High Testosterone in Men: Causes, Signs and When It Signals a Problem

A reader wrote to us about his gym buddy, who had started saying “my T is through the roof” the way other people mention their resting heart rate. He had bought a home test kit, got a number near the top of the range, and treated it as a trophy. The reader’s question was simple: should he be impressed or worried?

He is not alone in asking. As of 2026, searches for high testosterone in men have climbed alongside a wave of social-media “testosterone optimization” content, direct-to-consumer hormone testing, and headlines from the large TRAVERSE cardiovascular safety trial that reshaped how clinicians talk about testosterone therapy. The result is a lot of men looking at a lab printout with no idea what the number means.

This explainer walks through what counts as high, what actually produces it, which risks are supported by solid evidence and which are not, and when a result deserves a doctor’s attention rather than a shrug or a celebration.

What counts as high testosterone in men?

Testosterone is the main male sex hormone, a chemical messenger made mostly in the testicles that drives muscle mass, bone density, sperm production, body hair and libido. Laboratories report it in nanograms per deciliter (ng/dL), and the adult male reference range sits roughly between 300 and 1,000 ng/dL, although MedlinePlus notes that exact cutoffs vary from one lab to another and by the method used.

A “high” result, then, is any value above the upper limit printed on your own report, not a number borrowed from a forum. Two details matter before anyone attaches meaning to it. First, testosterone follows a daily rhythm, peaking in the early morning and dipping by late afternoon, which is why clinicians ask for blood drawn between roughly 7 and 10 a.m. A sample taken at 8 a.m. can read 20 to 30 percent higher than one taken at 4 p.m. in the same man.

Second, there are two kinds of measurement. Total testosterone counts every molecule in the blood, including the large share bound tightly to sex hormone-binding globulin (SHBG), a liver-made protein that acts like a carrier and keeps hormone inactive. Free testosterone is the small unbound fraction, usually 1 to 3 percent, that can enter cells and act. A man with high SHBG can have a lofty total but ordinary free testosterone, and the reverse is also true.

For most healthy men, a single reading slightly above range is a statistical event, not a diagnosis. Reference ranges are built to include about 95 percent of healthy people, which means roughly one in forty healthy men will fall above the top line on any given morning. Persistence is what turns a number into a finding.

What happens when testosterone is high in males?

The body treats testosterone like a thermostat setting. The hypothalamus and pituitary gland in the brain release signals, chiefly luteinizing hormone (LH), that tell the testicles how much to make; when blood levels rise, those signals fall. Endocrinologists call this loop the hypothalamic-pituitary-gonadal axis. It is the reason that a man whose testosterone is pushed high from outside, by a gel, injection or anabolic steroid, usually ends up with shrinking testicles and a sharp drop in sperm count: the brain has switched off the factory.

Excess testosterone also does not stay testosterone. An enzyme called aromatase, abundant in fat tissue, converts part of it into estradiol, the main estrogen. That conversion is why men with very high androgen levels can develop enlarged male breast tissue (gynecomastia), a tender swelling under the nipple, and why water retention and mood swings sometimes accompany the muscle gains people expect.

Bone marrow is another target. Testosterone stimulates red blood cell production, and at supraphysiologic levels, meaning higher than the body would ever make on its own, it can raise hematocrit, the percentage of blood volume made up of red cells. Thickened blood is one of the best-documented consequences of testosterone therapy, and Mayo Clinic lists it among the effects doctors monitor most closely.

Skin oil glands respond with acne, often across the back and shoulders. Scalp hair follicles in genetically susceptible men respond with faster male-pattern thinning. Blood pressure can tick upward, and sleep apnea, a condition where breathing repeatedly stops during sleep, may worsen. None of these effects is guaranteed in any individual, and the degree depends on how high, for how long, and whether the hormone came from inside the body or a bottle.

Signs of high testosterone in men: what to actually look for

Viral lists promise fifteen or twenty “signs of high testosterone in men,” usually including a square jaw, a deep voice and confidence. Most of those are features of being an adult male, not markers of an abnormal level. Honest clinical experience narrows the list considerably, and the signs cluster into a few groups.

Skin and hair changes come first: new or worsening acne in adulthood, oily skin, and faster hair loss at the temples and crown. Fluid and tissue changes come next: puffiness, unexpected weight gain that is not fat, and enlarged male breast tissue (gynecomastia). Reproductive signs include smaller, softer testicles and difficulty conceiving, which is counterintuitive to people who assume more hormone means more fertility.

