Testosterone replacement therapy (TRT) often sparks a mix of interest and hesitation, especially when it comes to heart health. For men navigating andropause symptoms like fatigue or decreased libido, the thought of hormone therapy can bring both hope and concern.
At Dr. Chow’s Rejuvenation Practice in Lee’s Summit, our approach to male hormone therapy is physician-led, lab-guided, and rooted in evidence-based care. This guide will clarify the most frequent questions we hear, by separating longstanding myths from clinical facts, so patients can make informed decisions about their long-term health.
Does Testosterone Therapy Increase the Risk of Heart Attack or Stroke?
Myth: Testosterone therapy causes heart attacks or strokes in men over 40.
Fact: There is no credible evidence that testosterone therapy increases the risk of heart attack or stroke in medically eligible men. The most definitive data comes from the TRAVERSE trial, published in the New England Journal of Medicine in 2023. This large, multi-center, placebo-controlled study followed over 5,200 men between the ages of 45 and 80. Most had pre-existing cardiovascular risk factors such as high blood pressure, high cholesterol, or type 2 diabetes.
The study found no increase in the rate of major adverse cardiac events, including heart attacks or strokes, in the group receiving testosterone therapy compared to placebo. The reported hazard ratio was 0.96, confirming non-inferiority in cardiovascular safety.
The takeaway: when prescribed under proper medical supervision and supported by lab testing, TRT does not raise the risk of cardiovascular events in men with low testosterone.
Are Testosterone Injections More Dangerous Than Gels or Patches?
Myth: Testosterone injections are riskier because they cause hormone spikes.
Fact: Each TRT method delivers testosterone differently, but none is proven to be more harmful than another when managed appropriately. Injections can produce sharper fluctuations in serum testosterone, which is why some men may experience mood swings or symptoms between doses. However, there is no established link between injection-based TRT and increased heart attack risk.
Transdermal methods such as gels or patches release testosterone more steadily, resulting in more gradual absorption and potentially fewer fluctuations. Still, these options also require regular monitoring to ensure testosterone levels remain within a therapeutic range.
Ultimately, the delivery method should be selected based on individual health status, lifestyle, and adherence preferences, not perceived safety differences.
| Method | Absorption | Risk Factor | Monitoring Needs |
| Injections | Sharp peak/trough | Higher hematocrit risk | Hematocrit, blood pressure |
| Gels | Steady levels | Lower fluctuation | Daily consistency |
| Patches | Steady levels | Mild skin irritation (rare) | Skin tolerance, serum levels |
Can TRT Cause Atrial Fibrillation or Blood Clots?
Myth: Testosterone therapy leads to dangerous heart rhythms and blood clots.
Fact: While the TRAVERSE trial did observe a slight increase in the incidence of atrial fibrillation and pulmonary embolism, these events were rare. The overall rate of atrial fibrillation in the TRT group was under 1%, and these events occurred most often in men with existing cardiovascular disease or high hematocrit levels.
This is why a proper medical evaluation is essential. At Dr. Chow’s Rejuvenation Practice, every patient undergoes hematocrit screening, PSA testing, and cardiovascular risk evaluation before beginning hormone therapy. Throughout treatment, lab values are routinely monitored to catch changes early and guide safe dosing.
Monitoring Example:
- Elevated hematocrit → Increases clotting risk
- Risk can be prevented by adjusting dosage or pausing therapy temporarily
Is TRT Unsafe for Men Over 50?
Myth: Testosterone therapy is not safe for older men.
Fact: Chronological age alone is not a disqualifying factor for TRT. In fact, most participants in the TRAVERSE trial were men over 60. The data confirmed that testosterone therapy did not raise cardiovascular risk even in this older population.
What determines safety is comprehensive health screening, including cardiovascular history, metabolic markers, and prostate health, not age. At Dr. Chow’s Rejuvenation Practice, men over 50 receive an in-depth evaluation to ensure that any therapy introduced supports, not compromises, their long-term health.
Screening typically includes:
- Blood pressure
- Cholesterol panel
- High-sensitivity C-reactive protein
- PSA and liver function
Is Natural Testosterone Always Safer Than Medical TRT?
Myth: Lifestyle changes are safer and more effective than testosterone therapy.
Fact: Lifestyle factors such as resistance training, stress reduction, quality sleep, and nutrition can support testosterone production. These are important habits for every man, regardless of hormone status. However, for men with clinically diagnosed hypogonadism (defined as total testosterone levels below 300 ng/dL with associated symptoms), lifestyle adjustments alone may not be enough to restore hormone balance.
Medical testosterone replacement is designed to bring levels back into a healthy physiological range, not to enhance or overcorrect. It is appropriate for men who have been properly evaluated and have a documented deficiency.
Natural interventions are a helpful preventative strategy, while TRT is a corrective treatment. At Dr. Chow’s clinic, both paths are supported and often work in synergy.
Can I Start TRT Without Bloodwork?
Myth: Men can self-diagnose low testosterone and begin therapy with over-the-counter supplements or online prescriptions.
Fact: Testosterone therapy is a medical treatment that should only begin after lab confirmation and clinical consultation. Best practice guidelines recommend two early-morning testosterone tests, evaluated alongside a comprehensive symptom review.
Additional tests, such as PSA (for prostate health), hematocrit (for clotting risk), and liver function, are also necessary. TRT should not be initiated without this data, especially in men with cardiovascular risk factors.
At Dr. Chow’s Rejuvenation Practice, hormone therapy is approached with the same level of caution and clinical oversight as any other medical intervention. Bloodwork is not optional; it is foundational to safe and effective care.
How Dr. Chow Approaches Testosterone Therapy
At Dr. Chow’s Rejuvenation Practice, testosterone therapy is not offered in isolation. Every treatment plan begins with a complete medical assessment and is supervised by a board-certified physician with more than two decades of experience in clinical medicine and aesthetic wellness.
This approach emphasizes:
- Comprehensive lab testing and cardiovascular screening
- Nutritional and lifestyle guidance to support metabolic health
- Ongoing evaluation of sleep, energy, libido, and mental clarity
- Integration with related concerns such as sexual wellness, body composition, and fatigue
Rather than addressing testosterone in a vacuum, the clinic focuses on the broader picture, how hormonal balance affects long-term wellness, vitality, and function.
This is not a template-based protocol. Every patient receives individualized care, monitored through lab metrics, symptom feedback, and follow-up consultations.
Heart Health Starts With Smart Supervision
Testosterone therapy has evolved significantly over the past decade. Today, it is considered safe for men with clinically low testosterone when prescribed and monitored by a qualified medical provider.
At Dr. Chow’s Rejuvenation Practice, hormone optimization is never about shortcuts. It’s about restoring balance, improving function, and supporting long-term wellness through science, supervision, and support.
If you’ve experienced symptoms like chronic fatigue, low drive, or mental fog, you deserve clarity, not assumptions. Hormone testing and cardiovascular screening can offer that clarity, and from there, thoughtful treatment options may follow.
