Is there anything more crushing to a guy's psyche than being told that his male fertility is the reason that his little soldiers aren't invading enemy territory and planting their flag? If that analogy was a little too dense, it can be tough on a guy if the reason he can't conceive is because of a problem with his plumbing.
It's with male fertility in mind that Joshua Shoemake came up with Snowballs underwear, possibly the greatest name for any product in the history of products. Shoemake had some problems in the male fertility department himself, and after icing his nether regions, he was able to conceive with his wife.
With his success, also came the idea for underwear that limited the amount of heat going to the genital area, which is a major cause of male fertility problems. The Snowballs underwear design features what Shoemake calls SnowWedges, which are small freezable gel packs that maintain a cool temperature for up to half an hour.
