Frequently Asked Questions

What is the Trak Test?

Trak is an FDA-cleared diagnostic system for measuring sperm count in the comfort and privacy of home. No mailing in required – the Trak System includes an instrument (the Trak Engine), disposable cartridges (the Trak Props), and everything else you need for self-testing sperm count at home.  The free Trak Mobile App provides digital tools to help you log and understand your results and get personalized recommendations to take control of your reproductive health and improve your chances of conception

Do I really need to test my sperm count?

Trak is for any man interested in learning about and managing his reproductive health.  Sperm count is an important factor in a man’s fertility status as well as his general health.  Trak is intended to lower the bar for men to conveniently and routinely test this important (but under-appreciated) health parameter.

A recent study published in the journal Human Reproduction Update provides further evidence that men’s sperm counts are in deep, global decline. The research found that from 1973 to 2011, the average sperm count dropped 53% (a decline of 1.4% per year) from 99 to 47 M/mL with no indicators of stabilizing. This means the majority of men have a suboptimal sperm count and may take longer to conceive. With Trak you will see where you stand and learn how best to take control of your fertility.

Is the Trak Test Accurate?

Yes. Trak was demonstrated to be as accurate as a standard laboratory test. Our proprietary microfluidic system is engineered to provide the most precise sperm count measurement available.  As the Trak Prop spins, sperm are selectively filtered to ensure that your results are accurate to our stringent performance standards.

How many times do I need to test?

Trak comes with 4 tests and refill packs are available so that you can see changes over time. Your sperm count can change daily, weekly, and monthly due to changes in your health, lifestyle, and the world around you.  To get the most accurate benchmark results, we recommend testing twice to establish a baseline for measuring progress. After that, test at least monthly outside of your partner’s fertile window (the six-day interval when pregnancy can occur, ending on her ovulation day).  Many men start to see results starting after one month, but because it takes sperm a while to fully develop it may take two months or longer to see meaningful concentration changes after implementing health and lifestyle changes.

Has the Trak Test been evaluated by the U.S. Food and Drug Administration (FDA)?

Yes.  For your protection, the Food and Drug Administration (FDA) is responsible for ensuring that  products that can affect public health are safe and effective. Our Trak Male Fertility Testing System is an FDA Cleared medical device. Trak went through rigorous studies and examinations before being cleared for market to ensure our product is safe and effective to meet your fertility testing needs.

What does validated against gold standard lab method mean?

As part of the FDA clearance process, Trak was rigorously tested against the most accurate lab tests available to ensure that the system provides accurate results. In other words, the results you get with Trak really are as accurate as the lab.

Who built Trak?

Trak is designed and built by Sandstone Diagnostics in California’s Livermore Valley.

Founded in 2012 in part by scientists from Sandia National Laboratories, Sandstone’s mission is to provide high quality products that help people manage their health in new, innovative, and data-driven ways.

We are a team of scientists, engineers, software developers, and business professionals.  But more importantly we are fathers, mothers, brothers, sisters, and friends who care deeply about improving men’s reproductive health and helping people start their family.

Where can I buy Trak?

Trak is currently available for purchase through our secure website, on Amazon.com or through other participating online stores.  

I don’t want anyone to know I’m buying a sperm counter. Is this private?

We get it. Yes – all purchases go through our secure website and your Trak System will arrive in a plain, discreet box.

Is this covered by insurance? Can I use my FSA / HSA?

Trak is a perfect way to avoid letting your Flexible Spending Account (FSA) or Health Savings Account (HSA) dollars go to waste. At checkout, you can use the card associated with your flexible spending or health spending account to pay for the Trak Male Fertility Testing System and Refill Kits. If you’re unsure whether or not you have an FSA or HSA, please check with your employer or insurance company.

Do I need a prescription to use Trak?

Nope. Trak is a great way to start understanding your sperm health before your first doctor’s visit. Simply bring in your Trak results with you to get a jump start on your process. In addition, if you’re continually testing low with Trak, it can be a great indicator that further analysis from your doctor may be necessary.

What is Trak’s warranty and return policy?

Warranty -We warrant to the original purchaser that the Trak Engine will be free from material and workmanship defects under normal use for a period of one (1) year from the date of purchase from trakfertility.com or an authorized seller.  This warranty is non-transferrable.  If you submit a warranty claim before the end of the warranty period and your Engine verifiably fails the warranty, we will replace your Engine free of charge.

Please contact Customer Support at support@trakfertility.com or by phone at 1 (888) 241-2476  to initiate the return authorization for a defective Engine; Engines cannot be returned without prior authorization.

Return Policy – We are unable to accept returned product other than for the Engine replacement described in the Warranty section.

How long does this test take?

Trak is fast and easy. After you’ve collected your sample and loaded it into the Trak Prop (testing strip), the Trak Engine will spin for approximately 6 minutes to read your results. You should allow about 45 min to complete the test from start to finish.

Can I collect a sample during intercourse?

To ensure accuracy we recommend collecting your sample by masturbation only. Some consider this a nice feature.

Can I use lubricants to collect a sample?

