Your underwear can save your sperm. Or at least that's what Snowballs believes. What's Snowballs? A type of cooling underwear that basically uses ice packs for "scrotal cooling". Ball air conditioning, basically. It's for the kids.
The idea behind the underwear is that tests of men with fertility problems tend to "be naturally warmer by an average of over one degree Celsius". That little number adds up to a big difference and by lowering temperature in the precious area can improve the motility of the sperm.
The Snowballs underwear is made from organic cotton and cools with freezable gel packs in a wedge shape made of Carboxymethyl Cellulose Sodium. Here's how Snowball describes it:
They are designed with a central hinge that cleverly molds the SnowWedge™ around your body to reach maximum surface area and maximum cooling. Unlike normal icepacks, they won't get you wet, and you won't have to sit there holding ice for hours
$US60 gets you two pairs of boxers and three snow wedges. Cool on, guys.
