World Class Male Fertility Technology

Learn how Trak’s innovative microfluidic design provides the precision & reliability you need

Our proprietary microfluidic system is chemically engineered and manufactured to strict tolerances to provide the most precise sperm count measurement available.  As the Trak Prop spins, sperm are filtered through a lab-grade nanoparticle media in the tightly-defined Prop channels to ensure that your results are accurate to our stringent performance standards.


This breakthrough technology is the culmination of years of research & development dedicated to building, validating, and delivering clinical male infertility tests to your home.
