## Description

Underdog Male Fertility Cooling Kit: Boost : desertcart.co.uk: Health & Personal Care

Review: 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!
Review: Not sure if this did the trick but 2 months into using this along with other male fertility pills we are pregnant 🙂. Prior to using this we had been trying to conceive for over a year. The product itself looks kind of odd and looks like something you would possibly torture your nuts with 😬. It is actually surprisingly comfortable and doesn't hurt or feel uncomfortable at all. You can actually forget that its there. For those trying to convince i would definitely give it a shot. Especially with the high cost of ivf. I wish you all the best of luck and hope this was helpful.

## 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.

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.
