If you're a man in Tampa dealing with low energy, a fading sex drive, or a general sense that you've lost a step, you've probably wondered whether your testosterone is low. It's a fair question — but the honest answer is that these symptoms are common and have many causes, and only some of them are hormonal. Here's how low testosterone actually shows up, and how we decide whether testing and treatment make sense.
Common signs men notice
Low testosterone (the medical term is hypogonadism) can contribute to a cluster of symptoms rather than one single sign. The ones men most often report include:
- Persistent fatigue and low energy, even with adequate sleep
- Reduced sex drive (libido) and, for some men, changes in erections
- Loss of muscle or difficulty building it, and an increase in body fat
- Low mood, irritability, or trouble concentrating (“brain fog”)
- Poorer sleep and reduced motivation or drive
Here's the important part: none of these symptoms is specific to testosterone. Thyroid problems, poor sleep, stress and depression, certain medications, alcohol, and simply being under-slept can all produce the same picture. That's exactly why we don't diagnose low T from symptoms alone.
How low testosterone is actually diagnosed
A proper diagnosis pairs your symptoms with bloodwork — not one without the other. Testosterone follows a daily rhythm and is highest in the morning, so the standard approach is to measure total testosterone on a morning sample, and to confirm a low result with a second morning test on a different day before making any diagnosis.1 Depending on your results, we may also check related labs (such as free testosterone and other hormones) to understand why a level is low. A single borderline number on an afternoon test is not a diagnosis.
This matters because treating a man who doesn't truly have low testosterone exposes him to risk without benefit — and because a genuinely low level sometimes points to another treatable cause worth addressing first.
Is testosterone therapy safe?
For men who have both symptoms and confirmed low levels, testosterone replacement therapy (TRT) is a well-established treatment. A large 2023 randomized trial (TRAVERSE) studied middle-aged and older men with hypogonadism and cardiovascular risk and did not find that testosterone therapy increased major cardiac events compared with placebo over the study period.2 That's reassuring, but it isn't a green light for everyone — TRT still requires screening, monitoring, and a conversation about your individual history. It isn't appropriate for men trying to conceive in the near term, and certain conditions need to be evaluated first.
When to get tested
If several of the symptoms above have been with you for a while — especially low libido alongside fatigue and mood or body-composition changes — it's reasonable to get a proper workup rather than guess. At Lavena Health, that starts with a full hormone panel and an honest conversation. If your labs and symptoms line up, we build a physician-managed testosterone therapy plan around your numbers and monitor it over time. If they don't, we tell you plainly and look at what else might be going on.
