SemenOrdering Guidance
This test should not be used to check patient's sterility following a vasectomy. For such cases, order POSV / Post Vasectomy Check, Semen.
Semen analysis specimens submitted to Mayo Clinic Laboratories are not acceptable for fructose testing due to the use of dilution media. For specimen requirements for fructose testing in azoospermia patients, see FROS2 / Fructose, Qualitative, Semen.
Submit separate specimen to rule-out ejaculatory duct blockage. Positive result indicates no blockage.
Shipping Instructions
Specimen must arrive within 24 hours of collection. Send specimen Monday through Thursday only and not the day before a holiday. If holiday falls on a Saturday, holiday will be observed on the preceding Friday. Sunday holidays are observed on the following Monday. Specimen should be collected and packaged as close to shipping time as possible. Laboratory does not perform testing on weekends.
Necessary Information
Include the following information:
-Semen volume (required)
-Viscosity
-pH
-Appearance (color)
-Number of days of sexual abstinence
Specimen Required
Patient Preparation: Patient should have 2 to 7 days of sexual abstinence at the time of semen collection for accurate results.
Supplies: Semen Analysis Kit - Dilution Media (T178)
Specimen Volume: Total ejaculate
Collection Instructions:
See Semen Collection Specimen Preparation and Packaging Instructions included with the kit
1. Prior to use, allow dilution medium to warm to room temperature for 45 to 60 minutes.
2. Allow semen to liquefy at room temperature for up to 30 minutes.
3. Use sterile volumetric pipet or tube for volume measurement.
4. Pour liquefied semen into 50-mL dilution medium container within 60 minutes of semen collection time, cap tightly, but do not overtighten, and gently mix.
Note: Proper temperature maintenance of specimen throughout processing and shipping is critical. All materials the specimen is exposed to should be at room temperature (20–28° C).

All specimens will be evaluated at Mayo Clinic Laboratories for test suitability.Reference Values
SEMEN ANALYSIS
Appearance: normal
Volume: ≥1.5 mL
pH: ≥7.2
Motile/mL: ≥6.0 x 10(6)
Sperm/mL: ≥15.0 x 10(6)
Motility: ≥40%
Grade: ≥2.5
Note: Multiple laboratory studies have indicated that semen parameters for motility and grade on average retain 80% of original parameters when our shipping method is used for transport. Using these averages, samples with 32% to 39% motility and grade of 2 may be in the normal range if testing was performed shortly after collection. Therefore, these borderline patients may need to collect another sample at a local fertility center to verify fertility status.
Motile/ejaculate: ≥9.0 x 10(6)
Viscosity: ≥3.0
Agglutination: ≥3.0
Supravital: ≥58% live
Fructose: positive
Note: Fructose testing cannot be performed on semen analysis specimens shipped through Mayo Clinic Laboratories. If patient is azoospermic, refer to FROS2 / Fructose, Qualitative, Semen. Submit separate specimen to rule-out ejaculatory duct blockage. Positive result indicates no blockage.
STRICT MORPHOLOGY
Normal forms: ≥4.0% normal oval sperm heads
Germ cells: <4 x 10(6) (normal)
≥4 x 10(6)/mL (elevated germinal cells in semen are of unknown clinical significance)
White blood cell count:
<1 x 10(6) (normal)
≥1 x 10(6)/mL (elevated white blood cells in semen are of questionable clinical significance)
Method Description
Semen Analysis:
The sample is measured for volume and analyzed microscopically to determine the number of sperm present, the number of moving or motile sperm, and the properties of the sperm motility.(WHO laboratory manual for the examination and processing of human semen. 6th ed. World Health Organization; 2021)
Strict Morphology:
Sperm is categorized according to strict criteria based on measurements of head and tail sizes and shapes. Sperm with abnormalities in head/tail size/shape are not capable of completing steps in the sperm transport and fertilization process. Quantification of germinal and white blood cells (WBC) in semen is performed because the presence of germinal and WBC may indicate disorders in spermatogenesis and genital tract inflammation, respectively. The information collected will help to determine the most cost-effective therapy for treating male-factor infertility.(Wazzan W, Thomas A: Genital infection and male infertility. AFS Annual Meeting, Postgraduate course, 1990; Menkveld R, Oettle E, Kruger T, et al: Atlas of Human Sperm Morphology. Williams and Wilkins, 1991; Scoring is based on a modified method of WHO laboratory manual for the examination and processing of human semen. 6th ed. World Health Organization; 2021)
