Systems for sorting sperm include a housing and a microfluidic system supported by the housing. The systems also include two or more inlets providing access to the microfluidic system to deliver sperm or semen and fluid to the microfluidic system, as well as an outlet for harvesting sorted sperm. The systems include a flow channel that provides a flow path for sperm from an inlet to an outlet while sperm travels against a fluid flow towards an outlet for harvesting. In the systems, fluid delivered to the microfluidic system via an inlet flows from the inlet towards one or more outlets, and the flow channel extending along the length of the microfluidic system provides a flow path for motile sperm to travel against the fluid flow towards a collection outlet for harvesting. In some embodiments of a system, the microfluidic system also includes a microporous filter arranged in the flow path between the inlet and the collection outlet to cause motile sperm traveling against the fluid flow to pass through the filter to reach the collection outlet for harvesting.

Systems and methods for sperm selection

A system and method for sorting sperm is provided. The system includes a housing and a microfluidic system supported by the housing. The system also includes an inlet providing access to the microfluidic system to deliver sperm to the microfluidic system and an outlet providing access to the microfluidic system to harvest sorted sperm from the microfluidic system. The microfluidic system provides a flow path for sperm from the inlet to the outlet and includes at least one channel extending from the inlet to the outlet to allow sperm delivered to the microfluidic system through the inlet to progress along the flow path toward the outlet. The microfluidic system also includes a filter including a first plurality of micropores arranged in the flow path between the inlet and the outlet to cause sperm traveling along the flow path to move against through the filter and gravity to reach the outlet.

System and method for sperm sorting

A video processing method improves the repeatability of point-of-care (POC) mean pixel intensity (MPI) analysis, for example by rejecting low-quality input data using image features. Using these features, the method selects high-quality frames and achieves an improvement in correlation and standard error for the MPI-absorbance relationship. In another example, a mobile device (e.g., smartphone) based image processing method produces an MPI output with smaller variances, lower limits of detection (LODs), and a higher dynamic range than existing methods. This method has improved performance in the presence of additive and multiplicative ambient light noise.
