In a significant policy shift, Defence Secretary Pete Hegseth has unveiled a new testosterone screening programme aimed at U.S. service members aged 30 and above. This initiative seeks to identify deficiencies in testosterone levels and provide hormone replacement therapy for those diagnosed with low testosterone, colloquially referred to as “low-T”. The screening is part of an effort to enhance performance and longevity among armed forces personnel.
During a recent social media announcement, Hegseth emphasised the importance of maintaining the “biological foundation required to sustain the fight”. He referred to military personnel as “warfighters” and highlighted the demanding nature of their roles, stating, “Every single day, you are pushed to your absolute physical and mental limits to master the profession of arms.”

The screening will be integrated into the annual “periodic health assessments” that soldiers undergo. While mandatory for those aged 30 and older, younger service members will have the option to participate if they wish. Individuals found to have low testosterone levels will be afforded the opportunity to explore hormone replacement therapy as part of their healthcare options.
According to Hegseth, this programme is not intended to promote artificial enhancement; rather, it is designed to deliver the highest standard of medical care to military personnel. He asserted, “We owe our warriors the absolute best medical care in the world, and this programme delivers on that obligation.” The goal, he explained, is to ensure that soldiers remain resilient and capable not just throughout their military careers, but also in their lives after service.
The Defence Secretary underscored that the modern battlefield is unforgiving and demands optimal psychological and physical readiness from service members. He stated, “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.”

Despite the emphasis on inclusivity in his address, it remains unclear how this testing will be applied to female soldiers and those who do not produce testosterone. Hegseth refrained from using gender-specific language when discussing the screening, raising questions about its applicability across the entire military demographic.
Medical experts have noted that while testosterone therapy may assist in mitigating some of the negative consequences associated with aging, such as decreased muscle mass and energy levels, there are potential risks involved. The Mayo Clinic has warned that testosterone medications can lead to negative emotional side effects, including increased agitation, irritability, and even suicidal thoughts in some individuals. Furthermore, while some men report feeling rejuvenated on testosterone, medical guidance suggests there is insufficient evidence to warrant its use in otherwise healthy males.
Hegseth’s announcement follows a series of controversies surrounding his management of U.S. troops. A recent investigation by the New York Times claimed he had obstructed the promotion of several Navy officers, including women and individuals from minority backgrounds, prompting backlash regarding diversity and inclusion within military ranks.
The promotion list from May was notably lacking female officers, despite women constituting around 21% of active-duty Navy members. The report also highlighted that only a couple of officers of colour made the list, raising further concerns about representation within military promotions.
As the Defence Department prepares to implement this new screening initiative, the response from service members and healthcare professionals alike will be closely monitored. The implications of the testosterone programme will likely resonate within the armed forces as efforts to enhance operational effectiveness and soldier well-being are continually evaluated. With service members’ health at the forefront of military strategy, the forthcoming assessment of this initiative may reveal much about the evolution of military healthcare in the coming years.
