WASHINGTON—Saying the government was committed to helping military personnel reinforce their existing outward identity, Pentagon officials announced a plan Wednesday that would cover the cost of hormone treatment for servicemembers doubling down on their biological sex. “Effective immediately, the Defense Department will begin financing the hormone therapy of armed forces members who wish to recommit to the sex they were assigned at birth,” said Defense Secretary James Mattis, adding that it was only right to provide assistance to soldiers who made the difficult decision to intensify the characteristics of the body they currently possess with a protocol of testosterone injections. “U.S. military health plans will now fully compensate any serviceman who would feel more comfortable—indeed, feel truly themselves—if his body hair was twice as thick and his voice was twice as deep as it is currently.” Mattis went on to say that female soldiers, meanwhile, were ineligible for the plan but could occasionally take a dose of testosterone if they wanted.
