Can Finger Ratios Predict Penis Size?

The average penis: smaller than you think, more complex than you know. Michael Regilio gets to the meat of the matter 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:

• The penis first evolved roughly 425 million years ago as a more precise method of fertilization — allowing species to reproduce efficiently when eggs were protected inside the body.
• Humans are unique among mammals for losing the penis bone and spines, evolving instead toward smooth anatomy and longer lovemaking tied to emotional intimacy.
• Modern men experience anxiety over penis size — despite studies showing the global average is about 5.16 inches and 85% of women report satisfaction with their partner’s size.
• Pornography, camera tricks, and unrealistic media images distort expectations, fueling insecurity and demand for enhancement products that often solve imaginary problems.
• Confidence, care, and education matter more than size — regular exercise, stress reduction, hydration, and pelvic floor training (Kegels) improve both sexual health and self-esteem.
