Case Study- Semen analysis Flashcards
Evaluate the fol lowi ng semen analysis resu lts and answer the questions below.
Liquefaction: coagu lation did not occur
Color: white
Viscosity: watery
Volume: 5.0 ml
pH: 7.2
Concentration: no sperm seen
- Which tests on this semen yielded abnormal results?
- These results correlate with what diagnosis?
- What follow-up test should be performed and what is the
expected result?
- Which tests on this semen yielded abnormal results?
=> Liquefaction, viscosity, and concentration - These results correlate with what diagnosis?
=>Congenital absence of seminal vesicles and vas deferens. - What follow-up test should be performed and what is the expected result?
=>Fructose. Absent
The following semen ana lysis resu lts were obtained on a specimen that was collected at home in a condom and delivered to the laboratory 1 hour after collection. Liquefaction liquefied upon receipt
Color: white
Viscosity: viscous
Volume: 3.0 ml
pH 7.4
Concentration: 1 50 mill ion/ml
Motility: 10% prog ressive
1 0 % non prog ressive
80% nonmotile
Vi abil ity: 60% viable
- Explain how this specimen could be liquefied upon receipt in the laboratory.
- Explain the correlation between the low number of motile Sperms and the number of viable sperm.
- Discuss the reliability of these results in determining a state of infertility
- Explain how this specimen could be liquefied upon receipt in the laboratory.
=> Liquefaction normally occurs in less than 60 minutes - Explain the correlation between the low number of motile sperm and the number of viable sperm.
=>Sperm that are motile are viable. Sperm that are nonmotile may also be motile. Viable sperm may or may not be motile. The percent motile sperm cannot be higher than the percent of viable sperm, but the percent of viable sperm can be higher than the percent of motile sperm. - Discuss the reliability of these results in determining a state of infertility.
=> A count of 1 50 million sperm per milliliter is consistent with a fertile semen specimen. The motility is abnormally low which may indicate infertility. However, because the sample was collected in a condom, these results are NOT valid. The condom may have contained a spermicidal compound that will alter the motility and viability results. The semen analysis should be repeated on a
sample that is collected without the use of a condom and delivered to the laboratory in a timely fashion.
The fol lowi ng semen ana lysis resu lts were obta ined on a specimen that was collected at a fertility clinic.
Liquefaction : 15 minutes
Color: white
Viscosity: viscous
Volume: 1.0 ml
pH: 74
Concentration: 10 million/ml
Motil ity: 80% prog ressive
1 0 % non prog ressive
1 0 % nonmoti le
Viabil ity: 1 00% viable
Morphology: 80% normal
- Which tests on this semen yielded abnormal results?
- What may be an explanation for these abnormal results
with the remaining tests being normal? - If these are truly accurate results, how is this semen classified?
- Which tests on this semen yielded abnormal results?
=>Volume and concentration. - What may be an explanation for these abnormal results with the remaining tests being normal?
=>Incomplete collection may be responsible for the low volume and the decreased count. The highest concentration of sperm is usually found in the first part of the ejaculate. The sperm count could be low if the patient was sexually active within 3 days of this specimen collection. - If these are truly accurate results, how is this semen classified?
=> A semen with low sperm concentration that show
normal motility and morphology is classified as
oligozoospermic.
A semen speci men is submitted to the laboratory for postvasectomy eva l uation . The specimen is suspected to not be semen.
- Suggest testing that can confirm whether or not this specimen is semen
- Suggest testing that can confirm whether or not this specimen is semen
=>The presence of semen in a specimen can be verified by testing for acid phosphatase, prostate-specific antigen, and/or semenogelin.
