Key Points
-
Testosterone influences mood, energy, sexual health, and other body systems in men and women—but symptoms alone don’t confirm low testosterone. Testing and clinical evaluation are needed.
-
TRT is prescribed for diagnosed hypogonadism, not for age-related low testosterone alone, and requires individualized risk–benefit discussion and monitoring.
-
If you’re experiencing persistent fatigue, mood changes, sexual concerns, or other symptoms, talk with a clinician about evaluation and appropriate testing rather than self-diagnosing.
Feeling Off? It Might Be Time to Talk Hormones
If you’ve been dealing with low energy, irritability, changes in sexual function, or just not feeling like yourself, hormones could be part of the picture. Testosterone is one of several factors that can affect how you feel day to day; understanding when testing makes sense helps you get answers without guesswork.
Understanding Testosterone
Testosterone is a naturally occurring hormone that helps regulate sexual function, mood, energy, red blood cell production, and bone health. Women also produce testosterone in smaller amounts. Levels change with age and health conditions, and interpretation should be done by a clinician who can consider both symptoms and labs.
Possible Signs of Low Testosterone
Symptoms can overlap with other conditions (sleep issues, depression, thyroid disorders, medication effects), so they’re not diagnostic on their own. People with low testosterone may report:
-
Persistent fatigue or reduced stamina
-
Depressed mood, low motivation, or irritability
-
Changes in sexual function or desire
-
Decreased bone density noted on imaging; reduced shaving frequency (in men)
-
Difficulty concentrating or feeling “foggy”
If these concerns are ongoing, a focused evaluation can determine whether testing is appropriate.
Common Causes and Risk Factors
Medical causes can include primary testicular disorders or pituitary disease; other contributors include certain medications, chronic illnesses, sleep apnea, and obesity. A clinician can assess for reversible causes before discussing treatment.
Diagnosis and Testing: What to Expect
Testing typically involves early-morning blood draws on two separate days and a clinical assessment of symptoms. Diagnosis is not based on a single number; reference ranges vary by lab, and clinicians combine symptoms with repeated low morning levels to confirm hypogonadism. The American Urological Association notes that a total testosterone below 300 ng/dL can be a reasonable cut-off in context.
Your provider may also check related labs (e.g., LH/FSH, prolactin) and discuss prostate screening where appropriate, along with baseline hematocrit and follow-up plans if treatment is considered.
Treatment and Management
For people diagnosed with hypogonadism, options may include testosterone replacement therapy (TRT) in addition to addressing underlying causes and lifestyle factors. Decisions are individualized—your clinician will review goals, potential risks, and a monitoring schedule.
Important labeling notes:
-
The FDA has updated testosterone product labels to reflect clinical trial data showing no increase in major adverse cardiovascular events in men treated for hypogonadism, while also adding a warning about increased blood pressure in some formulations. Labels continue to limit use to men with medical causes of low testosterone (not age-related decline).
Monitoring typically includes periodic labs (e.g., hematocrit/hemoglobin, testosterone levels) and clinical follow-up; your provider will tailor frequency to your plan and health status.
Bottom line: Treatment—when appropriate—focuses on normalizing levels and reducing symptoms under supervision, not on performance enhancement or aesthetic goals.
When to Consider Getting Tested
Consider speaking with a clinician about testing if you have several of the symptoms above for at least a few months, especially with relevant risk factors (sleep apnea, certain medications, chronic conditions) or physical findings your provider identifies. A visit can help determine whether testing is warranted and what other conditions should be ruled out.
