Washington, D.C. — Defense Secretary Pete Hegseth announced that the Pentagon will require annual testosterone deficiency screenings for active-duty service members age 30 and older.
The new screening will be added to the military’s existing annual health assessments. Hegseth said service members under 30 may request the test voluntarily, and any treatment recommended after screening, including testosterone replacement therapy, will remain optional.
Hegseth framed the policy as a military readiness and long-term health measure, saying it is intended to help troops maintain physical and mental performance rather than provide artificial enhancement. The Pentagon has not yet released details on when the requirement will take effect across the military branches.
Newsweek reported that testosterone affects muscle mass, bone density, red blood cell production, energy, and sex drive. Medical groups generally recommend treatment only when low testosterone is confirmed through testing and accompanied by symptoms.
Potential risks of testosterone therapy can include acne, fluid retention, reduced fertility, increased red blood cell counts, and worsened untreated sleep apnea, making follow-up monitoring important.
