The Pentagon, under Defense Secretary Pete Hegseth, has introduced a mandate requiring annual testosterone deficiency screening for US service members, a policy that has attracted widespread attention online. The move reflects growing concern within the military about hormonal imbalances affecting troops' mental and physical health, particularly among veterans returning from combat deployments, and marks a shift towards addressing wellbeing issues that have historically been misdiagnosed or overlooked.

The article illustrates the issue through the experience of Chad Robichaux, a former Marine Corps force reconnaissance veteran who served in Afghanistan. Despite maintaining peak physical fitness, he suffered from irritability, depression, fatigue, poor concentration and a persistent sense of dread, and was initially prescribed antidepressants by Veterans Affairs doctors. It was only after seeking independent blood testing that he discovered his hormone levels were severely imbalanced, and addressing this allowed him to stop taking SSRIs, a case cited as underscoring the rationale behind the Pentagon's new screening requirement.
