In this episode, my guest is Dr. Michael Eisenberg, MD, a urologist and professor specializing in male sexual function and fertility at Stanford University. Based on his clinical work and research, he is considered a top world expert on male sexual and reproductive health. We discuss testosterone levels and what really impacts them, testosterone therapy, sperm quality and counts, penile and testicular health and function, pelvic floor and prostate and urinary tract health, erectile function and dysfunction and the various causes and treatments for common male sexual, hormonal and reproductive challenges. We also address post-finasteride syndrome and trends in penile length. This episode is rich in actionable information about men’s sexual and reproductive health, including key tests and at-home evaluations, and the behavioral, nutritional, exercise and prescription-based tools that can support male sexual and reproductive health.
