About Trak

Trak Fertility, a brand under Sandstone Diagnostics, is a medical device company established in 2012 by Greg Sommer, Ulrich Schaff, and Sara Naab. The company's creation was driven by the observation that the burgeoning fertility industry was predominantly focused on women, leaving a significant market opportunity to address male reproductive health. Co-founders Greg Sommer, a PhD-level engineer, and Ulrich Schaff met at Sandia National Laboratories and identified the need for a solution that would allow men to proactively manage their fertility.

The company operates in the direct-to-consumer health tech market, providing a solution for men to monitor their reproductive health privately and conveniently. Its business model centers on the sale of the Trak Male Fertility Testing System, which includes a reusable engine and disposable test kits. Revenue is generated from the initial purchase of the system and subsequent sales of refill kits. The primary clients are men in committed relationships who are trying to conceive, though it also serves single men interested in monitoring their long-term fertility.

The core product is the Trak Male Fertility Testing System, an FDA-cleared device that enables at-home measurement of sperm concentration and semen volume. The system utilizes a proprietary mini-centrifuge, called the 'Engine', and single-use cartridges, or 'Props', to separate and quantify sperm cells in about six minutes. This technology provides a semi-quantitative result, classifying sperm count as "Low," "Moderate," or "Optimal" based on World Health Organization guidelines. A key differentiator from other at-home tests is its ability to provide a graded result rather than a simple binary positive or negative. The system also pairs with a mobile application that allows users to log results, access personalized health feedback, and track how lifestyle factors may be impacting their sperm count.
