Trying to Conceive?
Sperm quality matters. Our device can help.
Sitting Overheats Sperm
Sitting, driving, varicocele and high BMI will overheat the testicles, damaging up to 90% of sperm and leading to low sperm count, low morphology, and low motility. These reduce fertility when trying to conceive, and may impact offspring health.
(Ref 9, 10, 25, 26)
Introducing The Underdog
The Underdog is a patented testicular cooling device engineered to boost sperm count and improve sperm quality. It uses a wedge shaped ice pack between the seat and pants to stop overheat when sitting. And its clever double insulation prevents over-chilling and wet pants.
Underdog Prevents Overheating
The Underdog prevents testicular temperature rise, to optimize healthy sperm production. Healthy sperm are key to a healthy pregnancy and healthy children.
