US military revokes mandatory testosterone testing guidance

The rapid reversal signals internal friction between readiness-driven policy and evidence-based medical standards, a tension likely to recur as the Pentagon revisits the guidance. The withdrawal may reassure service members concerned about privacy or career implications, but the stated intent to 'update' rather than scrap the measure suggests testosterone screening remains on the table. Watch whether the revised document incorporates expert input or simply repackages the original rationale, as that will determine whether this becomes a precedent for other biomarker-based readiness policies.
