SpermQT vs. Semen Analysis vs. Sperm DNA Fragmentation Testing

When a couple is trying to conceive, “male fertility testing” isn’t one test, it’s three different questions.

Standard semen analysis asks: are there enough sperm, and do they move correctly?

Sperm DNA fragmentation testing asks: is the sperm’s DNA physically damaged?

SpermQT asks: can this sperm actually function well enough to fertilize an egg and support a healthy pregnancy?

Each test measures something different, and knowing which question you’re asking matters for choosing the right next step.

  Standard Semen Analysis SpermQT Sperm DNA Fragmentation Testing
What it measures Sperm count, concentration, motility (movement), and morphology (shape) DNA methylation patterns across 1,200+ genes linked to sperm function The percentage of sperm with fragmented (broken) DNA strands
What it predicts Whether enough normally-shaped, moving sperm are present Whether sperm can find, bind, penetrate, and fertilize an egg — validated against real-world IUI outcomes The degree of DNA damage in a sperm sample
When it’s typically used First-line test for any couple starting a fertility workup Alongside or immediately after semen analysis, especially when semen analysis comes back “Normal” but the couple is still not pregnant Later in the fertility journey, often after recurrent pregnancy loss or failed IVF cycles
Evidence base Long-established WHO reference standard JARG (2026), F&S Science (2023), Frontiers in Genetics (2023) — peer-reviewed, including a 537-couple, 10-clinic real-world study Varies by method (e.g., SCSA, TUNEL, acridine orange staining)
Key finding A “Normal” result does not rule out subfertility Up to 25% of men with a “Normal” semen analysis have sperm incapable of producing a healthy pregnancy without advanced intervention (IVF/ICSI) High fragmentation is associated with pregnancy loss risk
Turnaround time Same day to a few days Approximately 2 weeks Approximately 7–10 days
Cost Often covered by insurance as a standard diagnostic $385 alone / $499 bundled with semen analysis (cash-pay) Approximately $400 (cash-pay)

The key differences, in plain terms

  • Standard semen analysis measures how sperm look and move, but does not measure whether they can function well enough to fertilize an egg.
  • SpermQT measures sperm function through DNA methylation analysis and is the only test with peer-reviewed evidence predicting real-world IUI outcomes.
  • Sperm DNA fragmentation testing measures DNA damage and is most commonly used for couples experiencing recurrent pregnancy loss.
  • SpermQT and DNA fragmentation testing measure fundamentally different things: DNA methylation patterns (function) vs. DNA strand breaks (damage).
  • SpermQT is designed to complement standard semen analysis, not replace it.
