In this episode, Dr. Morgentaler talks about how low testosterone—not high—might actually be the real risk factor for prostate cancer, challenging decades of outdated beliefs. 00:28 – Historical Beliefs and Misconceptions For decades, doctors thought testosterone fueled prostate cancer like gas on a fire—but that fear was based on outdated science. 03:27 – The Traverse Trial: Debunking Myths A massive 2023 study proved testosterone therapy doesn't raise prostate cancer risk—finally putting that old myth to rest. 06:00 – Exploring Low Testosterone as a Risk Factor Now the big question is: could low testosterone actually make prostate cancer more likely? 06:56 – Gleason Scores and Testosterone Levels Turns out, the more aggressive the cancer, the lower the testosterone levels tend to be. 11:25 – Animal Studies and Final Thoughts Even lab studies in rats and cancer cells suggest low testosterone may feed tumor growth—flipping the old story on its head.
