Can You Hurt Your Testicles From Lifting Something Heavy?

Heavy lifting can absolutely cause testicular pain, though it rarely damages the testicles themselves. The discomfort typically comes from structures surrounding the testicles or from problems elsewhere in the body that refer pain downward. Inguinal hernias, muscle spasms, pelvic floor strain, pinched nerves, and swollen veins are all plausible culprits, and heavy lifting can trigger or worsen every one of them. Understanding which mechanism is at play matters, because the causes range from benign and self-limiting to conditions that need medical attention.

Inguinal Hernias and the Weakness Built Into Your Anatomy

The most well-known way lifting can affect the groin and testicles is by provoking an inguinal hernia. The inguinal canal is a passage in the lower abdominal wall through which the spermatic cord travels down to the scrotum. It exists because the testicles descend through it during fetal development, and the canal never fully closes afterward. That leftover opening creates an inherent structural weak point. In upright humans, the weight of the abdominal organs presses down toward this weak spot constantly, and the problem gets dramatically worse when you increase intra-abdominal pressure by straining under a heavy load.¹

When tissue pushes through that weak point, it can press against the spermatic cord or sit right next to the testicle in the scrotum, producing a dull ache, a burning sensation, or a feeling of heaviness. The pain often worsens with continued lifting, coughing, or standing for long periods and eases when you lie down. A visible or palpable bulge near the groin is the classic sign, but not every hernia produces one, especially in the early stages. Small hernias can cause testicular pain without any obvious lump.

This is the scenario most people picture when they worry about “hurting themselves” while lifting. It is also one of the most common surgical conditions in men globally. But hernias are far from the only mechanism connecting heavy loads to scrotal pain.

When the Cremaster Muscle Overreacts

Wrapped around each spermatic cord is a thin muscle called the cremaster. Its everyday job is to raise and lower the testicles in response to temperature and touch, keeping them in the narrow thermal range that sperm production requires. During heavy exertion, the cremaster contracts as part of the body’s broader abdominal bracing response. In most people, this is a barely noticeable tightening. In some, the muscle contracts forcefully enough to pull the testicle high into the inguinal canal, producing sharp pain, a sensation of the testicle “disappearing,” and lingering soreness afterward.

Men who experience this chronically tend to have significantly thicker cremaster muscles than average. One study comparing men with chronic testicular retraction to controls found that the cremaster in the retraction group was nearly four times thicker, averaging about 3.9 mm compared with 1.0 mm in controls.² That structural difference means the muscle can generate more force when it contracts, making retraction episodes more frequent and more uncomfortable.

Intense physical activity can also set off a persistent spasm rather than just a momentary contraction. A published case described a 37-year-old man who developed bilateral testicular pain and chronic retraction after a sports injury that tore his hamstring and partially tore his lower abdominal muscles. His cremaster muscles were found to be in sustained tonic spasm, pulling both testicles up and rapidly retracting them whenever they were manually brought back down.³ While this case involved acute trauma rather than a single lift, it illustrates how abdominal and pelvic muscle injuries can cascade into cremaster dysfunction. Heavy lifting that strains the lower abdominal wall can trigger similar, usually milder, episodes.

Pelvic Floor Strain and Chronic Scrotal Pain

Your pelvic floor muscles form a hammock of tissue at the base of the pelvis. They support the bladder and bowel, help control continence, and play a role in sexual function. They also contract reflexively when you brace to lift something heavy, and in people who lift often or who carry chronic tension in the area, the pelvic floor can become hypertonic, meaning it stays partly contracted even at rest.

That chronic tightness is surprisingly common in men with unexplained testicular pain. In one study, nearly nine out of ten men with chronic scrotal pain had elevated resting tone in their pelvic floor muscles, measuring about 6.7 microvolts on electromyography compared with a normal threshold below 3.⁴ The researchers concluded that chronic testicular pain can be a direct symptom of pelvic floor overactivity, particularly in younger men. A clinical review of the biomechanical links between pelvic floor dysfunction and testicular pain echoed these findings and added that high levels of physical activity might be a key contributor. In one illustrative case, a competitive long-distance runner developed testicular pain rooted in pelvic floor dysfunction, and the authors suggested his level of exertion was the likely trigger.⁵

This kind of pain tends to be dull and diffuse rather than sharp, and it often worsens during the day, especially with prolonged sitting or standing after exercise. It can linger for weeks or months because the underlying muscle imbalance does not resolve on its own. Many men who end up in this cycle had no idea their pelvic floor was involved, since the pain feels like it is originating in the testicle itself. Pelvic floor physical therapy, which focuses on learning to relax the overactive muscles rather than strengthening them, is one of the primary treatment approaches.

