Man with laptopGentlemen, heat is your enemy. That’s the message behind a new product said to enhance a man’s fertility by cooling down the "family jewels" in order to promote healthier sperm. This intimate cooling product is aptly named “Snowballs.”

The heat-is-enemy mantra is not just a marketing ploy. The creators of the Snowballs fertility pack are men who shared the journey of in vitro fertilization (IVF) with their wives but, alas, to no avail.

After years of trying to conceive (TTC), a fertility specialist suggested the problem might not be female-related infertility; it might be that the male scrotum is too hot to produce the healthiest sperm possible. This condition could be based on a male's individual metabolism or it could be aggravated by a varicocele. It could also be a combination of the two, producing a double-whammy against a man’s pursuit of fatherhood. Lifestyle choices may play a role as well.

This newly acquired information was shared and researched. However, when packages of frozen vegetables pressed snuggly against the men’s pants resulted in drippy, wet clothing spots in embarrassing places, they thought there must be a better way to keep the "jewels" on ice.

The Snowballs fertility pack was born. The pack consists of two pair of men’s 100-percent natural, organic underwear that is soft, comfortable, and has just enough “give” to avoid crowding, and thus overheating, the anatomical target. The specially designed underwear comes in assorted sizes and contains compartments for holding the patent-pending SnowWedge that brings cool, non-toxic relief without the mess of frozen veggies.

Along with tips for everyday means of keeping one’s junk conceivably cool, the problem of heat is explained. And so are varicoceles.

  • Heat: Sperm health (mobility and count) can suffer when scrotal temperature rises just a few degrees but cooling can restore fertility when excess heat is the enemy. Heat affects the enzymes responsible for sperm and testosterone production. Most infertile men are simply too hot. Too-tight briefs and pants, hard work-outs, steamy saunas and hot showers all contribute to scrotal temperature. Laptops, used on the lap, can raise temps by several dangerous degrees.
  • Varicoceles: Between 15 and 20 percent of all men have these swollen or enlarged veins in the scrotum, similar to varicose veins in the legs. The added blood flow they cause is hot. Cooling helps but surgical intervention is an option, too.

Does the cooling effect of Snowballs actually help produce children? It's possible. Snowballs is a new product and healthy sperm production and baby-making take time but, after years of expensive failed attempts at IVF and a few months of scrotum-cooling research, one Snowballs creator is the cool, proud papa of a beautiful baby girl.