Mood and sleep deserve their own mention. Irritability, short temper, restlessness, insomnia and, in some men, unusual euphoria or risk-taking are reported with supraphysiologic levels, particularly in people using anabolic steroids. The National Institute on Drug Abuse (NIDA) describes extreme mood swings and aggression among the recognized effects of steroid misuse.

Finally, there are the quiet signs that show up only on a blood test or a cuff: high hematocrit, elevated blood pressure, and shifts in cholesterol with lower HDL (the protective kind).

How can a man tell if he has high testosterone? In practice, he usually cannot by looking in the mirror. Natural levels within the normal range produce no reliable outward signature, and men at the top of the range are not visibly different from men in the middle. A blood test, drawn in the morning and repeated if abnormal, is the only way to know. Symptoms are a reason to test, not a substitute for testing.

What causes high testosterone in men?

When a clinician sees a genuinely high result in an adult man, the first question is not about his body at all. It is: what is he taking? By a wide margin, the most common cause of high testosterone in men is testosterone that came from outside, whether a prescribed therapy, an anabolic steroid, or a supplement contaminated with undeclared hormones. NIDA notes that anabolic steroids are synthetic variations of testosterone, and all of them push the body’s androgen signal above its natural ceiling.

Natural causes exist, but they are rare and tend to announce themselves. A testicular tumor arising from Leydig cells, the cells that normally make testosterone, can secrete it in excess; most of these tumors are benign, but they need evaluation. Adrenal tumors can do the same, since the adrenal glands, two small organs atop the kidneys, also produce androgens.

Congenital adrenal hyperplasia (CAH) is an inherited condition in which an enzyme deficiency diverts adrenal hormone production toward androgens. Severe forms are picked up in newborn screening; milder, late-onset forms can appear in adolescence or adulthood with acne, early puberty or fertility problems. In boys, precocious puberty, meaning puberty beginning before age nine, is driven by early androgen production and is a classic pediatric cause of high levels.

A few other patterns raise total testosterone without truly raising active hormone. Hyperthyroidism and some liver conditions increase SHBG, lifting the total while free testosterone stays normal. Certain medicines can shift the measurement too. Vigorous exercise shortly before a blood draw, or a very early draw time, produces a modestly higher number that means nothing clinically.

This is why repeat testing matters so much. A second morning sample, ideally with free testosterone and SHBG measured alongside the total, sorts a lab fluke from a real pattern before anyone starts imaging or referrals.

What changed recently

Three developments explain why this question has resurfaced so loudly. The first is scientific. In 2023, results from the TRAVERSE trial, a randomized, placebo-controlled study that followed about 5,200 middle-aged and older men with low testosterone and existing heart disease or high cardiovascular risk for several years, were published. Testosterone therapy did not increase the combined rate of heart attack, stroke and cardiovascular death compared with placebo. The same trial, however, recorded higher rates of atrial fibrillation, pulmonary embolism and acute kidney injury in the treated group. That mixed picture ended a decade of uncertainty while opening new monitoring questions.

The second is regulatory. In early 2025, the U.S. Food and Drug Administration announced class-wide labeling changes for prescription testosterone products, removing the earlier boxed warning about increased cardiovascular risk and adding a new warning about increases in blood pressure. Clinicians read this as an invitation to measure blood pressure more carefully, not as a green light to aim high.

The third is cultural, and it is the engine behind most of the searching. Telehealth hormone services, home finger-prick testing and a steady stream of “optimize your T” content have normalized the idea that every man should know his number and push it upward. Harvard Health’s long-running coverage of testosterone has repeatedly cautioned that benefits in men with normal levels are unproven, and Mayo Clinic’s patient guidance continues to describe testosterone therapy as treatment for medically confirmed hypogonadism, the clinical term for inadequate hormone production, rather than a general tonic.

Put together, the recent evidence makes one thing clearer than before: the risks of testosterone relate less to a man’s natural level than to pushing levels above where his body would set them.

Testosterone test: how to read a high result

A testosterone test report usually carries three lines: total testosterone, free testosterone, and sometimes SHBG. MedlinePlus describes the total test as the standard starting point and the free test as a second step when the total is borderline or when SHBG may be abnormal.

