Recognize When Low Testosterone Needs Evaluation
Tiredness, a lower sex drive and a flat mood are common in men, and they have many causes, so the real goal is knowing which pattern is worth a proper check. This page is about spotting that pattern, preparing for the visit and understanding how doctors confirm or rule out low testosterone; normal age-related changes, hormone tests in general and booster products have their own pages.
General information, not medical advice. Last updated November 1, 2026. Written by the AlternativeMed editorial team. Not medically reviewed.
Start here
- Write down what you have noticed, when it started and how often (for example fewer morning erections, a lower sex drive, less energy), then book a visit with your doctor rather than trying to treat it yourself.
- Expect a blood test taken in the morning, and expect it to be repeated if the first result is low; one result on its own cannot settle the question.
- Ask the doctor to look at other common causes too, such as sleep problems, weight, medicines, alcohol, low mood and thyroid or blood-sugar problems.
Be careful with
- Do not start testosterone, anabolic steroids, SARMs or "booster" products on the strength of symptoms alone. They can harm fertility, the heart, the liver and mood, and the symptoms often have a different cause.
- Do not stop or change a prescribed medicine because you suspect it is affecting your hormones; talk to the prescriber first.
- Low mood that lasts, loss of interest in everything, or any thoughts of harming yourself need a doctor or a crisis line now, not a hormone test first.
Get help when
- Sudden severe pain in a testicle, or pain after an injury: this can be testicular torsion, which is an emergency where hours matter. Go to emergency care straight away.
- Suddenly being unable to pass urine, blood in the urine or semen, a painful or growing lump or swelling in a testicle, or fever with urinary symptoms: seek urgent medical care.
- Chest pain, fainting, new breathlessness or new palpitations, or a severe sudden headache with vision changes: seek emergency care.
- Symptoms that have lasted several weeks, keep getting worse, or come with unexplained weight loss, loud snoring with gasping at night, persistent low mood, or a plan to have a child: book a medical visit.
About Recognize When Low Testosterone Needs Evaluation
What this goal means
Testosterone is the main male sex hormone. Doctors speak of low testosterone, or male hypogonadism, only when a man has both symptoms or signs that fit it and a clearly and repeatedly low level in a blood test. The Endocrine Society guideline recommends making the diagnosis only in men with symptoms and signs consistent with deficiency and unequivocally and consistently low blood levels, and the American Urological Association guideline likewise treats a man as deficient only when both criteria are met.
This goal is about the step before treatment: noticing a pattern, deciding whether it is worth a medical check, and knowing what a sensible evaluation looks like.
1,2,3Common experiences
MedlinePlus lists low sex drive, erectile problems, infertility, enlarged breasts, reduced facial or body hair, thinning bones or unexplained anemia, and muscle loss among the signs of low testosterone in men after puberty. NHS Highland guidance names erectile dysfunction, fewer or absent early-morning erections and reduced libido as the key symptoms, with low bone density and a mild form of anemia also possible.
In a survey of 3,369 men aged 40 to 79 in eight European centres, poor morning erections, low sexual desire and erectile dysfunction were the symptoms most closely tied to a low testosterone level, and men with more of these three symptoms tended to have lower levels. Tiredness, low mood and reduced physical vigour were also linked to testosterone in that study but were not specific enough to define the condition.
4,5,6Why symptoms are not proof
The AUA notes that the symptoms are nonspecific and can reflect other conditions such as chronic fatigue, chronic stress or depression. MedlinePlus says a testosterone test alone cannot diagnose any health condition and that an abnormal result does not always mean a condition that needs treatment.
It is also normal for testosterone to decrease with age, so a lower number on its own does not mean something is wrong. What matters is the whole picture: your symptoms, repeated morning measurements and other findings.
2,4Contributing factors and other things to rule out
MedlinePlus lists testicular problems, chronic liver or kidney disease, pituitary gland disorders, benign tumors, testicular injury, alcohol use disorder and genetic conditions such as Klinefelter syndrome among causes of low levels. NHS Highland guidance adds non-gonadal illness, opiate medicines and links milder deficiency to ageing and obesity.
A meta-analysis of 24 case-control studies found lower testosterone in men with obstructive sleep apnea than in controls, although the studies differed widely and it shows an association rather than proof of cause. A meta-analysis of 24 studies found that weight loss through diet or bariatric surgery was associated with a rise in testosterone. The Endocrine Society recommends further evaluation to find the cause once deficiency is confirmed.
