US military to start testosterone testing, Hegseth says

Dr Mohit Khera, who led a US Food and Drug Administration (FDA) expert panel last year on screening and testosterone utilisation in the military, told the BBC on Wednesday that all men over 30 should get screened because it is the top marker of a person's overall current and future health.

Hegseth's announcement comes after US Health Secretary Robert F Kennedy Jr and other administration officials have sought to remove barriers for medical professionals to prescribe men testosterone.

Taking testosterone for non-medical reasons, like artificial muscle enhancement without a doctor's prescription, is strictly prohibited in the military.
