Washington is tightening the rules on troop fitness. The US Department of Defense has issued an immediate directive requiring mandatory testosterone screening for all active-duty and reserve service members aged 30 and older. The order, which took effect at once, reflects Defense Secretary Pete Hegseth’s push to raise the physical and combat readiness of the American armed forces.
Under the new policy, male soldiers over 30 will undergo periodic, compulsory blood tests to measure testosterone levels. Younger male troops will only be tested if they request it or show warning symptoms of a hormonal imbalance. Female service members are exempt from routine screening altogether; they will instead be evaluated case by case for chronic fatigue or menstrual irregularities that could point to a hormonal imbalance or low energy levels.
The Pentagon says the goal is to sharpen field readiness, cut down on hormone-related health issues within the ranks, and boost soldiers’ stamina. The directive also lays out standardized treatment pathways for both men and women once a deficiency is confirmed.
Not everyone is convinced. The decision has triggered sharp debate among medical professionals and defense officials, many of whom are questioning its scientific basis and whether such broad screening is truly warranted. In response, the Food and Drug Administration has announced plans to convene a panel of experts to examine the medical uses of testosterone therapy. Several physicians have already warned of the health risks tied to mass screening, cautioning that it could lead to a wave of unnecessary hormone treatments.
The initiative is the latest in a string of reforms rolled out under Hegseth’s watch, each pitched as a step toward a leaner, more combat-ready military. Whether the new protocol delivers on that promise, without opening the door to the very overtreatment doctors fear, remains an open question the Pentagon will have to answer as the policy rolls out across bases nationwide.
