The US Army has introduced testosterone screening for male soldiers, and early estimates suggest the move could uncover a large number of cases. According to a report from New Scientist, more than 100,000 male soldiers may have low testosterone, a figure that would represent about a quarter of the Army's male personnel.
Low testosterone can affect energy, mood, muscle mass, and overall readiness, making the screening a potentially significant step for military health. The condition is often underdiagnosed in younger populations, and routine screening may help identify soldiers who would otherwise go untreated.
The screening program is newly introduced, so the full scale of the issue is not yet confirmed. The 100,000 figure is an estimate based on current screening data, and actual numbers could shift as more soldiers are tested.
