Voor een man met bevestigd testosterondeficit is de behandeling effectief: ze verhoogt betrouwbaar de seksuele lust, verlicht depressieve symptomen enigszins en bouwt botdichtheid op. Deficit betekent symptomen in combinatie met een laag niveau dat is bevestigd door ochtendbloedtests die op twee aparte dagen zijn herhaald; dit is een smaller groep dan wat de marketing suggereert. Bij de meeste mannen daalt het testosteron vanaf de middelbare leeftijd met ongeveer één procent per jaar, en dat langzame verval is normale veroudering, geen ziekte die moet worden gecorrigeerd.
De afwegingen zijn specifiek: testosteron maakt het bloed dikker en vereist monitoring, het stopt de eigen spermproductie van een man waardoor het de verkeerde keuze is voor iedereen die kinderen wil, en zodra de testikels rustig worden blijven de meeste mannen er levenslang op. In de grote TRAVERSE-veiligheidstest verhoogde het geen belangrijke hartgebeurtenissen, hoewel het wel atriumfibrilleren, longembolieën (bloedstolsels in de longen) en nierbeschadiging verhoogde. Voor de meeste mannen zijn de eerste hefbomen om testosteron te verhogen: overtollig gewicht verliezen, slaap beschermen, slaapapneu behandelen, weerstandstraining doen en minder alcohol consumeren, en of er behandeling aan toegevoegd moet worden is een beslissing die wordt genomen met een clinician op basis van bevestigde waarden.

What It Is
Testosterone is the main male sex hormone, made mostly in the testes on a signal from the brain. It drives sex drive and erections, maintains muscle and bone, supports red-blood-cell production, and is one part of making sperm. From midlife the level drifts down about 1 percent a year, ordinary aging rather than a disease to correct, as the Endocrine Society frames it.
That same 2018 guideline reserves the diagnosis, hypogonadism, for clear symptoms alongside a low level confirmed on morning tests taken on two separate days. The symptoms are low sex drive, poor morning erections, loss of body hair, or shrinking testes. Many low readings also come with a big waistline, poor sleep, sleep apnea, or heavy drinking. In those men the low level is often a consequence, and it recovers as the weight comes down. Low-T clinics, by contrast, treat broadly on loose criteria.
What It Does
In the Testosterone Trials, a coordinated set of studies in men 65 and older whose levels were confirmed under 275 ng/dL, a year of treatment raised testosterone into the mid-normal range and sorted the results into three tiers. Sexual desire and activity rose clearly. Mood and bone density lifted a little. Energy, walking distance, and memory did not measurably change. Snyder and colleagues reported the set in the New England Journal of Medicine in 2016.

Heart And Vascular
In 5,246 men at cardiac risk, testosterone did not raise major cardiac events (7.0% vs 7.3%)
In a large trial of men at cardiovascular risk, testosterone did not increase heart attacks, strokes or cardiac deaths compared with placebo.
The TRAVERSE trial randomized 5,246 men aged 45 to 80 with hypogonadism and either existing or high risk of cardiovascular disease to testosterone gel or placebo. A primary cardiac event occurred in 7.0% on testosterone and 7.3% on placebo (hazard ratio 0.96, 95% CI 0.78 to 1.17), meeting the pre-set non-inferiority margin over a mean follow-up of about three years. Measured in: 5,246 men aged 45 to 80 with symptomatic hypogonadism and pre-existing or high risk of cardiovascular disease.. Non-inferiority is a ceiling on added risk, not a benefit, and the same trial found more atrial fibrillation, acute kidney injury and pulmonary embolism on testosterone, so the reassurance about major cardiac events sits alongside these specific signals.
Who this may not transfer to:Measured in men with hypogonadism and cardiovascular risk; being male-specific it does not transfer to women.