Lubricants are not recommended.  Lubricants can be toxic to sperm cells and may interfere with the test accuracy.  For best results collect your sample without lubricants, and make sure you collect the entire sample.

What if I don’t collect the whole sample?

Your test results may be inaccurate if you were unable to collect the entire sample in the collection cup. Discard the collection cup and lid, and try to collect a sample again in 2 to 7 days with a new collection cup. It is important to collect an entire sample in the provided collection cups.

Can I reuse the droppers?

No. The droppers are designed to add a precise amount of sample to a Prop. If a dropper has been used it may not function correctly. Each test comes with a backup dropper if you need it.

Does it matter how much sample I add to a prop?

Yes. The included droppers are specially designed to dispense a precise amount of semen to a Prop. It is important to add one, and only one dropper load (one full length of the “stick” part of the dropper) of the sample into the Prop.

What should I do if my sample is too thick to fill the dropper after 30 minutes?

The included collection cups are specially treated with an enzyme (Chymotrypsin) to reduce the viscosity of the semen sample. Most samples will be thin enough to fill the dropper within 30 minutes after collection. If your sample is still too thick to fill the dropper, cap and swirl the cup again, and wait longer. Waiting up to 2 hours before starting the test is acceptable. If the sample remains too thick after 2 hours, discard the collection cup and sample, and test again in 2 to 7 days with a new collection cup. Drinking lots of water during the 24 hours before testing may help produce a more liquid sample.

How do I read my results? How were the categories defined?

Trak categorizes your sperm concentration as:

  • Optimal; Sperm concentration above 55M/mL
  • Moderate; Sperm concentration between 55M/mL and 15M/mL
  • Low; Sperm concentration below 15M/mL

Large population studies show, statistically, partners of men with higher sperm concentrations conceive faster.  When your sperm concentration is high enough (optimal), you’re likely to have enough quality sperm to overcome any abnormalities in other sperm parameters (e.g. poor motility or morphology) that may put you at higher risk for infertility. On the other end, men with a low sperm concentration are at a high risk for infertility and should see a physician. This is why we created a testing tool that lets you see where you stand across a range for concentration.

Other at home male fertility tests will give you only a “yes or no” result based on industry cut offs for fertility in men.. This is why we created a testing tool that  lets you see where you fall across the broad range of sperm concentrations to create a clearer comprehension around your ability to conceive. And only Trak lets you see changes over time as you work to improve your chances of conception.

Does a result above 55 M/mL mean we will get pregnant faster?

Not necessarily. In a study of 942 couples, sperm concentrations above 55 M/mL were on average tied to faster time to conception compared to sperm concentrations below that value.

Does a result above 15 M/mL indicate that I am fertile?

Not necessarily. Sperm concentration is an important indicator of male reproductive health, but there are other factors including sperm motility, sperm morphology, semen volume, semen viscosity, anti-sperm antibodies, genetic abnormalities, etc. You are advised to seek medical guidance if you and your partner have been trying to conceive unsuccessfully for 12 months or longer.

Can Trak be used to confirm a vasectomy?

Trak is not currently FDA-cleared for confirming vasectomy results or other contraception methods.

Can my medication affect the test results?

Possibly. Certain medications may affect sperm concentration or semen viscosity. Consult a physician for guidance.

What if I don’t see a white column in the prop?

If there is no white column when you run a test, run another test in 2 to 7 days. In the meantime, consider running a control test to ensure your Trak system is operating correctly. If there is no white column the second time you run a test, your sperm concentration is low and you are advised to consult a physician.

Where can I download the app?

The Trak: Sperm Health & Fertility mobile app is a free download available on Google Play, and the Apple App Store

My control test result does not look like the example in the Owner’s Guide.

If you conduct a test with the provided control solution but the control test result does not look like the expected result image, repeat the test with a new Prop, dropper, and sticker. An error may be caused by not shaking the control solution enough or loading less than a full dropper of control solution into the Prop.

If your control test result does not look like the expected result image a second time, do not use the Trak system and contact customer service.

The Engine stopped running and shows a blinking red light.

A blinking red light indicates an error (for example, the lid was opened before the test was complete) and the test result is not valid. Repeat the test with a new Prop, dropper, sticker, and any remaining sample in the collection cup.

The Engine shows a solid red light after completing a test.

When a test is complete, the Engine displays a solid green light for 3 minutes.  Be sure to read your Prop results within these 3 minutes for a valid result. If the Prop is left in the Engine for longer than three minutes, the red light will illuminate indicating that the result is now invalid and you will need to run another test with a new Prop, dropper, sticker, and any remaining sample in the collection cup.

There’s a slow blinking red light when I close the lid.

This means the Engine batteries are low.  Replace with two new AA alkaline batteries and try again.

There’s a single red light flash when I close the lid.

This means the Engine did not detect the Prop and won’t start. Try to push the Prop on more securely. If the Prop will not attach securely, you may need to start over with a new Prop, dropper, sticker, and any remaining sample in the collection cup.

There is no light when I close the Engine lid.

The Trak Engine will begin automatically and display a yellow light when you attach a Prop and close the lid.  If you don’t see a light it likely means that there aren’t any batteries in the Engine.
