Customer Stories

IT’S Storytime

Trak was a game changer.
It gave me the motivation I needed to get my health on Trak”.

Jay and Toni had been struggling to conceive for just under 12 months when they decided to purchase Trak. The first test was a little disappointing to realize that Jay’s sperm count was a little lower than it should be, but it gave them hope that there was something they could do.

After filling out the health assessment in the app, Jay realized there were a number of changes he could make in his life that would improve his health and hopefully, his sperm count.

After two months of trading chips for bell peppers, Jay was pumped to learn that his sperm count was “Optimal.” A month later, Toni surprised him with a positive pregnancy test result!

More Customer Stories

“I was undergoing fertility treatment (varicocele surgery and later IVF) and found myself needing multiple expensive semen analyses ($200+ a pop in my area). Trak gave me a cheap way to supplement the clinical information in between lab tests and roughly monitor my post-procedure progress.”

“I’ll never forget having to wait to go into the ‘sample room’ with my husband with the nurse coming out every 15 minutes saying ‘So sorry, our previous client is not done yet’. And then there was the poor man that walked out of there after nearly 45 minutes of trying to perform under pressure!  When I learned of Trak, I kept thinking of that poor man and how he could have skipped all that and used Trak. I’ve since heard similar stories from other wives about their poor husbands. Here’s to Trak! Eliminating performance anxiety and allowing real tracking of a real fertility issue!”

“I work in the fertility industry and heard about Trak via a colleague. I found the test to be useful and it helped me be confident going into the conception phase. We were successful and are expecting a daughter in December.”

Our team of experts created a program specifically designed to help you navigate through all your male fertility questions so you can reach your reproductive goals.

Trak is accelerating the field by merging highly precise home testing with digital data tools: an unprecedented approach to a better understanding of men’s reproductive health.

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.

OPTIMAL

Above 55 M/mL
Linked to faster pregnancy.

55 M/mL

MODERATE

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

15 M/mL

LOW

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.
