recently presented study made ultrasound scans of 225 men’s penises, both flaccid and erect to see the difference between their soft and hard sizes. (Sounds like the sort of research we could really get our hands on!)The researchers then categorized each man based on whether he was a grower, a shower, or somewhere in between.Studies from around the world found that sizes have gotten about 1.2 inches longer over the last 30 years.To categorize each man correctly, the researchers came up with a specific calculation to differentiate growers from showers.
Men whose penis size increased over 56% when erect were “growers” and men whose size increased under 31% were “showers.”Researchers found that 24% of men were “growers,” 25% were “showers,” and everyone else was somewhere in between.
Unsurprisingly, men with longer flaccid penises were more likely to be “showers,” but it’s unclear whether men with shorter flaccid penises were more likely to be growers.Additionally, it’s uncertain whether the study’s findings represent the general population, since the men’s measurements were all taken from three hospitals’ urology clinics inside Madrid, Spain.
It’s also unclear whether each man’s age, weight, smoking habits, or other factors affected his flaccid and erect lengths. (Aging, weight gain, and smoking all typically reduce a man’s overall size.)But the study wasn’t conducted just to satisfy a phallic curiosity.
