Introduction to Undescended Testis Surgery
Undescended Testis Surgery, also known as orchiopexy or orchidopexy, is a pediatric urological procedure that moves an undescended testicle into the scrotum. Doctors call the underlying condition cryptorchidism.
Normally, the testicles move from the abdomen into the scrotum before birth. However, one or both testicles may remain in the abdomen or groin.
Although some testicles descend naturally during early infancy, spontaneous descent becomes unlikely after six months of corrected age. Therefore, timely specialist assessment is important.
In this guide, JDMeditech explains undescended testes, diagnosis, surgical techniques, instruments, benefits, risks, recovery, and frequently asked questions.
What Is an Undescended Testis?
An undescended testis is a testicle that has not reached its normal position inside the scrotum.
Sometimes, the testicle remains in the groin. In other cases, it lies inside the abdomen or cannot be located during examination.
Consequently, the scrotum may appear empty or less developed on the affected side.
Furthermore, testicles outside the scrotum may face a higher temperature than usual. Over time, this can affect the cells involved in future sperm production.
Understanding Normal Testicular Descent
The testicles develop inside the abdomen during fetal development. Before birth, they usually move downward through the inguinal canal into the scrotum.
However, this process may remain incomplete in some infants. As a result, one or both testicles stay outside their normal position.
Additionally, premature infants have a higher likelihood of undescended testes at birth.
What Causes Undescended Testes?
The exact cause is often unclear. However, several developmental and hormonal factors may contribute.
For example, incomplete fetal testicular descent can occur because of differences in hormonal signaling or anatomy.
Furthermore, genetic and pregnancy-related factors may influence development.
Common Risk Factors
- Premature birth
- Low birth weight
- Family history of undescended testes
- Selected genetic conditions
- Hormonal or developmental differences
- Associated congenital conditions
Nevertheless, many children with undescended testes have no identifiable risk factor.
Types of Undescended Testes
1. Palpable Undescended Testis
A palpable testis can be felt during physical examination. For example, the doctor may locate it in the groin.
Therefore, an inguinal or scrotal surgical approach may be suitable.
2. Non-Palpable Undescended Testis
A non-palpable testis cannot be felt during examination. It may lie inside the abdomen, be very small, or be absent.
Consequently, a specialist may use examination under anesthesia and diagnostic laparoscopy to determine its location.
3. Unilateral Undescended Testis
Unilateral cryptorchidism affects one testicle. Meanwhile, the other testicle lies in the scrotum.
4. Bilateral Undescended Testes
Bilateral cryptorchidism affects both testicles. Furthermore, newborns with two non-palpable testes require prompt specialist evaluation for possible hormonal or developmental conditions.
5. Acquired Undescended Testis
Sometimes, a testicle that previously occupied the scrotum moves upward and no longer stays there.
Therefore, clinicians should evaluate a newly detected undescended testis even in an older child.
Undescended Testis vs Retractile Testis
An undescended testis and a retractile testis are different conditions.
A retractile testis can usually be moved into the scrotum during examination and remain there temporarily without tension.
In contrast, a true undescended testis cannot be positioned normally in this way.
Therefore, retractile testes generally need regular follow-up rather than immediate surgery.
| Feature | Undescended Testis | Retractile Testis |
|---|---|---|
| Position | Outside normal scrotal position | Moves between scrotum and higher position |
| Examination | Cannot remain normally positioned in scrotum | Can usually be placed in scrotum temporarily |
| Typical Management | Specialist evaluation and often surgery | Regular monitoring |
| Follow-Up | Postoperative or specialist follow-up | Monitoring until puberty |
Signs and Symptoms of an Undescended Testis
The main sign is the absence of one or both testicles from the scrotum.
Usually, the condition does not cause pain. However, associated problems may occasionally cause discomfort.
- Empty or partly empty scrotum
- One testicle not visible or palpable in the scrotum
- Asymmetrical scrotal appearance
- Testicle felt in the groin
- Associated inguinal hernia in selected cases
- Abnormal testicular position discovered during routine examination
Importantly, sudden groin or scrotal pain requires urgent assessment because testicular torsion or another acute condition may be present.
How Is an Undescended Testis Diagnosed?
Diagnosis usually begins with a careful physical examination.
First, the clinician checks the scrotum and groin. Next, the doctor determines whether the testicle is palpable.
Additionally, the healthcare team reviews the child’s birth history and previous examinations.
However, routine ultrasound, CT, or MRI is generally not recommended before specialist referral because these tests rarely change management.
For a non-palpable testis, the specialist may recommend examination under anesthesia followed by diagnostic laparoscopy.
When Should a Child Be Referred to a Specialist?
Children whose testicles remain undescended at six months of corrected age should receive timely specialist evaluation.
Furthermore, newly diagnosed undescended testes in older children also require assessment.
Importantly, newborns with bilateral non-palpable testes need urgent specialist investigation rather than routine observation.
