testicular health matters

Normal boxers and briefs increase median daytime scrotal temperature by about 1.4 °C (2.5 °F)! Did you know that sperm count decreases by 40% for every 1 °C (1.9 °F) increase of median daytime scrotal temperature? Overheating is also linked to testicular shrinkage and impaired testosterone production.

It's an emergency and your testicular health is on the line. The modern man needs improve his sperm, testosterone, and testicular health. That's why we made Stud Briefs. For men who care about being a man.
