Undescended testicles can be treated with hormone therapy or surgery to bring the testicles down into the scrotum. The fertility of patients with undescended testicles depends on the time of treatment. The later the diagnosis and treatment, the lower the chance of having children.

Undescended testicles can occur in 3% to 4% of children at birth. Many families find that their children have undescended testicles but wait until they are adults to examine and perform surgery. This is completely wrong because leaving the testicles in the abdomen for a long time is not good. So when should surgery be performed on children with undescended testicles?
