## Features

- SITTING DAMAGES SPERM - The scrotum hangs for a reason. Studies show we overheat our testicles from sitting office jobs, sitting driving jobs, hot climates, varicocele, and high BMI. This heat reduces sperm motility and morphology, damages DNA, and reduces sperm count by up to 90%. Heat is a major contributor to male infertility

- IMPROVE YOUR ODDS - when trying to conceive or preparing for IVF, every advantage counts
- SOFT, COMFORTABLE, AND EASY TO USE - Adapts to all body shapes; Grab and go; Use throughout the day whenever sitting longer than 20 minutes at the desk, driving, and watching TV
- MAKE BETTER SPERM TODAY - Whether trying to get pregnant naturally, or as male fertility supplement to improve sperm quality before IVF, take charge of your sperm health today; Your kids are worth it
- KIT INCLUDES 2 ICE PACKS AND 1 SLEEVE - Allows longer cooling sessions

## Questions & Answers

**Q: How often should I use this, and how long does it take to see improvements?**
A: Hi! Use The Underdog throughout your day whenever sitting for longer than 15-20 minutes (temperature danger zone). e.g. when driving, sitting at work, and  relaxing at home. 
Sperm take roughly 2 ½ to 3 months to fully mature. So any healthy lifestyle changes including using The Underdog may take this long to show up in improvements to sperm count or quality.

**Q: Can this be used when riding bicycle?**
A: Its pretty small and compact. I'm not 100% sure, but I would say yes.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent quality and design
*by G***K on April 18, 2019*

No detail was spared when designing this clever little ice pack kit. The packaging, branding, and quality are all top notch with careful consideration to every detail and feature. The ice packs freeze fast and stay cold long. The wedge shape makes it comfortable and discrete. The magnetic closure on the sleeve is a nice addition and makes it quick and easy to open or close without messing about with velcro or other fasteners. Nice work Underdog! Thanks for spending time to get the details right!

### ⭐⭐⭐⭐ Effective, but expensive for what it is
*by E***D on June 6, 2022*

The real secret sauce of this is the case. Any ice pack can keep you cold but they wouldn’t last very long. The case allows the ice pack to stay cold longer. It doesn’t feel very cold, but it lasts a long time. I’m satisfied with my purchase.

### ⭐⭐⭐⭐⭐ Bought a second kit
*by B***S on April 6, 2025*

I've had good results and bought a second kit to have at the office. It would be nice if there was a model that allowed for 8h cooling while sleeping, in order to stay fresh overnight.
