Assessment of fructose levels is performed when
vitality is less than 75%.
motility is graded equal to or less than 2. sperm count exhibits azoospermia.
) liquefaction is less than 30 minutes.
sperm count exhibits azoospermia.
Semen specimens with a pH level less than 7.2 indicate
immunologic infertility.

excess level of fructose in the semen.
abnormalites of the epididymis.
All of the following can be associated with immunologic infertility except
immunoglobulin G coating sperm. antibodies from the female coating sperm.

increased presence of bacteria in semen.
All of the following orientations indicate the presence of sperm agglutinating antibodies except
• head/tail to mucous/cells.
•head to had.
) head to tail.
tail to tail.

Distinguishing between an increase in WBCs and an increase in immature spermatogenic cells in a semen sample is necessary in evaluating for all of the following conditions except
) infection in the genitourinary tract.
• contamination of a specimen during collection.
inflammation of the seminal vesicles or prostate.
) infertility hf the patient.
• contamination of a specimen during collection.

2. viral infections.
3. variance in periods of abstinence.
4. time of day of specimen collection.

A semen specimen for fertility studies from a 32-year-old male is delivered to the laboratory by the man’s wife within 1 hour of collection. She estimates her drive time as 20 minutes. The specimen was collected in a specimen cup provided by the laboratory and was kept at body temperature during the delivery period. The label of the specimen contains the patient’s name, the date, and the period of abstinence.
The technologist should
• receive the specimen and promptly deliver it to the UA department for analysis.
• reject the specimen and tell the wife the specimen must be recollected.
• place the specimen in the incubator until it can be tested.
check the specimen for liquidation and add 20 minutes.
reject the specimen and tell the wife the specimen must be recollected.
