Ice The Boys.
Targeted cooling during sauna use — because heat affects your testosterone and fertility.
Heat kills your T-levels. And your swimmers.
Sauna heat doesn’t just make you sweat — it actively suppresses testosterone production. Studies show that heat exposure reduces serum testosterone levels, affecting energy, muscle recovery, libido, and mood. For men who train hard and sauna regularly, that’s working against yourself.
And if you’re planning a family, the stakes are even higher. Elevated scrotal temperature reduces sperm count by up to 40%, and the effects can linger for months. Your body needs 74 days to produce new sperm.

Backed by science.
A 2013 study published in the Journal of Endocrinological Investigation found that testicular heating significantly reduced testosterone levels in healthy men.
Research in Human Reproduction showed that scrotal cooling restored hormonal profiles in men with heat-induced testosterone suppression.
The International Journal of Andrology (2007) confirmed that wet heat exposure significantly impaired sperm production, with effects lasting up to 6 months.
Heat effects on testosterone & sperm production
“We believe men shouldn’t have to choose between wellness and fertility.”
Ice The Boys was born from a simple question: why isn’t there a solution for men who love the sauna but want to protect their reproductive health? We partnered with urologists and product designers to create a cooling pack that’s effective, comfortable, and discreet. No compromises.
