreskin, prepuce: A roll of skin which covers the head of the penis in uncircumsized men.
urethra, meatus: The opening at the tip of the penis to allow the passage of both urine and semen.
smemga: A substance with the texture of cheese secreted by glands on each side of the frenulum in uncircumsized men.
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.
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.
