Orchiopexy for Undescended Testicle: Best Age, Surgery Steps, Recovery, and Long-Term Risks

An undescended testicle can be worrying for parents, especially when a doctor says that surgery may be needed. The good news is that orchiopexy for an undescended testicle is a common and well-established operation. In most children, it is a planned procedure, not an emergency, and the goal is simple: move the testicle into the scrotum and secure it there.

The timing, however, matters. Many parents are told to “wait and watch” in the first few months after birth, and that is often reasonable. But after a certain age, waiting too long may increase the risk of fertility problems, testicular shrinkage, injury, and difficulty detecting testicular cancer later in life. Current guidance generally supports referral if the testicle has not descended by about 6 months of age, with surgery usually recommended during infancy or early toddlerhood. The American Urological Association states that imaging is not recommended before referral and that orchiopexy is the most successful treatment for moving the testicle into the scrotum. (AUAA Journals)

This article explains what orchiopexy means, the best age for surgery, what happens during the operation, what recovery looks like, and what parents should know about long-term risks after orchiopexy.

An undescended testicle, also called cryptorchidism, means that one or both testicles have not moved down into the scrotum as expected. During pregnancy, the testicles usually develop inside the baby’s abdomen and then move down through the groin into the scrotum before birth. Sometimes this movement does not complete before the baby is born.

The main sign is that the scrotum looks empty or partly empty, or the doctor cannot feel one or both testicles in the scrotal sac. The National Health Service notes that undescended testicles are usually found during the newborn physical examination, although parents may notice later that only one testicle can be felt.(nhs.uk)

Undescended testicles are more common in premature babies and babies with low birth weight. StatPearls notes that cryptorchidism occurs in about 3 percent of full-term male infants and may be seen in up to 30 percent of premature male newborns.(NCBI)

In many babies, the testicle comes down on its own during the first few months of life. The National Health Service says undescended testicles often move into the scrotum in the first 12 weeks after birth. (nhs.uk) But if the testicle is still not in the scrotum after about 6 months, spontaneous descent becomes much less likely, and a specialist evaluation is usually needed.

Orchiopexy, also called orchidopexy, is a surgical procedure used to move an undescended testicle into the scrotum and fix it in place. The word is often searched in different spellings, including orchiopexy, orchidopexy, undescended testicle surgery, and cryptorchidism surgery.

The procedure is usually performed by a pediatric urologist or pediatric surgeon. It is done under general anesthesia, which means the child is asleep and does not feel pain during surgery. Cleveland Clinic explains that during orchiopexy for an undescended testicle, the surgeon makes a small incision in the groin or scrotum, locates the testicle and spermatic cord, repairs an associated hernia if present, creates a small pocket in the scrotum, and places the testicle in that pocket. (Cleveland Clinic)

In most children, orchiopexy is a one-day procedure. The child usually goes home the same day after a period of monitoring in the recovery area. Cleveland Clinic notes that orchiopexy takes about an hour in most cases and is usually an outpatient procedure.(Cleveland Clinic)

The most important question parents ask is: What is the best age for orchiopexy?

In simple terms, if the testicle has not descended by around 6 months of age, the child should be evaluated by a specialist. Surgery is commonly planned between 6 and 18 months of age, and many specialists prefer completing it around 1 year of age when possible.

The American Urological Association guideline emphasizes referral by 6 months of age and supports orchiopexy as the preferred treatment.(AUAA Journals) European guidance also supports early treatment, with surgery by 18 months at the latest to reduce possible long-term consequences for fertility potential and cancer risk. (PubMed) The National Health Service gives similar parent-friendly guidance, stating that surgery is usually done when the child is around 1 year old.(nhs.uk)

This timing is not just about appearance. The testicle is designed to sit in the scrotum, where the temperature is lower than inside the abdomen or groin. If the testicle remains in a warmer location for too long, its development may be affected. Earlier placement into the scrotum may help protect fertility potential and makes future examination easier.

