Questions To Ask Before Starting TRT: A Patient Guide

Before starting TRT, the questions worth asking are clinical, not cosmetic. Ask whether your low testosterone was confirmed on two separate morning blood draws, whether symptoms were documented alongside the labs, what the therapy may and may not change, how often you'll be monitored, and what may happen to fertility. The American Urological Association is direct on the first point: low testosterone should not be confirmed on a single reading (Mulhall et al., 2018). Skipping these conversations is a common source of later regret. A thorough provider welcomes every one of them, and men's hormone health starts with that exchange, not a prescription pad.

Testosterone replacement therapy is used, under the guidance of a licensed provider, to manage diagnosed hypogonadism, a medical condition in which the body may not produce enough testosterone. It is not a tune-up for normal aging. The testosterone deficiency framework matters because the US Food and Drug Administration has never approved testosterone for low levels due solely to age (FDA, 2025).

Was my low testosterone actually confirmed?

This is the question too many men never ask. The AUA recommends confirming low testosterone only after two total testosterone measurements, both drawn early in the morning, and only when those low levels appear alongside symptoms (Mulhall et al., 2018). Guidelines apply a defined low-end cutoff that a provider interprets in the context of your symptoms, not a number read in isolation. A single low reading is not enough to start therapy. Some men test low once and within range the next time. Ask which labs were run, when they were drawn, and whether your symptoms were recorded.

What form of testosterone will I use, and why that one?

Testosterone comes in several forms, and the choice is not interchangeable. Common options include intramuscular and subcutaneous injections, and transdermal gels. Each has a different absorption pattern and monitoring profile. Ask your provider why a given form fits your labs and routine, and how the dose gets adjusted. The difference between injections and topical creams is real, and it should be a conversation, not a default.

What are the actual risks?

Testosterone therapy carries documented risks, and a thorough provider will review them with you. It can raise red blood cell concentration, which is why ongoing monitoring matters. In February 2025, the FDA removed the cardiovascular boxed warning after the TRAVERSE trial but added a new warning about increased blood pressure (FDA, 2025). TRAVERSE found no rise in major cardiac events, though the testosterone group saw more pulmonary embolism, atrial fibrillation, and acute kidney injury (Lincoff et al., 2023). Other possible effects, which vary by individual, include acne and testicular shrinkage. Ask how each gets watched.

How will TRT affect my fertility?

Ask this before the first injection, not after. Exogenous testosterone can suppress the body's own signals to the testes and may reduce sperm production (Crosnoe et al., 2013). The effect varies between individuals and is not guaranteed to reverse. If you may want children, raise it now. Options such as hCG or selective estrogen receptor modulators may be appropriate, and the time to discuss hormone therapy and fertility is at the start.

What does ongoing monitoring look like?

Replacement is not set-and-forget. Plan on periodic follow-up testing and monitoring that your provider selects based on your health, including blood counts, prostate health, and blood pressure. Testosterone tends to decline gradually with age in many men (Endocrine Society, 2022), so the goal is managing a confirmed deficiency under supervision, not chasing a number. Ask how often you'll be retested and what might prompt a change to your plan.

How does telehealth access work right now?

Testosterone is a Schedule III controlled substance, so access is conditional and lawful, never automatic. Under a DEA extension effective through December 31, 2026, providers can prescribe via telemedicine without a prior in-person visit when conditions are met (DEA, 2025). A prescription still requires evaluation, lab confirmation, and a discussion of your goals and risks with a licensed provider. The most useful questions to ask before starting TRT all point the same way: confirm the lab findings, understand the plan, and treat the prescription as the result of an evaluation by a licensed provider.

FAQs

What questions should I ask before starting TRT? 

Ask whether your low testosterone was confirmed on two morning blood draws, whether symptoms were documented, which testosterone form fits you, how often you will be monitored, and how treatment may affect fertility. The AUA recommends confirming low testosterone with repeat morning measurements before therapy begins. These questions to ask before starting TRT protect you from being treated on a single, possibly misleading reading.

Do I need two testosterone tests before starting TRT? 

Yes. The American Urological Association recommends confirming low testosterone only after two separate total testosterone measurements, both drawn early in the morning, interpreted alongside your symptoms rather than from a single number. A single low result is not enough, because levels fluctuate and some men test within range on a second draw.

Does a low testosterone reading alone mean I need treatment? 

No. Guidelines require both a confirmed low level and symptoms or signs consistent with testosterone deficiency. A low number without symptoms does not by itself justify therapy. This is one of the most important questions to ask before starting TRT, because it separates a confirmed finding from a single lab value.

How will TRT affect my fertility? 

Exogenous testosterone can suppress the body's natural signals to the testes and may reduce sperm production. The effect varies between individuals and is not guaranteed to reverse. If fertility matters to you, discuss it before starting, since options such as hCG or selective estrogen receptor modulators may be appropriate.

What monitoring will I need on TRT? 

Plan on periodic follow-up testing and monitoring your provider selects based on your health, which may include blood counts, prostate health, and blood pressure. The FDA's February 2025 labeling update added a blood pressure warning for testosterone products, which is one reason ongoing monitoring is standard rather than optional.

Is testosterone approved for low levels caused by aging? 

No. The FDA has never approved testosterone for low levels due solely to aging, and the February 2025 labeling retained that limitation. Testosterone is approved to manage diagnosed hypogonadism from a medical condition, which is why an accurate evaluation comes first.
