Alright, well my testicles are about 3x different in size. My left testicle is about the size of a grape, probably a bit bigger.. and my right testicle is about the size of a chicken egg. Sometimes they're sore, but not very much. Is this normal? I've looked it up and found that if it's soft (the bigger testicle) and feels like there's maybe a fluid inside, it could be a hydrocele. I've also read that if it's hard, it could be testicular cancer. I'm not sure what's wrong, but I'm going to my family doctor on tuesday. Just thought I'd ask a professional ahead of time. What do you think?
