Trying to Get Pregnant?
Sperm count and sperm quality matter when trying to conceive. Boost male fertility the natural way.
Sitting Damages Sperm
Our testicles hang for a reason: to produce healthy sperm, they need cool temperatures.
But sitting, driving, varicocele and high BMI all overheat the testicles. Studies show even mild overheating over time damages up to 90% of sperm and leads to low sperm count, poor morphology, low motility, and DNA fragmentation, any of which can cause male infertility.
[Studies 9, 10, 25, 26]
Introducing The Underdog
The Underdog uses a wedge shaped ice pack and innovative insulation system. This cools the testicles to reverse the overheating from sitting - by 3 degrees Celsius to be exact!
Simply sit, then slide the Underdog between the seat and your body.
The Underdog is engineered to never over-cool.
The Underdog Prevents Overheating
The Underdog's gentle cooling keeps testicles out of the temperature Danger Zone when sitting.
This maintains an optimum environment for healthy sperm production.
Healthy sperm are critical for conceiving and for carrying to term, whether trying to conceive naturally or before IVF.

Promising enough that we are offering our men the option of using these devices as a part of their therapy for infertility.
Dr. C. L.
Healthy sperm are very sensitive to overheating. The Underdog keeps the testes at the perfect temperature. Wonderful and discrete. Highly recommended.
Quality build and packaging. The ice pack is comfortable enough to use for a few hours straight while keeping its "cool", and inconspicuous enough for the office.
Dr. M. S.
It's my secret weapon that I like to tell patients about. Nice and comfortable. It feels great. If you're a man, you know you need this. If you're a woman, your partner's sperm will thank you for it.
It cools down my balls and raises sperm counts. Would highly recommend to those who want to conceive.
Pretty impressed with this product. First, it comes with two ice packs which is great for a long day. Next, it feels very comfortable when using. Temperature is perfect. Not too cold or hot.