Nerve Entrapment and Referred Pain

The testicles share nerve pathways with the lower abdomen, hip, and lumbar spine. That overlap means pain originating nowhere near the scrotum can feel like it is coming directly from the testicle. Two scenarios are common enough to be worth knowing about if you lift heavy things regularly.

The first involves the ilioinguinal and genitofemoral nerves, which run through or near the inguinal canal. Repetitive heavy lifting can irritate or compress these nerves along their path through the abdominal wall. The result is a burning or shooting pain that radiates into the groin and scrotum. Because the pain is testicular, men often undergo extensive urological workups that come back normal. A case study described a patient with chronic testicular pain who had been through standard evaluations without answers until clinicians considered nerve entrapment along the inguinal canal and treated it with a conservative physical therapy program targeting the nerve’s path. The pain resolved.⁶

The second scenario involves the lumbar spine. Disc degeneration or herniation at certain spinal levels can refer pain to the testicle because the nerve roots exiting the lower spine supply sensation to the scrotum. A case report described a 23-year-old man with chronic low back pain who also had persistent testicular pain for over three months. When his disc problem was treated with an intradiscal injection, both the back pain and the testicular pain resolved, and the testicular pain did not return.⁷ Heavy lifting, of course, is one of the leading causes of lumbar disc injury, which makes this an indirect but real route from a heavy deadlift to scrotal pain.

If you have testicular pain that comes with lower back stiffness, hip tightness, or worsens with certain postures, referred pain from the spine or nerve entrapment in the abdominal wall should be on the list of possibilities. These diagnoses are often missed early because clinicians understandably focus on the testicle itself first.

Varicocele and Venous Pressure

A varicocele is an enlargement of the veins within the scrotum, similar to varicose veins in the legs. It happens when the valves in the veins draining the testicle do not close properly, allowing blood to pool. The left side is more commonly affected because of how the left testicular vein connects to the renal vein at a steeper angle.

Heavy lifting and straining increase abdominal pressure, which in turn increases pressure in those testicular veins. The Valsalva maneuver, the grunt-and-bear-down effort that happens naturally during a heavy lift, temporarily dilates these veins. In men with healthy venous valves, this is harmless. In men with early valve incompetence, repeated spikes in venous pressure can worsen the pooling over time. Ultrasound studies of varicoceles routinely use the Valsalva maneuver to make the dilated veins more visible, because straining increases venous diameter measurably.⁸

Varicoceles themselves cause a characteristic dull, achy heaviness in the scrotum that worsens with standing and physical exertion and improves when lying down. They are quite common, affecting roughly 15 percent of men overall and a higher proportion of men evaluated for infertility. The concern is not only pain but also the effect on sperm quality, since the pooled blood raises scrotal temperature. Research on athletes with varicoceles found that after six months of stopping all sports activity, both sperm concentration and motility improved significantly.⁹ That does not mean every man with a varicocele needs to stop exercising, but it does suggest that chronic heavy exertion can aggravate the condition’s effects on fertility.

How to Tell What Is Going On

With so many possible causes, the character and timing of the pain gives useful clues before you ever see a doctor.

Pain during the lift itself: A sharp, sudden pain in the groin during a heavy lift, especially with a visible or palpable bulge, points strongly toward an inguinal hernia. Sudden severe testicular pain that does not involve a bulge warrants emergency evaluation to rule out testicular torsion, where the testicle twists on its cord and loses blood supply.
Pain shortly after lifting: A cramping sensation with the testicle riding higher than usual suggests cremaster spasm. This typically resolves within minutes to hours. A warm bath or gentle manual repositioning can help.
Dull ache that builds over hours: A diffuse heaviness that worsens through the day, especially with standing, fits the pattern of varicocele or pelvic floor tension. If it improves when you lie down, venous pooling is more likely. If it persists regardless of position, pelvic floor hypertonicity is worth considering.
Burning or shooting pain into the groin: Pain with a burning, electric quality that follows a path from the lower abdomen into the scrotum suggests nerve irritation, either from entrapment in the abdominal wall or from a lumbar disc issue. Concurrent back pain raises the odds of a spinal origin.