4,5,7,8,1Realistic expectations
Evaluation usually takes more than one visit: a conversation, a morning blood sample, a repeat sample if the first is low, and tests to find the cause. Many men who go because of these symptoms turn out to have normal levels and another explanation, which is a useful answer too.
If low testosterone is confirmed and treated, results depend on the symptom. In a one-year trial of 790 men aged 65 and over with low levels and symptoms, testosterone gel improved sexual activity, desire and erectile function, but it did not improve vitality or walking distance in the main analysis.
4,9Who this applies to
Adult men who notice a lasting change that fits the symptoms above. The Endocrine Society recommends against routinely screening men in the general population who have no symptoms, so this page is not a reason to test without a reason. Boys and teenagers, and men planning a child in the near term, need specific medical advice; see the puberty, fertility and hormone-test pages.
1Related conditions and symptoms
Sleep apnea → Thyroid and fatigue → Erectile dysfunction → Anxiety disorders → Obesity and weight-related health → Osteoporosis and bone health →
A manageable starting plan
An educational starting point, not a personal prescription. Adjust it to your own situation and any advice from your clinician.
Your first actions
- Write a short symptom list with dates, plus every medicine and supplement you take.
- Book a medical visit and ask for fasting morning testing, repeated if low, and for common look-alikes to be checked.
- Tell the doctor about any plans to have a child, snoring or gasping at night, drinking and mood.
- Do not use boosters, steroids or SARMs while you wait.
Optional additions
- Read the hormone-tests page so the results make sense.
- Start gradual, sustainable weight and sleep habits if relevant.
- Bring a partner or friend to the visit if that helps.
What to track
- Morning erections, desire, energy and mood, noted weekly for a few weeks.
- Sleep quality and any snoring reported by a partner.
- Weight, alcohol and any medicine changes.
When to reassess
If symptoms last several weeks or worsen, see a doctor. After results, ask what the cause appears to be and when to retest.
When to seek professional support
- A primary care doctor can start the evaluation and refer to a hormone or urology specialist if needed.
- Ask about sleep apnea, mood and fertility assessments if relevant.
What helps
Ordered by how well the research supports each step. Evidence strength is shown on every card; precautions sit next to the advice.
Start here
Describe the whole pattern to a doctor, with the sexual symptoms in particular
Moderate certaintyAddresses: Helps the doctor judge whether a blood test is worth doing
Why it may help: In the European survey of 3,369 men, the three sexual symptoms (poor morning erections, low desire, erectile dysfunction) were the ones with a clear link to low testosterone. Both NHS Highland guidance and MedlinePlus list those symptoms among the main signs, while tiredness and low mood have many other causes.
How to apply it: Note when each change began, how often it happens, and anything that changed around the same time, such as a new medicine, weight change, stress, alcohol, poor sleep or an illness. Bring the list to the visit.
Who it may suit: Men with a lasting change in desire, erections, energy or muscle that has not settled in a few weeks.
Precautions: A symptom list does not diagnose anything. Many men with these symptoms have normal testosterone, and a clinician must interpret the pattern.
6,5,4Understand Hormone Tests → Men's Wellness: A Starting Guide →
Have the blood test done in the morning and repeated if it is low
Moderate certaintyAddresses: Gives a result that can be interpreted reliably
Why it may help: MedlinePlus says the sample is usually drawn in the morning, between 7 and 10 a.m., when testosterone is typically highest, and that fasting is needed only in certain cases. The Endocrine Society recommends fasting morning total testosterone as the first test, confirmed by repeating it, with free testosterone considered when the total is near the lower limit of normal or when something alters sex hormone-binding globulin.
How to apply it: Ask the doctor or laboratory how to prepare. Tell them every medicine and supplement you take. Do not stop any medicine unless the prescriber says so.
Who it may suit: Men whose symptoms and doctor's assessment suggest a test is worthwhile.
Precautions: Results depend on the type of test, your age, symptoms and other conditions, and reference ranges differ between laboratories.
4,1Ask for the common look-alikes to be checked at the same visit
Moderate certaintyAddresses: Avoids treating a hormone number when something else is driving the symptoms
Why it may help: Sleep apnea, obesity, some medicines, alcohol misuse, depression and chronic illness can all lower testosterone or produce the same symptoms. In a meta-analysis, testosterone was lower in men with obstructive sleep apnea than in controls. The AUA notes that chronic fatigue, chronic stress and depression can look like testosterone deficiency.
