SwimCount is the only at-home male fertility test that measures progressive motility, making it the best predictor of determining a man’s fertility potential available over-the-counter.

The semen sample is loaded into the SwimCount Sperm Quality Test device. Inside the device, only PMSCs can swim through the filter and into a swim-up compartment. In the swim-up compartment, the PMSCs are stained. The more PMSCs, the darker the test result. The assay inside of the device stains mitochondria of the PMSCs where the color is changed (only in living cells) by an enzyme.
