Aircon Underwear cool naturally - Patented design for men's hormone and sperm

Problem of men's underwear: Boxers can be bad, especially for sports, due to loose fitting leading to chafing. Briefs and boxer briefs provide support and tight up. However, they are restrictive and don’t allow body heat to escape–‘Heat can reduce sperm count and testosterone production‘ University of Wisconsin. Harvard University Associate Professor Jorge Chavarro found: ‘Beyond providing additional evidence that underwear choices may impact fertility, our study provides evidence, for the first time, that a seemingly random lifestyle choice could have profound impacts on hormone production in men at both the level of the testis and the brain’. How can we get underwear without those issues? That's why we design Aircon Underwear.
