Abstract
Cell sorting methods that improve sorting efficiency and productivity by elevating sorting pressures and incorporate certain steps to help the cells better survive such elevated pressures. In the case of sperm, sorting the steps of standardizing sperm samples, staining sperm samples in a single step, calibrating a flow cytometer to place sperm in the leading edge of droplets, and changing a catch fluid distance may be incorporated individually, or in combination to help sperm better survive the sex sorting process.
