Erectile Dysfunction Prevalence and Brain Mechanisms

Most men don't know they have a pelvic floor, and most doctors aren't trained to look for dysfunction in it. The result: testicles are being surgically removed for pain that's actually neuropathic, at double the rate of a far more effective nerve-sparing procedure.

In this episode, Dr. Gabrielle Lyon sits down with Dr. Susan Macdonald, a board-certified urologist, surgical program director at Penn State, and one of only ~30 U.S. specialists treating chronic pelvic pain in men, to discuss:

• Why "prostatitis" is often the wrong diagnosis, and how rounds of antibiotics mask the real problem
• The male pelvic floor anatomy almost no medical school teaches, and how to recognize dysfunction in yourself or a patient
• Off-label medications (Cymbalta, gabapentin, amitriptyline) that are quietly transforming chronic pelvic pain treatment
• Why erectile dysfunction is rising sharply in teenagers, and the role pornography plays in rewiring young brains
• Who actually qualifies for a penile implant, and what the surgery really involves

If you've been told your pain is "all in your head," or you're a clinician seeing patients fall through the cracks, this conversation gives you the framework, the language, and the next steps to find real answers.
