Is there any way of mitigating testicular pain?

It hurts more than other regions due to the nature and number of nerves there.

Having a response to being hit in that region that causes a lot of pain is a great evolutionary incentive to keep that area safe; after all, that's the only area that can pass on your genes. It also allows that area to be sensitive to other stimulation, another great evolutionary boon. Unfortunately, probably due to sperm production having to happen out of the body, they are very unprotected.

As to why nature has left us with no coping mechanism it's again probably due to the benefit of keeping this area safer; if you make it very painful then the animal will try even harder to keep it safe.
