Testosterone deficiency screening and replacement therapy will soon be on offer for active-duty service members as a military readiness initiative as part of a new military readiness program announced by War Secretary Pete Hegseth.Hegseth announced Wednesday a new “High-T” military initiative that will make testosterone blood tests a required part of military physicals for service members over 30 and hormonal replacement therapy an optional treatment for members with deficiencies.Testosterone is a critical steroid hormone that is essential for male reproductive development, but it is also responsible for maintaining muscle mass and bone density, as well as mental health.

As men age, testosterone levels gradually decline, dropping roughly 1% per year after age 30, which can lead to health complications and lower physical capacity.Hegeseth said in his video address that the new screening program, which will be optional for service members under age 30 as well, is intended to ensure “you have the right testosterone level to operate at your absolute best.”“We have a sacred duty to maintain that advantage, which is why we must constantly look for new ways to optimize your performance, your resilience, and your long-term health,” Hegeseth said.But testosterone replacement therapy is not without risks. The Food and Drug Administration is currently reevaluating evidence on the links between TRT and prostate cancer, but testosterone therapy can also increase cardiovascular risks.Here is everything to know about the new “High-T” initiative.
