Lumbar spine problems can cause testicular pain, but L5-S1 is not the level most directly implicated. The nerve roots that supply sensation to the testicle arise primarily from the upper lumbar spine, around L1 and L2, not from the L5 or S1 roots. That said, the relationship between spinal disease and groin pain is more tangled than a simple one-nerve-one-symptom map suggests, and disc problems at multiple lumbar levels, including those lower down, have appeared alongside unexplained testicular pain in published case reports.
Why the Spine and the Testicle Share Nerve Wiring
The testicle’s sensory supply traces back to the genitofemoral nerve, which originates from the L1 and L2 nerve roots. This nerve travels downward through the psoas muscle in the lower abdomen, splits into two branches, and one of those branches follows the spermatic cord into the scrotum. When something irritates or compresses the nerve roots feeding into this pathway, the brain can interpret the signal as pain coming from the testicle itself, even though the actual problem is in the spine.
There is also a less direct route. The outer portion of a spinal disc is supplied by a small nerve called the sinuvertebral nerve, which is formed partly from the spinal nerve and partly from the sympathetic nervous system. Because the sympathetic chain runs alongside the lumbar spine and connects to multiple levels, irritation at one disc level can theoretically send pain signals through pathways that overlap with the nerves serving the groin and scrotum.1PubMed Central. Atypical manifestations of lumbar discogenic pain: a case of thigh and testicular pain associated with a high-intensity zone This crossover of sympathetic and somatic nerve fibers is one reason spinal problems can produce pain in areas that seem completely unrelated to the back.
Which Lumbar Levels Are Most Linked to Testicular Pain
The case reports in the medical literature overwhelmingly point to upper and mid-lumbar disc disease as the culprit when testicular pain has a spinal origin. L1-L2 and L3-L4 disc herniations show up repeatedly, which makes anatomical sense because the genitofemoral nerve branches off from L1-L2, and the L3 nerve root feeds into the psoas muscle. Compression or irritation of L3 can cause that muscle to tighten and squeeze the genitofemoral nerve as it passes through, creating referred pain in the testicle.1PubMed Central. Atypical manifestations of lumbar discogenic pain: a case of thigh and testicular pain associated with a high-intensity zone
One well-documented case involved a 60-year-old man with a three-year history of low back pain and two years of unexplained right-sided testicular pain. His MRI showed disc protrusions at L1/L2, L3/L4, and L4/L5, all causing indentations of the spinal sac. After conventional urological causes were ruled out, his doctors attributed the testicular pain to the disc disease. Both his back pain and testicular pain resolved completely after eight weeks of spinal manipulation.2PubMed Central.

Another case described a 23-year-old with chronic low back pain whose testicular pain had persisted for more than three months. Analgesic discography during surgery confirmed that the pain originated from a degenerated lumbar disc. After the disc was treated surgically, the low back pain improved and the testicular pain did not return.3PubMed Central. Testicular pain originating from lumbar disc degeneration: A case report These reports are consistent in one respect: when the spinal problem was addressed, the testicular pain went away.
Where L5-S1 Fits Into the Picture
L5-S1 is the most common site for disc herniation in the lumbar spine, so people with pain radiating from this level naturally wonder whether it could be responsible for testicular symptoms. The honest answer is that L5-S1 is a less likely culprit than upper lumbar levels when it comes to testicular pain specifically. The L5 nerve root supplies sensation mainly to the outer lower leg and the top of the foot. The S1 root covers the back of the calf and the outside of the foot. Neither of these roots has a direct sensory connection to the scrotum.
That does not mean L5-S1 problems never coexist with testicular pain. Disc disease rarely confines itself to a single level. A spine with a significant L5-S1 herniation may also have degeneration at L3-L4 or L4-L5 that goes unnoticed because the lower herniation produces louder symptoms like sciatica. In the case of the 60-year-old patient mentioned above, the disc protrusions spanned three levels. If someone presents with both sciatica-type symptoms from L5-S1 and testicular pain, a clinician looking only at the lowest level could miss the upper-lumbar contribution entirely.
There is also the indirect sympathetic pathway to consider. The sympathetic trunk connects to the lumbar spine across several levels and communicates with the nerves that serve the pelvic organs. Severe disc disease at L5-S1 could theoretically irritate the sympathetic chain or the sinuvertebral nerve in a way that causes pain referral to the groin region. This mechanism is harder to pin down clinically, and no published case report has isolated L5-S1 as the sole spinal source of testicular pain. But the interconnectedness of nerve pathways in the lower spine means a clean separation between “levels that can cause testicular pain” and “levels that cannot” does not hold up perfectly in practice.
How Often Spinal Problems Get Overlooked
Chronic testicular pain accounts for roughly 2.5 to 4.8 percent of urology clinic visits. Up to half of those cases have no identifiable cause after standard workup.4PubMed Central. Chronic Orchialgia Stemming From Lumbar Disc Herniation: A Case Report and Brief Review That is a striking number. It means that for every two men walking into a urology office with chronic testicular pain, roughly one walks out without a clear diagnosis. Lumbosacral problems may be a commonly overlooked contributor to those unexplained cases.
Part of the problem is that the typical diagnostic path for testicular pain runs through urology, not orthopedics or neurology. A urologist will check for infection, varicocele, epididymitis, torsion, and structural abnormalities of the testicle. If those tests come back negative, the pain often gets labeled as idiopathic, meaning “we don’t know.” Referring the patient for a lumbar MRI is not standard practice in many urology workflows, even though the spine is a recognized source of referred pain to the scrotum.5PubMed Central.

