right testicle is huge left is tiny

Most men have balls that are an uneven size; one is almost always larger than the other and hangs lower than the other. One thing that could cause concern: if the larger one seems to be larger due to an inflammation or some other cause, such as a cyst. If it seems that the larger one is unnaturally large, check with a doctor.  Keeping an eye on groin health is a good idea; using a top drawer penis nutrient cream (health professionals recommend Man1 Man Oil) can help with penis health. Look for  a cream with L-arginine, which helps keep penis blood vessels functioning.
