Testicle pain after a groin hernia repair is common, because the operation happens right beside the cord that carries the testicle’s blood vessels, its nerves and the sperm tube. The cause usually depends on timing. Early pain is mostly healing tissue, while pain that lingers for months usually involves nerves rather than the testicle itself. One uncommon cause, a testicle losing its blood supply, needs prompt attention, so knowing which kind of pain you have matters more than how much it hurts. Lasting pain has effective treatments, including some for men whose pain no medicine has touched.
What Surgery Does Near the Testicle
An inguinal hernia pushes through the inguinal canal, the same channel the spermatic cord runs through on its way to the testicle. The cord carries the testicle’s artery, a web of veins, the sperm tube and small nerves. Several groin nerves run through or beside the canal, including one whose genital branch supplies feeling to the scrotum.1PubMed. Testicular pain after inguinal hernia repair: an approach to resection of the genital branch of genitofemoral nerve So an irritated groin nerve can send pain to the testicle even when the testicle itself is healthy. Nerves report pain to the area they supply, not to the spot where they are hurt, so a nerve pinched in scar can make a healthy testicle ache. It is also why a normal scan doesn’t mean the pain is imaginary.
Most hernia repairs today leave a mesh in place, a flat sheet of plastic netting that scar tissue grows into to reinforce the wall. In open repair, one cut in the groin lets the surgeon place the mesh in front of the muscle. Keyhole repair uses several small cuts and places the mesh from inside, behind the belly wall, where it overlaps the cord.2SAGES. Robotic Spermatic Cord Lysis for Treatment of Post-Operative Chronic Testicular Pain after Laparoscopic TEP Inguinal Hernia Repair with Mesh – SAGES Abstract Archives Either way, the cord, its veins and its nerves sit in or beside the area that heals around the mesh.
Pain and Swelling in the First Weeks
Scrotal swelling, wound bruising, fluid collections and bleeding into the scrotum and penis are all known early after-effects of the operation.3PubMed Central. Massive penoscrotal haematoma following inguinal hernia repair: a case report Bleeding that tracks down into the scrotum and penis is one of the most common complications.4PubMed Central. Massive penoscrotal haematoma following inguinal hernia repair: a case report Dark bruising spreading into the scrotum a few days after surgery is usually not a sign that something has gone badly wrong. It usually settles with rest and scrotal support.5PubMed Central. Massive penoscrotal haematoma following inguinal hernia repair: a case report
A typical course is soreness and swelling that are worst in the first few days. Swelling and tenderness then ease steadily over the next couple of weeks. Pain that keeps getting worse instead of better is the thing to report.
A fluid pocket can form where the hernia sac was, especially after large hernias.6PubMed. Different methods of managing the distal hernia sac to prevent seroma after laparoscopic repair of large indirect inguinal hernias: a real-world study The lump can feel like a returning hernia, but an ultrasound can tell fluid from a recurrent hernia.7Journal of Clinical Ultrasound. Scrotal sonography: A valuable tool in the evaluation of complications following inguinal hernia repair
To care for an aching, swollen scrotum, wear snug briefs or a scrotal support so the testicles don’t hang. Rest, and avoid heavy lifting for as long as your surgeon advises. A wrapped cold pack for short spells can ease swelling. Early on, take the pain relief your surgeon recommended at regular intervals rather than waiting for the pain to build.
Mild swelling that eases day by day is expected. A scrotum that keeps enlarging after the first few days, or becomes tense and shiny, deserves a call to the surgical team. A rapidly growing, tight swelling can mean ongoing bleeding into the tissue, which sometimes needs drainage or a closer look.
When the Testicle Loses Blood Supply
Loss of blood supply to the testicle is a rare complication of hernia repair.8PubMed Central. Testicular ischemia after inguinal hernia repair It usually comes from clotting in the web of veins in the cord, not from a cut artery.9PubMed Central. Orchiectomy as a result of ischemic orchitis after laparoscopic inguinal hernia repair: case report of a rare complication10The Canadian Journal of Urology. Testicular infarction as a sequela of inguinal hernia repair The testicle gets backup blood from several other arteries, which is why cutting the main one seldom kills it.11PubMed Central. Orchiectomy as a result of ischemic orchitis after laparoscopic inguinal hernia repair: case report of a rare complication Burning away the hernia sac, extensive handling of the cord, pulling the testicle out of the scrotum and a groin blood clot can all injure those veins.12The Canadian Journal of Urology. Testicular infarction as a sequela of inguinal hernia repair It is therefore more likely after repairs of large or difficult hernias that need more work around the cord.
The warning signs call for a same-day call to your surgeon or a trip to emergency:
- The testicle itself becomes hard, very swollen and exquisitely tender rather than just bruised.
- Pain worsens over the first days instead of easing.
- You have fever, or redness and heat over the scrotum.
- The testicle feels higher or a different shape than before.
You can’t safely tell ordinary bruising from a blood-supply problem by feel alone, so a scan settles it. An ultrasound with blood-flow imaging (Doppler) can show whether blood is reaching the testicle.13Journal of Clinical Ultrasound. Scrotal sonography: A valuable tool in the evaluation of complications following inguinal hernia repair14PubMed. Testicular infarction becoming apparent after hernia reduction Among men scanned for scrotal pain or swelling after repair, a few had testicles with no blood flow, while most had only fluid collections.15Wiley Online Library / Journal of Clinical Ultrasound. Scrotal sonography: A valuable tool in the evaluation of complications following inguinal hernia repair
This problem typically shows itself within the first days to couple of weeks after surgery, not months later. A testicle can shrink permanently if circulation stays poor, and in some cases the testicle dies and has to be removed.16PubMed Central. Orchiectomy as a result of ischemic orchitis after laparoscopic inguinal hernia repair: case report of a rare complication17PubMed.