Reading the result starts with the draw time. If the sample was taken in the afternoon, after a night shift, or within an hour of heavy exercise, the number is less trustworthy in either direction. The next check is the method. Immunoassays, the automated tests most labs run, are convenient but less accurate at the extremes; liquid chromatography with mass spectrometry, often abbreviated LC-MS/MS, is the reference method and is preferred when a result is surprising.

Then comes context. A total near the top of the range in a lean, physically active man in his twenties is expected; the same value in a man of seventy who has never taken hormones is unusual and worth a second look, because testosterone normally declines about 1 percent per year after the thirties.

Clinicians also look at what else is on the panel. A high testosterone with a suppressed LH suggests the hormone is coming from somewhere other than the testicles responding to the brain, such as a product being used or a tumor making hormone independently. A high testosterone with a high LH is a different story and points toward the brain-level signal being overactive. Hematocrit, estradiol, prostate-specific antigen (PSA, a protein measured in prostate monitoring) and liver tests round out the picture.

Home kits can be useful screens, but a result that is going to change what you do should be confirmed by a laboratory draw ordered and interpreted by a clinician who can see the whole panel and your history.

Is high testosterone bad for men? The risks, ranked by evidence

The answer depends almost entirely on where the hormone comes from. For men with naturally high-normal levels, the evidence of harm is thin and largely observational. For men whose levels are pushed above the natural ceiling by anabolic steroids or unsupervised products, the evidence of harm is consistent and comes from many directions.

Best supported are the blood and cardiovascular effects of supraphysiologic use: raised hematocrit, which thickens blood and increases clot risk; elevated blood pressure; a fall in HDL cholesterol; and, in long-term steroid users, changes in heart muscle structure. NIDA and the NHS both list heart attack, stroke and blood clots among the serious harms of steroid misuse. Reproductive harm is equally well documented: testicular shrinkage and impaired sperm production occur in the large majority of men on sustained high doses, and recovery after stopping can take months to more than a year, sometimes incompletely.

Moderately supported are skin, hair and breast tissue changes, mood disturbance and worsened sleep apnea. These are reported repeatedly in clinical series and trials of testosterone therapy, though severity varies widely.

Weakly supported, resting on observational studies rather than trials, are links between higher testosterone and immune function. Laboratory work shows testosterone dampens some immune responses, and a few observational studies have associated higher levels with weaker antibody responses to vaccination. These are intriguing associations, not proven effects on infection risk in everyday life.

Where evidence is reassuring: large observational cohorts have not consistently shown that higher natural testosterone raises prostate cancer risk, and the TRAVERSE trial did not find more prostate cancer in treated men over its follow-up. Prostate screening decisions still follow age- and risk-based guidance, which belongs in a conversation with a clinician rather than a checklist.

Naturally high versus artificially high: a side-by-side table

Much of the confusion online comes from blending two very different situations. One is a man whose own body sets his testosterone at the upper end of normal. The other is a man whose level has been driven above the natural range from outside. The table summarizes how they differ.

Feature	Naturally high-normal level	Supraphysiologic level from products or steroids
Typical total testosterone	Upper part of the lab range	Often several times the upper limit
LH signal from the brain	Normal	Suppressed, sometimes undetectable
Testicle size and sperm count	Normal	Reduced, often markedly
Hematocrit	Usually normal	Frequently elevated
Blood pressure and HDL	No consistent change	Pressure up, HDL down
Acne, hair loss, breast tissue	Uncommon as new symptoms	Common
Mood effects	Not reliably different	Irritability, aggression, mood swings reported
Strength of harm evidence	Weak, observational	Strong, consistent across many studies
Usual medical response	Confirm, then reassure	Evaluate, monitor, address the source

The table also explains why the question “is high testosterone bad for men” has no single answer. A level that is high because the body made it is, for most men, a trait rather than a condition. A level that is high because of an external source carries predictable consequences, and the higher and longer the exposure, the more of them tend to appear.

One caution about the first column: a persistently high natural level is still uncommon enough that clinicians confirm it and consider the rare tumor or adrenal causes described earlier before filing it as a personal quirk.

