Undescended testicles are the most common developmental defect in males. The incidence of undescended testicles in boys is about 3 - 4% at birth, often occurring in low birth weight, premature birth, and twins. However, undescended testicles still pose many potential risks in adults if not treated early.

Currently, there are several methods of treating undescended testicles such as medical treatment with hormones or surgical treatment such as open surgery or laparoscopic surgery. Depending on each case, the doctor will prescribe the appropriate method to bring the best treatment results.

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?

Undescended testicles are a common congenital abnormality of the reproductive system in boys. If the disease is not detected and treated early, it can cause loss of testicular function and even cause testicular cancer later on.
