More than half of all testosterone prescriptions are written by primary care physicians, so your regular doctor is often the first and only stop. But depending on your situation, you may end up seeing a urologist, an endocrinologist, or a provider at a men’s health clinic instead. The right choice depends on how straightforward your case is and whether you need specialized care.
Primary Care Doctors Handle Most Cases
Family medicine doctors and internists prescribe the majority of testosterone replacement therapy in the United States. If you have symptoms like low energy, reduced sex drive, or mood changes, your primary care doctor can order the blood work, make the diagnosis, and start treatment without a referral. For many men, especially those with a clear-cut case of low testosterone and no complicating health conditions, there’s no need to see anyone else.
Your primary care doctor will also manage the ongoing monitoring that testosterone therapy requires: blood draws every 6 to 12 months to check red blood cell concentration (which testosterone can push too high) and periodic prostate screening based on your age and risk factors. This is routine work that fits well within a general practice.
When You’d See a Urologist
A urologist specializes in the male reproductive system and is the most common specialist involved in testosterone therapy. Your primary care doctor would typically refer you to one if a prostate concern comes up during evaluation, such as an elevated PSA level above 4 ng/mL or an abnormal prostate exam. If your PSA rises more than 1.4 ng/mL within the first 12 months of treatment, that also warrants a urology referral.
Urologists are also the better choice if you’re trying to preserve fertility. Standard testosterone therapy can suppress sperm production, and urologists are trained to manage alternative approaches or combination protocols that address both low testosterone and fertility goals. Men with testicular abnormalities found during the physical exam, such as atrophy, masses, or varicoceles, are also better served by a urologist from the start.
When You’d See an Endocrinologist
Endocrinologists specialize in the hormonal system as a whole. You’re most likely to see one if your low testosterone has an unusual or complex cause: a pituitary gland problem, a genetic condition, thyroid disease, or adrenal disorders that affect multiple hormones at once. If your primary care doctor runs the standard tests and the picture doesn’t add up, an endocrinologist can dig deeper into why your body isn’t producing enough testosterone rather than simply replacing what’s missing.
Some insurance plans specifically require that an endocrinologist or urologist make the diagnosis before they’ll cover treatment. This is worth checking before your first appointment, since it could affect which doctor you see and in what order.
Men’s Health Clinics: Convenient but Variable
Direct-to-consumer men’s health clinics have grown rapidly, and many advertise testosterone therapy as a core service. These clinics are convenient, often offering same-day treatment and minimal wait times. But a Harvard Health review of 233 such clinics found significant concerns: most did not follow standard diagnostic protocols for low testosterone, and most did not have a urologist or endocrinologist on staff. The primary providers were often nurse practitioners or physician assistants, and it wasn’t always clear whether a physician with men’s health expertise was supervising their care.
These clinics also tend to operate outside insurance networks. Among those that listed pricing, testosterone therapy cost $80 to $500 per month out of pocket. That adds up quickly for a treatment most men stay on indefinitely. If you go this route, ask specifically who is overseeing your care, whether they follow established diagnostic guidelines, and what monitoring schedule they use.
How Low Testosterone Is Diagnosed
Regardless of which doctor you see, the diagnostic process follows the same standard. The American Urological Association defines low testosterone as a total testosterone level below 300 ng/dL, confirmed on two separate blood draws taken on different days. Both samples need to be drawn in the morning, preferably before 10:00 a.m. or within three hours of waking, and ideally while fasting. Testosterone levels fluctuate throughout the day and peak in the early morning, so afternoon blood draws can produce misleadingly low results.
Beyond the blood work, your doctor will look for physical signs that support the diagnosis: reduced facial and body hair growth, breast tissue enlargement, testicular atrophy, and increased waist circumference. These findings, combined with symptoms and confirmed low lab values, build the case for treatment.
What Insurance Requires
Many insurance plans require prior authorization before covering testosterone therapy. The documentation requirements are specific. Plans typically ask for proof of two morning blood draws showing testosterone below 300 ng/dL, confirmation that the prescribing doctor has investigated the underlying cause, and evidence that the patient has symptoms consistent with low testosterone. Some plans require the prescription to come from an endocrinologist or urologist specifically, not a primary care doctor.
Coverage will not be approved if the therapy is intended to enhance athletic performance or if it’s being used alongside another testosterone product. If your primary care doctor’s prescription gets denied, a referral to a specialist for a formal diagnosis may be what’s needed to get approval. It’s worth calling your insurance company before your first appointment to understand what documentation they need, since this can save months of back-and-forth.
Choosing the Right Starting Point
For most men, the simplest path is starting with your primary care doctor. They can order the initial blood work, evaluate your symptoms, and determine whether your case is straightforward enough to manage in their office or whether a specialist referral makes sense. You don’t need to go directly to a urologist or endocrinologist unless you already know you have a complicating condition like a pituitary disorder, a history of prostate cancer, or active fertility concerns.
If you don’t have a primary care doctor or want faster access, a urologist is a reasonable first specialist to see, since they handle the full scope of testosterone management from diagnosis through long-term monitoring. Endocrinologists are the right call when the hormonal picture is complicated or when multiple hormone systems seem involved. Men’s health clinics offer speed and accessibility, but you’ll want to verify the quality of care and understand the ongoing costs before committing.