How to apply it: Mention loud snoring or gasping at night, weight change, low mood, heavy drinking, long-term pain medicine, and symptoms of thyroid or blood-sugar problems, and ask what else should be checked.
Who it may suit: Almost everyone being evaluated.
Precautions: Do not self-diagnose sleep apnea or depression. A clinician should assess both.
7,2,5,4Say plainly if you hope to have a child
High certaintyAddresses: Prevents a treatment choice that could reduce fertility
Why it may help: The Endocrine Society recommends against starting testosterone therapy in men who are planning fertility in the near term. Fertility has its own evaluation.
How to apply it: Tell the doctor before any treatment is discussed, and ask for fertility to be assessed separately.
Who it may suit: Men who are trying for, or planning, a pregnancy with a partner.
Precautions: Male infertility needs a medical evaluation of its own.
1Additional options
Weight loss, if extra weight is part of the picture
Low certaintyAddresses: Associated with a rise in testosterone levels
Why it may help: A meta-analysis of 24 studies found that both a low-calorie diet and bariatric surgery were associated with a significant increase in testosterone, with larger rises in men who lost more weight. Many of the included studies were not controlled trials, and the review looked at hormone levels rather than symptoms.
How to apply it: Gradual, sustainable changes agreed with a clinician. Weight loss is useful for general health whether or not testosterone is low.
Who it may suit: Men with overweight or obesity whose testosterone is low or borderline.
Precautions: Avoid crash diets. People with diabetes or on medicines, and anyone with a history of disordered eating, should get clinician guidance first.
8Lose Weight Sustainably → Obesity and weight-related health →
Ask your prescriber or pharmacist to review medicines that may affect hormones
Low certaintyAddresses: May remove a treatable cause
Why it may help: NHS Highland guidance lists opiate medicines among the causes to consider, and MedlinePlus advises telling the provider about everything you take because some medicines may need to be paused for the test.
How to apply it: Bring a full list, including supplements and anything bought online. Let the prescriber decide about any change.
Who it may suit: Men taking regular pain medicines or other long-term medicines.
Precautions: Never stop a prescribed medicine on your own.
5,4Look after sleep, mood and general health while you wait for answers
Not enough evidenceAddresses: Supports overall wellbeing whatever the result
Why it may help: Sleep problems, low mood and chronic stress can produce the same symptoms. We did not find a trial showing that these steps raise testosterone in men with confirmed deficiency, so they are suggested for general health, not as a fix for a low level.
How to apply it: See the linked pages on sleep, mood and everyday health habits for men.
Who it may suit: All men.
Precautions: If symptoms persist, keep the medical visit; do not use these steps as a reason to delay it.
2Improve Your Sleep Quality → Support a More Balanced Mood → Build Better Everyday Health Habits →
Food & nutrition
Eating, weight and testosterone
We did not find, in the sources read for this page, a food or eating pattern shown to correct a confirmed low testosterone level. Specific foods are therefore not suggested here.
What the sources do support is that weight loss in men with excess weight was associated with higher testosterone in a meta-analysis of 24 studies. A balanced, sustainable eating pattern is a sensible part of overall health, and the linked pages cover it. Avoid crash diets, and seek support if eating feels out of control or fearful.
8Alcohol
MedlinePlus lists alcohol use disorder among the causes of low testosterone levels, so honest information about drinking helps the doctor interpret results.
4Remedies & supplements
Traditional use, laboratory findings and human trials are kept apart. "Natural" does not mean safe.
Anabolic steroids and SARMs (not suggested)
Evidence againstStudied form and route: Injected, oral or marketed as supplements
Intended outcome: None advised
Human evidence: The FDA says SARMs mimic the effects of testosterone and anabolic steroids, are unapproved drugs even when sold as supplements or "for research use only", and cannot be legally marketed in the US as a supplement or drug. It lists heart attack or stroke, liver damage including acute liver failure, infertility, testicular shrinkage, sexual dysfunction, psychosis and sleep disturbances among the risks.
Limits: Adverse events are likely under-reported, according to the FDA.
Interactions and precautions: Avoid. If you have used them, tell your doctor, because they can distort hormone test results.
10Testosterone products used without supervision (not suggested)
Evidence againstStudied form and route: Prescription gel, patch, buccal system or injection obtained outside a proper evaluation
Intended outcome: None advised
Human evidence: The FDA says testosterone products are approved for men who lack or have low testosterone with an associated medical condition, such as testicular failure or hypothalamus or pituitary problems. The Endocrine Society recommends against starting therapy in men who are planning fertility, or who have breast or prostate cancer, elevated PSA or hematocrit, untreated severe sleep apnea or other listed conditions.