Testosterone increased soft coronary plaque by about 41 mm3 over one year
Over a year, men on testosterone built up more soft plaque in their heart arteries than men on placebo.
In a coronary-imaging substudy of the Testosterone Trials, 138 men aged 65 and older completed CT angiography before and after one year of treatment. Testosterone was associated with a significantly greater increase in noncalcified coronary plaque volume than placebo (estimated difference 41 mm3, 95% CI 14 to 67; P=0.003) and in total plaque volume (difference 47 mm3, 95% CI 13 to 80). Measured in: 138 men aged 65 and older with an average of two testosterone readings under 275 ng/dL who completed coronary CT angiography at baseline and one year.. This is a surrogate imaging outcome in a small group over one year, and it was not accompanied by more cardiac events in this study or in the much larger TRAVERSE trial, so its clinical meaning is unsettled.
Who this may not transfer to:Measured in older men with confirmed low testosterone; being male-specific it does not transfer to women.

Sexual Function
Testosteron verbeterde 10 van de 12 maten van seksuele activiteit bij oudere mannen met lage waarden
Bij oudere mannen met een laag testosteron en een laag libido gaf de behandeling een matige boost aan seksueel verlangen en activiteit.
In de Sexual Function Trial van de Testosterone Trials werden 470 mannen van 65 jaar en ouder met een laag libido en een gemiddeld testosteron onder 275 ng/dL gerandomiseerd naar testosterongel of placebo gedurende één jaar. Testosteron verbeterde significant 10 van de 12 maten van seksuele activiteit, samen met seksueel verlangen en erectiefunctie, en de omvang van de verbetering volgde de stijging van testosteron en estradiol, zonder enige enkele drempelwaarde te overschrijden. Measured in: 470 men aged 65 and older with low libido, average testosterone under 275 ng/dL, and a partner willing to have intercourse at least twice a month.. De winsten waren het duidelijkst voor verlangen en algehele seksuele activiteit en zwakker voor erectiefunctie specifiek, en de studie liep één jaar bij mannen met bevestigde lage waarden, dus het spreekt niet tot mannen wier testosteron normaal is.
Who this may not transfer to:Testosterone therapy for male hypogonadism is male-specific, so the finding does not transfer to women. It was measured in older men with confirmed low levels, not in men with normal testosterone.

Gepoolde studies tonen dat testosteron seksueel verlangen en erectiefunctie verbeterde bij mannen met lage waarden
Bij het poolen van de studies verbeterde testosteronbehandeling het libido en de erecties bij mannen met bevestigde lage waarden, en het verhoogde ook de kans dat het bloed te dik werd.
Een systematische review en meta-analyse van gerandomiseerde, placebogecontroleerde studies vond dat testosteronvervangingstherapie bij hypogonadale mannen het seksuele verlangen, de erectiefunctie en de seksuele tevredenheid verbeterde vergeleken met placebo, terwijl het ook het risico op erytrocytose, een verdikking van het bloed, verhoogde. Measured in: Hypogonadal men enrolled in randomized, placebo-controlled trials of testosterone replacement therapy, pooled across studies.. De verbeteringen zijn bescheiden gemiddelden en de samenstellende studies waren grotendeels kort, dus de meta-analyse meet symptoomverandering over maanden, niet jaren, en kan langetermijnvoordeel of -schade niet beantwoorden.
Who this may not transfer to:The pooled trials enrolled only hypogonadal men, so the finding is male-specific and does not transfer to women or to men with normal testosterone.

Energy And Fatigue
Testosteron gaf geen meetbare winst in energie of loopafstand bij oudere mannen met lage waarden
Testosteron verbeterde energie of loopafstand niet merkbaar, ook al hielp het hun seksualiteit.
In de Testosterone Trials gaf het verhogen van testosteron naar het midden-normale bereik gedurende één jaar bij symptomatische mannen van 65 jaar en ouder geen significant voordeel voor vitaliteit op de FACIT-Vermoeidheidsschaal, en verhoogde het niet het aandeel mannen dat minstens 164 ft (50 meter) verder liep in zes minuten binnen de eigen populatie van de Physical Function Trial. Seksuele functie verbeterde en stemming verbeterde licht. Measured in: 790 men aged 65 and older with an average of two testosterone readings under 275 ng/dL and symptoms of low testosterone, across the seven coordinated Testosterone Trials.. Een gepoolde analyse over alle drie de armen toonde wel een kleine voorsprong in de zes-minuten-wandeling, dus het nulresultaat geldt voor de primaire lichamelijke-functie-populatie van de studie, niet voor elke mogelijke lezing van de gegevens, en de studie duurde één jaar.
Who this may not transfer to:Measured in older men with confirmed low testosterone; being male-specific it does not transfer to women, and the null speaks to vitality and walking, not to sexual function, which did improve.

