Is Testosterone Therapy Safe and Effective? What We Know
A December FDA expert panel advocated expanding testosterone therapy beyond classic hypogonadism, branding it a multibillion‑dollar preventive‑care opportunity. Recent evidence, notably the 5,200‑patient TRAVERSE trial, found no rise in cardiovascular events among high‑risk men receiving therapeutic doses. However, high‑dose use—often seen in anabolic‑steroid abuse—remains linked to severe health risks, including a three‑fold increase in mortality. Regulatory momentum is building, with the FDA now inviting applications for low‑libido treatment and potential re‑classification of the hormone.
