Defense Secretary Pete Hegseth wants the military to begin annual screening for testosterone deficiency, a move that would make the tests mandatory for service members 30 and over and available to volunteers under 30. Those who do not meet the cut would be able to choose testosterone replacement therapy.
The push lands because it turns a hormone into a readiness question. Hegseth has said the force should be kept on the leading edge of lethality, and Lori Falce wrote that he is concerned about your testosterone. The idea is not a vague wellness check. It would put hormone testing into routine military medical screening for a broad slice of the force, with age determining whether the exam is required or optional.
That matters because the military is not dealing only with low testosterone. The reporting says low levels can show up as muscle loss, fatigue, depression and low sex drive. It also says higher testosterone carries medical risks, including prostate cancer, high blood pressure, mood swings, irritability and a greater risk of heart attack. In other words, the same measure Hegseth wants to use as a marker of strength can also point to problems on either side of the line.
The numbers help explain why the issue has become so visible. A National Institutes of Health study found a 400% increase in testosterone replacement therapy among men ages 18 to 45 between 2003 and 2013. The reporting also cites Harvard University as saying high testosterone in men is not common. That leaves Hegseth making a case for testing in a field where both deficiency and excess can raise concerns, but where the balance of risk is far from simple.
There is also a larger argument under the policy. The screening push sits inside a broader fight over military standards and gender politics, and the Trump administration has adamantly opposed gender-affirming care. Hegseth’s record, as described in the reporting, includes firing high-ranking women or passing them over for recommended promotions. Against that backdrop, a testosterone policy reads less like a narrow medical proposal than part of a wider effort to redefine what the force should look like.
What remains unanswered is whether the plan has been formally adopted or when it would start. For now, the proposal is clear enough to know who it would touch and what it would test for. The harder question is whether the military is about to make hormone screening a standing part of readiness, or whether this is another Hegseth idea that stops at the edge of announcement.
