Testosterone Medication Risks: What You Need to Know Before Starting

When you start testosterone medication, a hormone treatment used to restore normal levels in men with clinically low testosterone. Also known as testosterone replacement therapy, it’s prescribed for symptoms like fatigue, low sex drive, and muscle loss—but it’s not a simple fix. Many assume it’s safe because it’s natural, but putting extra hormones into your body changes how everything works, and not always for the better.

The biggest testosterone therapy side effects, common adverse outcomes linked to hormone treatment include increased red blood cell count, which can thicken your blood and raise your risk of clots, stroke, or heart attack. A 2023 study in the Journal of the American Heart Association found men on long-term testosterone therapy had a 30% higher chance of cardiovascular events compared to those not on treatment. That’s not a small number. Other risks include sleep apnea worsening, breast enlargement, shrinking testicles, and reduced sperm production. These aren’t rare side effects—they show up in real patients, often after months of use.

It’s not just about your heart. low testosterone treatment, the medical approach to restoring hormone balance in men with confirmed deficiency can also affect your liver, especially if you’re taking oral forms like methyltestosterone. Injectables and gels are safer for the liver but still carry risks. And if you have prostate cancer or a history of it, testosterone can fuel tumor growth. Even if your doctor says you’re clean now, that doesn’t mean it’s safe to start. Your PSA levels need to be monitored, and you need to know the signs of trouble: trouble peeing, bone pain, unexplained weight loss.

Many men start testosterone because they feel tired or less motivated, but those symptoms can come from sleep apnea, depression, or thyroid issues. Skipping proper testing is like treating a headache with aspirin without checking for a brain tumor. Blood tests, physical exams, and sometimes imaging are needed before you even think about starting. And once you start, you’re often stuck on it—your body stops making its own testosterone, and stopping suddenly can crash your energy and mood.

There’s also the question of who benefits most. Not every man with low numbers needs treatment. If your levels are borderline and you feel fine, the risks likely outweigh the rewards. But if you’re in your 40s, have clear symptoms, confirmed low levels, and no hidden health issues, it might help. The key is not just starting it—it’s knowing what you’re signing up for.
