ORDER QUESTIONS AND ANSWERS
| Question ID | Description | Answers |
|---|---|---|
| OSSC1 | Sperm Count/mL(x10(6), XX.X) |
Specimen Required
Defines the optimal specimen required to perform the test and the preferred volume to complete testing
Patient Preparation: Patient should have 2 to 7 days of sexual abstinence at the time of semen collection for accurate results.
Container/Tube: Slides
Specimen Volume: 2 slides-10 microL of liquefied semen on each slide
Collection Instructions:
1. If sperm concentration is <10 million/mL, centrifuge the specimen at 300 x G for 10 minutes before making slides.
2 Label 2 frosted slides in pencil with the patient's first and last name and the date of specimen collection. No adhesive labels.
3. Allow the semen to liquefy for 30 minutes.
4. Place 10 mcL of liquefied semen on the label end of each slide, and evenly smear the specimen using a plain slide (this process is the same as making a blood smear).
5. Allow the smears to air dry for 15 minutes before placing both slides into 1 slide holder for shipment.
Specimen Minimum Volume
Defines the amount of sample necessary to provide a clinically relevant result as determined by the testing laboratory. The minimum volume is sufficient for one attempt at testing.
A minimum count of sperm is needed; lab will determine

Clinical Information
Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test
Infertility affects 1 out of 6 couples of child-bearing age. Approximately 40% of infertility cases have a female-factor cause and 40% have a male-factor cause. The remaining 20% of infertility is due to a combination of male- and female-factor disorders or is unexplained.
Abnormalities in sperm morphology are related to defects in sperm transport, sperm capacitation, the acrosome reaction, binding and penetration of the zona pellucida, and fusion with the oocyte vitelline membrane. All of these steps are essential to normal fertility.
Strict criteria sperm morphology testing greatly assists with selecting the most cost-effective in vitro sperm processing and insemination treatment for the couple's in vitro fertilization (IVF) cycle. Sperm with severe head abnormalities are unlikely to bind to the zona pellucida. These patients may require intracytoplasmic sperm injection in association with their IVF cycle to ensure optimal levels of fertilization are achieved. This, in turn, provides the patient with the best chance of pregnancy.
Reference Values
Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.
Normal forms: > or =4.0%
Germinal cells/mL
<4 x 10(6) (normal)
> or =4 x 10(6) (elevated germinal cells in semen are of unknown clinical significance)
WBC/mL
<1 x 10(6) (normal)
> or =1 x 10(6) (elevated white blood cells in semen are of questionable clinical significance)
Interpretation
Provides information to assist in interpretation of the test results
Categorizing sperm according to strict criteria based on measurements of head and tail sizes and shapes. Sperm with abnormalities in head, tail size, or shape may not be capable of completing critical steps in sperm transport and fertilization.
Cautions
Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances
No significant cautionary statements.

Method Description
Describes how the test is performed and provides a method-specific reference
Sperm is categorized according to strict criteria based on measurements of head and tail sizes and shapes. Sperm with abnormalities in head, tail size, or shape are not capable of completing steps in the sperm transport and fertilization process. Quantification of the germinal and white blood cell (WBC) content in semen is performed because the presence of germinal and WBC are indicative of possible disorders in spermatogenesis and genital tract infection, respectively. The information collected will help determine the most cost-effective therapy for treating male-factor infertility. (Wazzan W, Thomas A: Genital infection and male infertility.

Day(s) Performed
Outlines the days the test is performed. This field reflects the day that the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time before the test is performed. Some tests are listed as continuously performed, which means that assays are performed multiple times during the day.
Monday through Friday
Report Available
The interval of time (receipt of sample at Mayo Clinic Laboratories to results available) taking into account standard setup days and weekends. The first day is the time that it typically takes for a result to be available. The last day is the time it might take, accounting for any necessary repeated testing.
Specimen Retention Time
Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded
Performing Laboratory Location
Indicates the location of the laboratory that performs the test