Pain That Lasts for Months
Long-lasting pain after hernia repair usually comes from a neuroma, a tangled knot of healing nerve, on one of three groin nerves.18PubMed. Testicular pain after inguinal hernia repair: an approach to resection of the genital branch of genitofemoral nerve When the pain is mainly in the testicle, the genital branch of the genitofemoral nerve is the first suspect.19PubMed. Testicular pain after inguinal hernia repair: an approach to resection of the genital branch of genitofemoral nerve
When a nerve is cut, stretched or crushed during surgery, its fibers try to regrow and can form a knot instead of reconnecting neatly. That knot fires pain signals on its own and reacts strongly to pressure or movement, so a small area can hurt out of proportion to its size.
Mesh can trap and pull on nerves too. In mesh removed from patients, nerves had grown into the netting in 9 out of 10 samples.20International Journal of Clinical Medicine. Mesh-Related SIN Syndrome. A Surreptitious Irreversible Neuralgia and Its Morphologic Background in the Etiology of Post-Herniorrhaphy Pain Mesh can fold, shift and stretch nerves after surgery.21International Journal of Clinical Medicine. Mesh-Related SIN Syndrome. A Surreptitious Irreversible Neuralgia and Its Morphologic Background in the Etiology of Post-Herniorrhaphy Pain Mesh from men with pain contained far more nerves than mesh from men without pain.22PubMed. A mechanism of mesh-related post-herniorrhaphy neuralgia Scar binding the mesh to the cord can cause a tugging ache running down to the testicle.23SAGES. Robotic Spermatic Cord Lysis for Treatment of Post-Operative Chronic Testicular Pain after Laparoscopic TEP Inguinal Hernia Repair with Mesh – SAGES Abstract Archives Men describe a pulling or dragging from groin into the testicle, which may worsen with stretching, exercise or standing a long time.
Nerve pain often burns, stabs or shoots, or feels like an electric jolt. Light touch, tight clothing, walking or sitting can set it off, and numbness or odd sensation in the groin skin often comes with it. Healing pain tends to be a dull ache that fades steadily, while nerve pain tends to persist or flare.
The skin heals within weeks, but nerves regrow slowly and scar tissue keeps remodeling for months, so pain can persist after the scar looks fine. Some men feel nothing unusual at first and then notice pain building weeks or months later as scar tightens around a nerve or the mesh. Pain that has lasted several months is not a sign you are healing slowly, and it is a reason to be assessed instead of waiting indefinitely.
About 2 in 100 men have pain on ejaculation after hernia repair.24PubMed Central. An overlooked complication of the inguinal hernia repair: Dysejaculation It was slightly more common after keyhole repair than after open repair.25PubMed Central.

Who Is More Likely to Have Lasting Pain
Younger age, pain before surgery, strong pain soon after surgery, other complications and a repeat repair on the same side all raise the risk of long-lasting pain.26Clinical Pain Advisor. Risk Factors Identified for Persistent Pain After Inguinal Hernia Surgery27PubMed. Incidence and predictors of chronic pain after inguinal hernia surgery: a systematic review and meta-analysis Small hernia openings under 3 cm were linked to slightly higher risk.28PubMed. Incidence and predictors of chronic pain after inguinal hernia surgery: a systematic review and meta-analysis Having pain before surgery is one of the clearer signals, so mentioning an existing ache at your pre-operative visit lets the team plan for it.
A repeat repair goes through old scar, where nerves are harder to see and more likely to be caught or cut. If you’re facing one, ask how your surgeon protects the nerves.
Pain that stays severe in the first week despite the recommended pain relief is a recognized warning sign for pain that lingers. Telling your surgeon early allows adjustment of medication and a check for fluid, bleeding or other complications that could be treated.
Surgery type also plays a part. Overall groin pain during activity is less after keyhole repair,29PubMed. Testicular functions, chronic groin pain, and quality of life after laparoscopic and open mesh repair of inguinal hernia: a prospective randomized controlled trial and early pain in the first week is greater after open repair.30PubMed.