If a baby is born with an undescended testicle, parents may wonder why surgery is not done immediately. The reason is that many testicles descend naturally during the first few months of life. StatPearls notes that about 80 percent of undescended testes seen at birth descend by 3 months.(NCBI)

That is why doctors usually monitor the baby during early checkups. However, if the testicle is still not in the scrotum after 4 to 6 months, especially if it cannot be felt, referral should not be delayed. The National Health Service says that if one testicle is affected and has not moved into the scrotum within 4 to 5 months, the child is usually referred to a specialist; if both testicles are affected, referral may happen sooner.(nhs.uk)

The practical message for parents is this: a short period of observation in early infancy is normal, but waiting year after year is not advisable.

Orchiopexy is not done only for cosmetic reasons. Moving the testicle into the scrotum may help reduce several risks.

First, it may help protect future fertility. The testicle needs the cooler environment of the scrotum for normal sperm-producing cell development. The risk is higher when both testicles are undescended, when the testicle is located higher in the abdomen, or when surgery is delayed.

Second, orchiopexy makes testicular examination easier later in life. A testicle that remains in the abdomen or groin is harder to examine. Once the testicle is in the scrotum, doctors can monitor its size and position, and the person can learn testicular self-examination after puberty.

Third, surgery may reduce the risk of trauma. HealthLink BC explains that a testicle in the groin area has a higher risk of injury from sports, seat belts, or direct pressure.(healthlinkbc.ca)

Fourth, orchiopexy can treat an associated hernia. Many boys with an undescended testicle also have a patent processus vaginalis, which is related to an indirect inguinal hernia. Cleveland Clinic notes that hernia repair may be performed during orchiopexy when needed.(Cleveland Clinic)

Not always immediately, but a testicle that remains undescended after early infancy usually needs treatment. If the testicle descends naturally during the first few months and stays in the scrotum, surgery may not be needed. If it remains outside the scrotum, orchiopexy is usually recommended.

There is also an important difference between an undescended testicle and a retractile testicle. A retractile testicle can move back and forth between the scrotum and groin because of an active muscle reflex. It can usually be brought down into the scrotum during examination and may stay there temporarily. A true undescended testicle cannot be brought down properly or does not stay in the scrotum.

Parents should not try to make this distinction at home. A pediatrician, pediatric surgeon, or pediatric urologist should examine the child. Cleveland Clinic notes that a retractile testicle can sometimes become an ascending or undescended testicle later, which is why regular follow-up is important.(Cleveland Clinic)

Many parents expect an ultrasound before surgery, especially if the testicle cannot be felt. Surprisingly, routine imaging is often not recommended before specialist referral. The American Urological Association guideline states that imaging is not recommended before referral for cryptorchidism.  (AUAA Journals)

The reason is that ultrasound may not reliably locate a non-palpable testicle, especially if it is inside the abdomen. A skilled physical examination by a specialist is often more useful. If the testicle cannot be felt, the surgeon may use diagnostic laparoscopy, a minimally invasive procedure using a small camera, to locate the testicle during surgery.

The exact surgical approach depends on where the testicle is located. A low undescended testicle near the scrotum is usually easier to repair than a testicle located high in the groin or abdomen.

For a palpable undescended testicle, the surgeon usually makes a small incision in the groin. The testicle is carefully freed from surrounding tissues while protecting the spermatic cord and blood vessels. If a hernia sac is present, it is repaired. The surgeon then creates a small pouch in the scrotum and brings the testicle down into that pouch. The testicle is secured so that it stays in the correct position.

For a non-palpable testicle, especially one suspected to be in the abdomen, laparoscopy may be used. HealthLink BC explains that orchiopexy may be done through incisions in the scrotum, groin, or abdomen, and laparoscopy may be used when the testicle is high in the inguinal canal or inside the abdomen. (healthlinkbc.ca)

Sometimes, if the testicle is very high and the blood vessels are too short, surgery may need to be done in stages. HealthLink BC notes that some abdominal testicles may require two separate operations several months apart. (healthlinkbc.ca)

In rare cases, the surgeon may find that the testicle is very small, poorly developed, or not viable. In such situations, removal may be considered, depending on the child’s age, the appearance of the testicle, and whether the other testicle is normal.

Most straightforward orchiopexy procedures take about one hour, although the total hospital time is longer because of preparation, anesthesia, recovery, and discharge monitoring. Cleveland Clinic notes that children are usually monitored in recovery until it is safe to go home, often around two hours after the procedure.(Cleveland Clinic)

More complex cases, such as abdominal testicles or repeat surgery, may take longer. Parents should ask the surgeon what type of orchiopexy is expected: standard groin orchiopexy, scrotal orchiopexy, laparoscopic orchiopexy, or staged orchiopexy.

