​- TOMMY J.

YOUR 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? Testicular overheating is also linked to smaller testicles and lower testosterone levels.

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 men.
