What Happens in Testicular Torsion Surgery: Detorsion, Orchiopexy and Fixing Both Sides

It is a little after midnight in an emergency department. A fifteen-year-old is sitting very still on the edge of a bed because moving makes the pain in his scrotum worse, and his father is asking the same question three different ways: is this really surgery, and does it really have to be now? The nurse has already paged the on-call urologist. Nobody is using the word “maybe.”

That urgency is the defining feature of testicular torsion surgery. Most operations come with a consultation, a second opinion, a date on a calendar. This one comes with a stopwatch, and the people explaining it are often doing so while wheeling the bed toward the operating room.

Here is what the surgeon is about to do, why the other side gets stitched too, what the next weeks look like, and where the popular assumptions about this operation go wrong.

Why testicular torsion surgery cannot wait

Testicular torsion is a twist of the spermatic cord, the bundle of blood vessels, nerves and the sperm-carrying tube that suspends each testicle inside the scrotum. Twist the cord and you pinch the vessels running through it. The veins collapse first, blood backs up, the testicle swells, and then the arterial supply fails. Tissue that is starved of oxygen begins to die.

Mayo Clinic describes the first six hours after pain begins as the window in which saving the testicle is most likely, with the odds falling steadily afterward and the risk of needing removal rising markedly once twelve hours have passed. Those hours are counted from the start of pain, not from arrival at the hospital, which is why emergency teams move quickly rather than waiting for every test to come back.

The condition is not common: Cleveland Clinic puts it at roughly 1 in 4,000 males under 25. But among the causes of a suddenly painful scrotum, it is the one that cannot safely be watched. An infection can be treated tomorrow. A twisted cord cannot.

Surgeons have a blunt phrase for this: torsion is diagnosed in the operating room. If the history and examination point strongly toward torsion, many teams will go to surgery on suspicion alone and use the operation itself to confirm what is happening. A Doppler ultrasound, a scan that shows blood moving through vessels, is often used when there is time and the picture is unclear, but Mayo Clinic notes that imaging should never delay treatment when the clinical suspicion is high.

Understanding that logic helps families who arrive expecting a diagnosis first and a treatment plan second. With torsion, the order is reversed on purpose.

What makes a spermatic cord twist in the first place?

Normally the testicle is anchored to the back wall of the scrotum by a fold of tissue, which keeps it from spinning. Some people are born without that anchor, or with a loose version of it, so the testicle hangs freely inside its covering like the clapper inside a bell. Doctors call this the bell clapper deformity. Cleveland Clinic and the NIH StatPearls reference both identify it as the main anatomical reason torsion happens, and StatPearls cites autopsy studies finding the variant in around 12 percent of males, usually on both sides.

That last detail matters later, because it is the reason surgeons stitch the second testicle.

The trigger for the actual twist is often unremarkable. Mayo Clinic lists vigorous activity, a minor injury to the groin, rapid growth during puberty and cold temperatures among the situations that precede torsion, and notes that it frequently happens during sleep. The cremaster muscle, a thin muscle that lifts the testicle in response to cold or touch, contracts and rotates a freely hanging testicle instead of simply raising it.

Age follows a two-peak pattern. The largest group is adolescents between about 12 and 18, according to Mayo Clinic, when testicular growth is fastest. A smaller peak occurs in newborns, sometimes before birth, where the mechanism is different: the whole testicle and its coverings rotate together because they have not yet fused to the scrotal wall.

None of this is caused by anything the patient did. Parents in the emergency department often ask whether a bike ride, a sports tackle or a late-night video game session is to blame. The honest answer is that the anatomy was set before birth, and the trigger could have been anything or nothing.

Who is taken straight to the operating room, and who is asked to wait

For someone with sudden, severe, one-sided scrotal pain and an examination that fits torsion, there is no waiting list. Confirmed or strongly suspected torsion means surgery as soon as an operating room and anesthetist are available, usually within the hour of the decision being made. Fasting rules that would normally delay a planned operation are managed rather than allowed to postpone it, because the risk from the twisted cord outweighs the risk of anesthesia on a full stomach.

A short list of situations looks different.

