Is there any "normal" physiological reason for one of the the testicles to be slightly larger than the other?

Are there also any medical causes that could explain the same condition?

Some people have DNA, others have C30H46O3.

Are you right testicled, or left testicled?:-)

I think you will find that there are minor differences between almost anything that you have 2 of.

you might be interested in this this article:

Laterality. 2004 Apr;9(2):189-99.

Right-left and the scrotum in Greek sculpture.

McManus IC.

The scrotum in humans is asymmetric, the right testicle being visibly higher
than the left in most men. Paradoxically, it is also the case that the right
testicle is somewhat larger, rather than smaller, as might be expected. Greek
classical and pre-classical art, which took great care in its attention to
anatomical detail, correctly portrayed the right testicle as the higher, but
then incorrectly portrayed the left testicle as visibly larger. The implication
is that the Greeks used a simple mechanical theory, the left testicle being
thought to be lower because it was larger and hence more subject to the pull of gravity.
The present study examines data on scrotal asymmetry in more detail, and puts them in
the context of Greek theories of functional differences between the right side and the left side.

the human body is inherantly asymetrical anyway, there are no 2 components identical in mass or volume, it is Not a "Condition" per se, and certainly no cause for concern :)

So what if the opposite is true, then?

And left/right from who's perspective? I never remember how left & right work with regard to the body...

Then you must have some sort of genetic disease and must be irradicated from the race.

Actually nothing... and there's nothing wrong if the size changes, favoring one or the other, if you're going through puberty... this too is normal.

Well, if you can remember which hand is your right hand and which foot is your right foot, it works the same way with the testicles.:-p

No that would be a small hard lump on the testicle, not one bigger than the other, whatever side it was.

What are you trying to do, scare the crap out of us all ?!

1 is more active then the other, you really only need 1 to produce your sperm so you really only use 1, which is why it is larger. The other one is an evolutionary backup plan.

Oh year, I guess that would make sense.

Like kidneys...? (Except as far as I know they're both the same size.)

Are both testicles used for the same function? I was told once that one produces sperm and the other produces hormones, but that's probably wrong.

No, they both produce sperm and hormones...in this case testosterone (steroid hormone). Hence if you lose one it's not the end of the world.