Limits: Supervised treatment after confirmed deficiency is a clinician decision; see the Therapies tab.
Interactions and precautions: Treatment needs monitoring of symptoms, blood testosterone, hematocrit and prostate risk. We give no doses.
11,1Over-the-counter "testosterone booster" supplements
Not enough evidenceStudied form and route: Capsules, powders and teas, often herbal blends
Intended outcome: Claimed to raise testosterone
Human evidence: We did not find, among the sources read for this page, human trial evidence that a booster corrects a confirmed low level. The ingredient and claim-check pages on this site rate individual herbs and minerals separately.
Traditional use: Several herbs sold as boosters have traditional use as tonics.
Limits: Product strength and quality vary.
Interactions and precautions: Interactions and liver or hormone-sensitive cautions can apply; ask a pharmacist, and do not use a product in place of evaluation.

Therapies & care
Established care for suspected low testosterone is a medical evaluation: a symptom review, repeated morning blood tests, a search for the cause, and a shared decision about treatment. This page does not recommend any medicine or dose, and you should not start, stop or change a prescribed medicine on your own.
Medical evaluation and repeat testing
Moderate certaintyClinical assessment A clinician reviews symptoms and signs, measures fasting morning total testosterone, repeats it to confirm, may check free testosterone, and looks for the cause with further tests. The Endocrine Society and AUA guidelines both require symptoms and consistently low levels together.
Who it may suit: Men with lasting symptoms that fit the pattern.
Precautions: Results depend on test type, timing and laboratory ranges. Tell the doctor about all medicines and supplements.
1,3,4Treating the underlying cause
Low certaintyClinical care Where a cause is found, such as sleep apnea, obesity, a medicine effect, alcohol misuse or pituitary or testicular disease, care is directed at it. Weight loss was associated with higher testosterone in a meta-analysis.
Who it may suit: Men in whom evaluation finds a modifiable cause.
Precautions: A pituitary or testicular cause needs specialist care.
1,7,8,5Testosterone therapy decided by a clinician
Moderate certaintyPrescription hormone therapy (class only) A clinician may offer therapy when deficiency is confirmed and symptoms are bothersome. In a one-year trial of 790 men aged 65 and over with low levels and symptoms, gel improved sexual activity, desire and erectile function, with no benefit for vitality or walking distance in the main analysis and slightly better mood. In the TRAVERSE trial of 5,246 men aged 45 to 80 with low levels, symptoms and existing or high risk of heart disease, serious heart events were 7.0% with testosterone and 7.3% with placebo, but atrial fibrillation, acute kidney injury and pulmonary embolism were more frequent with testosterone. In 2025 the FDA required a blood pressure warning across the class; in June 2026 it requested label changes that remove a limitation of use for age-related hypogonadism.
Who it may suit: Men with confirmed deficiency and symptoms, after discussing benefits and risks.
Precautions: Not suitable for everyone: fertility plans, prostate or breast cancer, raised PSA or hematocrit and untreated severe sleep apnea are listed by the Endocrine Society. Monitoring is needed.
9,12,1,13,11Mental-health support
Moderate certaintyPsychological care If low mood, anxiety or hopelessness is part of the picture, it deserves care of its own whatever the hormone result.
Who it may suit: Men with persistent low mood, anxiety or thoughts of self-harm.
Precautions: In the US, the 988 Suicide & Crisis Lifeline offers free, confidential support by call, text or chat at any time.
14,15What to avoid
Habits, products and claims that can get in the way. Never stop a prescribed medicine without talking to the professional who prescribed it.
Risks that apply to most people
Treating yourself on the basis of symptoms alone
High certaintyWhy: Symptoms are nonspecific, and the guidelines require low levels on blood tests as well. Using testosterone or booster products without a confirmed deficiency risks side effects and can hide another condition.
Who it applies to: Any man with tiredness, low desire or low mood.
Try instead: Get evaluated first; treatment, if any, is a clinician's decision.
1,2Judging by a single test result
High certaintyWhy: The Endocrine Society recommends confirming the diagnosis by repeating the morning measurement, and MedlinePlus says a test alone cannot diagnose a condition. A one-off low or normal value can mislead.
Who it applies to: Anyone given a result from a clinic, a home kit or an online service.
