Doctors question evidence behind Pentagon plan for testosterone screening

Pete Hegseth announced that soldiers aged 30 and older in the US military will be screened for low testosterone

The US defense secretary, Pete Hegseth, this week ordered annual testosterone-deficiency screening for active-duty and reserve service members aged 30 and older, which he says will help to maintain military readiness.

But many medical professionals warn it might do nothing of the sort and instead could increase service members' risk of infertility or other consequences if testosterone is prescribed inappropriately.
