Pete Hegseth, United States Secretary of War (née Defense), is apparently looking to make America’s soldiers high T again. On Wednesday, Hegseth announced a new policy that will mandate testosterone screening for many service members. The screening will be universally implemented as part of the annual check-up for people over 30, though younger service members can request it as well. The initiative is the latest instance of the Trump administration’s fixation on low testosterone as a major cause of health issues in men—an idea backed by shaky evidence at best. “We owe our warriors the absolute best medical care in the world, and this program delivers on that obligation,” said Hegseth in a video posted on X Wednesday, aptly titled “The High-T Department of War.” A real but overblown issue Men do typically experience a gradual decline of testosterone as they age. And some men can experience symptoms linked to low testosterone, such as lowered sex drive as well as worsening mental health and energy. Studies have consistently shown that testosterone replacement therapy (TRT) can help these men, and more recent research has eased concerns that TRT can cause serious complications like heart attack and stroke.
