• Erections & Testosterone - Shocking Link to Muscle Mass & Men's Health | Dr Tobias S Kohler

  In this groundbreaking episode, Dr. Gabrielle Lyon sits down with Dr. Tobias Kohler, a professor of urology at the Mayo Clinic, to discuss a topic most people are afraid to talk about: men's sexual health.Dr. Kohler shares eye-opening insights, backed by over two decades of clinical experience and research, on the powerful link between foundational health habits and male sexual function. They reveal why erectile dysfunction is a critical "check engine light" for heart disease and how building muscle and exercising can improve not just your erections, but your overall longevity.This conversation goes beyond simple fixes, providing actionable, science-based information that every man needs to hear.This episode is brought to you by: Puori - Get 20% off sitewide with code DRLYON → https://puori.com/DRLYON Cozy Earth - Use code DRLYON for up to 40% off - https://cozyearth.comBONCHARGE - Use code DRLYON for 15% off your entire order - https://boncharge.com/DRLYONOneSkin - Get 15% off with the code DRLYON – https://www.oneskin.coChapters0:00 - Link between muscle mass & erections0:52 - Erectile function1:13 - The truth about penis size & penile implants2:32 - The foundational pillars of men's health8:48 - Erectile dysfunction is an early sign of heart disease16:14 - The role of anxiety, alcohol & cannabis on ED24:29 - The "use-it-or-lose-it" organ29:31 - The truth about PDE5 inhibitors (Viagra & Cialis)46:46 - The "C"s of urinary frequency54:43 - The connection between muscle, testosterone & sexual function1:02:07 - Is there a point of no return for penile health?Erections: A “Check Engine Light” for Your HealthOne of the most striking points from the discussion was Dr. Kohler’s perspective on erectile dysfunction (ED). He described it not just as a sexual problem, but as one of the earliest "check engine lights" for heart disease. The blood vessels leading to the penis are much smaller than those in the heart. As we age, plaque can build up in these vessels. This process, known as atherosclerosis, affects the smaller vessels first.This means if you're experiencing persistent issues with erections, it's a strong indicator that you may have vascular problems that could soon affect your heart. As Dr. Kohler put it, "If the penis is failing, you should assume you're going to have problems with your heart soon until proven otherwise." The good news is that anything good for your heart—like exercise and a healthy diet—is also good for your penis.The "Use-It-or-Lose-It" OrganThe conversation also tackled the surprising phenomenon of penile shortening. When the penis goes into a "garage" for an extended period—meaning there is a consistent lack of erections—it can lose length. Dr. Kohler shared that a consistent lack of erections for just three months can lead to a loss of 1-2 centimeters in length due to the formation of scar tissue. This is why he calls the penis a "use-it-or-lose-it" organ. The key to maintaining penile health is to exercise the penis through erections, and tools like a vacuum erection device can be used for penile rehabilitation.Muscle Mass, Testosterone, and Sexual FunctionFor many men, this is where the conversation gets personal. Dr. Kohler highlighted the direct correlation between muscle mass and erectile quality. Studies show that men with more muscle mass have better erections and higher testosterone levels. The reverse is also...

• Why Protein Isn’t Always Enough: Anabolic Resistance, Obesity, and Protein Efficiency | Dr. Nick Burd

  Muscle health isn’t just about how much protein you eat—it’s about how your body uses it. And for people with obesity or advancing age, that process can become less effective, even with optimal nutrition. In this episode, I am joined by Dr. Nick Burd, one of the world’s leading researchers in muscle metabolism, to unpack the concept of anabolic resistance—when muscle doesn’t respond normally to protein and/or exercise. Together, we explore how aging, obesity and even the way foods are combined on your plate can impact muscle remodeling, recovery, and growth. Dr. Burd also shares why plant-based proteins often fall short, why protein efficiency matters more than quantity, and how endurance and resistance training affect nutrient use differently.You’ll learn:What anabolic resistance is—and why it matters How to improve protein efficiency and muscle quality over timeWhy food matrix, and timing can change your resultsKey differences in nutrition strategies for endurance vs. strength athletesWhether you're focused on longevity, performance, or helping someone break through a plateau, this episode delivers the research-backed information you’ve been looking for.Who is Dr. Nick Burd? Dr. Nick A. Burd is a muscle-metabolism scientist and professor at the University of Illinois at Urbana-Champaign, where he leads the Nutrition & Exercise Performance Research Group. Originally from the Midwest, he trained under renowned experts around the world before focusing his research on how protein and exercise influence muscle health across the lifespan. His work uses advanced tracer methods and muscle biopsies to explore optimal protein intake, plant vs. animal protein quality, and strategies to combat anabolic resistance.
