THE MOST IMPORTANT FACTOR FOR TESTOSTERONE PRODUCTION

Proper testicular care is the most important factor for testosterone production. This means you need to have good blood circulation and minimize testicular hyperthermia. Supportive underwear that's therapeutic for the testicles does just that--it helps compress the testicles to improve testicular blood circulation, and keeps the testicles significantly cooler than normal underwear to activate the enzymes responsible for fertility & testosterone production.
