Structure and Fxn of the Male
Accessory Reproductive Glands
(seminal vesicles, prostate gland,
and bulbourethral gland)
MT: Male Reproductive System
Structure of Seminal Vesicles
coiled pouches
 lie along the lower part of the posterior
surface of the bladder
 are directly in front of the rectum
 how well it functions depends on the
amount of testosterone

Fxn of Seminal Vesicles

secrete an alkaline, viscous liquid (rich in
fructose) that makes up part of the semen
Structure of Prostate Gland
gland that lies below the bladder
 shaped like a donut with the urethra going
through the center of the donut
 Enlarged prostate constricts urine flow

Fxn of Prostate Gland
Secretes a thin alkaline substance that
makes up 31% of semen
 Alkalinity helps protect the sperm from acid
in the urethra and vagina

Structure of Bulbourethral Gland
AKA Cowper’s Gland
 small round gland resembling a pea
 located below the prostate

Fxn of Bulbourethral Gland
Secretes mucous to lubricate the urethra
 Secretes alkaline fluid to protect sperm

Prostate Cancer
32,000 men die/year
 If large enough, tumor can be felt through
rectal exam
 Early detection is best
 Screening is most effective with rectal exam
and a blood test looking for PSA (prostate
specific antigen)
