male fertility status
Sterile plastic container with plastic lid
Fresh semen specimen is required
Recommended 2-7 days abstinence (3-5 days is optimal)
Marshfield Campus: Call 24 Hour Services – Andrology section (ext 16377) to schedule collection
All other facilities: Prior to collection call 24 Hour Services – Andrology section (1-800-222-5835 ext. 16377 or 715-221-6377) to obtain a collection kit.
Buffer used to preserve semen for transport prohibits reporting the following results: pH, color, viscosity, liquefaction rate.
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.
