When you combine compression, overheating, and varicocele, you get testicular damage. If you copress the testicles you prevent them from dropping down to cool-down when they're over-heated. From here, we know that varicocele disrupts normal testicular cooling. So, the testicles are almost always wanting to drop down to cool. But if you compress them up, they cannot even do this. Add poor heat ventilation to this, and you not only trap lots of heat, but your testicles have no way of cooling down. This means testicular damage--as in testicular shrinkage, infertility, and impaired testosterone.

Think of it this way: When the testicles are too hot, the cremaster muscle loosens and distances the testicles from the body in an attempt to cool the testicles. So, if you take away this ability with compression, and also add heat stress--that's a really bad idea. ​

Now, here that's actually that most doctors are getting wrong. Doctors are recommending supportive underwear for testicular pain, varicoceles, infertility, etc. They're treating the testicles like a joint "provide compression to improve blood circulation". But, the testicles aren't a joint! While some light compression is likely beneficial, too much compression is not. Moreover, compression with over-heating leads to terrible stress & damage to the testicles.

​Proper Testicle Support: Underwear that provides testicular support or compression Must also provide adequate cooling. ​

Briefs, Boxer Briefs, & Jockstraps: Squish penis and testicles into a ball and trap lots of heat. Trapped heat damages the testicles, and causes both pain & dysfunction. We're talking about serious decrease in both fertility and testosterone production, and at times testicular shrinkage. So while this might seem like a light topic, it is actually very important.

Boxers, & Trucks: Do a slightly better job at cooling the testicles, but, they still trap a lot of heat and provide no scrotal support. This means both overheating and scrotal sagging. We can do better.

Going Commando: Going commando is a great way of keeping the testicles cool. And... It works! But, unfortunately, it does not provide testicular support, leading to scrotal sagging. So, it is better than boxers and trucks.

The Best Underwear For Cooling The Testicles: This type of underwear maximizes cooling while providing testicular support & penis/testicle separation.
