Pour un homme présentant un déficit en testostérone confirmé, le traitement est efficace : il augmente de façon fiable le désir sexuel, atténue un peu les symptômes dépressifs et renforce la densité osseuse. Le déficit signifie des symptômes associés à un taux bas confirmé par des analyses de sang matinales répétées deux jours distincts, ce qui représente un groupe plus restreint que ne le suggère le marketing. La testostérone baisse d'environ un pour cent par an à partir de la quarantaine chez la plupart des hommes, et cette lente dérive est un vieillissement normal, non une maladie à corriger.
Les compromis sont précis : la testostérone épaissit le sang et nécessite une surveillance, elle interrompt la production de spermatozoïdes de l'homme, ce qui en fait un mauvais choix pour quiconque souhaite avoir des enfants, et une fois les testicules mis au repos, la plupart des hommes en prennent à vie. Dans le grand essai de sécurité TRAVERSE, elle n'a pas augmenté les événements cardiaques majeurs, bien qu'elle ait augmenté la fibrillation atriale, les caillots sanguins dans les poumons et les lésions rénales. Pour la plupart des hommes, les leviers qui élèvent d'abord la testostérone sont la perte de surpoids, la protection du sommeil, le traitement de l'apnée du sommeil, la musculation et la réduction de l'alcool, et la décision d'ajouter un traitement se prend avec un clinicien sur la base de chiffres confirmés.

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
Chez 5,246 hommes à risque cardiaque, la testostérone n'a pas augmenté les événements cardiaques majeurs (7.0 % contre 7.3 %)
Dans un vaste essai portant sur des hommes à risque cardiovasculaire, la testostérone n'a pas augmenté les crises cardiaques, les accidents vasculaires cérébraux ni les décès cardiaques par rapport au placebo.
L'essai TRAVERSE a randomisé 5,246 hommes de 45 à 80 ans présentant un hypogonadisme et un risque existant ou élevé de maladie cardiovasculaire pour recevoir un gel de testostérone ou un placebo. Un événement cardiaque primaire est survenu chez 7.0 % sous testostérone et 7.3 % sous placebo (rapport de risque 0.96, IC à 95 % 0.78 à 1.17), atteignant la marge de non-infériorité prédéfinie sur un suivi moyen d'environ trois ans. Measured in: 5,246 men aged 45 to 80 with symptomatic hypogonadism and pre-existing or high risk of cardiovascular disease.. La non-infériorité est un plafond sur le risque ajouté, pas un bénéfice, et le même essai a constaté davantage de fibrillation auriculaire, d'insuffisance rénale aiguë et d'embolie pulmonaire sous testostérone ; le rassurement concernant les événements cardiaques majeurs coexiste donc avec ces signaux spécifiques.

La testostérone a augmenté la plaque coronarienne molle d'environ 41 mm3 sur un an
Sur un an, les hommes sous testostérone ont accumulé davantage de plaque molle dans leurs artères coronaires que les hommes sous placebo.
Dans une sous-étude d'imagerie coronarienne des Testosterone Trials, 138 hommes de 65 ans ou plus ont réalisé une angiographie par TDM avant et après un an de traitement. La testostérone a été associée à une augmentation significativement plus importante du volume de plaque coronarienne non calcifiée que le placebo (différence estimée 41 mm3, IC à 95 % 14 à 67 ; P=0.003) et du volume total de plaque (différence 47 mm3, IC à 95 % 13 à 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.. Il s'agit d'un critère d'imagerie de substitution dans un petit groupe sur un an, et il n'a pas été accompagné d'une augmentation des événements cardiaques dans cette étude ni dans l'essai TRAVERSE, bien plus vaste ; sa signification clinique reste donc incertaine.

Sexual Function
Testosterone improved 10 of 12 measures of sexual activity in older men with low levels
In older men with low testosterone and low sex drive, treatment gave a moderate lift to sexual desire and activity.
In the Sexual Function Trial of the Testosterone Trials, 470 men aged 65 or older with low libido and an average testosterone below 275 ng/dL were randomized to testosterone gel or placebo for one year. Testosterone significantly improved 10 of 12 measures of sexual activity, along with sexual desire and erectile function, and the size of the improvement tracked the rise in testosterone and estradiol, not crossing any single threshold. 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.. The gains were clearest for desire and overall sexual activity and weaker for erectile function specifically, and the trial ran for one year in men with confirmed low levels, so it does not speak to men whose testosterone is normal.
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.