Anabolic steroids, testosterone products and the numbers they produce

Anabolic-androgenic steroids are laboratory-made compounds built on the testosterone molecule and designed to amplify its muscle-building (anabolic) effects. Testosterone itself, in prescription forms such as gels, patches, injections and implanted pellets, is a licensed medicine for men with diagnosed hypogonadism. The same molecule, taken without a diagnosis or in amounts beyond what a clinician would prescribe, becomes a performance drug with a well-mapped side-effect profile.

The scale of use is larger than many expect. NIDA reports that steroid misuse is most common among men in their twenties and thirties, often driven by appearance goals rather than competitive sport, and that users frequently combine several compounds in cycles. The NHS adds that many people obtain these products illegally, with no assurance of what the vial actually contains.

Men who misuse steroids can show total testosterone readings far above any natural value, together with a near-absent LH. Over months, the pattern described earlier unfolds: testicular shrinkage, infertility, acne, enlarged male breast tissue, thickened blood, raised blood pressure and, with oral compounds in particular, liver strain. Psychological effects range from irritability to paranoia and depression, and the low mood after stopping can be severe enough to keep people using.

A separate category deserves a plain statement. Unapproved “research” compounds, including selective androgen receptor modulators (SARMs) and various peptides marketed online, are not approved for human use in the United States or the United Kingdom, are not legally for sale as supplements, and have no established safety data in people. Some dietary supplements marketed for “testosterone support” have been found to contain undeclared steroids. None of these products is appropriate for self-use.

For any man already using testosterone or steroids, the safest path is medical, not solitary. Abruptly stopping can bring its own problems, and a clinician can guide evaluation and next steps.

What the evidence actually says

Medical evidence comes in grades, and it helps to label each claim about high testosterone with the kind of study behind it.

Randomized controlled trials, the strongest design, exist mainly for prescribed testosterone in men with low levels. From them we know that treatment raises hematocrit in a dose-related way, modestly increases blood pressure, and did not increase major cardiovascular events in the roughly 5,200-man TRAVERSE trial, though it did raise rates of atrial fibrillation, pulmonary embolism and acute kidney injury. Trials of testosterone in men with normal levels are few, small and short, and they have not shown meaningful benefits for mood, cognition or sexual function beyond what the body already provides. Harvard Health summarizes this as: benefits in men with normal levels are unproven.

Observational data, the middle tier, dominate the discussion of natural high-normal levels. Large cohort studies have linked higher testosterone to lower body fat and higher bone density, which is unsurprising since the hormone contributes to both. Other cohorts have associated higher levels with slightly higher risk of certain blood clots or with weaker immune markers. Observational studies cannot separate cause from correlation; men with higher testosterone also tend to be younger, leaner and healthier in ways that confound the picture.

Expert opinion, the weakest grade, fills the remaining gaps. The idea that prostate tissue stops responding to additional testosterone beyond a modest threshold, sometimes called the saturation model, is biologically plausible and widely cited but rests on mechanistic reasoning more than trial proof.

Evidence about steroid misuse sits in an unusual position: randomized trials of harmful doses would be unethical, so it comes from case series, cohort studies of users and physiological studies. Across all of them the findings are strikingly consistent, which is why clinicians treat the harms as established even without a placebo-controlled trial.

Is it better to have high or low testosterone?

The honest answer is neither. The body spends considerable effort keeping testosterone inside a range, and both tails of the distribution carry costs. Low testosterone, when confirmed and symptomatic, is associated with fatigue, reduced libido, erectile difficulty, loss of muscle and bone, anemia and low mood. Cleveland Clinic describes these as the classic features that prompt testing. High testosterone from external sources carries the thickened blood, reproductive shutdown and cardiovascular strain already described.

Within the normal range, there is little evidence that the top is better than the middle. Men at 800 ng/dL are not measurably stronger, sharper or happier than men at 500 ng/dL once age, body composition and health are accounted for. Muscle growth tracks training stimulus, protein intake and sleep far more closely than it tracks a natural hormone level inside the normal band. The hormone sets a permissive background; it does not do the work.

This matters because much of the current online conversation frames testosterone as a score to maximize. A more useful frame is sufficiency. Is the level enough to support normal function, and is it stable? If yes, there is nothing to optimize, and interventions aimed at pushing a normal level higher trade real, measurable risks for benefits that trials have not demonstrated.

There is one group for whom the question is genuinely clinical: men with confirmed hypogonadism, diagnosed by repeated low morning values and consistent symptoms. For them, testosterone therapy is a recognized treatment, and the goal clinicians aim for is a level in the mid-normal range, not the ceiling. Whether any individual qualifies, and what target is appropriate, is a decision that belongs to the treating clinician after a proper evaluation.

