Just wondering what could cause this...? my tesitcles used to be much bigger.. like the size of a small plum.. now they're only about the size of grapes..? also, there is a mass of tissue, seems to feel like a bunch of tubes behind them that I can feel. i've been checked for cancer of the testicles and I don't have it... is there any way my boys will ever get back to they're normal size..!? HELPP.. i need some answers....
