Pentagon puts testosterone tests into every health check for troops aged 30 and up

The Defense Health Agency issued clinical guidance on 2 September that puts testosterone screening into the Periodic Health Assessment for every American active-duty and reserve service member aged 30 or older. The rule is effective immediately. It implements a 15 July memorandum from Defense Secretary Pete Hegseth titled “Health and Human Performance Optimization to Enhance Military Readiness.”

Men 30 and older will take a mandatory blood test. Men under 30 may request the test or be offered it if a clinician sees warning signs. If the result is low, further evaluation follows. Hormone replacement, if prescribed, is voluntary. Pentagon spokesman Sean Parnell said the guidance also covers “female hormonal optimization.” Women will not face routine testosterone blood tests. They will be screened for fatigue and disrupted menstrual cycles linked to low-energy availability and relative energy deficiency in sport. Off-label testosterone for women is limited, in the document, to postmenopausal patients with unusually low sexual desire.

Hegseth announced the programme in a July video posted on the department’s channels under the title “The High T Department of War.” He said ageing often lowers testosterone and that the point was to restore natural capabilities, not to offer artificial enhancement. He framed the work as a response to Operator Syndrome, a cluster of problems first described in special-operations research around 2020.

Physicians outside the Pentagon have been less sure. Reuters reported that some doctors see little evidence that universal screening of a military population will improve combat performance, and they worry that a normal age-related decline will be treated as a deficiency. Testosterone gels and injections carry known risks: fertility effects, thickening of the blood, mood change. A voluntary treatment clause does not, by itself, prevent a culture in which a low number on a lab slip becomes a career signal.

The paperwork trail is explicit. Hegseth’s July memo ordered the Under Secretary for Personnel and Readiness to rewrite DoD Instruction 6200.06, the Periodic Health Assessment rule, by 15 August. The Military Departments and the Defense Health Agency were told to train clinicians and to make testing available across the Military Health System. Wednesday’s DHA memorandum is the clinical how-to that those earlier orders required.

The policy sits beside other Hegseth fitness moves, including a service test that applies a single male standard to combat roles. Together they amount to a bet that hormone numbers and gym numbers can be managed as readiness metrics in the same way hearing and vision already are. Whether the lab programme reduces injuries and separations, or simply adds a new pharmaceutical line to sick call, will take more than one assessment cycle to measure.

For the troops the immediate change is practical. At the next PHA, men over 30 should expect a testosterone draw. Women should expect questions about energy and cycles. Replacement therapy, if offered, can be refused. The guidance does not say what happens to a file if the number is low and the service member declines the prescription. That gap is where command culture will write the real rule.

The department has published the three underlying memos: the July readiness order, a total-force fitness note, and this week’s clinical guidance. Those texts are the source of record. Everything else is interpretation, including the claim that a blood number is now a measure of lethality.