Intermittent torsion is the first. Some people describe repeated episodes of sharp testicular pain lasting minutes to an hour that resolve on their own. Mayo Clinic explains that this can be a testicle twisting and untwisting spontaneously, and that surgery to anchor it is often recommended to prevent a full torsion. In this case the operation is planned rather than emergency, and the person may indeed be asked to wait for a scheduled date.

The second is an uncertain diagnosis with reassuring findings. When pain has developed gradually over days, blood flow on ultrasound is normal and the examination suggests infection or inflammation of the epididymis, the coiled tube behind the testicle, the team may choose observation and treatment for infection instead. That is a judgment made by the examining clinician, not a reason for a patient to reassure themselves at home.

The third is newborn torsion, where the timing of surgery and whether to explore the other side are weighed case by case by pediatric surgeons, since the testicle is frequently already unsalvageable by the time it is noticed.

Finally, a testicle that has clearly been twisted for days will still usually be operated on, but the goal shifts from rescue to removal of dead tissue and protection of the other side.

What actually happens during testicular torsion surgery, step by step

The operation is done under general anesthesia, meaning the patient is fully asleep and pain-free. MedlinePlus describes the sequence, and it is shorter than most people imagine.

The surgeon makes a small cut in the scrotum, usually along the seam in the middle or across the affected side, and opens the thin coverings around the testicle. The twisted cord is now visible. The surgeon rotates the testicle in the direction that unwinds the cord, which can mean one or more full turns; StatPearls notes that torsion of 360 to 720 degrees is common.

Then comes the wait. The testicle, which may have looked dark purple or black, is wrapped in warm saline-soaked gauze for several minutes and watched. Pink returning to the tissue and bleeding from a tiny nick in the surface are signs that blood flow has resumed and the testicle is viable. If the color does not improve, the surgeon has to make a decision about removal, covered below.

If the testicle recovers, it is fixed in place with stitches to the inside wall of the scrotum. That is the orchiopexy, explained in the next section. The surgeon then repeats the fixation on the other side through the same incision or a second small one.

The scrotal skin is closed with dissolvable stitches. MedlinePlus lists the whole procedure as commonly taking well under an hour, though times vary with what is found.

A word about manual detorsion: before surgery, a doctor may try to untwist the testicle by hand through the skin, a maneuver Mayo Clinic describes as sometimes successful at relieving pain. It is a bridge, not a treatment. Surgery still follows to confirm the untwisting and anchor the testicle so it cannot happen again.

Orchiopexy for torsion: how the testicle is fixed in place

Orchiopexy is the surgical anchoring of a testicle to the scrotal wall so that it cannot rotate. The word is borrowed from a different operation, the one used to bring an undescended testicle down into the scrotum in young children. In torsion, the testicle is already where it belongs; the job is to stop it moving.

The surgeon places two or three fine, non-dissolving stitches between the tough outer coat of the testicle and the inner lining of the scrotum, typically at separate points so that the testicle is held at more than one angle. Some surgeons instead create a small pocket between layers of scrotal tissue and tuck the testicle inside, relying on scar tissue to hold it. Both approaches aim at the same result, and the choice depends on the surgeon’s training and what the tissues look like on the day.

Patients and parents sometimes worry that stitches through the testicle must damage it. The stitches pass through the thick fibrous capsule, not the sperm-producing tissue inside. Cleveland Clinic describes fixation as a routine part of torsion repair precisely because it carries little added risk while removing the mechanism for a repeat episode.

Once anchored, the testicle sits slightly differently than it did before, sometimes a little higher or turned a fraction, and the person may notice this in the first weeks. It is expected.

Fixation also changes the risk equation for the future. A testicle held by stitches or a tissue pocket has lost the free rotation that caused the problem. Recurrent torsion after orchiopexy is described in the medical literature as uncommon, though, as with any surgical repair, not impossible, which is why new pain after surgery is always taken seriously.

Why surgeons fix the healthy side too

The most frequently asked question after the operation is not about the testicle that was in trouble. It is about the other one. Why operate on a testicle that was fine?

