How The Trak Male Fertility Test Works

A new spin on male fertility testing that delivers more than just results. Trak’s patented precision-engineered technology uses centrifugal force to isolate and quantify sperm.


How Trak Works

The Trak System includes everything you need to test your sperm count and semen volume at home. No trips to the clinic. No mailing in your sample. No hassle. Testing is easy, immediate, and accurate.




Collect a sample into the Trak Semen Volume Cup and read your semen volume.



Load the sample into a test Prop and attach to the Engine.




After the 6-minute spin, read your sperm count results.

How To Read Trak Results

Accurate, Easy and Immediate
Trak is the only FDA cleared, at-home sperm test that measures sperm concentration into 3 categories: Low, Moderate, or Optimal for conception. The Trak result categories are based on World Health Organization guidelines and clinical studies that show having an Optimal sperm concentration statistically reduces the influence of other sperm parameters including motility and morphology on fertility outcomes.  To put it simply, the higher the count, the better your chances of conception.

In some cases, a low sperm count or semen volume can indicate more serious underlying health conditions in men like low testosterone, diabetes, or urological disorders. If a Trak user continuously tests low, it’s important that he make an appointment with a reproductive urologist.


Above 55 M/mL
Linked to faster pregnancy.

55 M/mL


Between 15 and 55 M/mL
May take longer to conceive.

15 M/mL


15 M/mL or below
May be at risk for infertility and should consult a physician.

According to the World Health Organization (WHO), men who regularly produce less than 1.5 milliliters of semen may be at risk for infertility, as low volume can inhibit the ability of sperm to reach the female reproductive tract. Low semen volume can also be associated with reduced sexual function and pleasure, low testosterone, and an increased risk of other urological conditions and chronic diseases.
