Why Your Doctor Won't Prescribe TRT (Even When You Need It)

"Your testosterone is normal" is one of the most-heard sentences in men's health, and it is usually said sincerely by a doctor who is not doing anything wrong. That is what makes it frustrating. The refusal is rarely about your individual case. It is about how reference ranges are built, how physicians were trained, how long an appointment lasts and what insurance pays for. Understanding which of those is operating tells you what to do next.

A reference range is a survey, not a standard

This is the piece almost nobody explains. A laboratory reference range is not a statement about what is healthy. It is a description of where the middle of a measured population sat — conventionally the central 95%, with the bottom 2.5% and top 2.5% cut off. Harmonised ranges for total testosterone run from roughly 264 to 916 ng/dL (Travison et al., JCEM 2017).

Look at what that population contains. It includes men who are obese, sedentary, chronically short of sleep, drinking heavily, and metabolically unwell — because those men exist in large numbers and were measured along with everyone else. "Normal" by laboratory convention therefore means "common in the population we sampled," which is not the same claim as "adequate for you." A range built from a healthier reference group sits tighter and higher, typically around 700-900 ng/dL.

The gap between those two framings is where most of these conversations get stuck. A man at 380 ng/dL with clear symptoms is inside the range and outside anything resembling optimal. His result prints without a flag, the flag is what the visit is structured around, and the conversation ends there.

What a single "normal" number can hide

Even when total testosterone genuinely is adequate, the number can be doing a poor job of describing what tissue actually sees. Most circulating testosterone is bound to sex hormone-binding globulin and largely unavailable. SHBG rises with age, thyroid excess, liver disease and some medications, and falls with obesity and insulin resistance. A man with high SHBG can have a comfortable total and a genuinely low free fraction — the symptomatic one — and nothing on a basic panel will say so.

Timing compounds it. Testosterone follows a diurnal pattern, highest in the morning, and a level drawn at 3pm after a poor night is not comparable to one drawn at 8am. Acute illness, recent hard training and short sleep all suppress it temporarily. A single afternoon draw is a snapshot of a moving quantity, and it is the most common way this evaluation goes wrong in both directions. Free versus total testosterone and what SHBG is doing cover the mechanics.

Training that has not been updated

Most practising physicians formed their view of testosterone therapy during a period when several beliefs were dominant:

• That it increased cardiovascular risk — a concern the TRAVERSE trial has since addressed directly (Lincoff et al., NEJM 2023)
• That it caused prostate cancer — not supported by subsequent meta-analysis
• That estradiol in men should be suppressed — now understood to be actively harmful in most cases
• That treatment starts below 300 ng/dL and otherwise does not start at all

Medical practice updates slowly by design; the same conservatism that prevents physicians chasing every new finding also means a settled belief takes a decade to shift. A physician holding the 2013 position is not negligent. They are simply working from the version of the evidence they learned, and nothing in a routine week forces them to revisit it.

The structural reasons, which are the real ones

Three constraints do most of the work here, and none of them are about you.

Scheduling. Testosterone is a Schedule III controlled substance. That brings DEA registration, prescription monitoring obligations and a different administrative load from writing an ordinary prescription. Some practices simply do not engage with controlled substances beyond the minimum. Some physicians are wary of their controlled-substance prescribing volume rising for any reason.

Time. A primary care visit runs twelve to fifteen minutes and typically has an agenda already. A genuine hormone conversation — pattern of symptoms, correct draw timing, SHBG and free testosterone, thyroid, fertility intentions, haematocrit monitoring, what happens if it does not work — needs half an hour that does not exist. Faced with that, deferring to the unflagged lab value is the only move the clock allows.

Reimbursement. Insurance pays well for diagnosis, procedures and chronic disease management. It pays poorly for interpretive work: reading a panel in context, titrating a dose, and following someone for months to see whether it worked. The care model that hormone therapy requires is the one the payment model funds least.

When your doctor is right to say no

This deserves stating, because the internet version of this article usually skips it. Sometimes the refusal is correct, and taking it seriously is what separates a real evaluation from a rubber stamp.

A low testosterone level is a finding, not a diagnosis, and several things produce it that are better treated at the source. Untreated obstructive sleep apnoea suppresses testosterone and improves when treated. Significant obesity does the same through aromatisation in adipose tissue. Opioids, glucocorticoids and heavy alcohol suppress the axis directly. Very low levels with low LH and FSH, or any visual field disturbance, headaches or galactorrhoea, point at the pituitary and need imaging and a prolactin level before anything else. And if you intend to father children in the near term, exogenous testosterone suppresses sperm production — a fact that should be raised before the first prescription, not after.

A physician who declines for one of those reasons and explains it is doing the job. A physician who declines because the number printed without a flag is not. The two are easy to tell apart: the first gives you a reason and a next step.

What to do about it

1. Get the panel drawn properly. Between 7 and 10am, fasted, on two separate mornings — a single result is not enough to act on in either direction.
2. Get the right markers. Total and free testosterone, SHBG, LH and FSH, sensitive estradiol, full thyroid, haematocrit and PSA where age-appropriate.
3. Ask for the numbers, not the summary. "Normal" at 350 and "normal" at 850 are the same word describing different situations. You are entitled to the values.
4. Bring a structured case back to your physician. Symptom pattern, duration, two morning draws, family history, and a specific ask. Some will engage with that who would not engage with "I think my testosterone is low."
5. Rule out what is rule-out-able first. Sleep, alcohol, medications, weight. Not because they are always the answer, but because if they are, therapy is the wrong tool and you will find that out either way.
6. If the answer is still no, take it to someone who does this work. An endocrinologist, a men's health practice, or a telehealth service with real physician oversight — how to choose one and whether telehealth hormone care is legitimate both cover what to look for and what to avoid.

Bottom line

If your physician declined and the reason given was that your number fell inside a reference range, you have not been evaluated — you have been screened against a population survey. Get two properly timed morning draws with SHBG, free testosterone and the pituitary markers, take the reversible causes seriously, and then have the conversation with someone whose practice is built to have it. The gap between primary care and specialty care on hormones is wider than it should be. It is also, at this point, straightforward to cross. The symptom checklist is a reasonable starting point, and the 60-second assessment routes the case to a physician who can order the full panel.
