Who really needs testosterone?

The Pentagon is moving forward with plans to screen active duty service members for low testosterone, a decision that has sparked fresh debate about the condition and its treatment. At the same time, online platforms are flooded with influencers and clinics pushing testosterone therapy as a fix for everything from fatigue to low libido. The result is a confusing landscape where the line between legitimate medical need and aggressive marketing has become blurred.

So who actually requires this treatment? According to endocrinologists, the answer is far narrower than the internet suggests. True testosterone deficiency, or hypogonadism, is a clinical diagnosis. It requires specific symptoms, such as reduced sex drive, unexplained exhaustion, or loss of muscle mass, combined with blood tests showing consistently low levels, usually checked in the morning. Simply feeling tired or being over 40 does not qualify.

The military's interest makes sense in a narrow context. Special operations and combat roles demand high physical performance, and untreated deficiency could impact readiness. But doctors warn against broad screening. Many men with low numbers on a lab report feel perfectly fine, and treating them offers no proven benefit. Worse, testosterone therapy carries real risks, including increased red blood cell counts, sleep apnea, and potential effects on the prostate.

The social media boom in testosterone content has created a self-diagnosing culture. Men see a video about "low T" and recognize their own everyday stress or poor sleep as symptoms. Clinics, often operating online, are happy to prescribe after a single blood draw, sometimes without a thorough exam. This has led to overuse, with some estimates suggesting a large share of new prescriptions go to men who do not meet standard medical criteria.

For the average person, the takeaway is simple. If you have genuine concerns, see a doctor who will take a full history and run proper tests. Do not rely on a podcast or a sponsored post. The military may need to know who among its ranks has a real deficiency, but for civilians, the answer to who really needs testosterone is usually: fewer people than you think.
