SECTION I: Introduction
The SQA-V is a high performance analytical medical device that combines state-of-the-art
technology in electro-optics, computer algorithms and video microscopy. The system
performs a precise, 75-second semen analysis. The SQA-V runs a self-test and auto-
calibration on start-up and also runs external quality controls. The SQA-V incorporates
two systems: An automated system and a visualization system which allows
flexibility to analyze all types of semen samples.

WHO 5 Semen Parameters with SQA-V Abbreviation in Brackets
th
Light disturbances caused by moving sperm cells are detected and translated into
analog signal peaks.
The greater the number of motile sperm cells in the field of view, the higher the
peak.
The slower the sperm velocity the broader the signal peaks.
The average analog signal is mathematically proportional to MSC.
Sperm concentration is measured in the cuvette section of the SQA-V testing
capillary.
An infrared light wavelength specific to sperm cells is maximally absorbed by
sperm cells and minimally absorbed by other seminal fluid components.
In the final calculation of sperm concentration the SQA-V algorithm makes an
adjustment to account for the infrared light absorption of the seminal fluid
components.
