Symptoms of Low Testosterone and When to Test

Low testosterone can look like low energy, reduced libido, erectile changes, more body fat, weaker exercise recovery, and brain fog. These overlap with other conditions, so labs are essential.

A good self check

• Symptoms have persisted for a few months, not a rough week.
• Low sex drive or erectile changes are present alongside fatigue or mood shifts.
• You can do early morning blood draws on two different days.

Most clinicians diagnose only when symptoms are present and levels are consistently low. Guideline summaries from the Endocrine Society and the American Urological Association explain these principles in detail.

If erectile symptoms are front and center, skim the clinic’s page on erectile dysfunction to understand how sexual health and cardiovascular risk fit into the workup.

‍

How Diagnosis Works in Plain Language

What your clinician will do

1. Review symptoms and history, including sleep, fertility plans, medications, and supplement use.
2. Order early morning total testosterone, then repeat on a different morning to confirm.
3. If low is confirmed, order related labs, for example LH, SHBG, and prolactin, to understand the cause and a safe plan.

Key thresholds and principles

• The AUA supports using a total testosterone level below about 300 ng/dL as a reasonable cutoff when paired with compatible symptoms, with two early morning tests on separate days. See the AUA guideline for context.
• The Endocrine Society emphasizes symptoms plus unequivocally low levels before diagnosing hypogonadism. Their summary is here, in the Endocrine Society resource.

If prostate history is part of your story, the clinic’s page on prostate health explains common screening discussions you can expect during a visit.

Your Testing Workflow in Greater Phoenix

Step by step

1. Book an early morning lab appointment, then plan a second morning draw if the first result is low.
2. Follow prep instructions from your clinician, including guidance on fasting and medications.
3. Review related labs to understand cause and safety, not just the testosterone number.

Lab quality matters

• The CMS CLIA program regulates clinical labs nationwide to safeguard accuracy. If you are curious, read the CMS overview of CLIA standards.
• Arizona’s health department provides local CLIA information that clinics use to stay compliant. See the ADHS page on CLIA in Arizona.

If you prefer to keep everything under one roof, you can ask about coordinating draws through the clinic’s lab testing page, then send questions through the contact form.

Mini checklist for your appointment

• Bring any prior labs and a symptom timeline.
• List current medications and supplements.
• Note sleep, weight, and exercise changes over the last 3 to 6 months.
• Decide whether near term fertility matters, since that changes the plan.
• Prepare questions about method, follow up cadence, costs, and insurance.

TRT Options Explained, Pros and Cons

Your clinician matches the method to goals, lifestyle, and medical history. All options require periodic monitoring.

Common methods in the United States

• Injections, such as cypionate or enanthate. Pros, predictable absorption and flexible dosing. Cons, needle use plus peaks and troughs.
• Topical gels. Pros, easy to apply. Cons, daily adherence and transfer risk without careful handwashing and skin coverage.
• Patches. Pros, steady delivery. Cons, possible skin irritation.
• Pellets. Pros, long dosing intervals. Cons, a minor procedure and less flexibility.
• Nasal gel. Pros, no skin transfer concern. Cons, multiple daily doses.

For a quick primer that aligns with how the clinic approaches care, review the internal page on testosterone treatment, then bring your questions to an appointment.

Shared decision prompts

• How often will dose adjustments be considered.
• Which labs will be checked and when.
• Any comorbidities that nudge the choice, for example high hematocrit or skin concerns.
• How ED symptoms and prostate health will be monitored alongside TRT, with context from the clinic’s pages on erectile dysfunction and prostate health.

Guideline snapshots that help you read your plan, the Endocrine Society’s summary and the AUA guideline.

Safety and Monitoring Basics

Safety is about choosing the right patient, then monitoring. In February 2025, the FDA issued class wide labeling changes across testosterone products. Labels now include a warning about increased blood pressure for some formulations, retain the limitation of use for age related low testosterone, and add results from a large cardiovascular outcomes trial that did not show increased major adverse cardiovascular events in men with true hypogonadism. You can read the summary on the FDA’s update page.

