Pete Hegseth Mandates Testosterone Screening for Military Personnel

Defense Secretary Pete Hegseth Mandates Testosterone Screening for Troops

The Pentagon’s Testosterone Screening Policy

The Department of Defense’s move to implement testosterone testing for troops represents a significant shift in military health protocols. According to reporting by Business Insider, the policy—announced by Defense Secretary Pete Hegseth—specifies that new testosterone screening during annual check-ups will apply automatically to all service members 30 years old and older. Younger service members, who constitute the vast majority of the military—with 2024 Pentagon data indicating nearly half of all troops are 25 years old or younger—can opt into the screening. Anyone identified with low testosterone levels would then be given the option to pursue recommended treatments, such as taking supplemental testosterone.

Stuart Phillips Critiques Diagnostic Reliability for Young Service Members

The announcement, which was accompanied by the caption The High T Department of War, opened the screening to all “warfighters,” regardless of gender. This initiative is part of a broad pattern of testosterone fixation within the current administration, spanning from new language in dietary guidelines to an FDA push to make treatments more accessible. Despite these stated goals, the announcement has met with mixed reactions from the scientific community.

Medical Concerns and Diagnostic Complexity

Health researchers have raised alarms that the broad testing approach may be ill-suited for a military population where the vast majority of personnel are under 30. Stuart Phillips, a kinesiology professor at McMaster University who has published research on testosterone, stated that there is no good evidence the policy would reliably boost performance or longevity in men under 50. It's a little bit odd, he told Business Insider. I'm not exactly sure what the problem is that's being addressed.

A primary concern is the risk of misdiagnosis and over-prescription. According to American Urological Association guidelines, a diagnosis of low testosterone requires multiple tests, along with existing symptoms such as low libido, fatigue, and loss of muscle mass. Experts warn that because hard physical training can cause temporary fluctuations in hormone levels, a single test could result in thousands of healthy soldiers being incorrectly labeled as having low testosterone. When you screen the whole force on a single test, you're going to label probably thousands of perfectly healthy soldiers as low T when levels actually swing hour to hour anyway, Phillips said.

Eric Feigl-Ding Links Hormone Suppression to Military Stress and Sleep Deprivation

In a young man with low testosterone, usually that's a symptom of other things, not the disease itself, Phillips noted. It's a little bit of the cart before the horse scenario. The reality is there are probably lots of other things that are the problem, making the hormone low.

Eric Feigl-Ding, a public health researcher at the New England Complex Systems Institute, echoed these concerns, stating that suddenly giving T to young adults who don't have major symptoms is not necessarily wise. He emphasized that such an approach ignores the root causes of hormone suppression in the military, such as chronic stress, sleep deprivation, and high rates of obesity. These issues are particularly pronounced among the small percentage of troops who serve in special operations, such as Navy SEALs. Furthermore, a 2020 military medical study found that sleep deprivation sharply decreased testosterone levels for Army Rangers in training. Other research has linked low testosterone to traumatic brain injuries, a significant concern for troops exposed to blast waves from weaponry in training and combat.

While one military health researcher working for the Department of Defense welcomed the increased focus on hormonal health, they questioned why the policy did not address hormonal health for women. This researcher noted that women in the military often face delayed diagnosis and treatment for conditions such as endometriosis and polycystic ovarian syndrome.

Tim Walberg and Rick Allen Investigate Healthcare Reimbursement Models

Congressional Scrutiny and Foundational Needs

The focus on hormonal health arrives as Congress begins to look more closely at the financial impact of specialized therapy industries. In a separate development, House Education & the Workforce Committee Chair Tim Walberg (R-MI) and health subcommittee Chair Rick Allen (R-GA) recently questioned the autism therapy industry’s reimbursement structures. The lawmakers are investigating whether current incentive models are increasing employer health care costs to a degree that warrants congressional action.

As the Pentagon moves forward, critics argue that the military would see greater gains in troop resilience by focusing on foundational needs. If you ask people who train military trainees, we know what builds resilient troops, Phillips told Business Insider. Sleep, training, nutrition, preparation, those things all move performance far more than a prescription.

Readers concerned about individual health markers or potential hormone-related symptoms should consult with a qualified medical professional to discuss appropriate diagnostic testing and evidence-based treatment options tailored to their specific clinical history.
