An undescended testicle almost always requires surgery, because it causes a number of medical issues. An undescended testicle is more likely to cause hernias
, tumors, or become injured.For this reason, surgery
is required to correct an undescended testicle.
On the other hand, a retractile testicle does not require any treatment. It is usually the body’s own defense mechanisms that cause the testicle to retract and it descends on its own.
