How Viagra was discovered and its impact

From ancient myths to modern mishaps, Michael Regilio pulls back the curtain on the rise of penis “upgrades” with firm skepticism here on Skeptical Sunday!

Welcome to Skeptical Sunday, a special edition of The Jordan Harbinger Show where Jordan and a guest break down a topic that you may have never thought about, open things up, and debunk common misconceptions. This time around, we’re joined by skeptic, comedian, and podcaster Michael Regilio!

On This Week's Skeptical Sunday:

• Erectile dysfunction has existed for centuries — once blamed on witches and “ghosts pulling cords” — but is now well understood as a mix of physical and psychological factors.
• Viagra’s accidental invention in 1998 transformed sexual medicine — turning a failed heart drug into a billion-dollar treatment that helped millions and even reduced wildlife poaching.
• Most penis enlargement methods — pills, pumps, surgeries — are ineffective or dangerous. Many cause disfigurement, infection, or permanent loss of sensation.
• Modern options like traction devices and hyaluronic acid fillers can produce modest, temporary gains — but should only be done by licensed medical professionals.
• Losing weight naturally improves blood flow, boosts confidence, and can even make the penis appear larger — proving that the safest enhancement begins with self-care and self-acceptance.
