Do You Really Need Testosterone Therapy? An Honest Guide

By C. Erick Kaufman, MD — Medical Director, Holistically Rx

Testosterone therapy is everywhere right now — billboards, podcasts, "low-T" ads promising to turn back the clock. As a physician who prescribes it when it's genuinely indicated, I want to give you the honest version: testosterone can be life-changing for the right man, and useless or even harmful for the wrong one. The difference comes down to a proper diagnosis. Here's how to tell which one you are.

Symptoms Alone Don't Make the Diagnosis

Fatigue, low libido, brain fog, loss of drive — the symptoms that send men to a testosterone clinic are real, but they're also non-specific. They overlap with poor sleep, depression, thyroid problems, medication side effects, and simply being stressed and overworked. That's why symptoms alone are never enough to justify a prescription.

A legitimate diagnosis of hypogonadism requires three things together: consistent symptoms, supportive physical findings, and — the part that's non-negotiable — biochemically confirmed low testosterone.

How the Blood Test Has to Be Done

Testosterone isn't a single fixed number. It follows a daily rhythm, peaking in the morning and drifting down through the day, and it varies from one day to the next. So one random afternoon reading tells you very little.

Done correctly, the test is a morning draw, before about 10 a.m., fasting — and because of that day-to-day variability, it must be repeated on a second separate morning to confirm. Two low morning readings, alongside symptoms and signs, are what support a diagnosis. This two-measurement standard comes straight from the Endocrine Society's clinical practice guideline. One low result is a reason to repeat the test — not a reason to start therapy.

What If Your Levels Are Normal?

Here's the conversation most testosterone ads don't want to have. If your levels come back normal but you still feel run down, the honest answer is that testosterone is not your fix — and taking it anyway can suppress your own production and fertility while adding risk for no benefit.

A responsible clinic will tell you that, and then do the more valuable thing: look for what's actually driving how you feel — sleep, mood, thyroid, metabolic health, medications, stress. Sometimes the answer is a functional-medicine workup rather than a hormone. The clinic willing to tell you that you don't need testosterone is the one you can trust with the decision to prescribe it.

If You Do Qualify: Choosing a Treatment

For men who genuinely have hypogonadism, there are several good options, each with trade-offs:

Injections are effective and inexpensive but can produce peaks and troughs — some men feel a roller-coaster between doses, though newer long-acting forms smooth this out. Gels applied daily give steady levels and are simple, but require care to avoid transferring testosterone to a partner or child through skin contact. Nasal gel avoids that transfer risk entirely but is dosed a few times a day. And modern oral testosterone has quietly solved an old problem: unlike the liver-toxic oral testosterone of decades past, today's formulations are absorbed through the lymphatic system and bypass the liver — their trade-offs are twice-daily dosing with food, possible blood-pressure elevation, and cost. There's no single best choice; the right one fits your body and your life.

The Safety Contract: Monitoring Matters

Starting testosterone responsibly means committing to monitoring. We track your testosterone level (to confirm you've reached a healthy mid-normal range), your PSA and prostate health, and — the one patients rarely expect — your red blood cell count (hematocrit). Testosterone stimulates red-cell production, and the most common reason we pause or lower a dose isn't the prostate; it's blood that's grown too thick, which raises clot risk. These are checked at baseline, again a few months in, and periodically after that.

Is Testosterone Safe for Your Heart?

For years this was the big worry, based on older, weaker studies. The question was finally tested head-on in the TRAVERSE trial (New England Journal of Medicine, 2023), which followed roughly 5,200 middle-aged and older men who had both hypogonadism and existing cardiovascular risk. The headline result was reassuring: testosterone therapy did not increase major cardiac events — heart attack, stroke, or cardiovascular death — compared with placebo. It wasn't a completely clean bill of health (the study saw somewhat more atrial fibrillation, blood clots in the lungs, and kidney injury), which is exactly why monitoring matters. But the modern, evidence-based takeaway is that for men who genuinely need it, properly monitored testosterone has not been shown to harm the heart.

The Bottom Line

Testosterone therapy is a real medical treatment — not a lifestyle supplement, and not something you should have to talk a clinic out of over-prescribing. If you have genuine symptoms, insist on a proper morning, repeated blood test and an honest interpretation of the result. If you qualify, treatment is safe and effective when it's monitored. And if you don't, the right clinic will help you find what's actually going on.
