In the human penis, the prepuce is known to have ten times more corpuscular sensory receptors than the glans penis.
Most people are surprised to learn that the glans penis is one of the least sensitive parts of the entire body.<ref>Halata Z, Munger BL.

The glans is insensitive to light touch, heat, cold, and even pinpricks, as researches at the Department of Pathology in the Health Science Centre at the University of Manitoba discovered<ref>Taylor JR, Lockwood AP, Taylor AJ.
