Men struggling with fertility might as well have a fire going on in their pants: Their sperm-making parts are actually hotter than men who have no fertility problems at all. To combat this, an Ashland, Va.-based company is selling briefs that promise to keep the family jewels nice and cool.

The briefs, appropriately called Snowballs, began last year as a Kickstarter campaign by Joshua Shoemake. Snowballs sound funny, but the story behind them is serious.

The idea began with several couples struggling to conceive. One couple had a miscarriage. They were told to give up and try adopting. Then a gynecologist told them that elevated scrotal temperature can be a major cause of infertility in men, according to the company.

Sick of holding melting freezer bags on their crotches, the guys worked on a design for organic cotton boxer-briefs with space for a “SnowWedge" gel pack made from carboxymethyl cellulose sodium that could stay cool for at least 30 minutes. Using the briefs helped one of the couples have a baby girl, the company said.

Although Snowballs didn't reach their $20,000 goal on Kickstarter, the people behind it did launch a retail site that now sells a $59 “fertility pack" containing two Snowballs boxer-briefs and three SnowWedges. Hat tip to Gizmodo.

When their Kickstarter campaign was still under way last spring, CNET's Eric Mack suggested that it might have raised more money if it had been July instead. “I advise any man planning a summertime trip to Houston to bring along a pack, regardless of your sperm situation," he wrote.

Given the arctic weather that's been blasting the country recently, nature might be Snowballs' biggest competition. Spend enough time outside, gentlemen, and it's probably about the same as putting a frozen gel pack in your underpants. But after all this melts in a few months, better get back to the freezer.
