Can Low Testosterone Cause Joint Pain? What Evidence Shows

By Noophoric Editorial Team Updated August 31, 2026

Short answer: Low testosterone may coexist with muscle weakness, lower bone density and some musculoskeletal conditions, but joint pain alone is not a recognized way to diagnose testosterone deficiency. Research has not established that low testosterone directly causes common joint pain or that testosterone therapy is a reliable treatment for arthritis.

Key takeaways

Joint pain has many more common causes than low testosterone.
Testosterone affects muscle and bone more clearly than it affects joint pain.
Associations between hypogonadism and inflammatory disease do not prove that one causes the other.
Testosterone therapy has not been established as an arthritis or joint-pain treatment.
Testing should be based on a complete symptom pattern and repeated morning hormone measurements.

Why people connect testosterone and joint pain

Testosterone contributes to muscle mass and bone metabolism. Men with hypogonadism may have reduced lean mass, lower physical capacity or osteoporosis. Those changes can affect mobility and how the body tolerates physical load, but they are not the same as inflammation or damage inside a joint.

Some inflammatory diseases are also associated with lower testosterone. Chronic inflammation, illness, glucocorticoid treatment and reduced activity can all influence hormone levels. This makes cause and effect difficult to separate.

What the research actually shows

A 2023 meta-analysis of randomized placebo-controlled trials found that testosterone therapy increased hip bone density and total lean mass after six months. Effects on grip strength were unclear, and benefits were not consistently evident at twelve months.^[2] Joint pain was not established as a primary treatment outcome.

Reviews of sex hormones and musculoskeletal pain describe biologically plausible relationships, but they also emphasize that hormone replacement as a pain treatment remains far less established than the associations themselves.^[3]

A small prospective pilot study reported less joint pain when hypogonadal men already receiving testosterone were given nandrolone, a different anabolic steroid.^[4] That study was not a blinded trial of testosterone for common joint pain and cannot support the claim that TRT treats arthritis.

Common causes of joint pain

Depending on the location and pattern, possibilities include:

Osteoarthritis
Tendon or ligament injury
Overuse or a change in training load
Gout
Rheumatoid arthritis or another inflammatory condition
Infection
Medication effects
Referred pain from the spine or surrounding muscles

The location, swelling, warmth, morning stiffness, recent injury and duration are usually more informative than testosterone status.

When could low testosterone be relevant?

A clinician might consider hormone testing when joint or muscle complaints occur with more specific features such as reduced libido, fewer spontaneous erections, infertility, loss of body hair, unexplained anemia, reduced muscle mass, low-trauma fracture or low bone density.

The Endocrine Society recommends diagnosing hypogonadism only in men with compatible signs or symptoms and unequivocally and consistently low testosterone concentrations. A low result should be repeated in the morning while fasting.^[1]

Testing testosterone solely because a knee or shoulder hurts is unlikely to identify the cause.

Does testosterone therapy help joint pain?

Testosterone therapy can be appropriate for confirmed hypogonadism after evaluation of the cause, risks and fertility goals. It may improve lean mass or certain symptoms of deficiency, but it is not an approved treatment for osteoarthritis, rheumatoid arthritis or nonspecific joint pain.

Even when pain improves after treatment, the change may reflect improved energy, muscle conditioning, mood or activity rather than a direct repair of cartilage. A response in one person does not establish the original cause.

What to do about persistent joint pain

Identify the pattern. Note the location, onset, swelling, stiffness and activities that worsen or relieve it.
Adjust obvious overload. Reduce a recent training spike without becoming completely inactive.
Use progressive strength and mobility work. A physical therapist can tailor this to the joint and diagnosis.
Address sleep and body weight. Both can affect pain sensitivity and joint loading.
Get evaluated when pain persists. The right treatment depends on the cause.

If excess weight and low testosterone are both concerns, see our evidence review on testosterone and body fat.

When to seek prompt medical care

Seek urgent assessment for a hot, red or rapidly swollen joint; fever with joint pain; inability to bear weight after an injury; a visibly deformed joint; or severe pain that begins suddenly. These features can indicate infection, fracture, gout or another condition that should not be attributed to hormones.

Frequently asked questions

Can low testosterone cause aching joints?

A direct causal link has not been established. Low testosterone can affect muscle and bone, but common joint pain has many other causes.

Is joint pain a symptom of low testosterone?

It is not specific enough to diagnose hypogonadism. More characteristic sexual, reproductive, blood or body-composition signs make testing more relevant.

Does TRT repair cartilage?

No clinical evidence establishes TRT as a cartilage-regrowth treatment.

Could low testosterone increase fracture risk?

Long-standing hypogonadism can contribute to low bone density. Bone pain or fractures are different from ordinary joint pain and deserve appropriate evaluation.

The bottom line

Testosterone matters for muscle and bone health, but the evidence does not support treating joint pain as proof of low testosterone. Persistent or inflammatory joint symptoms should be evaluated for their actual cause. Testosterone testing and therapy should follow established hypogonadism guidelines, not be used as a general arthritis solution.