Mood & stress
Across 27 trials, testosterone produced a small drop in depressive symptoms in men
Over de studies heen verlichtte testosteron depressieve symptomen met een kleine hoeveelheid vergeleken met placebo.
Een random-effectsmeta-analyse van 27 gerandomiseerde, placebogecontroleerde studies bij 1,890 mannen vond dat testosteronbehandeling werd geassocieerd met een kleine maar significante vermindering van depressieve symptomen vergeleken met placebo (Hedges g 0.21, 95%-BI 0.10 tot 0.32), met grotere effecten bij hogere doses en in meer zorgvuldig geselecteerde steekproeven. Measured in: 1,890 men across 27 randomized placebo-controlled trials, spanning hypogonadal and eugonadal men reporting depressive symptoms on validated scales.. The effect is small and the trials were heterogeneous, few examined depression as their main outcome, and the benefit was most reliable at higher doses, so this is a signal in symptom scores, not an established treatment for depression.
Who this may not transfer to:The meta-analysis pooled trials in men only, so the finding is male-specific and does not transfer to women.

Cognition
A year of testosterone did nothing measurable for memory in older men with low levels
A year of testosterone did nothing measurable for memory or thinking in older men with low levels and memory complaints.
In the Cognitive Function Trial of the Testosterone Trials, 493 men aged 65 and older with low testosterone and age-associated memory impairment showed no significant change in delayed paragraph recall after one year of testosterone versus placebo (adjusted difference -0.07, 95% CI -0.92 to 0.79), and no benefit for visual memory, executive function or spatial ability. Measured in: 493 men aged 65 and older with low testosterone and age-associated memory impairment, randomized to testosterone gel or placebo for one year.. The trial ran for one year in men who already had memory complaints, so it does not address whether very long-term treatment or other populations would differ, but within its design the null was consistent across every cognitive measure.
Who this may not transfer to:Measured in older men with low testosterone and memory impairment; being male-specific it does not transfer to women.

Bone Density
Testosterone raised spine bone density about 7.5% in a year in older men with low levels
A year of testosterone measurably increased spine and hip bone density and estimated bone strength.
In the Bone Trial of the Testosterone Trials, 211 men aged 65 and older with low testosterone had a significantly greater rise in spine trabecular volumetric bone density on testosterone than placebo over one year (7.5% vs 0.8%; treatment effect 6.8%, 95% CI 4.8 to 8.7), with estimated spine bone strength rising 10.8% versus 2.4%, and gains also seen at the hip. Measured in: 211 men aged 65 and older with an average of two testosterone readings under 275 ng/dL, randomized to testosterone gel or placebo for one year.. The trial measured bone density and calculated strength, not fractures, so whether the density gain would translate into fewer broken bones was left for a larger, longer study to answer.
Who this may not transfer to:Measured in older men with confirmed low testosterone; being male-specific it does not transfer to women, whose bone loss is driven mainly by estrogen.

Fertility
Testosterone shuts down sperm production, often to zero, while a man is on it
Taking testosterone switches off the body's own signal to the testes, so sperm production drops, often to nothing, while a man is on it.
Giving testosterone from outside shuts down the pituitary signals (LH and FSH) that drive the testes, which collapses the testosterone concentration inside the testis needed for sperm production. The result is a sharp fall in sperm count, often to zero, which is why exogenous testosterone is described as a preventable cause of male infertility and is not given to men trying to conceive. Measured in: Men receiving exogenous testosterone, reviewed across the andrology and male-fertility literature.. Suppression is usually reversible after stopping, but recovery can take months to more than a year and is not guaranteed in every man, so it cannot be treated as risk-free for someone who wants children.
Who this may not transfer to:This concerns male spermatogenesis and is male-specific, so it does not transfer to women.