The answer goes back to the bell clapper anatomy. Because the loose attachment is a developmental variant rather than an injury, it tends to be present on both sides. Cleveland Clinic and MedlinePlus both describe fixing the unaffected testicle as standard practice during torsion repair, and StatPearls reports that the variant is bilateral in the majority of people who have it.

Picture the alternative. A person who has already lost, or nearly lost, one testicle to torsion goes home with the other hanging freely on the same faulty anchor. A second episode on the remaining side would put fertility and hormone production at stake. The surgeon is already in the scrotum, under anesthesia, with the incision made. Adding a few stitches to the other side takes minutes and prevents a second emergency.

The other testicle is usually reached through the same midline incision or through a small matching cut on its own side. It is inspected, confirmed to be untwisted and healthy, and anchored in exactly the same way.

A handful of exceptions exist. In newborns, pediatric surgeons weigh the decision differently because the mechanism of torsion is different and the second testicle has usually already fused into place. In rare cases where the patient is critically unwell and every minute of anesthesia carries risk, a surgeon may defer the second side. Those are individual calls made in the operating room.

For most adolescents and adults, though, waking up with two sets of stitches is the expected outcome, and it is a sign the team was thinking about the next ten years, not just the next ten hours.

When the testicle cannot be saved: orchiectomy and what follows

Sometimes the untwisted testicle does not turn pink. The surgeon waits, warms it, watches, and the tissue stays dark. At that point the decision is to remove it, an operation called orchiectomy.

This is the outcome families fear most, and it is worth being clear about why it happens and why it is the right call when it does. Dead tissue left inside the scrotum cannot recover. It becomes a source of infection and prolonged pain, and there is a theoretical concern, discussed in StatPearls, that a damaged testicle releases proteins that trigger an immune reaction against the healthy side. Removing it protects the person, even though it feels like a loss.

The removal is done through the same incision. The cord is tied off above the dead testicle and the testicle is taken out. The healthy side is still anchored with an orchiopexy, which becomes even more important now that it is the only one.

How often this happens depends almost entirely on the clock. MedlinePlus states plainly that the testicle is more likely to be saved the sooner surgery is performed, and Mayo Clinic ties the rising chance of removal to delays beyond six to twelve hours. Beyond a day, rescue is unusual.

After orchiectomy, a person can choose, later, to have a testicular prosthesis placed, a soft implant that restores the appearance and feel of the scrotum. This is an elective, planned operation, usually offered once healing is complete and often deferred in teenagers until growth has finished. It is a personal decision with no medical urgency, and the treating team can discuss timing when the person is ready.

One functioning testicle is sufficient for normal hormone levels and, for most people, fertility, as the next sections explain.

Torsion treatment options at a glance

The choices in torsion are narrow, which is part of what makes it easier to explain than many operations. The table below sets out what each step is, when it is used and what it does and does not accomplish, drawing on descriptions from Mayo Clinic, MedlinePlus and Cleveland Clinic.

Step	What it is	When it is used	What it achieves	Limits
Manual detorsion	Untwisting the testicle by hand through the skin	Sometimes attempted while awaiting surgery	May restore blood flow and ease pain quickly	Not always possible; surgery still required to confirm and anchor
Surgical detorsion	Opening the scrotum and unwinding the cord	Every suspected torsion taken to surgery	Restores flow if tissue is still alive	Success depends on hours elapsed
Orchiopexy (affected side)	Stitching the testicle to the scrotal wall	When the testicle recovers after untwisting	Prevents re-twisting of that testicle	Small chance of recurrence; slight change in position
Orchiopexy (other side)	Anchoring the healthy testicle	Standard in adolescents and adults	Protects against future torsion of the remaining side	Adds a second set of stitches and some discomfort
Orchiectomy	Removal of a non-viable testicle	When the testicle does not recover in the operating room	Removes dead tissue; prevents infection	Loss of the testicle; prosthesis can be considered later
Observation	Monitoring without surgery	Only when the clinician has excluded torsion	Avoids an operation for infection or inflammation	Never appropriate for suspected torsion

What the table cannot show is that these steps are not really alternatives. Detorsion and fixation are one continuous operation, and orchiectomy is what happens when detorsion arrives too late. The only decision that belongs to the patient, and only after the emergency has passed, is whether to pursue a prosthesis.

