|The Snowball Underwear pictured above does just that, by featuring a removable gel-pack (the SnowWedge™) that rests atop that most vital of body parts, and could help boost your chances at conceiving. Haha!
"They should increase both sperm quality and quantity, and they should give you a better chance to conceive at minimal cost, but fertility science is complex, and you’ll also want to consult with a urologist (for varicoceles), as well as your fertility specialist. Snowballs may end up being just a supplemental treatment for you."
If you want to cool 'your balls', it’ll cost you a $55 pledge on Kickstarter, and for which you get three pairs of underwear along with 3 gel wedges.