Most children recover well after orchiopexy. Some sleep more than usual on the day of surgery. Mild nausea or vomiting can occur because of anesthesia. Pain is usually manageable with medicines recommended by the surgeon.

Cleveland Clinic states that pain or discomfort may last a few days to a week, and stitches usually dissolve in about two weeks. Many children can return to school or daycare within three to five days, depending on comfort level and the surgeon’s advice. (Cleveland Clinic)

Parents should expect some swelling, bruising, or tenderness around the groin or scrotum. This usually improves gradually. The incision should be kept clean and dry according to the hospital’s instructions. Some surgeons allow sponge bathing or showering after a certain period, while others ask parents to avoid bathing for several days.

For pain relief, doctors commonly recommend child-safe doses of medicines such as acetaminophen or ibuprofen, but parents should follow the surgeon’s specific instructions. South Tees Hospitals advises regular pain relief such as paracetamol and ibuprofen for the first two days after surgery, followed by use as needed if the child is improving.(South Tees NHS Trust)

Even if the child feels better quickly, rough activity should be limited. This is important because the testicle needs time to heal in its new position.

Cleveland Clinic advises avoiding sports and rough physical activity for at least two weeks after orchiopexy, including activities such as jumping, sprinting, tumbling, and straddling toys like bicycles, swings, seesaws, or rocking horses. (Cleveland Clinic) HealthLink BC gives similar advice, recommending avoidance of games, sports, rough play, bike riding, and activities that could injure the genital area for at least two weeks. (healthlinkbc.ca)

Some hospitals recommend a longer restriction period, especially after more complex surgery. Cambridge University Hospitals, for example, advises avoiding sports, cycling, and climbing for approximately six to ten weeks after undescended testis surgery. (Cambridge University Hospitals) Because advice varies by procedure and surgeon, parents should follow the discharge instructions given for their child.

Parents should contact the surgeon or hospital if the child develops concerning symptoms after surgery. Warning signs include fever, increasing redness, heavy bleeding, pus, foul-smelling drainage, worsening swelling, severe pain that does not improve with medicine, repeated vomiting, or inability to pass urine.

Cleveland Clinic specifically advises calling a healthcare provider for heavy bleeding, pus or foul smell at the incision site, fever, increased pain, or swelling after orchiopexy. (Cleveland Clinic)

A follow-up visit is usually scheduled after surgery. Cleveland Clinic notes that follow-up may occur around two weeks after the operation, with another check two to three months later. (Cleveland Clinic) HealthLink BC also notes that the doctor usually performs a follow-up examination within two to three months. (healthlinkbc.ca)

Orchiopexy is generally considered safe, but no surgery is risk-free. Possible complications include bleeding, infection, swelling, bruising, hematoma, wound problems, reaction to anesthesia, and scarring. Cleveland Clinic lists infection, hematoma, swelling, bruising, scarring, and anesthesia reactions among possible risks. (Cleveland Clinic)

More specific complications include damage to the vas deferens, which carries sperm, or injury to the blood supply of the testicle. If the blood supply is affected, the testicle may shrink, a condition called testicular atrophy. HealthLink BC lists infection, bleeding or blood clots, damage to the vas deferens or blood supply, testicular shrinkage, and re-ascent of the testicle as possible complications. (healthlinkbc.ca)

Another possible issue is that the testicle may move back up out of the scrotum after surgery. This is uncommon, but if it happens, another surgery may be needed. Cleveland Clinic notes that reascending testicle after orchiopexy is rare but may require additional surgery. (Cleveland Clinic)

One of the biggest long-term concerns is fertility. Orchiopexy improves the position of the testicle and may help protect fertility potential, but it does not always make the testicle completely normal. Some damage may have occurred before surgery, especially if the testicle was high, both testicles were affected, or treatment was delayed.