Pooled trials show testosterone improved sexual desire and erectile function in men with low levels
Pooling the trials, testosterone treatment improved sex drive and erections in men with confirmed low levels, and it also raised the chance of the blood growing too thick.
A systematic review and meta-analysis of randomized, placebo-controlled trials found that in hypogonadal men testosterone replacement therapy improved sexual desire, erectile function and sexual satisfaction compared with placebo, while also increasing the risk of erythrocytosis, a thickening of the blood. Measured in: Hypogonadal men enrolled in randomized, placebo-controlled trials of testosterone replacement therapy, pooled across studies.. The improvements are modest averages and the constituent trials were mostly short, so the meta-analysis measures symptom change over months, not years and cannot settle long-term benefit or harm.
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
La testostérone n'a apporté aucun gain mesurable d'énergie ou de distance de marche chez les hommes âgés présentant de faibles taux
Testosterone did not measurably improve energy or how far men could walk, even though it helped their sex lives.
In the Testosterone Trials, raising testosterone to the mid-normal range for one year in symptomatic men aged 65 and older gave no significant benefit for vitality on the FACIT-Fatigue scale, and did not increase the share of men walking at least 164 feet (50 meters) further in six minutes within the Physical Function Trial's own population. Sexual function improved and mood improved slightly. 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.. Une analyse regroupée des trois bras a bien montré un léger avantage au test de marche de six minutes ; le résultat nul concerne donc la population du critère principal de fonction physique de l'essai, et non toute lecture possible des données, et l'étude a duré un an.
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
Sur 27 essais, la testostérone a produit une légère diminution des symptômes dépressifs chez les hommes
Dans l'ensemble des essais, la testostérone a atténué les symptômes dépressifs dans une faible mesure par rapport au placebo.
Une méta-analyse à effets aléatoires portant sur 27 essais randomisés contrôlés contre placebo, incluant 1,890 hommes, a révélé que le traitement par testostérone était associé à une réduction faible mais significative des symptômes dépressifs par rapport au placebo (Hedges g 0.21, IC à 95 % 0.10 à 0.32), avec des effets plus marqués à doses plus élevées et dans des échantillons sélectionnés plus rigoureusement. Measured in: 1,890 men across 27 randomized placebo-controlled trials, spanning hypogonadal and eugonadal men reporting depressive symptoms on validated scales.. L'effet est faible et les essais étaient hétérogènes, peu d'entre eux examinaient la dépression comme critère principal, et le bénéfice était le plus fiable à doses plus élevées ; il s'agit donc d'un signal dans les scores de symptômes, et non d'un traitement établi de la dépression.

Cognition
Un an de testostérone n'a produit aucun changement mesurable sur la mémoire chez les hommes âgés présentant de faibles taux
Un an de testostérone n'a produit aucun changement mesurable sur la mémoire ou la cognition chez les hommes âgés présentant de faibles taux et des plaintes mnésiques.
Dans le Cognitive Function Trial des Testosterone Trials, 493 hommes de 65 ans ou plus présentant un faible taux de testostérone et une altération mnésique liée à l'âge n'ont montré aucun changement significatif du rappel différé de paragraphes après un an de testostérone versus placebo (différence ajustée -0.07, IC à 95 % -0.92 à 0.79), et aucun bénéfice pour la mémoire visuelle, la fonction exécutive ou les capacités spatiales. 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.. L'essai a duré un an chez des hommes présentant déjà des plaintes mnésiques ; il ne permet donc pas de déterminer si un traitement à très long terme ou d'autres populations donneraient des résultats différents, mais dans le cadre de son protocole, le résultat nul était cohérent sur toutes les mesures cognitives.

