The Pentagon will conduct testosterone deficiency screenings for active-duty service members who are at least 30 years old and recommend hormonal treatments to boost the U.S. military’s strength, War Secretary Pete Hegseth announced on Wednesday.

Hegseth cast the “High-T” military initiative as part of the War Department’s “sacred duty” to maintain the nation’s “most decisive tactical advantage” in each “individual warfighter” on the battlefield.
