Overview
- Defense Secretary Pete Hegseth directed the military to add annual testosterone tests to periodic health assessments for service members age 30 and older and to make testing optional for younger troops, a policy announced on Monday that has not yet been implemented with formal protocols.
- Officials have not published how low results will be confirmed or monitored over time so clinicians and researchers warn a single blood draw can be misleading because clinical guidelines call for two separate morning tests plus persistent symptoms to diagnose hypogonadism.
- Experts say intense training, sleep loss, illness and stress can temporarily cut testosterone levels, so tests taken during or right after strenuous military activities could produce false positives and prompt unneeded therapy.
- Testosterone replacement therapy can help people with true, confirmed deficiency but it also suppresses sperm production and can cause higher red blood cell counts, blood clots, atrial fibrillation, kidney injury and other harms, so fertility counseling and long-term monitoring are critical for younger service members.
- The order has drawn political scrutiny and practical questions about cost, inclusion of women, deployment access to treatment, and evidence that routine screening will improve readiness against a backdrop of rapidly rising civilian TRT use and an FDA decision to ease a prior cardiovascular warning after the TRAVERSE trial.
