Symptoms

Having an undescended testicle does not cause pain or other symptoms. It may cause the scrotum to look:

• Smoother and less rounded than normal on one or both sides.
• Larger, fuller, and better developed on the side with a testicle. The side without a testicle usually is smaller and flatter.

Also, you will not be able to feel the rounded mass of the testicle in the scrotum on the side where it has not descended.
