Defense Secretary Pete Hegseth has announced that the US military will start testing testosterone levels of service members as part of a new initiative to "restore and optimize" their capabilities.

In a video posted on X titled "High-T Department," Hegseth stated he is authorizing the screening program to ensure troops "have the right testosterone levels to operate at your absolute best."

The program mandates annual screening for all active duty and reserve personnel aged 30 and older, while younger service members can request testing voluntarily. Those found with low testosterone levels will be offered voluntary testosterone replacement therapy.

Pentagon spokesperson Sean Parnell confirmed in a statement that the mandatory screening is effective immediately for personnel aged 30 and above.

Dr. Mohit Khera, a professor of urology at Baylor College of Medicine who led a US Food and Drug Administration (FDA) expert panel on military testosterone screening last year, told the BBC that all men over 30 should be screened as testosterone is a key marker of overall current and future health. He noted, "The key here is that many young men have low testosterone levels, which puts them at a disadvantage in terms of muscle mass, energy, and that could be an issue if you are in combat."

Hegseth emphasized the military's commitment to providing "the absolute best medical care in the world," adding that taking care of long-term health ensures service members remain strong and capable not only for deployments but for life after military service.
