Remember when you were a kid -- or last night at the bar, whatever -- and you scrunched down a straw wrapper, dropped water on it, and watched in amazement as it grew almost four times its original length? It’s effing insane. How did that tiny little thing just up and become huge in a matter of seconds?
If this sounds extremely similar to a penis, good. It’s supposed to. We can all agree that penises are crazy: they grow, they shrink, they move on their own... seriously, your ding-dongs are like a never-ending magic show.
And speaking of show, some penises tend to do that more than others... which is why Jon Hamm is famous.
But what really determines whether you’re a grower or a shower? We decided to ask penis pros -- or urologists, in layman's terms -- Dr. Tobias Kohler and Dr. Alex Shteynshlyuger to give us the dirty on the science behind this phenomenon.
What’s the key determiner for which camp you fall into here?
Dr. Kohler: It’s genetics -- just like some people are taller and some people are shorter. There’s a genetic variation in humans like there is among all species and animals. It’s true that there is discrepancy. Some guys’ flaccid length is very similar to their erect length. And some guys’ flaccid length is dissimilar to their erect length.
Is it just genetics?
Dr. Shteynshlyuger: The difference between growers and showers is partly genetic and partly having to do with the health of the man. There are medical problems that cause erectile dysfunction such as diabetes, cardiovascular diseases, etc. But it has to do with the elasticity of the tissues and that has to do with the collagen content of the tissue. For some men the proportion of collagen is different than others. For example, in men with erectile dysfunction, studies show that there are changes to the penis in the proportion of collagen fibers, and that effects how stretchable the tissue is. Some people are born with more stretchable tissues.