How do you fix high testosterone in men?

“Fix” is the wrong verb for most cases, because the right response depends on the cause, and in the most common scenario the fix is to address the source rather than the number.

When the elevation comes from a prescribed testosterone product, the clinician who prescribed it manages the response. That may involve re-checking the level at a different point in the treatment cycle, adjusting the regimen, or watching hematocrit and blood pressure more closely. Mayo Clinic notes that regular blood monitoring is part of responsible therapy. Men should never adjust or stop a prescribed hormone on their own; sudden changes can cause symptoms of their own and complicate interpretation.

When the elevation comes from anabolic steroids or unregulated products, the medical goal is a supervised path away from them, with attention to mood, sleep, blood counts and fertility. Recovery of the body’s own production can be slow, and clinicians sometimes involve an endocrinologist, a specialist in hormone disorders, especially when fertility is a concern.

When no external source exists and a repeat morning test confirms a high level, evaluation moves to finding the origin. Imaging of the testicles or adrenal glands may be ordered, and additional hormone tests can point toward congenital adrenal hyperplasia or another adrenal condition. Tumors producing hormone are generally treated surgically; adrenal enzyme conditions are managed medically by an endocrinologist. These are specialist decisions.

What about lifestyle? There is no reliable diet or exercise change that lowers a naturally high testosterone, and none is needed, because a natural level within or just above range is not a disease. Supplements and herbal products marketed to “balance hormones” have no trial evidence for this purpose. The useful lifestyle steps are the general ones: controlling blood pressure, not smoking, managing weight, and sleeping well, which protect the heart regardless of the hormone number.

Common myths about high testosterone in men

Viral content has produced a set of durable misconceptions. Here are the ones clinicians hear most, with what the evidence shows.

Myth: You can tell a man’s testosterone from his jawline, voice or body hair. These traits are set during puberty and shaped by genetics and sensitivity of hormone receptors. Adult men with very different testosterone levels look alike; only a blood test tells the difference.

Myth: Higher testosterone means more muscle, automatically. Within the normal range, muscle gain follows training and nutrition. Supraphysiologic levels from steroids do add muscle, which is exactly why they are banned in sport, but they bring the harms described throughout this article.

Myth: High testosterone makes men aggressive. In men with natural levels, studies linking testosterone to aggression are weak and inconsistent. Aggression and mood swings are well documented with steroid misuse, which is a different situation.

Myth: Cold showers, specific foods or “natural boosters” raise testosterone meaningfully. Small, short studies show trivial or transient changes at best. Sleep deprivation and significant weight gain lower testosterone; correcting those restores normal levels, which is not the same as boosting beyond normal.

Myth: More testosterone is always better for sex drive. Libido is supported by adequate testosterone, and men with low levels often improve with treatment. Pushing a normal level higher has not been shown to add anything in trials, and the reproductive shutdown from external hormone can impair sexual function.

Myth: High testosterone causes prostate cancer. Large observational studies have not shown that higher natural testosterone raises risk, and recent trial data did not show more prostate cancer with therapy over several years of follow-up. Prostate screening is guided by age and personal risk, discussed with a clinician.

Myth: A home test result is a diagnosis. It is a prompt for a proper morning laboratory draw, interpreted in context.

When to see a doctor

A single testosterone result at the upper edge of normal, with no symptoms and no products involved, usually warrants a repeat morning test rather than alarm. Beyond that, some situations call for a prompt appointment and some for urgent care.

Make an appointment if you have a confirmed high result on two morning tests; new acne, enlarged or tender breast tissue, or noticeable testicular shrinkage; difficulty conceiving; persistent irritability, insomnia or mood changes; or if a boy younger than nine shows signs of puberty such as genital growth, pubic hair, deepening voice or a sudden growth spurt. Make an appointment, too, if you are using testosterone or anabolic steroids from any non-prescribed source and want help evaluating your health or planning a supervised stop.

Seek urgent care for red-flag signs that can accompany thickened blood or cardiovascular strain: chest pain or pressure; sudden shortness of breath; pain, swelling or warmth in one calf; sudden weakness, facial drooping or trouble speaking; a severe headache unlike any you have had; blood pressure readings well above your usual with symptoms; or yellowing of the skin or eyes, which can signal liver injury. These are emergencies regardless of what a hormone test says.

