Defense Secretary Hegseth announces mandatory testosterone screening for US troops

Defense Secretary Pete Hegseth announced mandatory annual testosterone screening for U.S. troops aged 30 and older, with voluntary treatment options. The policy, aimed at enhancing performance, has divided medical experts. Supporters see it as a way to identify health issues, while critics call it "crazy," citing risks of overtreatment and test inaccuracies. The move aligns with the Trump administration's broader support for testosterone therapy.

Mandatory testosterone screening policy

• ▪Troops under the age of 30 can voluntarily request to be tested for testosterone levels
• ▪The screening will be part of the annual periodic health assessment for service members
• ▪U.S. Defense Secretary Pete Hegseth announced on July 15, 2026, a policy of mandatory annual testosterone screening for troops aged 30 and older

Testosterone replacement therapy debate

• ▪The announcement drew criticism from Democrats who contrasted it with the administration's ban on transgender service members who use hormone therapy
• ▪Testosterone replacement therapy has proven benefits for men with a diagnosed deficiency who experience symptoms like fatigue, low libido, and mood disorders
• ▪If diagnosed with low testosterone, troops can voluntarily decide whether to accept recommended hormone replacement treatment

Medical expert disagreement

• ▪Medical experts are divided on the policy, with some calling it promising and others describing it as "crazy."
• ▪Dr. Abraham Morgentaler of Harvard Medical School supports the screening, arguing it could identify important medical conditions not otherwise detected
• ▪Current guidelines from major American medical organizations recommend against routine screening for testosterone levels
• ▪Dr. Adrian Dobs of Johns Hopkins University opposes the policy, citing concerns about test inaccuracy, the broad range of normal levels, and the risk of overtreatment

Trump administration testosterone support

• ▪The FDA recently revised testosterone product labels, removing a disproven warning about prostate cancer risk
• ▪Health Secretary Robert F. Kennedy Jr. has publicly stated that he takes testosterone
• ▪The policy reflects the Trump administration's broader support for testosterone replacement therapy for men

Military-specific health considerations

• ▪A formal diagnosis of testosterone deficiency requires both consistent symptoms and repeatedly low morning testosterone levels, not just one lab result
• ▪Dr. Helen Bernie of Indiana University suggested screening may have value for military personnel due to occupational demands like intense training, stress, and sleep deprivation

Testing accuracy concerns

• ▪Experts note that the variability of testosterone assays and the broad range of normal levels make it difficult to pinpoint who needs replacement therapy
• ▪A significant side effect of testosterone therapy is that it can cause a man's body to stop its own production, impacting sperm production
