A urologist who treats men with low testosterone every day checked his own levels when he suspected he had the condition and found them within the normal range. "Turns out it was more so my sleep and stress and everything else," Dr. Jamin Brahmbhatt of Orlando Health told NPR.
That anecdote sits at the center of a diagnostic problem now reaching millions of American men through social media and online prescribing. The symptoms most commonly attributed to low testosterone are among the least specific in medicine, and treating them as proof of a hormone deficiency skips the step that determines whether hormone therapy is the right answer at all.
The stakes have grown. The military plans to begin screening service members for low testosterone, online clinics have made prescriptions easy to obtain, and prominent public figures, including podcaster Joe Rogan and Health Secretary Robert F. Kennedy Jr., have discussed their own use of testosterone therapy.
The Symptom Overlap That Makes Self-Diagnosis Unreliable
Testosterone deficiency, known clinically as hypogonadism, produces depressed mood, fatigue, reduced libido, weight gain, and trouble concentrating. Brahmbhatt says the challenge is that every one of those can easily be attributed to other causes.
Sleep deprivation alone produces most of that list. So does untreated depression, and so does chronic stress. Obstructive sleep apnea, thyroid disease, anemia, uncontrolled diabetes, and medication side effects all overlap substantially. A man who reads that list online will recognize himself in it, whether his testosterone is low or not.
Brahmbhatt told NPR he sees men who have spent hours in online forums convinced they need testosterone before they have spoken to a doctor or had their levels tested, and said that not every man needs to be on it.
Dr. Helen Bernie, director of Sexual and Reproductive Medicine at Indiana University, points to contributing factors in younger and middle-aged men that go beyond aging, including obesity, diabetes, sleep apnea, drug use, and other medical conditions. That framing changes the clinical question. "It's not just a testosterone issue, but a men's health issue," Bernie said. She also warns against marketing built around the category, saying the goal of therapy is to restore normal physiology in men with a true deficiency, rather than to achieve peak performance.
The Confirmatory Testing a Proper Evaluation Requires
Guidelines from the American Urological Association and the Endocrine Society say testosterone therapy should be recommended only after identifying symptoms and consistently low levels based on two separate blood tests. Timing matters as well, because testosterone follows a daily rhythm and peaks in the morning, which is why draws are conventionally scheduled early in the day.
A single low result is also not stable. Acute illness, poor sleep the night before, recent heavy exercise, and significant stress can all depress a measurement temporarily. That is why it is repeated.
A complete workup does more than confirm the number. It looks for a cause, which can include pituitary disorders, genetic conditions, medication effects, obesity, and sleep apnea, and it establishes a baseline for monitoring if treatment begins. Brahmbhatt has said that step is not always happening, describing clinics where a patient can walk in or go online and get a prescription without full testing or follow-up as "the unsafe territory."
Testosterone is not a benign supplement. It is a controlled substance with real effects on red blood cell production, fertility, and cardiovascular physiology, which is why monitoring matters as much as the initial prescription. Therapy suppresses sperm production and, in some cases, can lead to permanent infertility, a consequence that weighs most heavily on younger men.
The Access Problem Cutting in Two Directions
The rise of direct-to-consumer hormone clinics has created a genuine tension that neither side of the debate resolves cleanly.
On one side, men with real hypogonadism have historically gone undiagnosed, in part because the primary symptoms involve mood and sexual function, subjects many men avoid raising with a physician. Easier access has pulled some of those men into care.
On the other side, the same convenience allows prescriptions to be issued after a brief questionnaire, sometimes without confirmatory testing and often without structured follow-up. A secret shopper study of online testosterone clinics published in JAMA Internal Medicine sent a fictitious patient with normal levels to seven such clinics and found most were prepared to prescribe anyway. Cash-pay models also mean prescriptions frequently sit outside the records a primary care physician can see, complicating monitoring for anyone managing other conditions. The pattern resembles the one MedicalDaily documented in the market for peptides sold without approval or oversight.
The regulatory ground is also shifting. Under current criteria, testosterone therapy is approved only for men whose low levels trace to an identifiable medical condition, and the Food and Drug Administration has signaled it wants to broaden that standard so that men with low testosterone from any cause could qualify if low libido is present. Specialists disagree sharply about whether the evidence supports the change, with some calling it overdue and others arguing that the long-term benefits and harms are not yet well characterized.
For readers, the useful distinction is not between online and in-person. It is whether the evaluation includes repeat confirmatory testing, a search for treatable causes, a discussion of fertility implications, and a defined follow-up schedule.
Questions Worth Bringing to an Appointment
Anyone experiencing persistent fatigue, low mood, reduced libido, or difficulty concentrating should be evaluated rather than self-treating, and the evaluation should start broad. Reasonable questions include whether sleep apnea has been considered, whether thyroid function and blood count have been checked, whether current medications could be contributing, and whether depression screening is appropriate.
Someone already taking testosterone, or considering it, can ask how many measurements were used to establish the diagnosis, what cause was identified, how red blood cell counts will be monitored, and what the plan is regarding fertility.
Sleep and stress deserve direct attention rather than treatment as a footnote. Persistent snoring and daytime sleepiness are reasons to consider a sleep study. Weight, alcohol use, and untreated diabetes all influence hormone levels and are modifiable in ways a prescription is not, though clinicians acknowledge that telling an exhausted, overweight patient to simply exercise more is rarely sufficient on its own.
Nobody should start or stop a prescribed medication based on a news article; this reporting is general information, not a diagnosis. The reasonable next step for a man who recognizes himself in the symptom list is to make an appointment, not to complete a questionnaire. MedicalDaily will continue reporting on regulatory and clinical developments in hormone therapy, including any changes to federal screening plans.
Key Questions Answered
What symptoms are attributed to low testosterone? Depressed mood, fatigue, reduced libido, weight gain and trouble concentrating. Clinicians note these overlap heavily with sleep loss, stress, depression, sleep apnea, thyroid disease and other conditions.
How is low testosterone actually diagnosed? Urology and endocrine guidelines call for symptoms plus consistently low levels on two separate blood tests, evaluated by a clinician who considers other causes. Testosterone peaks in the morning, so draw timing affects the result.
Why do guidelines require two tests? A single reading can be depressed temporarily by illness, poor sleep, heavy exercise or stress. Repeating the measurement reduces the chance of treating a man whose levels are normal.
What is the concern about online clinics? Urologists say some clinics prescribe without complete testing or follow-up. A published secret shopper study found that most clinics tested were willing to prescribe to a patient with normal levels.
Is testosterone therapy risky? It is a controlled substance that affects red blood cell production, fertility, and cardiovascular physiology. It suppresses sperm production, which is why monitoring is part of appropriate care.
Who should consider evaluation? Anyone with persistent fatigue, low mood, reduced libido or concentration problems. The evaluation should look for treatable causes rather than starting with a hormone prescription.
Can lifestyle factors affect testosterone? Clinicians cite obesity, diabetes, sleep apnea, and drug use as contributing factors in younger and middle-aged men, alongside the gradual decline that comes with age.