Measurement And Diagnosis
Diagnosing low testosterone needs symptoms plus a low level confirmed on two morning tests
Low testosterone is diagnosed from symptoms plus a low level confirmed on two morning blood tests, not from a single reading or tiredness alone.
The Endocrine Society clinical practice guideline recommends diagnosing hypogonadism only in men who have both symptoms of testosterone deficiency and unequivocally low morning fasting total testosterone, confirmed on at least two separate mornings, since levels are highest in the morning and fall with acute illness. It recommends against starting testosterone in men planning fertility in the near term. Measured in: Adult men, as addressed by an Endocrine Society clinical practice guideline synthesizing the evidence and expert consensus.. This is a guideline recommendation reflecting expert consensus and graded evidence, not a single trial, and testosterone assays and reference ranges vary between laboratories, which is part of why repeat morning testing matters.
Who this may not transfer to:The guideline addresses male hypogonadism specifically, so the diagnostic criteria do not transfer to women.

Progress Markers
Gewichtsverlies verhoogde testosteron, ongeveer 2.9 nmol/L door dieet en 8.7 door chirurgie
Gewichtsverlies verhoogde het testosteron bij mannen, en hoe meer gewicht een man verloor, hoe meer het steeg.
Een meta-analyse van 24 studies vond dat gewichtsverlies het totale testosteron bij mannen verhoogde, waarbij een laagcalorisch dieet het met ongeveer 2.9 nmol/L verhoogde en bariatrische chirurgie met ongeveer 8.7 nmol/L, beide significant ten opzichte van de uitgangswaarde. De stijging was groter bij mannen die meer gewicht verloren en bij jongere, meer obese, niet-diabetische mannen, wat wijst op gewicht zelf als drijfveer van de lage waarden. Measured in: Men in 24 studies of diet-based weight loss or bariatric surgery, with testosterone measured before and after weight loss.. De meeste dietststudies waren ongecontroleerde voor-en-na-vergelijkingen, geen gerandomiseerde studies, dus het effect is goed gerepliceerd maar de omvang voor een individu hangt sterk af van hoeveel gewicht er wordt verloren.
Who this may not transfer to:The analysis addressed testosterone in men losing weight, so this male-specific finding does not transfer to women.

Weight And Fat Loss
Over 29 trials verlaagde testosteron de vetmassa met 1.6 kg en voegde 1.6 kg vetvrije massa toe, zonder gewichtsverandering
Pooling 29 trials in men, testosterone shifted body composition, not total weight: it removed about 1.6 kg of fat and added about 1.6 kg of lean mass, so the scale held steady while the ratio of muscle to fat improved. Strength barely changed, so the added muscle shows up on a body scan more than in what a man can lift.
A meta-analysis of 29 randomized controlled trials in 1,083 middle-aged and older men (mean age 64.5, mean testosterone 10.9 nmol/L) found that testosterone treatment reduced total body fat by 1.6 kg (95% CI -2.5 to -0.6), about a 6.2% fall from baseline fat, and increased fat-free (lean) mass by 1.6 kg (95% CI 0.6 to 2.6), about a 2.7% rise, with no change in overall body weight. The effect on muscle strength was heterogeneous, with only a tendency toward improvement at leg extension and dominant-hand grip. Measured in: 1,083 middle-aged and older men across 29 randomized controlled trials, mean age 64.5 years and mean baseline testosterone 10.9 nmol/L, randomized to testosterone or placebo.. De lichaamssamenstellingsverandering is consistent over trials, maar het is een verschuiving in de spier-vetverhouding, geen gewichtsverlies, en het ging niet gepaard met een duidelijke krachttoename, dus het moet niet worden gelezen als een functioneel of fitnessvoordeel op zichzelf.
Who this may not transfer to:The trials enrolled only men and measured the response to male testosterone therapy, so this male-specific finding does not transfer to women.

Sleep
Een week korte slaap verlaagde het overdag-testosteron van jonge mannen met 10 tot 15%
Toen gezonde jonge mannen slechts vijf uur per nacht sliepen gedurende een week, daalde hun overdag-testosteron met 10 tot 15%.
In een gecontroleerde slaapstudie werden 10 gezonde jonge mannen gedurende één week beperkt tot vijf uur slaap per nacht na een uitgangsperiode van volledige slaap. Hun overdag-testosteron daalde met 10 tot 15%, met de laagste waarden in de middag en avond, wat aantoont dat kortgesneden slaap testosteron binnen dagen onderdrukt. Measured in: 10 healthy young men studied under laboratory sleep restriction of five hours per night for one week.. Dit was een kleine, korte studie bij jonge gezonde mannen, niet bij oudere mannen of bij mannen met lage waarden, dus het toont aan dat slaapverlies testosteron verlaagt zonder het effect te kwantificeren bij de mannen die behandeling het meest zullen overwegen.
Who this may not transfer to:Measured in young men and concerning male testosterone specifically, so it does not transfer to women.

