Low Sperm Motility: What It Means and What Can Affect It
Low sperm motility is one of the most common abnormal findings on a semen analysis — but what does it actually mean? Learn the difference between total and progressive motility, what can cause sperm to move poorly, and what steps are worth taking if your results are below the reference range. We also explain why a single abnormal result doesn’t necessarily mean there’s a fertility problem and when it makes sense to repeat the test or consult a specialist.
How to Read a Semen Analysis Report: A Plain-English Guide to Your Results
Learn how to read your semen analysis results, understand the key parameters, and compare them with the latest WHO 2021 reference values. We explain sperm concentration, motility, morphology, vitality, TMSC and more — and what an abnormal result actually means.
Heat and Male Fertility: Can Cooling the Testicles Improve Sperm Quality?
Research suggests that keeping the testicles cooler may support sperm quality. Discover what studies say about scrotal cooling, sperm parameters, and how CoolMen makes temperature management more practical.
Testicular Cooling: How It Works and Why Temperature Matters for Male Fertility
Why are the testicles located outside the body? There’s a biological reason: sperm production requires a cooler environment than core body temperature. Discover how testicular temperature affects male fertility, what causes heat stress, and what research says about scrotal cooling.
If heat can impair sperm production, what is the best way to keep the testes cool?
Can cooling your testicles improve male fertility?
Interest in testicular cooling has grown rapidly over the last few years, but choosing the right solution isn't easy.
We compare passive cooling methods—including cooling underwear, gel packs and seat-based devices—with active thermoelectric cooling systems, explaining how each technology works, where it may help and what current research actually says.
Varicocele: Symptoms, Causes, Treatment, and Its Impact on Male Fertility
Varicocele is a common but often overlooked condition that can significantly affect male fertility. By raising testicular temperature and increasing oxidative stress, it may reduce sperm quality even in men with no obvious symptoms. Learn how varicocele is diagnosed, treated, and why maintaining optimal testicular temperature is essential for healthy sperm production.
Can Summer Heat Affect Sperm Quality? What Science Says About Male Fertility
As Europe faces another summer heatwave, many men wonder whether high temperatures can affect fertility. Here's what current scientific evidence reveals about heat, sperm quality, and protecting reproductive health during hot weather.
How Temperature Affects Sperm Quality: What Scientific Research Shows
Discover how testicular temperature affects sperm production and fertility. Learn what scientific research reveals about heat exposure and sperm quality.