Is testicular torsion surgery serious? Anesthesia, risks and what "serious" means

People searching this question usually mean two different things: is the operation dangerous, and is the condition dangerous. The answers pull in opposite directions.

The condition is serious because of what is at stake for the testicle. The operation itself is, in surgical terms, a minor procedure: a small incision in skin that heals well, no entry into the abdomen, short anesthesia time, and in most cases discharge the same day. MedlinePlus describes it as typically an outpatient operation.

That does not mean it is risk-free. Any general anesthetic carries a small risk of breathing difficulty, allergic reaction or nausea afterward, and the anesthetist will ask about prior anesthetics, medicines and family history for exactly that reason. Emergency surgery on someone who has recently eaten adds a modest risk of stomach contents entering the airway, which is why the team may ask precisely when the person last ate and adjust their technique.

Surgical risks specific to this operation, as listed by MedlinePlus and Mayo Clinic, include bleeding into the scrotum, wound infection, and, even after a successful untwisting, later shrinkage of the testicle because the hours without blood flow caused damage that only shows itself over months. There is also a small risk that a testicle judged viable in the operating room does not fully recover, and a small risk of torsion recurring despite fixation.

Pain relief after surgery is arranged by the team; the choice and timing of any medicine is theirs to make, and questions about it belong with the prescribing clinician.

So, is it serious? The operation is one of the more routine procedures a urologist performs. The reason everyone around the patient looks tense is not the surgery. It is the clock.

Testicular torsion recovery time: the first day, the first weeks

Most people wake up in a recovery area within an hour of the operation ending, with the scrotum supported by snug underwear or a supportive garment and a dressing over the incision. Cleveland Clinic and MedlinePlus both describe discharge home the same day as typical, once the person has passed urine, eaten something and has pain under control.

Walking is encouraged from the first day. Getting up to the bathroom, moving around the house and short slow walks are fine and help prevent stiffness and blood clots. What people are asked to avoid is anything that jolts or strains the scrotum: running, cycling, contact sports, heavy lifting and, for adolescents, physical education classes.

Swelling and bruising of the scrotum peak in the first two to three days and then fade. Ice packs wrapped in cloth, applied for short periods, and lying with the scrotum slightly elevated help, as MedlinePlus advises. Dissolvable stitches disappear on their own over a couple of weeks and can leave a little scab or thread that comes away in the shower.

Return to school or desk work is often possible within a few days once sitting is comfortable, with the exact timing set by how the person feels and what the surgeon advises. Sport and strenuous activity are usually deferred for several weeks; MedlinePlus advises following the surgeon’s specific clearance rather than a fixed calendar, and many teams review the wound and give the go-ahead at a follow-up visit.

A person who had a testicle removed follows the same path, though the emotional adjustment may take longer than the physical one.

Every one of these timelines is a typical range, not a promise. Healing depends on how long the testicle was twisted, whether both sides were operated on and how the individual’s body responds.

Fertility, hormones and the long view after torsion surgery

The second most common question after “why the other side” is “will he be able to have children.” It is often asked in a hallway, quietly, by a parent who does not want the teenager to hear.

Start with the reassuring physiology. Each testicle produces both sperm and testosterone, and a single healthy testicle is capable of doing both jobs for the whole body. Cleveland Clinic states that people who lose one testicle to torsion generally maintain normal hormone levels and can father children. The remaining testicle often enlarges slightly to compensate.

The picture is more nuanced for a testicle that was saved after a long period without blood flow. Damage to the sperm-producing tissue can occur even when the testicle survives, and StatPearls notes that reduced sperm counts and testicular shrinkage are recognized after torsion, with the risk increasing with the duration of twisting. Whether this translates into difficulty conceiving varies widely between individuals, and the healthy side usually compensates.

For adults who want certainty, a semen analysis some months after surgery can give a direct answer about sperm numbers and movement. This is a routine test arranged through a doctor, not an emergency, and the treating team can advise on timing once healing is complete. For adolescents, this conversation is usually deferred until it becomes relevant.

