Counseling Patients with Normal Testosterone Levels Against Testosterone Therapy

Introduction to Testosterone Therapy

The American Urological Association recommends that testosterone therapy should not be prescribed to patients with normal testosterone levels because treatment is only indicated when both biochemical deficiency and clinical symptoms of hypogonadism are present, as giving testosterone to men with normal levels provides no benefit and exposes them to significant risks 1
Testosterone therapy aims to bring levels to 450-600 ng/dL, and if a patient's levels are already in this range or higher, therapy cannot improve upon normal physiology and the risk-benefit ratio becomes entirely unfavorable 1

The American Urological Association guideline explicitly states that the goal of therapy is "normalization of total testosterone levels combined with improvement in symptoms"—if levels are already normal, there is nothing to normalize 1
Biochemical requirement for testosterone therapy is two separate morning testosterone measurements showing levels below 300-350 ng/dL 2

Exogenous testosterone completely shuts down sperm production through negative feedback on the hypothalamic-pituitary-gonadal axis, and the AUA provides a strong recommendation that "exogenous testosterone therapy should not be prescribed to men who are currently trying to conceive" because it causes severe oligospermia or azoospermia 1
Patients must wait 3-6 months after any cardiovascular event before even considering therapy, and men on therapy must report chest pain, shortness of breath, or dizziness immediately 1
The current literature cannot definitively prove safety regarding major adverse cardiovascular events (MACE) 1, 2
Testosterone increases hemoglobin/hematocrit, with therapy withheld if hematocrit exceeds 50%, and polycythemia risk requires regular monitoring and potential phlebotomy 2, 3
Men over 40 require PSA monitoring with specific thresholds for biopsy: increases >1.0 ng/mL in the first year or >0.4 ng/mL per year thereafter mandate urologic evaluation 2, 3

Lifestyle modifications, such as weight loss and increased physical activity, are the primary recommendation and can increase testosterone levels in men who actually have deficiency 1
High body mass index coupled with normal testosterone still warrants weight loss counseling for cardiovascular risk reduction, not testosterone therapy 1

The evidence supports treating deficiency to normal, not pushing normal to supraphysiologic, and starting with normal levels guarantees that testosterone therapy will not provide symptomatic relief 1
