On average, testicles are 4 x 3 x 2 centimeters (cm) in size and is oval shaped. It's totally normal for man's testicles to be different sizes and for one to hang lower and behind the other. In most men the right testicle is slightly bigger and the left hangs lower. Although if the change in testicles is something you've noticed to be new and different from before then you should visit a surgeon and have it evaluated.
Next Steps
Get examined by a general surgeon if the change in size is a new development.
