Can Testosterone Give Your Heart a Hard Time? Let's Set the Record Straight

You've likely heard the whispers: "Testosterone gives you bulging muscles and supercharged prowess, but beware – it's a heart stopper." But does this claim hold water? Let's unravel the truth from the myths.


Not too long ago, the FDA got a tad twitchy about testosterone, all thanks to one dubious study that landed in the PLOS One journal. This study dove into a colossal healthcare database to dissect the effects of testosterone replacement therapy (TRT) over a 90-day period. It raised eyebrows by suggesting that younger men with a heart disease history who hopped on the TRT train faced a two to three-fold spike in the risk of heart attacks. For the older gents above 65, the risk doubled, regardless of their past heart history.

But hold your horses, because this study came with its own baggage:

It never bothered to check the testosterone levels before or after treatment. We're left scratching our heads, wondering if these men even had low testosterone in the first place or if they were drowning in overdoses.

It conveniently forgot to keep tabs on estrogen and red blood cell levels. If left unattended, high estrogen and elevated red blood cell counts could be like a ninja sneak attack on your ticker.

The control group in this study was on medication designed to fend off heart attacks. Comparing them to the testosterone group was like pitting a knight in shining armor against a fluffy bunny.

So, it's time to toss that study into the river – preferably one with a bit of rage.


Right before that scandalous study surfaced, The Journal of the American Heart Association unleashed a meta-study that made a big pot of sense by merging data from over 100 testosterone studies and their impact on heart health. And the verdict was crystal clear: your ticker needs a good dose of testosterone.

In fact, the journal sounded the alarm bell on low T, linking it to a higher mortality rate across the board, and waving flags for more cardiovascular casualties, obesity, and diabetes.

The list of health issues that hold hands with low testosterone is hair-raising:

  • A hike in the risk of heart problems
  • Arteries that get skinnier than a supermodel on a juice cleanse
  • EKG readings that look like someone playing hopscotch
  • Congestive heart failure that pops up like an unwanted party guest
  • More angina than you'd ever want
  • Piling on those extra pounds
  • The unwelcome embrace of Type II diabetes
  • The metabolic syndrome tagalong
  • An annoying resistance to insulin
  • A spare tire that just won't deflate
  • Higher chances of punching your ticket for the great beyond, including the heart-shaped express route

So, when it boils down to the facts, you have one black sheep of a study painting testosterone as the villain. But in the opposite corner, you've got at least a century of research showing that low testosterone levels are like a one-way ticket to Healthville's underbelly.


For an extra layer of comfort, let's dish out one more study. Three years ago, the researchers at the Intermountain Medical Center Heart Institute assembled a posse of 755 heart patients, aged 58 to 78, all with a testosterone deficiency.

These folks were divided into three camps: two received testosterone replacement therapy in the form of gels or shots, while one gang played the role of the placebo.

Fast forward one year:

  • 64 out-of-luck souls not on testosterone therapy met their arch-nemesis – major cardiovascular events (think strokes, heart attacks, or the end of the line).
  • Just a mere dozen of the medium-dose testosterone crowd faced such events.
  • And a grand total of nine high-dose testosterone troopers took a similar hit.

In simple terms, those who didn't embrace the testosterone were 80% more likely to cross paths with misfortune. The same tune played on three years later, with 125 untreated warriors experiencing heart troubles compared to 38 from the medium-dose squad and only 22 from the high-dose regiment.

So, here's the real scoop: maintaining normal or slightly higher than normal testosterone levels is like sending love letters to your heart. So, the next time you overhear someone maligning testosterone, remind them that the evidence tells a far more interesting story.
