Strict Criteria Sperm Morphology for Infertility Diagnosis and Treatment, Semen

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/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 WBCs are indicative of possible disorders in spermatogenesis and genital tract infection, respectively.(Wazzan W, Thomas A: Genital infection and male infertility.

Day(s) and Time(s) Test Performed Outlines the days and times the test is performed. This field reflects the day and time the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time required before the test is performed. Some tests are listed as continuously performed, which means assays are performed several times during the day.

Monday through Friday; 6:30 a.m. to 3:30 p.m.

Send specimen Monday through Thursday only and not the day before a holiday.

Analytic Time Defines the amount of time it takes the laboratory to setup and perform the test. This is defined in number of days. The shortest interval of time expressed is "same day/1 day," which means the results may be available the same day that the sample is received in the testing laboratory. One day means results are available 1 day after the sample is received in the laboratory.

2 days

Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Clinic Laboratories until the release of the test result

4 days

Specimen Retention Time Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded

Slides are stored for at least 6 months

Performing Laboratory Location Indicates the location of the laboratory that performs the test
