Could a simple hormone test make soldiers stronger and healthier?
That’s the idea behind a new policy announced by US Defence Secretary Pete Hegseth.
Under the plan, active-duty and reserve troops aged 30 and older will automatically be screened for testosterone deficiency during their annual health checks.
Those with low levels can choose hormone replacement therapy, while testing will be optional for service members under 30.
Hegseth said the goal is straightforward: keeping troops “strong, resilient and capable” throughout their military careers and beyond.
He also stressed the programme “is not about artificial enhancement.”
The Pentagon says the policy takes effect immediately.
Officials have not clarified whether it will also include female troops or if hormone therapy related to menopause will be considered.
That uncertainty has sparked criticism, with Democratic lawmakers urging equal access to hormone testing for women.
Policy Divides Opinion
Experts, however, say the screenings could have real health benefits if used correctly.
Dr Mohit Khera, a urology professor at Baylor College of Medicine, said many young men have low testosterone levels.
He said this puts them at a disadvantage in terms of muscle mass and energy.
But he warned treatment should only follow proper diagnosis, noting it can affect fertility and may carry cardiovascular risks.
Supporters see the move as boosting military readiness. Critics call it another political flashpoint.
Either way, one hormone is now at the centre of a much bigger debate.
