Your T/E2 ratio is 22.00, within the typical research-reported range of 10-30.

  • Your testosterone (550.0 ng/dL) is within the typical male reference range of 300-1000 ng/dL.
  • Your estradiol (25.0 pg/mL) is within the typical male reference range of 14-55 pg/mL.
  • Both hormones play essential roles: testosterone supports muscle mass, libido and bone density, while estradiol protects cardiovascular and bone health.

Next stepEven within the reference range, symptoms and clinical context matter. Follow up with your doctor if you experience symptoms like low libido, fatigue or mood changes.