Testosterone production is rarely affected by losing one testicle, so puberty proceeds normally and there is no expected effect on voice, muscle, sexual function or mood. If a person has symptoms that concern them years later, hormone levels can be checked with a simple blood test.

The long-term follow-up, then, is modest: a wound check, a conversation about activity, and an open door for questions about fertility when the person is ready to ask them.

What people often get wrong about testicular torsion surgery

Several misunderstandings surface repeatedly in emergency departments and online forums, and some of them cost time that the testicle does not have.

“The pain eased, so it must have fixed itself.” Pain that suddenly stops after hours of severe torsion can mean the nerve has died along with the tissue, not that the cord has untwisted. Mayo Clinic specifically warns that resolving pain does not mean the danger has passed. Relief without treatment should prompt a hospital visit, not a return to bed.

“It happened during sport, so it was an injury.” Activity can trigger the twist, but the underlying cause is anatomical. Nobody needs to feel that a game or a fall was to blame.

“An ultrasound will tell us for sure.” Doppler ultrasound is useful, but it can miss torsion in early or partial cases. Surgeons will operate on strong clinical suspicion regardless of the scan.

“Losing a testicle means infertility or low testosterone.” One healthy testicle typically provides normal hormones and fertility, as Cleveland Clinic explains.

“Fixing the other side is overtreatment.” Because the loose anatomy is usually bilateral, anchoring the second testicle prevents the same emergency happening to the only one left.

“Once it is stitched, it can never twist again.” Recurrence after orchiopexy is uncommon, but new severe scrotal pain after surgery still needs urgent assessment.

“It only happens to teenagers.” Adolescence is the peak, but torsion occurs in newborns and adults too, and adults sometimes delay because they assume they are too old for it.

“Waiting for morning is fine.” This is the one that matters most. The clock runs from the onset of pain, and the difference between a 3 a.m. operation and a 9 a.m. one can be the difference between saving and removing the testicle.

Questions to ask your care team before and after the operation

Torsion rarely allows a leisurely conversation before surgery, but even five minutes with the surgeon or anesthetist is enough to ask what matters most. Afterward, there is more time, and the questions change.

Before surgery, useful questions include:

• How confident are you that this is torsion, and does anything in the examination or scan argue against it?
• Will you fix the other testicle as well, and if not, why?
• What will you do if the testicle does not recover after untwisting?
• Who will explain what was found once the operation is over?

Immediately after surgery, the questions become practical:

• Was the testicle saved, and how did it look when you untwisted it?
• How many hours had passed, and does that change what you expect for recovery?
• What should the wound look like over the next week, and what would worry you?
• How should pain and swelling be managed at home, and who do I contact if the plan is not working?
• When can he walk, sit for a full school day, shower, and return to sport?

At the follow-up visit, think longer term:

• Is there any sign the testicle is shrinking, and how would we know?
• Is a fertility check worth arranging, and when?
• If a testicle was removed, when could a prosthesis be considered and who would do it?
• What symptoms in the future would mean coming straight back?

Write the answers down or ask permission to record them. In an emergency, families remember the fear and forget the facts, and having the surgeon’s own words to return to makes the next weeks easier. Every one of these decisions, from pain relief to prosthesis timing, sits with the treating team, and the best outcome comes from asking rather than assuming.

When to call your doctor: red flags before and after testicular torsion surgery

Before any diagnosis, the rule is simple. Sudden, severe pain in one testicle, especially with swelling, nausea, vomiting or a testicle that sits higher than usual, is an emergency. Mayo Clinic advises going to an emergency department immediately rather than waiting to see whether it settles. The same applies to pain that comes and goes in sharp episodes, and to any scrotal pain in a baby or young child that comes with a firm, discolored or swollen scrotum.