Laparoscopic extraperitoneal inguinal hernia repair versus open mesh repair: long-term follow-up of a randomized controlled trial Most men recover completely either way: 89% after keyhole and 95% after open repair in that trial.32PubMed.

How Doctors Find the Cause
Scrotal ultrasound can spot loss of blood flow, fluid pockets and a recurring hernia.33Journal of Clinical Ultrasound. Scrotal sonography: A valuable tool in the evaluation of complications following inguinal hernia repair It is usually the first test for a swollen or very painful testicle after repair.
The exam comes alongside it. The doctor looks at the scar and scrotum, feels both testicles for size, firmness and tenderness, and compares the painful side with the other. They press along the cord and groin to find out whether the tenderness comes from the testicle itself or from tissue higher up. They may also check for a bulge when you cough or stand, which helps show whether the hernia has returned.
Nerve pain is pinned down mostly by pattern. The doctor maps where the skin feels numb or oversensitive, and pressing along the scar may reproduce the pain. A numbing injection near a nerve that brings relief points to that nerve. A normal scan with ongoing pain is consistent with a nerve cause, alongside these other clues.
At the visit, it helps to say when the pain started relative to surgery and whether it’s getting better or worse. Describe whether it burns, shoots or aches, and what triggers it. Mention any numbness, swelling or pain with ejaculation, whether you had pain before surgery, and which repair you had.
Treatments for Pain That Won’t Go Away
Guidelines advise trying pain treatment without surgery first and waiting at least a year after the repair before operating.34PubMed. International guidelines for prevention and management of post-operative chronic pain following inguinal hernia surgery First-line options include regular anti-inflammatory or nerve-pain medicines prescribed by a doctor, and numbing or steroid injections near the suspected nerve. If simple measures fail, a pain clinic is the next step. Pulsed radiofrequency, which uses electrical pulses through a needle to calm a nerve, gave months of relief in reported cases,35PubMed Central. Pulsed radiofrequency for chronic post-herniorrhaphy inguinal pain: A road less traveled but the evidence is early and a placebo effect hasn’t been ruled out.36PubMed Central. Pulsed Radiofrequency Ablation for Orchialgia—A Literature Review
The wait makes sense because nerves and scar keep changing for many months, and pain that seems fixed at three months can fade on its own by a year. It also gives time for medicines and injections, which help some men enough to avoid an operation. Operating too soon risks cutting a nerve that might have recovered, leaving permanent numbness for little gain.
For pain that persists, surgery helps most men. Neurectomy, cutting the three groin nerves, improved pain in about 98% of men in pooled results.37PubMed Central. Impact of different neurectomy techniques on managing chronic pain after inguinal hernia repair: a meta-analysis and systematic review In one large group treated for testicle pain after repair, 99% improved and about two-thirds had their pain more than halved.38PubMed. Surgical management of chronic orchialgia after inguinal hernia repair Cutting just the genital nerve branch above the old scar relieved testicle pain in a small group.39PubMed. Testicular pain after inguinal hernia repair: an approach to resection of the genital branch of genitofemoral nerve
The surgeon reopens the groin, finds the nerves and cuts the painful ones, sometimes removing a section so that a neuroma cannot re-form. Because the nerve no longer carries sensation, you can expect numbness in the skin it supplied, usually in part of the groin, upper thigh or scrotum. The numbness is usually permanent, though it often becomes less noticeable over time.
Before nerve or mesh surgery, ask which nerves will be cut and whether the mesh will be removed. Ask how many of these operations the surgeon has done, and what happens if the pain doesn’t improve.
Removing the testicle is kept for rare cases with a damaged testicle that other treatment hasn’t helped.40PubMed Central. Successful treatment for patients with chronic orchialgia following inguinal hernia repair by means of meshoma removal, orchiectomy and triple-neurectomy Even then, after removal, only about 65% were free of testicle pain.41PubMed.

Effects on Fertility and Sex
Among men at a fertility clinic, those with a past hernia repair had poorer sperm than fertile men.42PubMed. Fertility of men following inguinal hernia repair The damage was greater when the testicle had shrunk after surgery.43PubMed. Fertility of men following inguinal hernia repair That finding concerns men already being seen for fertility problems, and it does not show that the surgery caused the poor sperm, since men who struggle to conceive may differ in other ways. Most men who have a hernia repair keep normal fertility. The concern is greatest when blood supply to the testicle was damaged or both sides were operated on.
A testicle that lost blood supply may shrink over weeks to months. It may stop making sperm, but the other side usually compensates, and one healthy testicle is usually enough for fertility. Hormone levels typically stay normal with one working testicle. Men planning children with a shrunken testicle or repairs on both sides can ask for a semen test.
Doctors may not ask about pain with ejaculation, so mention it specifically. It can relate to scar or nerves near the sperm tube.