Men already on prescribed testosterone should contact their prescriber, not stop the medicine, if they develop any of the symptoms above or if routine blood work shows a rising hematocrit or PSA. Any change to a prescribed hormone, including pausing it, belongs to the clinician who prescribed it.

Finally, if a high result arrives in a man who takes nothing and feels well, the right next step is still a conversation. Rare causes are rare, but they are findable, and a clinician can decide whether imaging or specialist referral is needed. The goal of that visit is not to lower a number; it is to understand where the number came from.

Frequently asked questions

What happens when testosterone is high in males?

The brain reduces its own signals to the testicles, part of the hormone converts to estrogen, and bone marrow makes more red blood cells. In practice that can mean smaller testicles and lower sperm counts, acne, enlarged male breast tissue (gynecomastia), thickened blood and higher blood pressure, particularly when the hormone comes from steroids or unsupervised products. Natural high-normal levels usually produce none of these changes.

How can a man tell if he has high testosterone?

Only a blood test can tell. Men with naturally high and average levels look and behave alike, so appearance, voice or confidence are not indicators. A total testosterone drawn between roughly 7 and 10 a.m., repeated if abnormal and ideally paired with free testosterone and SHBG, is the standard approach. Symptoms like new adult acne or breast tenderness are reasons to test, not proof.

Is it better to have high or low testosterone?

Neither; a stable level inside the normal range is the goal. Confirmed low testosterone is linked with fatigue, low libido, bone loss and anemia, while levels pushed above the natural ceiling bring thickened blood, reproductive shutdown and cardiovascular strain. Within the normal range, trials have not shown that men at the top are stronger, sharper or happier than men in the middle.

How do you fix high testosterone in men?

You address the cause rather than the number. If a prescribed product is responsible, the prescribing clinician adjusts monitoring or the regimen; if anabolic steroids are involved, a supervised medical path away from them is safest. A confirmed natural elevation is evaluated for rare testicular or adrenal causes, which specialists manage. Never stop or change a prescribed hormone on your own.

What are the signs of high testosterone in men?

The signs with real clinical backing are adult-onset acne, oily skin, faster male-pattern hair loss, enlarged or tender male breast tissue, smaller testicles, fertility difficulty, irritability and poor sleep. Hidden signs include raised hematocrit, higher blood pressure and lower HDL cholesterol on blood tests. Most appear with external hormone sources, not with naturally high-normal levels.

What causes high testosterone in men?

External sources top the list: prescribed testosterone, anabolic steroids and supplements containing undeclared hormones. Rarer natural causes include testosterone-producing tumors of the testicles or adrenal glands, congenital adrenal hyperplasia, and precocious puberty in boys. Some conditions, such as hyperthyroidism, raise SHBG and inflate the total reading while free, active testosterone stays normal.

Is high testosterone bad for men?

It depends on the source. A naturally high-normal level in a healthy man has only weak observational evidence of harm and is generally considered a trait, not a condition. Levels pushed above the natural range by steroids or unsupervised products are consistently linked to thickened blood, blood clots, high blood pressure, infertility and mood disturbance, with evidence that clinicians regard as well established.

What are typical high testosterone symptoms in a male on steroids?

Acne across the back and shoulders, testicular shrinkage, enlarged male breast tissue, fluid retention, rapid muscle gain, irritability or aggression, insomnia and, with oral compounds, signs of liver strain. Blood tests often show very high testosterone with a suppressed LH, raised hematocrit and reduced HDL. These effects are documented by NIDA and the NHS as recognized consequences of anabolic steroid misuse.

Does high testosterone weaken the immune system?

The evidence is suggestive but not conclusive. Laboratory studies show testosterone dampens some immune pathways, and a few observational studies have linked higher levels with weaker antibody responses to vaccines. No randomized trial has shown that men with higher natural testosterone get more infections in daily life. Treat this as an open research question rather than an established risk.

Does high testosterone cause prostate cancer?

Large observational studies have not shown that higher natural testosterone raises prostate cancer risk, and the recent TRAVERSE trial did not find more prostate cancer in men treated with testosterone over several years. Prostate screening decisions follow age- and risk-based guidance that a clinician applies to your situation; a testosterone result on its own does not change that approach.