Monitoring checklist your clinician may use

• Recheck symptoms and side effects at defined intervals.
• Repeat labs to track testosterone level and hematocrit, and add other markers as indicated.
• Discuss PSA testing and prostate considerations by age and risk, informed by your prostate health conversation.
• Watch blood pressure, especially during initiation or dose changes.
• Review sleep apnea symptoms, weight, and mood, since these influence outcomes.

Cost and Pricing Guide for Phoenix

Costs vary by method and monitoring plan. A simple way to think about it is by components.

What usually appears on a bill

• First visit and evaluation. History, exam, and a shared decision plan.
• Baseline labs and a confirmatory early morning repeat. If you want to preview how in clinic labs are handled, the clinic explains this on its page about lab testing.
• Medication and supplies. Injections, gels, patches, pellets, or nasal gel.
• Follow up visits and monitoring labs.

What changes the total

• Method choice. Injections are usually less expensive per month than pellets or branded gels.
• Visit cadence. New starts often have closer follow up.
• Insurance details. Some plans cover evaluation and labs, others treat therapy as a cash pay item. Health savings accounts can help with qualified expenses.

Ways to get a clear estimate

• Ask for a written outline of expected visits and labs for the first year.
• Request ranges by method. Then compare those to your preferences about dosing frequency and convenience.
• If you are deciding between methods, skim the clinic’s overview of testosterone treatment to align costs with lifestyle. Then send any questions through the contact form.

How TRT Connects to Weight, Sleep, and Mood

Testosterone is one piece of a wider health picture. Weight, sleep, alcohol, and training load all affect symptoms and lab values.

Practical pointers

• Sleep first. Poor sleep can lower testosterone, reduce libido, and worsen recovery. Improving sleep often improves daytime energy regardless of therapy.
• Train smart. Overreaching without recovery can flatten progress, even if labs improve.
• Pair with weight care. If weight is a driver, combine therapy with a structured plan for nutrition and movement. The clinic’s page on medical weight loss explains how supervised programs manage labs and vitals during treatment.

‍

ED and Prostate Health with TRT

Erectile symptoms and prostate history are part of safe care.

What to expect in clinic

• A conversation about sexual function, vascular risk, and medications.
• A prostate health discussion matched to your age and risk. National guidance supports shared decision making about PSA screening for many men in midlife, with a different approach for older adults. You can read the current statement on the USPSTF prostate cancer screening page.
• If ED is your top concern, you can review the clinic’s page on erectile dysfunction, then raise specific questions at your visit.

A note on cardiovascular safety

Large, modern trials such as TRAVERSE found no increase in major adverse cardiovascular events in men with confirmed hypogonadism who were treated and monitored, though some adverse events were more frequent and must be watched. For a primary source, see the trial in the New England Journal of Medicine. The FDA has also issued class wide label updates that include blood pressure warnings for certain products, which clinicians follow during monitoring. You can read the summary on the FDA’s update page.

FAQ

• How long does TRT usually take to help with energy and libido?
  Many men report initial changes within several weeks, with fuller effects after dose titration and monitoring over a few months. Plans are individualized and include follow up labs.
• Do I need therapy for life?
  Some causes are reversible, others are not. Your clinician will review root causes and will taper or pause therapy if things change.
• Can I start without two morning tests?
  Best practice is two early morning total testosterone measurements plus symptoms before starting. This aligns with national guideline principles. See the Endocrine Society guidance.
• Is testosterone safe if I have heart disease?
  Care teams follow evidence from large trials and FDA labeling, then monitor closely. You can read the TRAVERSE trial in the New England Journal of Medicine and the FDA’s 2025 safety update.
• Will therapy affect fertility?
  Exogenous testosterone can suppress sperm production. Tell your clinician if near term fertility matters so that alternatives can be discussed.
• How often are labs once I start?
  Expect a scheduled cadence early on, then a stable rhythm once you are dialed in. The clinic outlines how labs fit into care on its page about on site testing.
• What if my main concern is ED?
  It is common to address ED and hormones together. You can preview the clinic’s approach on its page about erectile dysfunction, then bring questions to your visit.‍
• How do I get a cost estimate?