Try instead: Ask for the result to be repeated and interpreted by a clinician alongside your symptoms.
1,4Ignoring low mood because "it is just hormones"
Moderate certaintyWhy: Depression is a common cause of the same symptoms and has its own care. NHS guidance advises seeing a doctor and not delaying if you think you may be depressed.
Who it applies to: Men with a flat or hopeless mood, loss of interest or irritability.
Try instead: Raise mood openly with the doctor at the same visit.
14Personal triggers to check
Untreated sleep apnea
Moderate certaintyWhy: A meta-analysis found lower testosterone in men with obstructive sleep apnea, and the Endocrine Society recommends against starting testosterone therapy in men with untreated severe obstructive sleep apnea.
Who it applies to: Men who snore loudly, gasp or stop breathing in sleep, or are very sleepy in the day.
Try instead: Ask for sleep apnea to be assessed.
7,1Heavy alcohol use
Moderate certaintyWhy: MedlinePlus lists alcohol use disorder among the causes of low testosterone levels in men.
Who it applies to: Men who drink heavily or regularly.
Try instead: Be open with the doctor about drinking; support is available.
4Long-term opiate pain medicines, without a review
Low certaintyWhy: NHS Highland guidance names opiate medicines among the causes of low testosterone.
Who it applies to: Men on regular strong pain medicine.
Try instead: Ask the prescriber to review it. Do not stop it on your own.
5Products that need caution
Anabolic steroids and SARMs
Evidence againstWhy: The FDA calls SARMs unapproved drugs that cannot be legally marketed as supplements and lists risks including heart attack or stroke, liver damage, infertility, testicular shrinkage, sexual dysfunction and psychosis. They are not a way to treat suspected low testosterone.
Who it applies to: Men tempted by online or gym-sourced products.
Try instead: See a doctor. We give no instructions for these products.
10Testosterone obtained without a confirmed diagnosis
Evidence againstWhy: The FDA says approved testosterone products are for men who lack or have low testosterone together with an associated medical condition. The AUA notes that prescriptions have risen markedly and that guidance was needed on proper assessment.
Who it applies to: Men considering online or clinic offers that skip testing.
Try instead: Insist on symptom review and repeated morning blood tests before any treatment decision.
11,3Over-the-counter "testosterone booster" supplements
Not enough evidenceWhy: We did not find, among the sources read for this page, evidence that these products correct a confirmed low level. None of the FDA-approved testosterone forms is a supplement. They are covered in the dedicated claim check.
Who it applies to: Anyone buying a booster instead of seeking evaluation.
Try instead: Get evaluated first; ask a pharmacist about interactions before any supplement.
11Unsupported claims
"Low energy and low drive in men always mean low testosterone"
High certaintyWhy: In the European survey, tiredness and low mood were related to testosterone but only the sexual symptoms formed a clear pattern with low levels. The AUA lists chronic fatigue, stress and depression as look-alikes.
Who it applies to: Online symptom checklists and advertising.
Try instead: Treat the symptoms as a reason to look for causes, not as a diagnosis.
6,2"Every man over 40 should have his testosterone tested"
Moderate certaintyWhy: The Endocrine Society recommends against routine screening of men in the general population who have no symptoms.
Who it applies to: Wellness-clinic marketing.
Try instead: Test when symptoms and a clinician's judgement call for it.
1"A natural testosterone cure exists"
Evidence againstWhy: We did not find a source showing that any food, herb or supplement cures confirmed low testosterone. The only lifestyle measure with meta-analysis support in the sources we read is weight loss in men with obesity, and it raises levels rather than curing a cause such as pituitary disease.
Who it applies to: Product pages and social media.
Try instead: Find the cause with a doctor.
8Common mistakes
Delaying care for the warning signs
High certaintyWhy: Sudden severe testicle pain can be torsion, an emergency where surgery works best within 4 hours of symptoms starting, according to MedlinePlus. A sudden inability to pass urine also needs urgent care.
Who it applies to: Any man with these signs.
Try instead: Go to emergency care. Do not wait for an appointment.
16,17Stopping a prescribed medicine to see if hormones improve
High certaintyWhy: MedlinePlus says not to stop any medicine unless the provider says so. Stopping some medicines can be harmful.
Who it applies to: Men on long-term prescriptions.
Try instead: Discuss any suspected effect with the prescriber.
