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

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.
