Before we begin: A testosterone level is only one piece of your health story. Persistent symptoms deserve real medical evaluation, not a guess or a supplement ad.
Myth: TRT always causes heart attacks
The TRAVERSE trial found similar rates of major cardiovascular events for testosterone gel and placebo in a specific high-risk population with confirmed low testosterone. The study does not mean all forms, doses, and patient groups have identical safety. Blood-pressure increases remain a real issue, and clinical screening matters.
Myth: TRT is proven to cause prostate cancer
Current evidence has not established that properly prescribed TRT causes prostate cancer, but long-term cancer safety remains uncertain. Prostate screening and monitoring should be individualized. Known or suspected prostate cancer requires specialist assessment, and some situations are contraindications to treatment.
Fact: red blood cells can climb
TRT can increase hemoglobin and hematocrit. Excessive increases require attention because thickened blood is not harmless. Your clinician may adjust the dose, investigate other causes, change formulations, or stop treatment. This is one reason labs matter before and during treatment.
Fact: TRT can affect sleep and skin
Acne, oily skin, swelling, and breast tenderness are possible. Severe untreated sleep apnea is a reason not to start TRT under major endocrine guidance. Speak up if you experience new symptoms during treatment.
Fact: the medication can affect fertility
TRT suppresses sperm production. This is not a tiny footnote. If you may want children, discuss fertility before treatment and do not assume you can undo suppression overnight.
Myth: more testosterone is always better
Trying to push levels above a physiologic range has no established general health benefit and can increase harm, especially with anabolic steroid misuse. The goal of therapy is appropriate replacement and symptom improvement—not bragging rights at the gym.
Important reasons to pause and investigate
A clinician should carefully evaluate men with untreated severe sleep apnea, elevated hematocrit, certain prostate or breast conditions, recent major cardiovascular events, uncontrolled heart failure, thrombophilia, or active fertility goals. Details and contraindications depend on current guidelines and individual circumstances.
The takeaway
Safe testosterone care means accurate diagnosis, informed choice, and follow-up—not automatic prescriptions, alarmist myths, or secret “hormone hacks.”
