Different application or purposes of seminal fluid analysis
Different component of semen
known as matured cells
spermatozoa
Nutritive medium of proper osmolality and volume
Seminal Plasma
Activates the spermatozoa to greater motility
Seminal plasma
5% of the semen volume come from
testis (seminiferous tubules)
Seminiferous tubules is located at
testis
for maturation and storage of sperm cells
Epididymis
60% of the semen volume come from
Seminal vesicle
viscid, neutral, or slightly alkaline fluid , often yellow (flavin)
Seminal vesicle
high in fructose
Seminal vesicle
seminal vesicle provides substrate responsible for the
coagulation
seminal vesicle provides substrate responsible for the coagulation of semen following
ejaculation
prostate provides
20-30%
relatively slight amount
first fraction
clearly viscid fluid believed to originate largely or perhaps exclusively from the urethral and bulbourethral glands
first fraction
cleanses and lubricates
first fraction
prostatic secretion along with most of the spermatozoa
Second fraction
relatively small secretions from the epididymis & vasa deferentia
Second fraction
consist almost entirely of a muscoid secretion resulting from emptying of the seminal vesicles
Third fraction
Complete Collection is Essential
Collection of Seminal Fluid
Methods of Collection
seminal fluid analysis, gross examination
Odor must
musty , acrid, fishy
