Getting a testosterone prescription requires blood work showing levels below 300 ng/dL on two separate morning tests, along with symptoms that point to a deficiency. The process typically involves a few doctor visits, lab draws, and a conversation about whether treatment makes sense for your situation. Here’s what each step looks like in practice.
Start With the Right Doctor
Your primary care doctor can order the initial blood work, but if your results come back low, you’ll likely be referred to a specialist. Urologists and endocrinologists are the two types of doctors who most commonly evaluate and manage testosterone therapy. Urologists tend to see men with sexual symptoms like erectile dysfunction or low libido, while endocrinologists focus more broadly on hormonal conditions. Either can prescribe testosterone if the labs and symptoms warrant it.
Telehealth clinics that specialize in hormone therapy have also become common. These can be convenient, but make sure any provider you work with orders proper lab work and doesn’t skip the diagnostic steps outlined below. A legitimate provider will never prescribe testosterone based on symptoms alone.
What Happens at Your First Appointment
Your doctor will ask about specific symptoms associated with low testosterone. The ones that carry the most weight in a clinical evaluation include:
- Low sex drive or problems getting or maintaining erections
- Fatigue and sleep problems, including insomnia
- Loss of muscle size and strength
- Increased body fat, particularly around the midsection
- Mood changes such as depression or difficulty concentrating
- Bone loss
Some men with low testosterone have no noticeable symptoms at all, which is one reason the diagnosis can’t rest on how you feel. Your doctor will also review your medical history for conditions that could either cause low testosterone (like obesity, pituitary disorders, or certain medications) or rule out treatment entirely.
The Blood Tests You’ll Need
The key number is your total testosterone level. The American Urological Association uses 300 ng/dL as the diagnostic cutoff: levels consistently below that support a diagnosis of testosterone deficiency. For reference, the normal range for men aged 19 to 39 is roughly 264 to 916 ng/dL, based on a large harmonized study published by the Endocrine Society.
Two important rules apply to the blood draw. First, it needs to happen in the early morning, typically before 10 a.m., because testosterone peaks during those hours and drops later in the day. A midday test could show a falsely low reading. Second, you need two low results on separate days. A single low number isn’t enough for a diagnosis or a prescription. Some guidelines also recommend fasting before the test, though recent research suggests eating beforehand may not significantly change results.
Your doctor will order a total testosterone test as the primary measure. Free testosterone (the small fraction not bound to proteins in your blood) is sometimes checked as a secondary test, but the AUA specifically recommends against using it as the primary diagnostic tool because there’s no consistent threshold that reliably predicts symptoms or treatment response.
Depending on your results, your doctor may also check other hormones like LH and FSH to determine whether the problem originates in the testes or the brain’s signaling system. This distinction matters because it can change the treatment approach.
What Qualifies You for a Prescription
Two confirmed morning testosterone levels below 300 ng/dL, combined with symptoms, is the standard most doctors and insurance companies use. Aetna’s policy, which mirrors many major insurers, explicitly requires at least two confirmed low morning levels before covering testosterone therapy. If your levels are borderline, say 310 or 320 ng/dL, most providers will not prescribe treatment even if you have symptoms.
Certain health conditions can disqualify you from testosterone therapy or require extra caution. Your doctor will evaluate factors like your red blood cell count, prostate health, and cardiovascular history before writing a prescription. Men actively trying to conceive are generally advised against standard testosterone therapy because it suppresses sperm production.
Forms of Testosterone Available
If your labs and symptoms meet the criteria, your doctor will discuss which delivery method fits your lifestyle. The FDA has approved several options:
- Injections are the most common and least expensive. You or your doctor inject testosterone into the muscle, typically every one to two weeks.
- Topical gel is applied daily to the shoulders or upper arms. It maintains steadier hormone levels but requires care to avoid skin-to-skin transfer to others.
- Patches are worn on the skin and replaced daily. They can cause irritation at the application site.
- Buccal tablets are placed against the upper gum twice daily. They’re less commonly used but avoid the injection and skin-transfer concerns.
Subcutaneous pellets implanted under the skin every few months are another option, though they aren’t as widely offered. Your doctor’s recommendation will depend on your comfort level, insurance coverage, and how important convenience versus cost is to you.
Insurance and Out-of-Pocket Costs
Most insurance plans cover testosterone therapy when the diagnosis follows proper clinical guidelines: two documented low morning levels plus a confirmed diagnosis of hypogonadism. Your insurer will likely require prior authorization, which means your doctor’s office submits your lab results and clinical notes for approval before the pharmacy fills the prescription.
If your insurance denies coverage or you’re paying out of pocket, injectable testosterone cypionate is the most affordable option, often running $30 to $50 per month at a retail pharmacy. Gels and patches are significantly more expensive without insurance, sometimes several hundred dollars monthly, though manufacturer coupons and generic versions can reduce that.
Monitoring After You Start
A testosterone prescription isn’t a one-time event. Your doctor will schedule follow-up labs to make sure the therapy is working safely. A typical monitoring schedule looks like this: blood work at 3 months, 6 months, and 12 months after starting, then at regular intervals going forward.
The main things your doctor tracks are your red blood cell count (testosterone can thicken the blood, raising the risk of clotting), blood sugar, liver function, and lipid levels. Red blood cell counts are usually checked every six months once you’re stable, and a broader metabolic panel including cholesterol is done annually. If your red blood cell count climbs too high, your doctor may lower your dose or pause treatment temporarily.
You’ll also have your testosterone level rechecked to make sure your dose is putting you in the target range. If your symptoms haven’t improved after a few months at adequate levels, your doctor may reevaluate whether testosterone deficiency was the primary issue or whether something else is contributing.
