We built Snowballs™ to maximize fertility, then quickly discovered what many of our customers already knew: lower the temperature of your testicles, and you optimize the production of natural testosterone.

Those of you in the bodybuilding community have probably heard about the techniques of the great Russian bodybuilders of the ’70s and ‘80s – one of which was testicular icing, which creates better conditions for the production of endogenous testosterone. There have even been studies showing this effect, including one by Nakamura et al. demonstrating that testes perform optimally at 31-36 °C (87-96 °F) – quite a bit below body temperature – and warmer temperatures will affect not only sperm production, but DNA synthesis and testosterone production. Another study showed that just 15 minutes of increased heat in rat testes reduced testosterone dramatically (with a 65.4% reduction in testicular weight!).

It turns out that the same precursor hormones (LH and FSH) that start sperm production also start testosterone synthesis – the two processes actually complement each other, and one doesn’t exist without the other. So by icing with Snowballs™ you’re not only improving your sperm, but you’re also helping to maximize natural testosterone production. And vice versa. Pretty cool, huh?
