Renew Republic

Tired, slower to recover and not feeling like yourself? Low testosterone is one possible cause, but it is not the only one. At Renew Republic in Houston, every testosterone conversation starts with data, not guesswork. This guide walks through what low testosterone is, how it is properly diagnosed, what treatment involves and how to decide whether it is right for you.

Key Takeaways

• Low testosterone should be confirmed with lab work, not symptoms alone. The American Urological Association (AUA) recommends two early morning total testosterone tests on separate days.
• The AUA uses 300 ng/dL as a reasonable cut-off for low total testosterone.
• The large TRAVERSE trial (NEJM, 2023) found testosterone therapy did not increase major cardiovascular events compared with placebo in men with confirmed low testosterone, under careful medical monitoring.
• Therapy is not for everyone. It can affect fertility and requires ongoing lab monitoring.
• Your first step at Renew Republic is a complimentary private consultation with our medical team.

What Is Low Testosterone?

Testosterone deficiency (sometimes called low T or hypogonadism) means the body is not producing enough testosterone to support normal function. Testosterone plays a role in energy, mood, libido, muscle mass, bone density and red blood cell production. Levels tend to decline gradually with age, and other factors such as sleep, body weight, stress and certain medications can also affect them.

Common Signs Men Notice

• Low energy or persistent fatigue
• Reduced sex drive
• Loss of muscle mass or strength
• Increased body fat
• Low mood, irritability or poor concentration

These symptoms are real, but they are also nonspecific. Thyroid issues, poor sleep, sleep apnea, stress and other conditions can look very similar. That is exactly why proper testing matters before anyone talks about treatment.

How Low Testosterone Is Diagnosed

According to the AUA testosterone deficiency guideline, the diagnosis should be made only after two total testosterone measurements taken on separate occasions, both drawn in the early morning. The AUA uses a total testosterone level below 300 ng/dL as a reasonable cut-off, considered together with symptoms.

A thorough evaluation usually looks beyond a single number. Your provider may review other markers and your full health history to understand the cause and to make sure therapy is appropriate and safe for you.

What the Research Says About Safety

For years, men heard conflicting messages about testosterone and heart health. The FDA-requested TRAVERSE trial, published in the New England Journal of Medicine in 2023, enrolled more than 5,200 men aged 45 to 80 with confirmed low testosterone and existing or high cardiovascular risk. Testosterone therapy was noninferior to placebo for major adverse cardiac events.

The same trial also found higher rates of atrial fibrillation, acute kidney injury and blood clots in the lungs in the testosterone group. The investigators stressed that the reassuring findings apply to men with properly confirmed low testosterone who are carefully monitored. That is the standard we hold ourselves to.

Who Should Be Cautious

• Men trying to have children. Testosterone therapy can suppress sperm production. The AUA advises against it for men who are currently trying to conceive.
• Men with a history of blood clots. Current guidance calls for caution in men with prior thromboembolic events.
• Men without confirmed low levels. Treating normal testosterone levels is not recommended.

Your provider will review your history, goals and lab results with you before making any recommendation.

How It Works at Renew Republic

1. Complimentary consultation. A private conversation with our medical team about your symptoms, history and goals.
2. Lab work. We look at your biomarkers so decisions are based on data.
3. Personalized plan. If therapy is appropriate, your provider builds a medically guided plan around you. If it is not, we will tell you that too.
4. Ongoing monitoring. Follow-up labs and check-ins keep your plan safe and on track.

Testosterone is one part of a bigger picture. Many members also ask about IV therapy, peptide therapy, NAD+ and aesthetics, and sleep, nutrition and training still matter. Individual results vary, and no treatment replaces the fundamentals.

Frequently Asked Questions

What testosterone level is considered low?

The AUA uses a total testosterone level below 300 ng/dL as a reasonable cut-off, confirmed on two separate early morning tests and considered alongside symptoms.

Do I need lab work before starting TRT?

Yes. Guidelines call for confirmed lab results before diagnosis, and ongoing labs are part of safe treatment. At Renew Republic, every plan starts with data.

Is testosterone therapy safe for my heart?

The 2023 TRAVERSE trial found no increase in major cardiovascular events versus placebo in monitored men with confirmed low testosterone, though some other side effects were more common. Your provider will review your personal risk with you.

Will TRT affect my fertility?

It can. Testosterone therapy can suppress sperm production, so tell your provider if you are trying to conceive or plan to in the future.
