TRT FAQ: Testosterone Replacement Therapy Questions Answered

About Testosterone Replacement Therapy

If your energy, drive, or sense of yourself has changed and you suspect low testosterone, you are not alone in asking what comes next. Testosterone replacement therapy (TRT) is a medical treatment that brings testosterone back to a healthy range in men diagnosed with low testosterone (hypogonadism). Below are the questions we hear most often from men across Louisville and the wider Kentucky area who are weighing treatment.

Diagnosis and Eligibility

What is low testosterone?

Low testosterone, also called hypogonadism, means your body does not make enough testosterone. A diagnosis usually needs two things together: symptoms you can feel, and a blood test that confirms a low testosterone level. That test is best taken from more than one morning sample.

What are common symptoms of low testosterone?

Symptoms can include reduced sex drive, fatigue, low mood, less muscle, more body fat, and trouble concentrating. These signs are not specific to low testosterone, and many things can cause them. That is why lab testing matters before you start therapy.

How is low testosterone diagnosed?

Diagnosis usually starts with a blood test for total testosterone, drawn in the morning when levels are highest. Reference ranges depend on the assay (the testing method) and differ from one lab to the next, so your clinician reads your results against that lab’s own range alongside your symptoms. Other tests, such as free testosterone, LH, FSH, and prolactin, may be ordered to help find the cause.

Who is a candidate for TRT?

TRT is generally considered for men who have both steady symptoms and confirmed low testosterone on repeat testing. It is not right for everyone. A clinician reviews your full health history before recommending treatment.

How TRT Works

What forms does TRT come in?

Common forms include injectable testosterone, topical gels or creams, transdermal patches, and pellets placed under the skin. Each has its own dosing schedule and trade-offs, which your clinician can walk through with you.

How long does it take to feel a difference?

The answer differs from one man to the next. Some effects, such as changes in sex drive or mood, may show up within the first several weeks, while changes in body composition usually take longer. Your clinician sets expectations based on your situation.

Safety and Monitoring

What monitoring is needed during TRT?

Men on TRT are usually monitored with periodic blood tests. These may include testosterone levels, a complete blood count (to watch for a rise in red blood cell concentration), and PSA where appropriate. Your clinician sets the monitoring schedule for you.

What are the possible risks or side effects?

Possible effects can include acne, fluid retention, a higher red blood cell count, and changes in mood. TRT can also lower sperm production and affect fertility. Your clinician discusses the risks that apply to your health profile before you begin.

Does TRT affect fertility?

TRT can suppress your body’s own testosterone and sperm production, which may reduce fertility. If keeping your fertility matters to you, tell your clinician before you start, since other approaches may be discussed.

Getting Started

How do I begin?

The first step is an evaluation that looks at your symptoms, health history, and lab work. To learn more and see whether further evaluation makes sense for you, start with our health assessment. A licensed clinician reviews your information and talks through next steps with you.
