Undescended Testis in Boys: Why Early Treatment Matters

What Is Undescended Testis?

Undescended testis in boys is a condition where one or both testicles do not move down into the scrotum before birth. Normally, testicles form inside the belly of a baby boy. During the last months of pregnancy, they travel down into the scrotum. However, in some boys, this does not happen as expected. Instead, the testicle stays in the belly or groin area. As a result, the scrotum may look or feel empty on one side. This condition is common in newborn boys, especially those born early.

Symptoms and Signs

Parents often notice signs of undescended testis during diaper changes or baths. For example, you may see or feel that one side of the scrotum is smaller or empty. Other signs can include:

One or both testicles missing from the scrotum

Scrotum looks uneven or less full

Groin swelling or a lump in the groin area

No pain or discomfort in most cases

Still, some boys may not have any obvious symptoms. Therefore, regular check-ups are important for early detection.

Causes and Risk Factors

There are several causes of undescended testis in boys. Sometimes, the exact reason is not known. However, certain factors can increase the risk. For instance, boys born early (premature) are more likely to have this condition. Other risk factors include:

Family history of undescended testis or related problems

Low birth weight

Problems during pregnancy, such as diabetes in the mother

Exposure to certain chemicals or smoking during pregnancy

Genetic conditions or hormone issues

Additionally, some studies suggest that environmental factors may play a role. Still, more research is needed to fully understand all causes of undescended testis in children.

Diagnosis

Doctors usually diagnose undescended testis in boys during a physical exam. At birth, the doctor checks if both testicles are in the scrotum. If one or both are missing, further checks may be needed. Sometimes, imaging tests like ultrasound help find the testicle. However, not all cases need imaging. If the testicle cannot be found, your doctor may suggest seeing a specialist. Early diagnosis is important for the best outcome. Therefore, parents should seek medical advice if they notice any signs.

Why Early Treatment Matters

Early treatment for undescended testis is very important. Treating the condition before age one lowers the risk of future problems. If left untreated, there are several risks of untreated undescended testicle. For example, boys may face:

Higher risk of infertility or trouble having children later

Increased chance of testicular cancer

Greater risk of testicle injury or twisting

Possible hernia or swelling in the groin

Because of these risks, doctors recommend early treatment. This helps protect a boy’s health and future well-being.

Treatment Options

Treatment for undescended testis in boys often involves surgery. The main goal is to move the testicle into the scrotum. Treatment steps may include:

Regular check-ups to see if the testicle moves down on its own in the first few months

Surgery (orchiopexy) if the testicle does not move by 6 to 12 months of age

Follow-up visits to check healing and testicle health

Sometimes, hormone therapy is suggested, but surgery is most common. After treatment, regular monitoring helps ensure the testicle grows and works well.

Prevention and Parental Guidance

While it is not always possible to prevent undescended testis in boys, parents can take steps to support their child’s health. For example, mothers should avoid smoking and harmful chemicals during pregnancy. Regular prenatal care also helps lower risks. After birth, parents should:

Attend all well-baby check-ups

Watch for signs of an undescended testicle during diaper changes

Talk to the doctor if they notice anything unusual

Follow the doctor’s advice for treatment and follow-up care

With early action and regular care, most boys recover well and lead healthy lives.
