The Challenge
Our client, Genosis, had developed an off-the-shelf male fertility test which mimics nature by separating the motile (active) sperm from the non-motile (inactive) sperm, and then provides results using a chemical test.
The technology requires the sperm to travel through a column of fluid where it is imperative that the temperature is precisely held at normal body temperature, and with the additional requirement that the temperature regulation must be compatible with a disposable testing device.
The Approach
Plextek initially undertook a design study for Genosis which examined the potential options available for the fluid heating system, and specifically whether to use a simple discrete controller or a more flexible microcontroller derived solution.
After reviewing the options, the Plextek team developed an ultra-low cost but highly precise microcontroller-based system that could regulate the temperature of the fluid column to meet the Genesis requirements. The basic functions could then be easily augmented so that temperature limit checking and module health functions were incorporated at no additional material cost.

The Outcome
The hardware design, software design, and manufacturing engineering was undertaken in a way to minimise the test kit cost, and so ensuring that the final product would be both reliable and affordable.
After thorough laboratory testing and extensive clinical trials, the product was successfully launched as an off-the-shelf product containing both male and female fertility tests and sold through the Boots pharmacy chain.
The availability of an accurate and simple to use off-the-shelf screening test for male fertility affords couples earlier diagnosis which translates into a greater number of couples successfully conceiving and having healthy babies.