After surgery, most days are quiet and uneventful. Call the surgical team or seek urgent care if you notice any of the following:

• Pain that suddenly worsens rather than steadily improving, or severe pain returning in either testicle, which could mean re-twisting.
• Fever, chills or feeling generally unwell.
• Redness spreading from the incision, warmth, or thick or foul-smelling discharge from the wound.
• Rapidly increasing swelling or a hard, tense scrotum, which can signal bleeding inside.
• The wound opening or bleeding that does not stop with gentle pressure.
• Difficulty passing urine, or blood in the urine that persists.
• Persistent vomiting that stops fluids or medicines staying down.

Mild bruising, some swelling for a week or two and tenderness when sitting are expected and do not need a call. Anything that feels wrong, or any new severe pain in the scrotum at any point in the future, does.

If in doubt, ring. Urology teams would far rather reassure a worried parent about normal bruising than hear about a re-twisted testicle a day too late. The judgment about whether something is serious belongs to the clinicians who know what was found in the operating room, and they can only make it if they are told.

Frequently asked questions

Is testicular torsion surgery serious?

The operation itself is a short, routine urological procedure through a small scrotal incision, usually done as a same-day case under general anesthesia. The seriousness lies in the condition: without prompt untwisting the testicle dies. Risks of surgery include bleeding, wound infection, anesthetic reactions and later shrinkage of a testicle that was without blood flow for a long time.

What is the testicular torsion recovery time after surgery?

Most people go home the same day, with swelling and bruising peaking over two to three days and fading over one to two weeks. School or desk work is often possible within a few days, while sport, running and heavy lifting are usually deferred for several weeks until the surgeon confirms healing. These are typical ranges, not promises, and depend on what was found.

How long after testicular torsion surgery can you walk?

Walking is encouraged from the first day, including getting up to the bathroom and short, gentle walks at home. Movement helps circulation and reduces stiffness. What is restricted is anything that jolts or strains the scrotum: running, cycling, contact sports and heavy lifting are paused until the surgical team gives clearance, often at a follow-up visit.

What does orchiopexy for torsion involve?

Orchiopexy is the anchoring of a testicle to the inner wall of the scrotum so it cannot rotate again. The surgeon places a few fine stitches between the tough outer capsule of the testicle and the scrotal lining, or tucks the testicle into a pocket of scrotal tissue. The stitches pass through the capsule, not the sperm-producing tissue inside.

Why is the other testicle also stitched during torsion surgery?

The bell clapper deformity, a loose attachment that lets the testicle spin freely, is usually present on both sides. Anchoring the healthy testicle during the same operation prevents a future torsion of the remaining side, which would put fertility and hormone production at risk. Cleveland Clinic and MedlinePlus describe fixing both sides as standard practice.

What is the testicular torsion time window for saving the testicle?

Mayo Clinic describes the first six hours from the onset of pain as the period of best chance, with the likelihood of saving the testicle falling steadily afterward and the chance of removal rising once twelve hours have passed. The clock starts when pain begins, not on arrival at hospital, which is why suspected torsion goes straight to surgery.

What happens if the testicle cannot be saved?

If the testicle does not regain color and blood flow after untwisting, it is removed in an operation called orchiectomy, because dead tissue causes infection and pain. The healthy side is still anchored. Later, once healing is complete, a soft testicular prosthesis can be placed as a planned, elective procedure if the person wishes.

Can you still have children after losing a testicle to torsion?

In most cases, yes. One healthy testicle produces enough sperm and testosterone for normal fertility and hormone levels, and it often enlarges slightly to compensate. A semen analysis arranged some months after surgery can give a direct answer for adults who want certainty. A saved testicle that was twisted for many hours may have reduced sperm production.

How long does it take to recover from a ruptured testicle?

A ruptured testicle is a different injury, a tear in the testicle’s outer capsule from direct trauma, repaired by surgery to remove damaged tissue and close the capsule. Recovery follows a similar pattern to torsion repair: home within a day or two, swelling settling over a couple of weeks, and sport deferred for several weeks under the surgeon’s guidance.

Can testicular torsion happen again after surgery?

Recurrence after orchiopexy is uncommon because the stitches or tissue pocket remove the free rotation that caused the twist. It is not impossible, however, and any new sudden severe pain in either testicle after surgery should be assessed urgently in an emergency department rather than watched at home.
