Does Sperm DNA Fragmentation Actually Matter? Here's What the Research Shows Part 2 of the SwimScore Fertility Series: DNA Fragmentation If progressive motility is the metric most men have heard of, DNA fragmentation is the...
Progressive motility is one of the most important and most improvable parameters in male fertility. The research consistently identifies it as a meaningful predictor of natural conception. The evidence that carnitine and CoQ10 improve it is consistent and credible. Whether that improvement translates directly to better pregnancy odds isn't fully established yet.
The Research Behind SwimScore: What the Science Says About Male Fertility Testing Male fertility testing has changed significantly over the past decade. What once required a clinic visit and a weeks-long wait can now be...
What Is a CLIA-Certified Lab and Why Does It Matter for semen Testing? When men research at-home fertility testing, they encounter the term CLIA-certified lab fairly quickly. It appears on the packaging of mail-in tests,...
SwimScore and SwimCount are two male fertility products with similar names that get regularly confused. Both involve collecting a sperm sample at home. Beyond that, they work differently, measure different things, and are built for different purposes. SwimScore processes samples in a CLIA-certified laboratory — the same federal standard required of hospital and fertility clinic labs. CLIA certification covers accuracy requirements, quality controls, and regular proficiency testing. SwimCount is a self-contained device you interpret yourself. There is no lab involved, which is part of what makes it fast and accessible. For a quick directional read on motile sperm count, that is perfectly reasonable. For men making decisions about fertility treatment or trying to understand a clinical picture, lab-grade analysis adds a level of reliability that matters.
Intermittent fasting is everywhere. The 16:8 method — 16 hours fasting, 8 hours eating — has become a default health protocol for men who train, want to lose fat, or simply prefer skipping breakfast. But if fertility is on your radar, there's a more complicated story underneath the hype. Here's what the research actually says about time-restricted eating (TRE), testosterone, and sperm.
Getting a semen analysis back with values flagged as abnormal can feel like a verdict. It isn't. Here's what the numbers actually mean, what causes them to fall out of range, and what the evidence says about improving them.
If your labs came back showing high LH and low testosterone, you probably Googled it and found either nothing useful or a wall of medical jargon. Here's a plain-English breakdown of what's actually happening, why it matters for fertility, and what to do next.
Your semen analysis came back normal. Sperm count, motility, morphology — all within range. And yet conception isn't happening, or pregnancies keep ending early. If that sounds familiar, sperm DNA fragmentation (SDF) may be the piece of the puzzle nobody has looked at yet. Here's what it is, how oxidative stress drives it, and what you can actually do about it.
