Gray's Anatomy

I have a question that I’m too embarrassed to ask my doctor. I was reading Gray’s Anatomy and it says that the left testicle is supposed to be slightly larger and to hang slightly lower than the right testicle. However, in my case it is the right testicle that hangs lower and is larger.

I’m worried that this could be the result of there being something wrong with my left testicle. Could this be, or do you think that it could just be a genetic quirk?
