The U.S. military has announced plans to screen service members for low testosterone, a move that has prompted concern from medical experts about potential overdiagnosis and unnecessary treatment.
The screening initiative reflects growing awareness of testosterone's role in physical performance, mood, and bone health. Military leadership views the program as a way to identify and support soldiers who experience symptoms like fatigue, reduced muscle mass, or depression that could affect readiness and wellbeing.
However, endocrinologists and primary care physicians worry the broad screening approach may pathologize normal variations in testosterone levels. Testosterone naturally declines with age and fluctuates based on stress, sleep, body composition, and acute illness. A single low reading does not confirm clinical hypogonadism, which requires symptoms plus confirmed low levels on repeat testing.
Dr. Ravi Dhir, a urologist, and other specialists caution that mass screening without careful symptom assessment can lead to unnecessary testosterone replacement therapy. Such treatment carries real risks: it can suppress natural testosterone production, raise red blood cell counts to dangerous levels, increase cardiovascular strain, and potentially affect fertility. Long-term safety data in younger, healthier populations remains limited.
The concern centers on diagnostic creep. When screening programs cast wide nets, normal-range results get reinterpreted downward, expanding the population deemed "deficient." Military pressure to maintain peak performance could incentivize soldiers to seek treatment even when benefits are unclear.
Medical societies including the American Academy of Family Physicians emphasize that testosterone screening should target symptomatic men with specific complaints, not entire populations. A thoughtful approach involves careful history-taking, measurement of both total and free testosterone, and consideration of underlying causes like sleep apnea, obesity, or medication effects before initiating hormone therapy.
The military's intention to support soldier health is sound. Implementation matters enormously. Screening without restrictive diagnostic criteria and
