Testosterone levels in 40-year-old men are 30 percent lower than their fathers, and most doctors still have no idea what to do about it.

Host Dave Asprey sits down with Dr. Justin Houman, a nationally recognized urologist and Assistant Professor of Urology at Cedars-Sinai Medical Center. Fellowship-trained and specializing in men's health, male fertility, and sexual medicine, Dr. Houman combines cutting-edge medical advancements with holistic lifestyle strategies to help men optimize testosterone, sexual health, and reproductive performance at every age.

Together, Dave and Dr. Houman tear through the myths, the bad science, and the outdated medical dogma around testosterone, erectile function, fertility, and male sexual health. They cover everything from why testosterone levels have collapsed in a single generation, to the real story behind the FDA black box warning, to practical protocols for men who want to optimize without sacrificing fertility. This is the masterclass on men's health that no one else is having on record.

This is essential listening for anyone serious about biohacking, longevity, human performance, hormone optimization, brain optimization, anti-aging, functional medicine, mitochondria, and Smarter Not Harder approaches to male health.
