Determining male fertility status
This test should NOT be used to check for sterility following vasectomy procedure. In such cases, order PVSEM (if within 12 months of vasectomy) or SEM-QL (if more than 12 months after vasectomy).
Sterile plastic container with plastic lid
Fresh semen specimen is required
Recommended 2-7 days abstinence (3-5 days is optimal)
Marshfield Campus: Provider's MA to enter order/appointment in Central Lab M-F between 8:00 a.m. and 3:00 p.m. (excluding holidays/observed holidays) and then notify 24 Hour Services - Andrology section (ext 16377) of collection date and time.
All other facilities: Provider's MA call respective lab to schedule collection. Collection kit will be handled by regional lab and sent to Marshfield for analysis.
Preserved samples not received in Marshfield within 24 hours
If site unable to perform pH and viscosity prior to adding transport buffer, these results will not be reported.
Note: In-house study indicates 80-90% of sperm motility is retained when transport buffer is used, meaning preserved samples demonstrating 32% to 39% motility may be in the normal range if analysis was performed on a fresh (unpreserved) sample. If indicated, it is recommended that borderline patients collect a fresh sample at Marshfield Main Campus to verify fertility status.
Semen composition can vary widely in the same man from specimen to specimen. Semen parameters falling outside normal ranges do not exclude fertility. Analysis of 2-3 semen samples is recommended to establishing patient's fertility status.