Body composition shifts more than the scale. Pooling 29 randomized trials in 1,083 middle-aged and older men, testosterone cut total body fat by about 1.6 kg, roughly 6 percent of starting fat. It added about 1.6 kg of lean mass, roughly 3 percent, with no change in overall body weight.
The Risks and Trade-offs
In the largest safety trial, testosterone did not raise major cardiac events, though it carried three narrower risks. TRAVERSE randomized 5,246 men aged 45 to 80 who had low testosterone and either heart disease or a high risk of it. Over about three years, heart attacks, strokes, and cardiac deaths were no more common than on placebo, 7.0 percent versus 7.3 percent. Lincoff and colleagues reported TRAVERSE in NEJM in 2023. The three narrower signals were more atrial fibrillation, more blood clots in the lungs, and more acute kidney injury. An earlier imaging substudy found more soft plaque in the heart arteries over a year, a surrogate whose meaning is unsettled because it was not matched by more cardiac events.
Three trade-offs shape the decision beyond the trial numbers. Testosterone thickens the blood by raising the red-cell count, so the count is checked before and during treatment. A level that climbs too high is the most common reason a dose is lowered or paused. Testosterone from outside also switches off the brain's signal to the testes, and with it a man's own sperm production, so sperm often falls to zero on treatment. Crosnoe and colleagues reported in 2013 that this suppression usually reverses after stopping, though recovery can take months to more than a year and is not guaranteed in every man. Once the testes quiet down they make less on their own, so most men who start stay on it for life. Stopping brings the low-testosterone symptoms back, often more sharply for a while.
Testosterone is the wrong choice for anyone who wants to father children in the foreseeable future.
Cautions With Testosterone Therapy
Extra restraintEverything to be aware of is here, in one place. This practice suits most healthy people; a few situations call for real care.
Testosterone raises the red-cell count and hematocrit, thickening the blood
A systematic review and meta-analysis of randomized trials found that testosterone therapy in men increased hemoglobin and hematocrit and produced a small decrease in HDL cholesterol compared with placebo. The rise in red-cell concentration is the basis for routine hematocrit monitoring before and during treatment. The review graded the evidence on patient-important outcomes as low quality with brief follow-up, so it establishes the blood-count effect clearly while leaving the downstream consequences, such as clots, less well quantified.Fernandez-Balsells et al., Clinical review 1: Adverse effects of testosterone therapy in adult men: a systematic review and meta-analysis
The prostate is checked before and during treatment
Testosterone does not appear to cause prostate cancer, but it can speed the growth of one already present, so a PSA blood test and examination are done before starting and repeated on treatment. New or worsening urinary symptoms, or a family history of prostate cancer, are reasons to have this settled first.
Testosterone bought online or from a gym skips the monitoring that makes it safe
The blood-count and prostate checks are the safety net. Testosterone obtained without them, or a dose pushed ever higher to chase an effect, carries the risks of treatment without the guardrails.
Over-the-counter "testosterone boosters" are not treatment
These supplements are unregulated and rarely raise testosterone in any measurable way. A confirmed low level is treated by prescription, and a normal level does not need raising.
For the man with a confirmed low level and clear symptoms, testosterone therapy is a well-studied treatment that helps. For most men the more useful work is the sleep, the weight, the training and the drink, which raise testosterone without the trade-offs. Whether to add treatment, and any change to it, is a conversation with the clinician who can see your numbers.
When to See Someone
Most questions about testosterone are worked out calmly with a clinician and a morning blood test, and the natural levers are yours to start today. These are the signs and situations worth acting on rather than self-managing:
- A very low testosterone reading with headaches, changes in vision, or milky nipple discharge, which can point to a pituitary problem and needs prompt assessment.(seek urgent care)
- Testicles that are small, shrinking, or newly hard or lumpy, or breast tissue that is growing or tender, which need a doctor rather than a testosterone prescription.
- Symptoms of deficiency, low sex drive, loss of morning erections, loss of body hair, which are worth confirming with a morning fasting testosterone repeated on two separate days before anything is started.
- Any plan to father children now or later, since testosterone therapy suppresses sperm production; raise fertility before starting, because the right treatment is a different one.(seek urgent care)
- Already on testosterone with a headache, unusual flushing, or leg swelling, calf pain or breathlessness, which can signal blood that has grown too thick or a clot and needs same-day care.(seek urgent care)
None of this is meant to alarm you. For the man with a confirmed low level and clear symptoms, testosterone therapy is a well-studied treatment that helps. For most men the more useful work is the sleep, the weight, the training and the drink, which raise testosterone without the trade-offs. Whether to add treatment, and any change to it, is a conversation with the clinician who can see your numbers, which is exactly where it belongs.
Raise It Naturally First
Losing excess weight raises testosterone directly, and the more a man loses the more it climbs. In Corona's 2013 pooled analysis a low-calorie diet added about 2.9 nmol/L and bariatric surgery about 8.7. Four more levers stack on top, none of them needs money or a clinic, and a man who cannot afford lab testing can start every one today.
- Protect your sleep. Testosterone is made largely while you sleep. Cutting healthy young men to 5 hours a night for a week dropped their daytime levels 10 to 15 percent (Leproult and Van Cauter, JAMA, 2011).
- Get sleep apnea treated. In heavier men it is a common, correctable drag on testosterone. Loud snoring with witnessed pauses in breathing is the sign worth checking.
- Lift weights. Resistance training supports testosterone alongside muscle and bone, and it is free once the movements are learned.
- Ease back on alcohol. Cutting down lifts a common, reversible cause of low readings, and it helps sleep and weight at the same time.
Go Deeper

