Management for eugonadism with testosterone 282 ng/dL?

Management of Testosterone Level of 282 ng/dL in a 35-Year-Old Male

Testosterone replacement therapy is recommended for this 35-year-old male with a testosterone level of 282 ng/dL, as this value falls below the diagnostic threshold of 300 ng/dL for testosterone deficiency. 1

Diagnosis Confirmation

• A testosterone level of 282 ng/dL is below the American Urological Association's threshold of 300 ng/dL used to categorize a man as hypogonadal 1
• Diagnosis should be confirmed with a second morning total testosterone measurement before initiating treatment 1
• For men in the 30-34 age group, age-specific cutoffs suggest values below 359 ng/dL may be considered low, further supporting the diagnosis in this 35-year-old patient 2
• Clinical diagnosis requires both low testosterone levels AND symptoms/signs of testosterone deficiency 1

Evaluation Before Treatment

• Measure serum luteinizing hormone (LH) levels to help establish the etiology of testosterone deficiency (primary vs. secondary hypogonadism) 1
• Assess for symptoms associated with low testosterone, including:
  • Reduced energy and endurance 1
  • Diminished sexual function and libido 1, 3
  • Changes in mood, concentration, and memory 1
  • Decreased muscle mass and strength 1
• Screen for contraindications to testosterone therapy:
  • Breast or prostate cancer 4
  • Elevated PSA (>4 ng/ml or >3 ng/ml in high-risk men) 4
  • Hematocrit >50% 4
  • Severe untreated obstructive sleep apnea 4
  • Severe lower urinary tract symptoms 4
  • Uncontrolled heart failure 4
  • Recent cardiovascular events (within past 3-6 months) 1

Treatment Recommendations

• Initiate testosterone replacement therapy with the goal of achieving testosterone levels in the middle tertile of the normal reference range (450-600 ng/dL) 1
• Choose formulation based on patient preference, pharmacokinetics, and cost 4:
  • Transdermal gel provides continuous delivery for 24 hours with once-daily application 5
  • Intramuscular injections are an alternative option 1
• Avoid alkylated oral testosterone due to risk of liver toxicity 1
• Do not prescribe testosterone if the patient is currently trying to conceive, as it can suppress spermatogenesis 1

Lifestyle Modifications

• Counsel regarding lifestyle modifications as an adjunct to testosterone therapy 1:
  • Weight loss if overweight or obese 1
  • Increased physical activity 1
  • These measures may help increase endogenous testosterone levels and reduce symptoms 1

Monitoring

• Follow up to assess symptom improvement:
  • Sexual function (libido, erectile function) 3
  • Energy levels and mood 3
  • Physical changes in muscle mass and strength 1
• Monitor testosterone levels to ensure they reach the target range of 450-600 ng/dL 1
• Monitor for potential adverse effects:
  • Hematocrit elevation (polycythemia) 1
  • Cardiovascular symptoms 1
  • Prostate-related issues 4
• If symptoms don't improve despite reaching target testosterone levels, consider discontinuing therapy 1

Special Considerations

• Recent research suggests men with untreated hypogonadism may have increased risk of COVID-19 hospitalization compared to eugonadal men or those receiving adequate testosterone therapy 6
• Testosterone therapy may improve metabolic parameters including insulin sensitivity, glucose control, and body composition in men with hypogonadism 1
• Patients should be advised that current evidence does not definitively demonstrate increased cardiovascular risk with testosterone therapy 1
