Hegseth's plan to screen military members for low testosterone raises concern for doctors: "Not a performance drug"

A day after Defense Secretary Pete Hegseth announced that U.S. service members over the age of 30 will be annually screened for "testosterone deficiency," doctors are expressing skepticism of the program and its goals.
Hegseth said all service members over 30 will be screened as part of their regular health assessments, and that younger ones will have the option of being tested to ensure that they "have the right testosterone levels to operate at your absolute best." If they are recommended for treatment, they'll have the option to receive testosterone replacement therapy.
Hegseth has commented frequently on the physical standards of the military, connecting appearance and masculinity to combat readiness. Hegseth did not say what the new policy might mean for female service members, and other details have not yet been announced.
Doctors flagged a range of concerns about the policy, which is likely to be costly to implement. National organizations including The Endocrine Society and the American College of Physicians recommend against general screenings for testosterone levels, which can fluctuate based on age, lifestyle and even the time of day.
"Testosterone in the normal range is not a performance drug," said Dr. Céline Gounder, CBS News medical correspondent and editor-at-large for public health at KFF Health News. "For a man whose level is genuinely low, replacement can help libido and mood a little. It has not been shown to sharpen thinking, fix fatigue, or make a healthy 30-year-old a better soldier."
"No link to how masculine they are or feel or look"
Testosterone is a hormone naturally produced by the body. It helps maintain muscle and bone mass, and impacts mood and energy levels. It impacts libido and supports sperm production in men. But it isn't inherently linked to an increase in strength or capability, said Dr. Marcus Goncalves, director of the Holman Division of Endocrinology, Diabetes, and Metabolism at NYU Langone Health.
