Using the SQA-V and V-Sperm Visualization System

Tuesday, September 30, 2014


This demonstration video provides an overview on the use and function of the SQA-V / V-Sperm Visualization System. Used together, the system allows the user to view and record videos, take pictures of the semen sample, and accurately count using the system's slide adapter. Remember it ALL Started with a Sperm!

Semen Analysis in Urine | Retrograde Ejaculation

Monday, September 15, 2014
While the SQA-V does not have a specific mode for running retrograde ejaculation samples it is possible to run them using WASHED 20 MICRO mode a limited report of Motile Sperm Concentration, Progressive Motile Sperm Concentration, Velocity, and SMI.

For additional information on Retrograde Ejaculation, please find below a section of the WHO 5th ed. manual (p. 168) related to preparing Retrograde Ejaculation samples:

NEW SQA and QwikCheck Cleaning Instructions | Effective May 2014

Saturday, May 31, 2014
The SQA cleaning procedure has been updated for ease of maintenance and for system reliability. It was found that improper or excessive cleaning with more than one drop of cleaning fluid may impact the system over time. Please note that the new procedure differs from the previous version in the following three ways:

• Use of the 6” wooden electrostatic brush “long brush” is now STEP 1 and should be done DAILY.

• Use of the “blue dot cleaning paddle” is different, is STEP 2 and is performed WEEKLY (instead of daily)

• New cleaning kits will include the updated instructions and will have an outside label indicating a new kit.

Stabilized Sperm Proficiency Challenge for LOW LEVEL Target Values

Sunday, April 27, 2014



The need for external quality control schemes for confirming diagnostic procedures/equipment is of utmost importance. A number of multicentre studies on semen quality confirm this fact (1, 2). Quality control materials are best suited when they closely replicate the actual material being tested. However, due to the biological nature of semen, providing external quality control materials presents a challenge. Semen is motile for a relatively short period of time and the sample degenerates quickly. Semen samples prepared by proficiency/quality control organizations are based on adding a fixative media to the donor semen samples. As a result, the original nature of the fresh semen is distorted. In addition, there can be significant batch-to-batch variations in the proficiency challenge sample matrix. This causes problems running such samples in the SQA-V - especially at the low end of concentration.


Matrix and Spermatozoa Modification by Fixative Materials

Stabilized sperm is made from a fresh semen sample. This fixative process impacts the original semen sample as described below:


• The spermatozoa are shrunk because of fixation which causes a change to their size and shape.


• The seminal plasma is diluted with a fixative or completely replaced with a media causing a decrease in the sample viscosity. The SQA-V algorithm works based on the optical density of SEMINAL PLASMA (not the dilution media or modified “seminal plasma” used in stabilized sperm).


• A decrease in sample viscosity and density results in rapid cell sedimentation and uneven distribution of the cells throughout the volume of the sample. These factors may result in inconsistent concentration of cells in the samples received by the labs and in the aliquots taken for analysis. The sample tested may no longer reflect the target value established by the manufacturer.

All of these facts will adversely impact the accuracy of automated testing especially in low concentration samples because the prepared quality control material is not the same as a normal semen sample. The SQA-V is designed to run semen samples within one hour of collection and the concentration dynamic range of the SQA-V is 2 M/ml on the low end. Therefore, running a quality control sample of very low quality on the SQA-V, may result in a ZERO reading.


Running Low Level Stabilized Sperm Samples on the SQA-V GOLD System

If a stabilized sperm sample run on the SQA-V GOLD in the stabilized sperm Quality Control mode results in ZERO (beyond 2 M/ml dynamic range), re-run the sample in the Fresh mode as outlined below:

·        Turn on the SQA-V GOLD system and wait until auto-calibration/self-testing is completed.

·        Go to: MAIN MENU>TEST NEW PATIENT and enter:

o      PATIENT ID: Sample #

o      BIRTH DATE: Test date

·          From the next screen select:


o  WBC CONC: < 1 M/ml


·        Vortex the stabilized sperm sample.

·        Transfer the sample from the original vial to the 10-ml collection cup and mark it with the sample #.

·        Mix the sample thoroughly and immediately fill the SQA-V capillary and run the test.
