How The Underdog Works
The Underdog is a patented non-invasive, low-risk cooling system designed to gently cool the scrotum and testicles to prevent sperm overheat and damage that comes from sitting. The Underdog uses an ice pack with a novel wedge shape and precision insulation system to deliver the optimal amount of cooling. It can be used whenever driving or sitting.
Why Use Cooling
Getting pregnant isn't always easy. And our offspring are the most important investment of our lives. Why not use everything at our disposal including The Underdog for the best chances of getting pregnant faster and healthier.
How to Boost Male Fertility
To optimize fertility, it's essential to maximize sperm quantity and optimize sperm quality. This means following a healthy lifestyle: eating better, taking care of ourselves, and making sure we're getting essential nutrients from food and supplements. It also means keeping our testicles cool so they're at the optimal temperature for sperm production.
Infertility and Heat
Male fertility has been plummeting among men in the western world. A shocking 2017 meta-study concluded that sperm counts are down more than 50% in the past 40 years, with a continued decreasing trend. An estimated 15% of couples now face infertility challenges, with a male factor contributing half of the time.
While there are a number of possible factors for male sub-fertility and male infertility, scientific studies suggest a correlation between reduced viable sperm count and overheat due to sitting, driving, and obesity.
The rise of the information economy means jobs requiring physical activity have dropped from 50 percent to just 20 percent since 1960. A 2017 survey found individuals employed full time now spend an average of 12 hours sitting per day. This corresponds with the 50% drop in sperm count over the last 40 years. Coincidence?
Trying to Hang Out
The scrotum hangs outside the body for a very cool reason: sperm formation is extremely sensitive to testicular overheat. The optimal testicles temperature for sperm formation is 2-3 degrees C below body temperature.
But we overheat our testicles by sitting or driving for longer than 20 minutes, wearing our normal clothing, and underlying medical conditions like obesity or varicocele. These defeat our natural cooling systems, causing scrotal temperature to rise into the danger zone harmful to sperm production.
Enter The Underdog
The Underdog is a simple, non-invasive, low-risk cooling device that keeps the scrotum in an optimal temperature range by counteracting temperature rise when sitting. It uses a gently contoured wedge-shaped ice pack that fits any body shape, and a soft sleeve with engineered thermal insulation. The Underdog slips quickly between the seat and pants to provide a precise amount of cooling and keeps the scrotum at the optimal temperature for sperm production.
And best of all, no special clothes are required!
- No awkward ice pack underwear
- No wet pants
- No discomfort
- No overheat
It's easy to make The Underdog a part of the daily routine.
Using The Underdog is super simple:
- Freeze both ice packs
- Sleeve an ice pack
- Insert The Underdog between seat and pants
See the Detailed User Guide for more detailed instructions.
The Ice Pack
The ice pack creates the perfect contoured wedge shape to adapt to every body shape and seating surface. When sleeved, simply move it towards the body to make comfortable contact with the pants and scrotum.
The kit comes with 2 ice packs so you're never without cooling.
Each ice pack lasts for 3-4 hours and will re-freeze in 2-3 hours in a standard freezer.
The sleeve uses a precisely engineered double-insulation technique for just the right amount of cooling. The sleeve is soft and comfortable, and the cooling effect is barely noticeable.
A crisp magnet closure makes for easy swapping of ice packs.
The discreet, masculine black color nearly disappears when in use.
And importantly, the sleeve is impermeable to the water vapor that causes condensation. So you won't get wet pants or a wet chair.
When to Use The Underdog
Whenever sitting for longer than 20 minutes:
- At the Office
- Relaxing at Home
How Does The Underdog Compare to Snowballs Cooling Underwear?
- The Underdog's patented insulation provides gentle, controlled cooling of 2-3 deg. C for 4 hours to keep testicles in the optimal range for sperm production.
- Snowballs provides extreme cooling for less than 30 minutes, then expires. In our probe experiment, Snowballs caused an extreme 16 deg. C scrotal temperature drop in the test subject. We question if this is effective or safe.
Comfort and Convenience
- Snowballs underwear requires special underwear which are uncomfortable, inconvenient, require trips to the washroom to swap ice packs, and may cause a bulge in the pants.
- The Underdog is very comfortable, non-intrusive, and can be easily put aside when it's time to get up and move.
