Considering TRT? 14 Questions Men Should Ask Before Starting Testosterone Therapy

Question 1

Do I really have low T—or is something else going on?

Fatigue, low libido, reduced strength, changes in body composition, irritability, and difficulty concentrating can occur with low testosterone. They can also occur with sleep apnea, thyroid disease, depression, anemia, medication effects, inadequate sleep, obesity, and other medical conditions.

I do not diagnose low testosterone from a symptom list or online quiz. Diagnosis requires compatible symptoms and consistently low testosterone measured with reliable morning testing, generally confirmed on a separate day, interpreted with the medical history and other laboratory results.

Some men who arrive expecting testosterone leave with a different explanation. That can still be a successful visit.

Question 2

What testosterone number is actually “low”?

The American Urological Association identifies a total testosterone level below 300 ng/dL as a reasonable cutoff supporting the diagnosis of testosterone deficiency. That number is not a diagnosis by itself.

Testing should be performed in the morning and repeated. Laboratory methods and reference ranges vary. Free testosterone and sex hormone-binding globulin may add useful context in selected men, especially when total testosterone and symptoms do not align.

Question 3

Should I get tested just because I turned 40?

Not automatically. Testosterone may decline gradually with age, but age alone does not establish hypogonadism or create an indication for treatment. Testing is more appropriate when compatible symptoms are present or when the history raises concern.

Question 4

What is causing the low result?

Low testosterone can reflect a problem at the testes, reduced signaling from the pituitary or hypothalamus, or potentially reversible factors such as acute illness, substantial excess body fat, untreated sleep apnea, opioid use, heavy alcohol use, undernutrition, or previous anabolic-steroid use.

LH and FSH can help distinguish primary from secondary hypogonadism. Other testing may be appropriate when the history suggests pituitary disease, medication effects, thyroid dysfunction, elevated prolactin, or another cause.

Question 5

Will TRT fix my energy, mood, and sex drive?

In appropriately diagnosed men, testosterone therapy may improve sexual desire and activity, bone density, lean mass, and selected quality-of-life symptoms. Individual responses vary.

Testosterone is not a treatment for every form of fatigue, low mood, erectile dysfunction, or reduced athletic performance. If someone guarantees that TRT will make every man feel 25 again, that is marketing—not responsible medicine.

Question 6

Is TRT safe? What about my heart and prostate?

TRT can be appropriate and well tolerated in carefully selected patients with ongoing monitoring. It is not risk-free.

Testosterone can raise hematocrit, and a significant elevation requires clinical evaluation and may require a dose, schedule, or formulation change—or a pause in treatment. Blood pressure, cardiovascular and clotting history, sleep apnea, prostate history, urinary symptoms, and PSA may also matter.

The TRAVERSE trial found testosterone gel was noninferior to placebo for its primary major cardiovascular endpoint in a specific population of middle-aged and older men with confirmed hypogonadism and existing or elevated cardiovascular risk. In 2025, the FDA removed class-wide boxed-warning language about increased cardiovascular outcomes while requiring broader warnings about increased blood pressure.

Question 7

Will TRT affect fertility or shrink my testicles?

Exogenous testosterone can suppress LH and FSH, reduce intratesticular testosterone, decrease sperm production, and reduce testicular volume. If a man is actively trying to conceive, standard TRT is generally not the appropriate first treatment.

Depending on the diagnosis and timing of fertility goals, a physician may discuss addressing reversible causes, sperm banking, avoiding or pausing testosterone, specialist evaluation, or other medications. No medication can guarantee sperm preservation or conception.

Question 8

How is testosterone given, and which method is best?

There is no single delivery method that is best for every patient. Options include injections, topical preparations, oral testosterone undecanoate, nasal and buccal formulations, and long-acting products. Treatment selection depends on diagnosis, laboratory response, household considerations, cost, preferences, adherence, and medication-specific risks.

NovaGenix does not offer testosterone pellets or patches.

Question 9

How soon will I notice a change—and what does follow-up involve?

Response varies by symptom, formulation, dose, underlying cause, and the individual patient. No responsible clinic should promise an identical timeline or outcome for everyone.

Follow-up may include testosterone levels, CBC and hematocrit, blood pressure, treatment response, adverse effects, PSA and prostate evaluation when appropriate, and other testing based on treatment and medical history.

Question 10

Can I try lifestyle changes first?

Yes. Sometimes lifestyle changes and treatment of an underlying condition are the correct first steps. Improving sleep, treating sleep apnea, reducing substantial excess body fat, resistance training, moderating alcohol, improving nutrition, and reviewing contributing medications may improve testosterone or symptoms in selected men.

Question 11

How much does TRT cost—and what should the price include?

TRT pricing varies considerably because clinics do not all package care the same way. One advertised monthly price may cover medication only, while another may include medication, supplies, shipping, physician oversight, follow-up, or other services.

NovaGenix offers physician-directed programs that typically range from approximately $129 to $299 per month depending on the treatment plan and what is included. Pricing and inclusions should be confirmed for the individual program before enrollment because treatment needs vary.

The $125 initial male hormone panel includes physician lab review or consultation. All laboratory testing, including follow-up labs, is billed separately from the TRT program. Patients may supply their own results for review or use the clinic's physician account with Labcorp for affordable lab rates.

The important question is not simply, “What is the monthly price?” It is, “What will I actually pay for the care I am likely to need?”

Question 12

Are there hidden TRT fees I should ask about?

Ask whether the quoted price includes the prescribed medication, injection supplies when applicable, shipping, physician consultations, follow-up visits, laboratory review, and recurring administrative or membership charges. At NovaGenix, laboratory testing is billed separately. Ask whether adding another prescribed medication changes the price.

Question 13

How do I know if a TRT clinic is reputable?

Look for a real medical evaluation rather than automatic approval, appropriate laboratory testing, a clinician willing to investigate other causes of symptoms, discussion of fertility before treatment, realistic claims about benefits and risks, ongoing monitoring, and transparent pricing.

A consultation should not guarantee a testosterone prescription. A reputable clinic should be willing to tell a patient that TRT is not appropriate when the evidence points elsewhere.

Question 14

What if I change my mind or decide TRT is not right for me?

Ask about this before starting. TRT should not be treated as a casual short-term experiment because exogenous testosterone generally suppresses endogenous hormone signaling while it is being used. If treatment is discontinued, symptoms may return and recovery of natural production varies.

That does not mean every man who starts TRT is automatically committed forever. It means starting, adjusting, or stopping treatment should be discussed with the prescribing clinician rather than managed abruptly on your own.
