Seminal Fluid Flashcards
(21 cards)
What two accessory glands are responsible for the the main composition of seminal fluid?
Seminal vesicles and prostate gland
What is the seminal vesicles responsible for?
70% of fluid ejaculate; responsible for fructose; prostaglandin present
What is the prostate gland responsible for?
25% of ejaculate volume; acidic microbinding, citric acid, and enzymes (acid phosphatase - exclusive).
Proteolytic enzymes (liquidification of seminal fluid); zinc
What is the main component of seminal fluid, which gives the ‘gray’ color?
Flavin
How long of sexual abstinence is require before collection?
2-7 days
At what temperature must seminal fluid be kept?
20-40 Celcius
How quickly should a seminal fluid sample be transported to the lab?
Within 1 hour
What would happen if only the initial part of the specimen is collected?
Sperm concentration falsely decreased; pH falsely increased
What would happen if only the final part of the specimen is collected?
Semen volume and pH falsely decreased; sperm concentration falsely increased
What would a brown/red semen sample indicate?
Presence of blood
What would a yellow color semen sample indicate?
Presence of certain drugs
How long does it take for seminal fluid to liquefy?
30 to 60 minutes
If a semen sample takes longer than 60 minutes to liquefy, what is this considered?
An abnormal sample
How would you describe a normal viscosity?
Free falling droplets after 60 minutes
How would you describe an abnormal viscosity?
Formation of string/threads >2cm in length
What is the normal volume of seminal fluid?
2-5 mL
What is reference range of pH?
7.2 - 7.8
A pH <7.2 indicates what?
Anatomical abnormalities
A pH >7.8 indicates what?
Infection
What would occur if you didn’t record the pH within one hour?
A false increase in pH due to loss of CO2.
What would occur if you recorded the pH after 1 hour of collection?
False decrease in pH because of accumulation of lactic acid (especially true with high sperm counts).
