Chapter One

Men with big feet have bigger penises

Have you ever noticed a man with particularly big feet and wondered if other parts of him were just as large? While some claim that a man's penis size can be predicted by the size of his feet, others say that it's the size of his hands or even his nose that really gives away the secret of what's in his pants. This idea of comparing body parts to estimate hidden assets may have originated with discriminating shoppers, but it may also have its roots in real science. The Hox gene in mammals plays a role in the development of the toes and fingers, as well as the penis or clitoris. Given how rarely one hears "gene expression" mentioned along with the talk of penises and feet, it seems much more likely that this myth springs from our desire, as humans, to identify patterns—even when the pattern is not really there. We like to have explanations for things we see, and we like to group like things with like things (in this case, appendages on men).

Despite the similar genetic controls for these protuberances, men with big feet do not necessarily have bigger penises. While at first, the prospects for estimating penile length with a quick glance at a man's feet seemed promising, science now shows us that this is not the case. A study of sixty men in Canada suggested that there was a weak—but statistically significant—relationship between penile length and both body height and foot length (remember—statistically significant doesn't necessarily mean significant in real life). However, a larger study of 104 men, done by two urologists, Drs. Shah and Christopher, which measured penises when pulled to their longest lengths, found that shoe size and penis size were not correlated with one another. An even larger study called the "Definitive Penis Size Survey," which looked at 3,100 men, also found no relationship between shoe size and erect penis size. This was even when men reported their size, as opposed to direct measurement. And when men are asked to report the length of their own members . . . well, let's just say that science also shows us that exaggeration routinely comes into play. Furthermore, the "Definitive Penis Size Survey" was never peer-reviewed or published in a scientific journal. We trust the results from Drs. Shah and Christopher the most, but this survey backs them up. Studies also show no link between finger length and penis size. You can look at a guy's feet or hands all you want, but they won't tell you anything else about how he measures up.

    Entertaining and Educational

    This is an easy-to-read book which busts medical myths that I previously thought unshakeable. I was truly surprised at many of the "facts" that were proven to be otherwise. The book gives background in many cases and debunks each myth in an easy-to-understand manner with a mix of light humor. It makes this book as entertaining as it is informative.
