The Pentagon has introduced mandatory testosterone screening for U.S. military personnel aged 30 and over, with the new policy expected to take effect immediately.

The guidance, issued on Wednesday, sets out procedures for identifying and treating hormone-related problems among active-duty and reserve service members.

The Pentagon says the measures are intended to improve military readiness by addressing issues linked to fatigue, energy levels and hormonal health.

Men aged 30 and over will be required to have blood tests to check their testosterone levels. Younger men will only be tested at their request or if doctors identify warning signs.

The policy follows Defence Secretary Pete Hegseth's announcement in July. Hegseth has promoted testosterone use, raising questions among medical experts over the scientific basis for widespread screening.

The U.S. Food and Drug Administration is due to hold an expert meeting in September to discuss the medical use of testosterone.

Different approach for women

Women will not undergo routine testosterone blood tests. Instead, doctors will screen for symptoms such as fatigue and disrupted menstrual cycles, which can be linked to hormonal problems and low energy availability.

The guidance also outlines when testosterone may be prescribed off-label to women, including postmenopausal women with unusually low sexual desire.

Some doctors have warned that widespread testing could lead to unnecessary or potentially harmful treatment. They also say there is limited evidence that universal testosterone screening would improve military readiness.