What Is the Best Age for Orchiopexy?
Guidelines recommend performing orchiopexy between six and twelve months of age whenever feasible.
However, surgery should generally be completed by eighteen months at the latest.
Therefore, early referral helps avoid unnecessary treatment delays.
Nevertheless, older children with undescended testes should still receive specialist assessment.
Why Is Undescended Testis Surgery Recommended?
Orchiopexy aims to place a viable testicle in the scrotum.
Furthermore, early treatment may help preserve future fertility potential and makes the testicle easier to examine.
Possible reasons for treatment include:
- Persistent undescended testis after six months
- Testicle located in the groin
- Intra-abdominal testicle
- Acquired undescended testis
- Associated inguinal hernia
- Concern about future testicular function
- Need for examination and long-term monitoring
However, surgery does not eliminate every long-term risk associated with cryptorchidism.
Treatment Options for Undescended Testes
1. Early Observation
Doctors monitor some infants during the first months of life because spontaneous descent may occur.
However, persistent undescended testes after six months are unlikely to descend naturally.
2. Orchiopexy Surgery
Orchiopexy is the standard treatment for a viable undescended testicle requiring repositioning.
Consequently, the surgeon moves the testicle into the scrotum and secures it in an appropriate position.
3. Laparoscopic Management
For non-palpable testes, laparoscopy helps identify an intra-abdominal testicle or determine whether it is absent.
Furthermore, the surgeon may perform treatment during the same operation when appropriate.
4. Staged Reconstruction
Selected high intra-abdominal testes require a staged surgical approach.
Therefore, the surgeon may plan more than one operation to achieve a suitable position.
5. Orchiectomy in Selected Cases
Removal may be considered when the testicle is severely abnormal, nonviable, or presents other specific concerns.
However, this decision requires careful specialist assessment and is not the routine treatment for young children with a viable testis.
Types of Undescended Testis Surgery
1. Inguinal Orchiopexy
Inguinal orchiopexy is commonly used for a testicle that can be felt in the groin.
The surgeon mobilizes the testicle and positions it inside the scrotum.
Furthermore, the surgeon may repair an associated patent processus vaginalis or hernia when present.
2. Scrotal Orchiopexy
Selected low-lying palpable testes can be treated through a scrotal incision.
Consequently, this approach may reduce the need for a separate groin incision.
However, the surgeon selects the approach according to anatomy.
3. Laparoscopic Orchiopexy
Laparoscopic orchiopexy uses a camera and compatible instruments through small abdominal incisions.
For example, the surgeon may identify an intra-abdominal testicle and assess whether it can reach the scrotum safely.
Therefore, laparoscopy is particularly useful for non-palpable testes.
4. Fowler-Stephens Orchiopexy
Fowler-Stephens orchiopexy is a specialized approach for selected high intra-abdominal testes with limited vessel length.
The technique relies on alternative blood supply to the testicle.
Furthermore, the procedure may be performed in one or two stages.
However, testicular atrophy remains an important risk.
5. Two-Stage Orchiopexy
Some testicles cannot reach the scrotum safely during one operation.
Therefore, the surgeon may plan staged treatment to improve the chances of successful positioning.
Comparison of Orchiopexy Surgical Techniques
| Technique | Typical Application | Important Consideration |
|---|---|---|
| Inguinal Orchiopexy | Palpable inguinal testis | Common conventional approach |
| Scrotal Orchiopexy | Selected low-lying palpable testes | May use a single scrotal incision |
| Laparoscopic Orchiopexy | Selected intra-abdominal testes | Requires laparoscopic equipment |
| Fowler-Stephens | High intra-abdominal testis | Risk of reduced blood supply and atrophy |
| Two-Stage Orchiopexy | Selected complex cases | Requires a second planned procedure |
Preparation Before Undescended Testis Surgery
Preparation begins with a pediatric surgical assessment.
First, the specialist examines the child’s testicular position. Next, the healthcare team reviews general health and medical history.
Additionally, the surgeon explains the selected approach and possible complications.
- Medical history review
- Physical examination
- Assessment of testicular position
- Evaluation for associated hernia
- Review of birth and gestational history
- Assessment of bilateral non-palpable testes when relevant
- Medication and allergy review
- Anesthesia assessment
- Discussion of surgical alternatives
- Informed consent
- Postoperative care planning
Finally, caregivers receive instructions about fasting, admission, and recovery.
How Is Undescended Testis Surgery Performed?
Orchiopexy is usually performed under general anesthesia.
First, the surgical team confirms the planned operation and prepares the surgical area.
Next, the surgeon locates the testicle through the selected approach.
Afterward, the surgeon mobilizes the testicle while protecting its blood vessels and vas deferens.
Furthermore, the surgeon positions the viable testicle in the scrotum without excessive tension.
Finally, the surgical wounds are closed and postoperative instructions are provided.
However, the exact technique depends on testicular location and anatomy.
