WASHINGTON, Sept 17 (Reuters) – The Pentagon is reinstituting a mandatory testing program for testosterone deficiency ​among US service members age 30 ‌and older, a spokesperson said on Thursday, bringing back a program that many medical experts have described as unnecessary and potentially ‌harmful.

US ​Defense Secretary Pete Hegseth, ⁠who has promoted the ⁠use of testosterone to improve military readiness, first announced the screening mandate in July.

Under the announced guidance, women ​were also set to be screened through a questionnaire and could then ⁠move to treatment ⁠for conditions related to hormonal ​imbalances.

In early September, however, the Pentagon temporarily ​rescinded the published medical guidance for the ‌testosterone screening “to allow for updates.”

The latest move lifts that pause, allowing testing to go forward. It was not ⁠immediately clear what, if any, updates had been made to the original policy.

“Effective immediately, this ⁠guidance addresses ‌male testosterone deficiency, establishing ⁠uniform screening and treatment pathways,” ​Pentagon ‌spokesperson Sean Parnell said in ​a statement.

Medical ⁠professionals have warned that testosterone, if prescribed inappropriately, could increase service members’ risk of infertility or lead to other health consequences.