Testicular torsion deserves special emphasis because it is one of the few true emergencies. It typically produces sudden, excruciating pain, often with nausea and swelling, and it requires surgical correction within hours to save the testicle. While torsion is more common in adolescents and is usually not triggered by lifting, any sudden severe testicular pain should be evaluated urgently regardless of context.

Practical Steps for People Who Lift Regularly

Most testicular pain from lifting is preventable or manageable without giving up training. Proper bracing technique is the starting point. Learning to brace your core by expanding your abdomen against a tightened midsection, rather than simply holding your breath and bearing down as hard as possible, reduces the spike in intra-abdominal pressure that stresses the inguinal canal and testicular veins. The distinction matters: effective bracing stabilizes the spine without generating unnecessary pressure in the lower pelvis.

Breathing patterns also play a role. Exhaling during the hardest part of a lift, or at least avoiding prolonged breath-holding, moderates pressure buildup. Competitive powerlifters and strongmen accept higher pressures as a tradeoff for maximum force production, and they have correspondingly higher rates of inguinal hernia than the general population. Recreational lifters do not need to accept that tradeoff.

If you are already dealing with a dull ache after workouts, a few adjustments are worth trying before assuming something is seriously wrong. Reducing volume on exercises that increase abdominal pressure, particularly heavy squats, deadlifts, and overhead presses, for a couple of weeks often settles cremaster irritability and pelvic floor tension. Supportive underwear during training reduces the mechanical bouncing that can aggravate a varicocele or an already irritated cremaster. Stretching the hip flexors and lower back after lifting can reduce tension on the nerves that refer pain to the scrotum.

For recurring or persistent pain, pelvic floor physical therapy has growing evidence behind it. This is not the Kegel-focused strengthening that most people associate with pelvic floor work. For men with hypertonic pelvic floors, the therapy involves learning to consciously relax the muscles, often through breathing exercises, manual therapy, and biofeedback. Given that nearly nine in ten men with chronic scrotal pain show elevated pelvic floor tone, this is an underused approach that addresses a common root cause.⁴

Why So Many Workups Come Back “Normal”

One of the more frustrating experiences men report is having testicular pain evaluated and being told that ultrasound and bloodwork look fine. This happens frequently because standard urological evaluation focuses on pathology within the testicle, looking for masses, infections, torsion, or large varicoceles. When those are absent, the workup is often declared negative.

But as the evidence above shows, a large proportion of chronic testicular pain originates outside the testicle entirely. Pelvic floor dysfunction, nerve entrapment in the abdominal wall, and lumbar spine problems all produce genuine testicular pain through referred pathways, and none of them show up on a scrotal ultrasound. Clinicians are increasingly recognizing this gap. The case study on ilioinguinal nerve entrapment described how a patient went through extensive standard evaluation before the musculoskeletal cause was identified.⁶ If your ultrasound is clean but the pain persists, asking about pelvic floor assessment or nerve-related causes is a reasonable next step.

Varicoceles, Fertility, and the Long Game

For men who plan to have children, the varicocele question deserves extra attention. Most varicoceles are painless and never cause problems. But when a varicocele is present and a man is doing heavy physical training regularly, the combination of elevated scrotal temperature from venous pooling and repeated pressure spikes from lifting can affect sperm parameters over time. The study on athletes who stopped sports activity for six months showed statistically significant improvements in both sperm concentration and motility after the rest period.⁹

That finding does not mean lifting causes infertility. It means that in men who already have a varicocele, heavy training may worsen its effect on sperm quality, and reducing the physical load can reverse some of that impact. If you have a known varicocele and are actively trying to conceive, it is worth discussing training modifications with a urologist. For men without varicoceles, there is no evidence that heavy lifting impairs fertility through any of the other pain mechanisms discussed here. The testicle itself is well protected inside the scrotum, and pain from surrounding structures does not translate to testicular damage.
