Semen Analysis Flashcards
What are the four fractions in the semen that are contributed by the testes
epididymis, seminal vesicles, prostate gland, bulbourethral glands
Function for the secretion of sperm
seminiferous tubules
This contributes to the lower scrotum
temperature that is optimal for sperm development
external location of the scrotum
Function for the production of spermatozoa and are located in the epithelial cells of the seminiferous tubules
Germ cells
Provide support and nutrients for the germ cells as they undergo mitosis and meiosis (spermatogenesis)
Specialized Sertoli cells
Percent of the spermatozoa in the semen
5%
Percent of the seminal vesicle in the semen
60%
Percent of the bulbourethral glands in the semen
5%
Percent of the prostate fluid in the semen
20% to 30%
Semen is composed of
-Spermatozoa
-Seminal fluid
-Prostate fluid
-Bulbourethral gland
When spermatogenesis is complete, the immature sperm (nonmotile) enter the?
epididymis
Where does the sperm mature and develop a flagella?
epididymis
The entire process of sperm maturation takes approximately how many days?
90 days
They receive both the sperm from the
ductus deferens and fluid from the seminal vesicles
Ejaculatory ducts
They produce most of the fluid present in semen (60% to 70%)
seminal vesicles
The transport medium for the sperm and contains a high concentration of fructose and flavin
seminal vesicle fluid
Provides energy needed for
the flagella to propel them through the female reproductive tract
Fructose
Without this, sperm will not display motility in the semen analysis
Fructose
Responsible for the gray appearance of semen.
Flavin
Surrounds the upper urethra and aids in propelling the sperm through the urethra by contractions during ejaculation
muscular prostate gland
The muscular prostate gland is located at?
located just below the bladder
How many percent of the semen volume is acidic fluid?
Approximately 20% to 30%
Acidic fluid is produced by the?
prostate gland
The milky acidic fluid contains
high concentrations of?
acid phosphatase, citric acid, zinc
proteolytic enzymes
