are many 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 corona, the ridge of flesh that connects the glans to the shaft
of the penis.

corona

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 Anatomy

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 deferns

The ducts leading from the epididymis to the seminal vesicles. These
are the ducts that are cut during the procedure known as vasectomy.