The risk of fertility problems is usually lower when only one testicle was undescended and the other testicle is normal. The risk is higher when both testicles were undescended, especially if they were not corrected early. A guideline comparison review notes that orchiopexy between 6 and 18 months is recommended to protect fertility potential and reduce malignant changes, and that infertility risk is higher in bilateral undescended testes, intra-abdominal testes, and delayed orchiopexy. (PMC)

Parents should understand this in a balanced way. Most boys with one corrected undescended testicle and a normal opposite testicle can do well. But orchiopexy is still important because it gives the testicle the best chance to develop in the right location and allows easier monitoring as the child grows.

An undescended testicle is associated with a higher lifetime risk of testicular cancer. Orchiopexy reduces some risk when done early and, importantly, makes the testicle easier to examine. However, surgery does not remove the risk completely.

Cleveland Clinic explains that children with undescended testicles may still have a slightly increased risk of testicular cancer, but earlier treatment decreases that risk. (Cleveland Clinic) A review published in The Journal of Urology reported that the relative risk of testicular cancer in cryptorchidism is increased and that patients who undergo orchiopexy after age 12 years or never undergo orchiopexy are more likely to have testicular cancer than those who have prepubertal orchiopexy. (PubMed)

This is why long-term awareness matters. Boys who had orchiopexy should be taught testicular self-examination after puberty and should report any lump, swelling, heaviness, or change in testicle size to a doctor. Cambridge University Hospitals advises regular monthly testicular self-examination from puberty onward for boys who have had surgery for undescended testes. (Cambridge University Hospitals)

Most orchiopexy surgeries are successful, especially when the testicle is low and palpable. HealthLink BC states that the outcome is usually good and that the testicle is moved into the scrotum in almost all who need the treatment, although success depends on the testicle’s location. (healthlinkbc.ca)

Failure can happen if the testicle re-ascends, shrinks, or cannot be positioned safely because of short blood vessels. A PubMed-indexed study of primary orchiopexy reported a low repeat orchiopexy rate, with a primary failure rate of 1.6 percent over 18 years. (PubMed)

Even after successful surgery, follow-up is important. Parents should attend the postoperative visits and continue routine pediatric checkups to confirm that the testicle remains in the scrotum and grows appropriately.

Before surgery, parents may feel more comfortable if they ask practical questions such as:

What type of orchiopexy does my child need?

Can the testicle be felt, or is it non-palpable?

Will laparoscopy be needed?

Is there a hernia that may need repair?

Is this likely to be a one-stage or two-stage surgery?

What pain medicine should be used after surgery?

When can my child return to school or daycare?

How long should we avoid cycling, sports, swimming, and rough play?

When is the follow-up visit?

What symptoms should make us call the hospital?

These questions help parents understand the plan and avoid confusion after discharge.

Although orchiopexy is ideally performed in infancy or early toddlerhood, some children are diagnosed later. This can happen if the testicle was missed earlier, if it was retractile and later became ascending, or if medical access was delayed.

Older children and teenagers should still be evaluated. The treatment decision may depend on the testicle’s size, location, appearance, and the condition of the other testicle. In postpubertal males with a long-standing undescended testicle, the surgeon may discuss different options, including orchiopexy or removal in selected cases, because cancer risk and fertility potential are different after puberty. The Journal of Urology review notes that management may differ in postpubertal males and that orchiectomy may be considered in some healthy patients with cryptorchidism between ages 12 and 50 years. (PubMed)

This is one reason early treatment is preferred. It is usually simpler, safer, and more protective when done in the recommended age window.

Orchiopexy for an undescended testicle is a common operation with a high success rate, but timing is important. Many undescended testicles come down naturally in the first few months after birth. If the testicle has not descended by around 6 months, parents should not keep waiting without specialist advice.

The best age for orchiopexy is usually after 6 months and before 12 to 18 months, depending on the child’s condition and the surgeon’s recommendation. Surgery is typically done under general anesthesia, often as a day-care procedure, and most children recover within days, although rough play and cycling may need to be avoided for longer.

Orchiopexy can improve testicle position, make examination easier, reduce injury risk, and may help protect fertility potential. It may also reduce but does not completely remove the long-term risk of testicular cancer. For that reason, boys who have had orchiopexy should continue regular follow-up during childhood and learn testicular self-examination after puberty.

For parents, the most important step is simple: if one or both testicles are not clearly in the scrotum after early infancy, get a pediatric urology or pediatric surgery opinion. Timely evaluation can make a meaningful difference in long-term health.
