so two things make armor “effective” 1. ability to block blows 2. ability to prevent pain testicles are flesh, so unless they’re alive they’ll start to rot and won’t block blows well. but to prevent pain, they have to be not yours. so yes but only if they’re genetically engineered to be an independently living ballsuit
Testicles are soft tissue and decrease elastic collisions, so they’d absorb force of impact from body blows and cannot effectively reflect blows from weapons. For this reason, a ballsuit may be better suited for use inside of a skin and bone suit; skin/bonesuit to reflect blows, ballsuit to absorb shock
