Relative Androgen Deficiency in Men: What It Means and How It’s Evaluated
Medically reviewed by Dr. Timothy Mackey

The short answer
“Relative androgen deficiency” is a descriptive term used in some discussions of testosterone and symptoms. It should not be treated as proof that someone needs TRT because their level is below a personal or age-based “optimal” target. Evaluation should follow established diagnostic criteria and consider other explanations for symptoms.
A total testosterone result in the 300s ng/dL does not by itself establish deficiency or predict a large benefit from treatment. Persistent symptoms warrant assessment, including repeat morning testing and, when appropriate, reliable free-testosterone evaluation. Decisions should reflect the complete clinical picture rather than age alone.
What is Relative Androgen Deficiency?
Symptoms such as low libido, fatigue and changes in body composition can occur for reasons other than testosterone deficiency. A value near the lower end of a laboratory range deserves interpretation alongside symptoms, medical history, medications and the timing and method of testing. It is not an automatic indication for treatment.
Age and testosterone: Changes vary between individuals and are influenced by health conditions, medications and other factors. A fixed annual decline is not a personal forecast, and age alone does not diagnose testosterone deficiency or justify treatment. Care should address identified problems rather than promise to reverse aging. Our Normal Testosterone Levels by Age reference explains age-related results and their limits.
Testosterone levels: Laboratory reference intervals, diagnostic thresholds and treatment targets are different concepts. “Relative androgen deficiency” and “subclinical hypogonadism” should not be used as interchangeable diagnoses. See our comparison of relative androgen deficiency and subclinical/compensated hypogonadism for the distinction. The AUA guideline uses total testosterone below 300 ng/dL as a reasonable supporting threshold, together with repeat testing and symptoms or signs.
Symptoms of Androgen Deficiency: Some of the symptoms associated with relative androgen deficiency (often called Low T), may include:
- Decreased Sex Drive (Low libido)
- Erectile dysfunction (ED)
- Fatigue and decreased energy levels
- Loss of lean muscle mass and overall strength
- Increased body fat, particularly around the abdomen
- Decreased bone mineral density (osteoporosis)
- Decline in cognition/brain fog
- Mood changes, like depression and/or irritability
Evaluation: The purpose is to identify the cause of symptoms and whether treatment is appropriate. A consultation and blood testing do not guarantee a testosterone prescription.
Clinical assessment of symptoms via physician consultation.
Testosterone testing generally starts with total testosterone measured on two separate mornings. The Endocrine Society recommends fasting morning testing. Reliable free-testosterone assessment can help when total testosterone is borderline or SHBG is altered. Free testosterone is the unbound fraction; it is not identical to bioavailable testosterone, which also includes albumin-bound testosterone. Additional tests depend on the clinical findings.
Consideration of other factors that could influence testosterone levels, such as overall health, medications, lifestyle choices and comorbid conditions.
Treatment of Low Testosterone: The management of relative androgen deficiency may include:
Lifestyle changes, such as improving diet, avoiding drugs and alcohol, increasing physical activity and exercise specifically weight training, reducing stress, and increasing sleep.
Addressing any underlying health or medical conditions that may help contribute to low testosterone levels.
Testosterone replacement therapy (TRT) might be considered for those men who have consistently low testosterone levels along with significant symptoms that impacts their quality of life. TRT should be carefully monitored by an experienced healthcare provider due to potential risks and side effects.
Treatment decisions: Discuss likely benefits, limitations, fertility goals and individual risks. The clinician should reassess symptoms and safety during follow-up. Aiming for a personal “optimal” number is not a substitute for a supported diagnosis.
Symptoms deserve assessment even when an initial result falls within the laboratory range, but treatment benefit should not be promised on that basis. A clinician can review repeat testing, possible causes and the risks and benefits of appropriate options.
