Hegseth’s ‘High-T’ testosterone initiative: What to know
Washington Examiner · RC · trust 63/100

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.

Roughly a quarter of men in the United States, about 33 million, according to the American Urological Association , meet the standards for testosterone deficiency, which is sometimes referred to as “low-T.”
Testosterone deficiency in men is defined as having a total serum testosterone level of less than 300 nanograms per deciliter. Although urine samples can be used to detect the presence of synthetic steroids as part of anti-doping screening, medical-grade testing for testosterone deficiency requires a blood sample.
Although testosterone deficiency is typically associated with older males, roughly 20% of adolescent and young adult males between the ages of 15 and 39 also suffer from low testosterone.
Obesity, diabetes, and high blood pressure are strongly correlated with low testosterone that is not caused by another underlying health condition, such as a genetic disorder affecting the testicles.
Several studies suggest that military service members, especially those deployed in combat, are at a higher risk of developing low testosterone and could benefit physically and mentally from TRT.
Military personnel can express up to 65% less testosterone due to the stress applied in military training and active duty, including a lack of sleep and nutrition.
In 2019, the Army Research Institute of Environmental Medicine conducted a short-term study demonstrating that TRT for a 28-day period resulted in a reduced rate of weight loss and improvements in maintaining lean muscle mass for servicemen in the field.
Other studies suggest that improved testosterone levels might improve service members’ risk of developing post-traumatic stress disorder, depression, or other adverse mental health outcomes following a tour of duty.
“By addressing these health markers early, we’re keeping you on the leading edge of lethality and giving you the same level of support that you give this nation: the absolute best,” Hegseth said, addressing service members.
Men’s wellness influencers have increasingly embraced testosterone replacement as a performance-enhancing medical treatment, with supplemental hormones being touted as a “cheat code” for bodybuilding and other sports.
Hegseth specifically said in his video address that the initiative is “not about artificial enhancement” but rather boosting the male vitality of the military’s fighting force.
“It’s about restoring and optimizing your natural capabilities, protecting your longevity, ensuring you have the biological foundation required to sustain the fight,” Hegseth said.
TRT is also a central treatment for female-to-male transgender people, or biological women seeking to become more masculine.
Trump administration officials and Hegseth himself have lambasted hormone replacement therapy for transgender patients as chemical castration due to the negative effects of excess testosterone on the female reproductive system or estrogen on the male reproductive system.
The Pentagon declined the Washington Examiner ’s request for comment on the difference between TRT for biological males versus biological females who identify as male.

Testosterone therapy for age-related changes, not caused by an underlying disease, is relatively new.
Beginning in 2015, the FDA required TRT product labels to include information that the risks to cardiovascular health, including blood clots, did not outweigh the possible benefits for testosterone treatment without an underlying condition.
But last month, the FDA announced it would begin the rulemaking process to revise labeling information on TRT’s connection to prostate cancer and reevaluate evidence of the cardiovascular risks.
A landmark 2023 clinical trial of more than 5,200 men found no meaningful increase in risk of major adverse cardiovascular events while on TRT, including heart attack and stroke.
But the FDA’s policy changes have not yet been finalized and are still subject to public comment.
The Pentagon declined the Washington Examiner ’s request for comment on the new initiative, including whether the War Department is working with the FDA and the Department of Health and Human Services.
