The Hidden Cost
The Science Is Clear — Heat Kills Sperm
Your scrotum exists outside your body for one reason: sperm needs to be 2-4°C cooler than core body temperature. A single sauna session overwhelms this cooling system for hours. The research is unambiguous.

Common Questions
Do I really need these if I sauna regularly? +
If you sauna more than once a week, the research says yes. A single session can suppress sperm production by over 50%.
Will people notice I'm wearing them? +
No. TestGuard looks like normal athletic shorts. 7-inch inseam, flat-felled seams, standard fit.
How long do the gel packs stay cold? +
Approximately 30 minutes in a standard 80°C sauna. After that, the 3-layer construction provides passive insulation.
Can I use these if I'm not trying for a baby? +
Yes. Sperm quality affects testosterone, energy, and overall vitality — not just fertility.
What sizes do you offer? +
XS through 3XL, sized for UK/EU standards. 30-day free returns and exchanges.
