I'm 16 And One Of My Testicles Is A Lot Larger Than The Other One, Is This A Problem?

I am 16 also, but not a boy. This isn't really anything to worry about. About every women have one breast bigger and fuller than the other. If you are really worried consult a doctor and he will explain.

No, its perfectly normal. My boyfriends balls are the same!! Don't worry!

Yeah, like monique_v said you have nothing to worry about, it happens to women too (just women don't have testicles). I'm sure if they still work you have nothing to worry about. I'm sure many men have that issue it's just women know about their abnormality more than men because women aren't afraid to talk about that kind of stuff.

I'm not sure if this is a medical fact but I think every guy (once the testicles drop) has one larger than the other.  With me it's me left testicle. It hangs lower than the right one. Why? I don't know but don't worry, you're okay.