4Evidence & safety
What the research shows
Guidelines from the Endocrine Society and the American Urological Association agree that low testosterone is diagnosed only when suggestive symptoms and consistently low morning blood levels are both present, and the Endocrine Society recommends against screening men who have no symptoms. Sexual symptoms are the most specific; fatigue and low mood overlap with many other conditions. Randomized trials show benefit of treatment mainly for sexual function and no cardiovascular excess in one large trial, with some other risks.
Limits of the evidence
- Cut-offs for a low level differ between laboratories and guidelines.
- The European survey was observational and its thresholds are research criteria.
- Meta-analyses on sleep apnea and weight loss combine studies of mixed design and show associations.
- Treatment trials were run in men with low levels and symptoms and may not apply to everyone.
- We could not read the full text of the AUA guideline, which is behind a login, so only its public summary is used.
Precautions and interactions
- Never start, stop or change testosterone, thyroid, diabetes or other prescribed medicines without the prescriber.
- Unsupervised testosterone, anabolic steroids, SARMs and boosters can harm fertility, the heart, liver and mood.
- Tell the doctor about all supplements before any test.
Life-stage considerations
- Teenagers and boys: puberty questions need a clinician; see the puberty page.
- Men planning a child: treatment can affect fertility; ask for a fertility assessment.
- Older men: testosterone decreases with age; symptom review matters more than the number alone.
- Couples planning a pregnancy: male fertility is assessed separately from testosterone, so mention plans to the doctor.
Warning signs
- Sudden severe testicular pain or pain after an injury.
- Sudden inability to pass urine.
- Chest pain, fainting or new breathlessness.
- Low mood that persists, hopelessness or any thought of self-harm: contact a doctor or crisis line now.
Claim checks
Symptoms prove you have low testosterone
High certaintySymptoms are nonspecific, and a diagnosis needs consistently low blood levels too.
1,2One blood test settles it
High certaintyThe Endocrine Society recommends repeating the morning measurement.
1,4Testosterone therapy raises vitality and energy
Moderate certaintyIn a one-year trial in older men with low levels, gel did not improve vitality in the main analysis, while sexual function improved.
9Testosterone therapy is proven to be heart-safe for everyone
Moderate certaintyOne large trial found similar major heart events versus placebo in a high-risk group, but more atrial fibrillation, kidney injury and pulmonary embolism; the FDA requires a blood pressure warning.
12,13Boosters and SARMs are a safe shortcut
Evidence againstThe FDA warns against SARMs and lists serious risks; boosters lack supporting evidence in the sources we read.
10,11Questions people ask
What are the signs that could point to low testosterone?
MedlinePlus lists low sex drive, erectile problems, infertility, enlarged breasts, reduced facial or body hair, thinning bones or unexplained anemia, and muscle loss. Fewer morning erections are also named by NHS Highland guidance. Many of these have other causes.
Are tiredness and low mood signs of low testosterone?
They can be related, but they are nonspecific. The AUA notes that chronic fatigue, stress and depression can look the same. In a European survey, only the sexual symptoms formed a clear pattern with low levels.
When should I get tested?
When lasting symptoms fit the pattern and a doctor judges testing worthwhile. The Endocrine Society recommends against screening men who have no symptoms.
What time of day is the test done?
MedlinePlus says the sample is usually taken in the morning, between 7 and 10 a.m., when levels are typically highest. Ask whether you need to fast.
Does a low result mean I need treatment?
Not necessarily. MedlinePlus says an abnormal result does not always mean a condition that needs treatment. The Endocrine Society recommends repeating the test and looking for the cause.
Is it normal for testosterone to fall with age?
Yes, MedlinePlus says it is normal for levels to decrease with age. What matters is your symptoms and repeated results, interpreted by a clinician.
Can sleep apnea or weight affect testosterone?
A meta-analysis found lower testosterone in men with obstructive sleep apnea, and another found weight loss was associated with higher testosterone. Both are associations, so ask a doctor to assess them.
Can I use a booster instead of seeing a doctor?
We did not find evidence that boosters correct a confirmed low level, and symptoms may have another cause. See the claim-check page, and get evaluated first.
Does testosterone therapy affect fertility?
The Endocrine Society recommends against starting therapy in men planning fertility in the near term. Tell the doctor if you hope to have a child.
What if I feel hopeless or have thoughts of harming myself?
Contact a doctor or emergency services now. In the US, the 988 Suicide & Crisis Lifeline offers free, confidential support by call, text or chat at any time.
Where do I read about erection problems?
Sexual health is covered separately. See the erectile dysfunction page, and mention it to your doctor.