How Long Does Orchiopexy Surgery Take?
Operating time varies according to the location of the testicle and the complexity of the procedure.
For example, a straightforward inguinal orchiopexy may be shorter than a complex laparoscopic operation.
Additionally, anesthesia and recovery-room observation add to the total hospital time.
Therefore, caregivers should ask the surgical team for an individualized estimate.

Why Are Pediatric Surgical Instruments Important?
Orchiopexy involves small anatomical structures, including testicular vessels and the vas deferens.
Therefore, surgeons require appropriately sized instruments for careful tissue handling.
Furthermore, laparoscopic equipment must match the child’s size and the selected technique.
Consequently, hospitals should verify compatibility and approved intended uses before surgery.
Potential Benefits of Undescended Testis Surgery
1. Improved Testicular Position
Orchiopexy places a viable testicle into the scrotum. Consequently, the testicle becomes easier to examine.
2. Protection of Future Fertility Potential
Early surgery may help preserve the testicle’s future reproductive potential. However, it cannot guarantee normal fertility.
3. Easier Testicular Examination
A scrotal testicle is easier to examine during later medical assessments.
4. Reduced Long-Term Risk Compared With Delayed Treatment
Early correction may reduce some long-term risks. Nevertheless, the risk of testicular cancer remains higher than in individuals without cryptorchidism.
5. Correction of Associated Hernia
The surgeon may address an associated inguinal hernia during the operation when appropriate.
Risks and Complications of Orchiopexy Surgery
Although orchiopexy is an established procedure, complications can occur.
For example, some patients experience swelling, bruising, or wound infection.
Possible complications include:
- Postoperative pain
- Bleeding
- Swelling or bruising
- Wound infection
- Testicular atrophy
- Reduced testicular blood supply
- Injury to the vas deferens
- Testicular re-ascent
- Persistent abnormal testicular position
- Hernia-related complications
- Need for revision surgery
- Anesthesia-related complications
Furthermore, the risk varies according to testicular position and the selected technique.
Therefore, caregivers should discuss procedure-specific risks with the pediatric surgeon.
What Is Testicular Atrophy?
Testicular atrophy means the testicle becomes smaller or loses tissue function.
Sometimes, reduced blood supply after a complex operation contributes to this complication.
Therefore, surgeons assess blood supply carefully during treatment and follow-up.
Recovery After Undescended Testis Surgery
Recovery depends on the surgical approach and the child’s overall health.
Initially, mild swelling, bruising, and discomfort may occur.
However, these symptoms often improve during the following days.
Furthermore, many uncomplicated procedures allow discharge on the same day.
Nevertheless, complex cases may require additional observation or a longer recovery period.
Postoperative Care After Orchiopexy
Appropriate postoperative care supports healing and helps identify complications.
- Give prescribed medicines as directed
- Follow wound-cleaning instructions
- Keep dressings as instructed
- Avoid unnecessary pressure on the operative area
- Follow bathing restrictions
- Follow activity limitations
- Monitor for fever or worsening swelling
- Attend scheduled follow-up visits
- Ask the surgeon when normal play can resume
Additionally, caregivers should avoid applying unapproved creams or medicines to the wound.
How Long Does Recovery Take?
Initial recovery often occurs over several days to weeks.
However, return to active play, sports, or other activities depends on the operation and surgeon’s instructions.
Therefore, caregivers should follow the individualized recovery plan.
Can an Undescended Testis Return After Surgery?
Orchiopexy aims to keep the testicle in the scrotum.
However, re-ascent can occur in a small proportion of patients.
Consequently, follow-up examinations help confirm that the testicle remains in a suitable position.
Does Orchiopexy Improve Fertility?
Early orchiopexy may improve the chances of preserving future fertility potential.
However, fertility outcomes depend on whether one or both testicles are affected and the underlying testicular development.
Furthermore, surgery cannot fully reverse every change that occurred before treatment.
Does Surgery Eliminate Testicular Cancer Risk?
No. A history of undescended testis remains associated with an increased risk of testicular cancer.
However, early correction may reduce the risk compared with delayed surgery.
Furthermore, placing the testicle in the scrotum makes later examination easier.
Therefore, appropriate education and follow-up remain important.
Why Is Long-Term Follow-Up Important?
Follow-up helps assess testicular position, size, and development.
Additionally, some patients may need later review during adolescence.
Therefore, clinicians should explain future testicular health considerations and appropriate self-examination when the patient is old enough.
Warning Signs After Undescended Testis Surgery
Caregivers should contact the surgical team if concerning symptoms develop.
- Fever
- Severe or worsening pain
- Increasing scrotal swelling
- Persistent bleeding
- Foul-smelling wound discharge
- Increasing redness
- Wound separation
- Persistent vomiting
- Difficulty passing urine
- Sudden severe groin or scrotal pain
Importantly, sudden severe scrotal pain or rapidly worsening swelling requires urgent medical assessment.
