This proprietary technology is a 3D-printed fluidics chip that allows for a flow of buffer fluid across the collected sperm. Sperm are introduced at one end of the chip, then fluid flows into the chip, away from the collection point for the sperm. This causes the sperm to swim away from the starting point towards the collection point. Thus, the sperm that make it to the collection point are then collected and can be used in an assisted reproductive technology procedures like IVF. This method allows for the selection of the fittest sperm, which are defined as those that have the most forward motion away from the starting point, against the flow, to the collection point.
