one's balls aren't the hottest part of the body. In fact they are usually 2 degrees cooler than the rest of the body and that's why they are external. 96 degrees F is optimal for creating sperm.

It's one the easiest parts to regulate temperature-wise in order to maintain homeostasis.

9th grade biology right there so I'm not sure if it's 100% correct.