The Chinese Medicine View
For thousands of years Chinese medicine has tied a man's vigor, warmth, and morning drive to the Kidney, and it groups the fading of all three under Kidney Yang.
The Chinese Medicine View
Chinese medicine has no measurement of testosterone; it reads the picture a man presents, the drive, the warmth, the vigor of the low back and knees, and it locates the reproductive fire in the Kidney. The classical language of Kidney Yang, of Ming men fire (the life-gate fire that warms the whole body), and of Jing (the deep essence that ages with us) maps loosely onto what a modern clinic calls low testosterone, and reading it as a lens on the man can be useful. It is a lens, not a measurement, and it makes no claim on what a hormone does. Chinese medicine would also caution here: warming Kidney-Yang tonics suit the cold, depleted picture and are the wrong direction for a man who runs hot and congested with Damp-Heat, and the herbal 'testosterone' and 'male vitality' products sold direct to the public have a documented record of being spiked with undeclared drugs, so authentic herbs belong with a qualified practitioner and a traceable supply.
Low drive, cold limbs, a sore and weak lower back and knees, tiredness that deepens in winter, and low drive rather than agitation. The classical direction is to warm and tonify Kidney Yang. This is the cold, depleted picture where warming tonics were traditionally reserved, and it maps loosely onto the older man with a confirmed low level.
The life-gate fire seen as burning low: deep fatigue, poor morning vigor, feeling the cold, loose stools before dawn. Chinese medicine reads this as the root warmth of the body fading, and works to rekindle it gently rather than force it.
Premature aging, night sweats, tinnitus, dryness and low reserves, the essence running down rather than the fire going cold. Here the direction is to nourish Jing and Yin, and adding more heat would be the wrong move, which is why the pattern matters before any tonic is chosen.
A heavier, richer-living man with a hot, congested, heavy feeling below, a bitter taste and dark scanty urine. Chinese medicine clears Damp-Heat here and would caution plainly against the warming Yang tonics that suit the deficient patterns, since they would feed the heat.
Common Questions
Does testosterone build strength a man can actually use?
Only a little. Across the pooled trials, grip and leg strength barely moved, so the added lean mass shows on a body scan more than in the weight a man can lift.
Why does the blood test have to be in the morning?
Testosterone runs highest in the early hours and falls through the day, so an afternoon draw, or one taken during an illness, reads falsely low. That is why a meaningful reading is drawn early and repeated to confirm it.
