Getting testosterone therapy starts with blood work confirming your levels are low, followed by a prescription from a qualified provider. The process typically takes a few weeks from your first appointment to starting treatment, but you’ll need to meet specific diagnostic criteria before any doctor can write a prescription. Here’s what that process looks like step by step.
Recognize the Symptoms First
A diagnosis of low testosterone (hypogonadism) requires both confirmed low blood levels and symptoms. The symptoms that qualify you for treatment generally fall into a few categories: sexual symptoms like low libido, erectile difficulty, and reduced morning erections; physical changes like increased body fat, loss of muscle mass, fatigue, and decreased energy; and mood-related issues like irritability, difficulty concentrating, or depressed mood. You don’t need every symptom on the list, but you do need at least some alongside the blood work. A provider won’t prescribe testosterone based on lab numbers alone if you feel fine, and they shouldn’t prescribe it based on symptoms alone without confirming low levels in your blood.
Get the Right Blood Tests
The diagnostic standard is a total testosterone level below 300 ng/dL, the threshold set by the American Urological Association. The Endocrine Society uses a slightly lower cutoff of 264 ng/dL based on a CDC-harmonized reference range, but most providers work with the 300 ng/dL number as a practical benchmark. The normal range for healthy young men runs roughly 264 to 916 ng/dL.
There are strict rules about how the test must be done. Your blood needs to be drawn in the morning, ideally before 10 a.m. or within three hours of waking, because testosterone peaks early in the day and drops later. Fasting beforehand is preferred. You also need two separate tests on two different days showing consistently low levels. A single low reading isn’t enough for a diagnosis, since testosterone naturally fluctuates by 10 to 15% from day to day, and two successive measurements in the same person can differ by up to 30%.
If your total testosterone falls in a borderline range (roughly 200 to 400 ng/dL), your provider will likely also check your free testosterone, which measures the portion actually available for your body to use. Additional blood work typically includes markers like luteinizing hormone and follicle-stimulating hormone, which help determine whether the problem originates in the testes or in the brain’s signaling to them. This distinction matters because the underlying cause can change the treatment approach.
Who Can Prescribe It
Several types of doctors can diagnose and treat low testosterone. Urologists are the most common specialists for this, particularly those working in men’s health centers. Endocrinologists, who specialize in hormonal conditions, also manage testosterone therapy. Many primary care physicians handle it as well, especially straightforward cases. Specialized men’s health clinics have become increasingly popular and often streamline the process with in-house lab work and faster turnaround, though they tend to be out-of-network for insurance.
Starting with your primary care doctor is a reasonable first step. They can order the initial blood work and either manage treatment themselves or refer you to a specialist if the results are borderline or the cause is unclear.
What the Process Looks Like
The typical path from first appointment to starting therapy follows a structured sequence. At your initial consultation, the provider reviews your symptoms, medical history, and orders baseline labs. Once those results come back showing a low level, a second morning blood draw is scheduled to confirm. If both results are below 300 ng/dL and you have qualifying symptoms, the provider discusses treatment options and writes a prescription.
From your first appointment, expect the process to take two to four weeks before you actually begin therapy, depending on how quickly you can schedule appointments and how fast lab results come back. After starting treatment, you’ll have a follow-up visit with blood work around week 4, and further adjustments between weeks 8 and 12. Between 25 and 38% of men on testosterone therapy need dosing changes during this early period. Once you’re stable, ongoing monitoring shifts to every 6 months for testosterone levels and a red blood cell marker called hematocrit, with prostate-specific antigen (PSA) checked at least once a year.
Treatment Options and What They Cost
Testosterone comes in several delivery methods, each with different costs, convenience, and consistency:
- Injections are the most affordable option at roughly $30 to $150 per month. They’re given every one to two weeks, either in a clinic or self-administered at home. This is the most widely prescribed form.
- Topical gels are applied daily to the skin, typically the shoulders or upper arms. They run $200 to $500 per month, with a common starting dose of 50 mg per day. The main drawback is the risk of transferring the gel to other people through skin contact.
- Patches also deliver testosterone through the skin daily and cost $200 to $400 per month. Skin irritation at the application site is a common complaint.
- Pellets are implanted under the skin in a quick in-office procedure and release testosterone steadily over 3 to 6 months. They cost $500 to $1,500 per implantation cycle, which works out to a higher upfront cost but less day-to-day hassle.
- Oral capsules are a newer option, taken twice daily with food. They avoid the liver-toxicity concerns of older oral formulations but are typically more expensive than injections.
These prices don’t always include the cost of initial consultations, lab work, or ongoing monitoring, which can add $100 to $500 depending on the provider.
Insurance Coverage and Prior Authorization
Most insurance plans cover testosterone therapy for confirmed hypogonadism, but you’ll likely face a prior authorization requirement. Insurers typically require documentation of at least two low morning testosterone results from a lab, along with a qualifying diagnosis. Aetna’s policy, which is representative of major insurers, specifically requires two confirmed low morning testosterone levels based on reference lab ranges before approving coverage.
There are important exclusions to be aware of. Most plans will not cover testosterone for age-related decline alone (sometimes called “low T of aging” or late-onset hypogonadism), for performance enhancement, or for cognitive improvement. If your levels are low but the insurer categorizes it as normal aging rather than a medical condition, you may face a denial. Generic testosterone cypionate injections are the most likely to be covered and the least likely to trigger a coverage fight, since they’re inexpensive for the insurer. Brand-name gels and patches often require step therapy, meaning you have to try the cheaper injection first before the insurer will pay for alternatives.
Men who use specialized men’s health clinics that don’t accept insurance typically pay out of pocket for everything, including labs, consultations, and medication. Monthly all-in costs at these clinics commonly range from $150 to $300 for injection-based protocols.
What to Expect After Starting
Testosterone therapy isn’t an overnight fix. Improvements in energy and mood often begin within the first few weeks, while changes in body composition, libido, and sexual function develop more gradually over 6 to 12 weeks. Your provider will check your blood work at around 3 months after starting, measuring your testosterone level (drawn midway between injection doses if you’re using injections), hematocrit, and PSA. Hematocrit is monitored because testosterone stimulates red blood cell production, and levels that climb too high increase the risk of blood clots. PSA is tracked as a prostate safety measure.
After that initial 3-month check, the standard monitoring schedule involves safety labs every 6 months and at least an annual PSA test. Men with a family history of prostate cancer in a father or brother may need PSA checks every 6 months instead. Testosterone therapy is generally an ongoing commitment. Stopping it will cause your levels to drop back to where they were, and your body’s own testosterone production may take time to resume, or may not fully recover depending on how long you’ve been on therapy.
