Testes
Primary

reproductive organ
Sperm producing
organ.
Epididymis
Coiled
Tubules
Seminiferous Tubules 
Epididymis  Vas
Deferens
Vas Deferens
Tube
that connects:
Epididymis  Vas Deferens
 Urethra
 What
happens with a vasectomy?
 A vasectomy can be performed under local
anaesthetic. During a vasectomy, the
scrotum is cut on both sides and the vas
deferens drawn out. The exact surgical
procedure varies slightly but usually
involves the vas deferens being cut and a
small piece removed, with the ends being
tied and /or sealed using heat.
Ejaculatory Duct
Where
sperm enters the
urethra.
Where Vas Deferens and
duct of the Seminal Vesicles
combine
Urethra
Tube
leaving the body:
Bladder  Outside

Case report
 A 66-year-old white man presented to a local
emergency department with fever and severe
dysuria. He was admitted for antibiotic treatment
of urosepsis. CT was performed and identified a
tubular metallic object in the patient’s urethra.
After discharge from the hospital, the patient
was referred for definitive urologic evaluation of
this finding.
Penis
Cylindrical
Organ to

through the urethra.
Prepus (Prepuce)
Covering

(Foreskin)
Circumcision
Removal
of the prepuce.

Gland Approximate % Description

testes 2-5%[1] Approximately 200- to 500-million
spermatozoa (also called sperm or spermatozoans), produced
in the testes, are released per ejaculation.

seminal vesicle 65-75% amino acids, citrate, enzymes,
flavins, fructose (the main energy source of sperm cells, which
rely entirely on sugars from the seminal plasma for energy),
phosphorylcholine, prostaglandins (involved in suppressing an
immune response by the female against the foreign semen),
proteins, vitamin C

prostate 25-30% acid phosphatase, citric acid, fibrinolysin,
prostate specific antigen, proteolytic enzymes, zinc

bulbourethral glands < 1% galactose, mucus (serve to
increase the mobility of sperm cells in the vagina and cervix by
creating a less viscous channel for the sperm cells to swim
through
Seminal Vesicle
Connect
to the vas deferens
and release
 Fructose
 Prostaglandins
•Suppress and help
female contractions
Prostate Gland
 Chestnut
shaped gland posterior to the
bladder.
 Produces a milky buffer that empties into
the urethra.

Bulbourthral Gland
 “Cowper’s
Gland”
 When stimulated, secrete natural lubricant
to aide in intercourse.