Bone Density
La testostérone a augmenté la densité osseuse de la colonne vertébrale d'environ 7.5 % en un an chez les hommes âgés présentant de faibles taux
Un an de testostérone a augmenté de façon mesurable la densité osseuse de la colonne vertébrale et de la hanche ainsi que la résistance osseuse estimée.
Dans le Bone Trial des Testosterone Trials, 211 hommes de 65 ans ou plus présentant un faible taux de testostérone ont connu une augmentation significativement plus importante de la densité osseuse volumétrique trabéculaire de la colonne vertébrale sous testostérone que sous placebo sur un an (7.5 % contre 0.8 % ; effet du traitement 6.8 %, IC à 95 % 4.8 à 8.7), avec une résistance osseuse estimée de la colonne vertébrale en hausse de 10.8 % contre 2.4 %, et des gains également observés au niveau de la hanche. 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.. L'essai a mesuré la densité osseuse et calculé la résistance, pas les fractures ; la question de savoir si le gain de densité se traduirait par moins de fractures a donc été laissée à une étude plus vaste et plus longue.

Fertility
La testostérone bloque la production de spermatozoïdes, souvent jusqu'à zéro, tant que l'homme en prend
La prise de testostérone coupe le signal propre de l'organisme vers les testicules, ce qui fait chuter la production de spermatozoïdes, souvent jusqu'à zéro, tant que l'homme en prend.
L'administration de testostérone provenant de l'extérieur bloque les signaux hypophysaires (LH et FSH) qui stimulent les testicules, ce qui effondre la concentration de testostérone intratesticulaire nécessaire à la production de spermatozoïdes. Il en résulte une chute marquée du nombre de spermatozoïdes, souvent jusqu'à zéro, raison pour laquelle la testostérone exogène est décrite comme une cause évitable d'infertilité masculine et n'est pas administrée aux hommes qui cherchent à concevoir. Measured in: Men receiving exogenous testosterone, reviewed across the andrology and male-fertility literature.. La suppression est généralement réversible après l'arrêt, mais la récupération peut prendre de plusieurs mois à plus d'un an et n'est pas garantie chez tous les hommes ; elle ne peut donc pas être considérée comme sans risque pour un homme souhaitant avoir des enfants.
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
Weight loss raised testosterone, about 2.9 nmol/L by diet and 8.7 by surgery
Losing weight raised men's testosterone, and the more weight a man lost the more it rose.
A meta-analysis of 24 studies found that losing weight raised total testosterone in men, with a low-calorie diet increasing it by about 2.9 nmol/L and bariatric surgery by about 8.7 nmol/L, both significant against baseline. The rise was larger in men who lost more weight and in younger, more obese, non-diabetic men, pointing to weight itself as a driver of the low levels. Measured in: Men in 24 studies of diet-based weight loss or bariatric surgery, with testosterone measured before and after weight loss.. Most of the diet studies were uncontrolled before-and-after comparisons, not randomized trials, so the effect is well replicated but the magnitude for any individual depends heavily on how much weight is lost.
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
Across 29 trials, testosterone cut fat mass by 1.6 kg and added 1.6 kg of lean mass, with no weight change
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.. The body-composition change is consistent across trials, but it is a shift in the muscle-to-fat ratio, not weight loss, and it was not matched by a clear gain in strength, so it should not be read as a functional or fitness benefit on its own.
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
A week of short sleep cut young men's daytime testosterone 10 to 15%
When healthy young men slept only five hours a night for a week, their daytime testosterone dropped by 10 to 15%.
In a controlled sleep study, 10 healthy young men were restricted to five hours of sleep a night for one week after a baseline of full sleep. Their daytime testosterone fell by 10 to 15%, with the lowest levels in the afternoon and evening, showing that curtailed sleep suppresses testosterone within days. Measured in: 10 healthy young men studied under laboratory sleep restriction of five hours per night for one week.. This was a small, short study in young healthy men, not in older men or those with low levels, so it demonstrates that sleep loss lowers testosterone without quantifying the effect across the men most likely to be considering treatment.
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.
La testostérone augmente le nombre de globules rouges et l'hématocrite, épaississant le sang
Une revue systématique et méta-analyse d'essais randomisés a révélé que le traitement par testostérone chez les hommes augmentait l'hémoglobine et l'hématocrite et entraînait une légère baisse du cholestérol HDL par rapport au placebo. L'augmentation de la concentration de globules rouges est à la base de la surveillance systématique de l'hématocrite avant et pendant le traitement. La revue a jugé la qualité des preuves sur les critères importants pour les patients comme faible, avec un suivi bref ; elle établit donc clairement l'effet sur la numération sanguine tout en laissant les conséquences en aval, telles que les caillots, moins bien quantifiées.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.