The reverse scenario also happens. Someone being treated for a lumbar disc herniation may mention testicular pain to their spine surgeon, who dismisses it as unrelated because L5-S1 pathology does not classically produce groin symptoms. Both specialists are operating within their own diagnostic frameworks, and the patient falls through the gap between them. Chronic orchialgia secondary to lumbar disc disease has only been described sporadically in the literature, which means many clinicians have never encountered it and do not think to look for it.4PubMed Central.

Getting the Diagnosis Right
If you have testicular pain alongside low back pain and no one has been able to explain the testicular symptoms, a lumbar MRI is worth discussing with your doctor. The key diagnostic clue is when standard urological workup turns up nothing: no infection, no varicocele, no mass, no trauma history. At that point, the question becomes where the pain signal is actually originating, and imaging the lumbar spine can reveal disc herniations, protrusions, or degenerative changes that could be generating referred pain.
In the published cases where this connection was established, the pattern was consistent. The patient had back pain alongside testicular pain, standard scrotal and urological evaluations were negative, and lumbar imaging showed disc pathology. In one case, the clinician confirmed the link during surgery by using analgesic discography, a technique where the disc suspected of causing pain is injected with anesthetic. When the disc was numbed, both the back pain and the testicular pain disappeared, confirming the disc as the source.3PubMed Central. Testicular pain originating from lumbar disc degeneration: A case report
Not every case will have that level of diagnostic precision. For most people, the practical indicator is whether treating the spinal problem relieves the testicular symptoms. If it does, the connection is established clinically even without an invasive test to prove it. If it doesn’t, other causes need continued investigation.
Treatment and Whether It Actually Resolves the Testicular Pain
The encouraging finding across published cases is that when the spinal problem is addressed, the testicular pain tends to resolve along with it. The treatments used have varied from conservative to surgical, and both ends of the spectrum have produced results.
On the conservative side, spinal manipulation, therapeutic ultrasound, and intermittent motorized traction have been used. In two reported cases of chronic testicular pain attributed to lumbar disc herniation, patients had previously tried anti-inflammatory medications, physical rehabilitation, and acupuncture with only temporary relief. They were then treated with targeted spinal interventions and experienced complete resolution of their chronic testicular pain after eight to nine weeks.6American Journal of Men’s Health. Is Lumbar Disk Herniation a Potential Risk Factor for Chronic Prostatitis/Chronic Pelvic Pain Syndrome? Insights From a Misdiagnosed Case The 60-year-old patient with multi-level disc disease also saw complete resolution of both back and testicular pain after eight weeks of chiropractic treatment.2PubMed Central. Taming of the Testicular Pain Complicating Lumbar Disc Herniation With Spinal Manipulation
Surgery has also been effective. In the case of the 23-year-old whose discogenic pain was confirmed intraoperatively, his testicular pain did not recur after the disc surgery.3PubMed Central. Testicular pain originating from lumbar disc degeneration: A case report The fact that both conservative and surgical approaches produced lasting relief in different patients suggests that any effective treatment of the underlying disc pathology can eliminate the referred pain, regardless of the specific method used.
These are all case reports, though, not randomized trials. The evidence is suggestive and consistent, but the total number of documented cases in the literature is small. No one has studied this connection in large groups, so it is difficult to say what percentage of patients with spinal-origin testicular pain will experience full resolution with treatment. What the case literature does show is that resolution is possible and has happened repeatedly when the right diagnosis was made.
Pudendal Nerve Pain and How It Differs
One condition worth distinguishing from spinal-origin testicular pain is pudendal nerve entrapment. The pudendal nerve originates from the S2-S4 sacral roots and supplies sensation to the perineum, including parts of the scrotum. When this nerve gets compressed or entrapped, it produces chronic neuropathic pain in the perineal area that typically worsens with sitting.7PubMed. Pudendal entrapment as an etiology of chronic perineal pain: Diagnosis and treatment
The distinguishing feature is position sensitivity. Pudendal nerve pain flares when you sit and tends to ease when you stand or lie down. Spinal-origin referred pain from disc herniation does not follow this pattern as closely; it often varies with movements that load the lumbar spine, like bending or lifting, and may worsen with activities that increase pressure on the discs. The pain character also differs. Pudendal neuralgia is typically described as burning, stabbing, or electric, concentrated in the perineum and inner thighs. Spinal-referred testicular pain is more often a deep ache that the patient localizes to the testicle itself.
Both conditions are frequently misdiagnosed. A man with pudendal nerve entrapment may go through the same urology workup as someone with disc-related testicular pain, get the same negative results, and receive the same “idiopathic” label. The treatment pathways diverge significantly, though: pudendal entrapment often requires nerve blocks or surgical decompression of the nerve at its entrapment site, while spinal-origin pain responds to treatment of the lumbar disc or nerve root.
When to Push for a Spinal Evaluation
If you have chronic testicular pain and a history of low back problems, stiffness, or sciatica, and urological tests have come up empty, a spinal evaluation is a reasonable next step. The connection is strongest when the testicular pain started around the same time as back symptoms, or when the two seem to flare and calm together. But even in cases where back pain is mild or intermittent, lumbar disc degeneration can be silently generating referred pain elsewhere.
Mention both symptoms to whatever specialist you are seeing, even if they seem unrelated. Urologists are increasingly aware of the spinal connection, but it remains underrecognized. Ask specifically about whether a lumbar MRI is warranted. If disc pathology is found, particularly at upper or mid-lumbar levels, and nothing else explains the testicular symptoms, treating the spine first is a reasonable strategy before considering more invasive urological procedures like spermatic cord denervation or epididymectomy, which carry their own risks and are sometimes performed on patients whose pain was never scrotal in origin to begin with.
The broader lesson from these case reports is that pain does not always originate where it is felt. The nervous system is a network, and a problem at one node can create symptoms at distant points. For testicular pain, the lumbar spine is one of those nodes, and it gets checked far less often than it should.
