The Penis Is a Check Engine Light: What ED Says About Your Heart | Dr. Tobias Kohler

Your testosterone number matters at every age, but most men never learn what theirs should be. Mayo Clinic urologist Dr. Tobias Kohler explains why ~500 is the target, why 1,000 is already running hot, what 2,000+ does to the heart, and why a randomized trial found lifting without steroids beat steroids without lifting. Plus: the blood test that catches heart risk your cholesterol panel misses.Dr. Kohler returns for his second appearance (his first, on erections, testosterone and muscle mass, is one of the most-watched episodes in the show's history). This time: why men's longevity is roughly 50 years behind women's; the Princeton IV consensus he co-chaired, which treats ED as one of the strongest predictors of a future heart attack and points young men toward a coronary calcium scan; the 0–12 ceramide blood test that changes with your behavior; how to get a testosterone baseline that actually means something; what redlining to 2,000–3,000 does to the heart, the set point and the skin; Peyronie's disease, Viagra vs. Cialis, the pills-to-implant ladder, sexual rehab after prostate surgery, and a patient who got stronger with zero testosterone.In this episode:- Why ED is a blood-flow problem "until proven otherwise," and who needs a calcium score- The ceramide test: what it measures and the score that sends you to a cardiologist- Statins, LDL goals and testosterone- Baseline T at 25, the ~500 target, why 1,000 runs hot- The 1980s trial: exercise vs. high-dose testosterone vs. both- Tolerance, the new set point, and the irreversible side effects- Trading obesity for sarcopenia in the GLP-1 era- Peyronie's disease: not cancer, not an STD- Pills, shots and implants; what 90–95% satisfaction means- Penile rehab after prostatectomyAbout Dr. Tobias KohlerTobias S.
