DID YOU KNOW?
According to a 1,661 men study published in the July 10, 2013 Journal of Sexual Medicine, the average erect penis is about 5.5 (14 cm) long, ranging from 1.6 inches (4cm) long to 10.2 inches (26 cm). However, the standard deviation is about 1 inch (2.66 cm) which means that, about two-thirds of men's erect penises in the study are between roughly 4.5 and 6.5 inches long (12.5cm to 16.8cm). Another way to look at this is that almost 20% of men have an erect penis size of less than 4.5 inches, or 1 inch shorter than the average. Race is often a topic of conversation with respect to penis size but the data shows only modest variation.
