Lol guys I wish... mine swelled up to be the size of an orange lol i looked a sight carrying it around with me in my hands, i wish i had atrophy!! btw I dont think its atrophy most testicles are different sizes i think form memory 2.5 cms is the average and well from eperience yes the bundles of tubes do get in the way and its hard to get a feel for what size thy exactly are so guys dont panic, if you think theres a problem go visit the doctor otherwise dont worry.
