Undescended testis, also known as cryptorchidism, is a common pediatric urology condition affecting newborn boys. It occurs when one or both testicles fail to move into their normal position in the scrotum before birth. This condition raises concerns for parents about their child's health, future fertility, and the need for treatment. Understanding the causes, diagnosis, and treatment options can help families make informed decisions and ensure the best care for their child.
What Is Undescended Testis?
Undescended testis means that one or both testicles have not moved down into the scrotum, the pouch of skin below the penis, by the time a baby is born. Normally, testicles develop inside the abdomen and descend into the scrotum during the last months of pregnancy. When this process does not complete, the testicle remains in the abdomen or groin area.
This condition is one of the most common male reproductive anomalies in children and can affect one or both sides. It is important to identify and treat undescended testis early to avoid complications.
Why Does the Testicle Not Move Into Its Normal Position?
Several factors can cause the testicle not to descend in a baby:
Hormonal issues: The hormones that trigger testicular descent may be insufficient or imbalanced.
Physical blockage: Abnormalities in the structures guiding the testicle can prevent movement.
Genetic factors: Some children inherit a tendency for cryptorchidism.
Prematurity: Babies born early are more likely to have undescended testis because descent happens late in pregnancy.
Understanding the cause helps doctors decide the best treatment approach.
How Common Is Undescended Testis in Newborns?
Undescended testis occurs in about 3% of full-term newborn boys. The rate is higher in premature babies, reaching up to 30%. In many cases, the testicle descends on its own within the first few months after birth. However, if it remains undescended after 6 months, medical evaluation is necessary.
When Should Undescended Testis Be Treated?
If the testicle has not descended by 6 months of age, doctors recommend treatment. Waiting beyond this age increases the risk of complications such as:
Reduced fertility later in life
Increased risk of testicular cancer
Testicular torsion (twisting)
Hernia development
Early treatment improves outcomes and preserves testicular function.
Can This Condition Affect Fertility Later in Life?
Yes, undescended testis can affect fertility if left untreated. The testicle develops best at the cooler temperature of the scrotum. When it remains inside the abdomen or groin, the higher temperature can damage sperm-producing cells. This damage may reduce sperm count or quality, leading to fertility problems in adulthood.
Timely undescended testis treatment helps protect fertility by moving the testicle to its proper position.
How Is Undescended Testis Diagnosed?
Diagnosis usually happens during a physical exam by a pediatrician or pediatric surgeon. The doctor will:
Palpate the scrotum and groin to feel for the testicle
Check for any swelling or hernia
Use ultrasound imaging if the testicle is not palpable to locate it
Early diagnosis is key to planning effective treatment.
What Is Orchidopexy and How Is It Performed?
Orchidopexy surgery is the standard treatment for undescended testis. It involves moving the testicle from its abnormal position into the scrotum and fixing it there. The procedure is usually done under general anesthesia and takes about one to two hours.
Steps of orchidopexy surgery include:
Making a small incision in the groin or lower abdomen
Locating the undescended testicle
Gently freeing it from surrounding tissues
Creating a pouch in the scrotum
Securing the testicle in place with stitches
This surgery is considered safe and effective, with a high success rate in restoring normal testicular position.
What Should Parents Expect After Surgery?
After orchidopexy surgery, parents can expect:
Mild pain or discomfort, managed with prescribed painkillers
Swelling and bruising around the surgical site for a few days
Limited physical activity for about 2 weeks
Follow-up visits to check healing and testicle position
Most children recover quickly and return to normal activities within a few weeks.
Is Long-Term Follow-Up Necessary?
Yes, long-term follow-up is important to monitor testicular growth and function. Doctors recommend regular check-ups during childhood and adolescence to:
Ensure the testicle remains in the scrotum
Detect any signs of testicular atrophy or other complications
Monitor fertility potential as the child grows
Ongoing care helps address any issues early and supports healthy development.
