Yes. It is common for guys to have slightly different size testicles. Usually, the right testicle is larger than the left. Also, one testicle (usually the left) often hangs lower than the other.

Does it matter which testicle hangs lower?

It is entirely normal for one testicle to be bigger than the other. Many people find that the right testicle is slightly larger and the left hangs lower. A difference in size is usually nothing to worry about, though it can occasionally indicate a problem.

What does it mean when the left testicle hangs lower?

Varicoceles affect up to 15 percent of males. Like varicose veins in your legs, varicoceles may appear bulgy under the skin of your scrotum. They tend to form in the left testicle because the vein on the left side hangs lower.
