US Defense Secretary mandates testosterone screening for service members over 30

The Pentagon will implement annual screening for testosterone deficiency among U.S. service members aged 30 and older, Defense Secretary Pete Hegseth announced Wednesday. This new policy aims to ensure military personnel maintain peak physical and mental performance.

Hegseth stated in a video message that the screening program is designed to guarantee service members have the necessary testosterone levels to "operate at your absolute best." The testing will be conducted annually as part of periodic health assessments. Service members younger than 30 will have the option to undergo testing voluntarily.

“

I'm authorizing a new screening program for testosterone deficiency for our service members, ensuring you have the right testosterone levels to operate at your absolute best.

"We owe our warriors the absolute best medical care in the world, and this program delivers on that obligation," Hegseth said. He emphasized that maintaining long-term health is crucial for service members, ensuring they remain strong, resilient, and capable not only for deployments but also for their lives after military service.

The policy addresses concerns that the high operational tempo and stress inherent in military service can negatively impact testosterone levels. Researchers have noted a potential link between these factors and hormonal dysregulation, mood changes, and cognitive issues, particularly in special operations communities where a syndrome known as "The Operator Syndrome" has been observed. This syndrome is thought to stem from chronic stress, blast exposure, traumatic brain injuries, and sleep disruptions.

While the Pentagon has not yet released detailed guidance on the policy, the Defense Health Agency referred inquiries to the Pentagon. The definition and prevalence of low testosterone can vary significantly, with studies showing a wide range depending on the criteria used.

The high operations tempo and high stress that these service members go through can actually decrease testosterone, sometimes acutely and sometimes even in the long term.
