What Monitoring May Be Discussed During Testosterone Treatment?

If you and your clinician decide that testosterone treatment makes sense for you, the decision does not end with a prescription. Treatment comes with regular follow-up, because testosterone affects more than one part of the body. This guide explains the kinds of monitoring that may be discussed and why they matter. Your own plan will depend on your health and on Dr. Ewals's judgment.

Why Monitoring Matters

Monitoring helps answer three questions. Is the treatment doing what it is meant to do? Is it causing side effects you might not notice on your own? And is it still the right choice for you? Both the American Urological Association (AUA) and the Endocrine Society include follow-up in their guidance on testosterone treatment. Guidelines describe check-ins in the first months after starting and then at regular intervals.

Before You Start: Baseline Tests

Monitoring starts before the first dose. Baseline tests give a reference point to compare against later. According to the AUA guideline, these include:

• Hemoglobin and hematocrit, which measure red blood cells.
• PSA (prostate-specific antigen) for men over 40, to check for signs of prostate cancer before treatment.

Your clinician may also ask about sleep, snoring, fertility plans, heart health, and urinary symptoms before starting.

What May Be Checked During Treatment

Testosterone Levels

Follow-up blood tests show whether your level is in the intended range. When the blood is drawn can matter, depending on the form of testosterone you use, so follow your clinician's timing instructions.

Hematocrit

Testosterone can raise red blood cell counts. This is called erythrocytosis. A high hematocrit can make the blood thicker, so it is watched with regular blood tests. If it rises, the clinician may change the dose or plan.

PSA and Prostate Health

For many men, especially over 40, PSA may be rechecked during treatment, and the clinician may ask about urinary symptoms. The Endocrine Society guideline describes when a change in PSA should lead to a urology referral.

Blood Pressure and General Health

Blood pressure and overall heart health are part of routine check-ins.

Symptoms to Report Between Visits

Some changes are easier for you to notice than for a lab test. Tell the clinic if you notice:

• New or louder snoring, gasping at night, or more daytime sleepiness. Testosterone may worsen untreated sleep apnea.
• Swelling in your ankles or legs, which can be a sign of fluid retention.
• New acne or oily skin.
• Breast tenderness or swelling.
• Changes in mood, irritability, or sleep.
• Trouble urinating or changes in urine flow.
• Skin irritation where you apply a gel or patch.

If you have chest pain, trouble breathing, weakness on one side, or sudden leg swelling with pain, get emergency care right away.

If you use a testosterone gel, ask about how to avoid passing it to others through skin contact, especially children and women. FDA labeling for gels includes a warning about this.

Fertility

Testosterone treatment can lower sperm production. If you might want children now or in the future, bring it up before starting and at follow-up visits. Your clinician can talk with you about options, which may include other medicines or a referral.

Stopping or Changing Treatment

Don't stop or change your dose on your own. If you want to stop, talk with your clinician about what to expect and how your body's own production may respond. Monitoring may continue for a while after stopping.
