People who suffer from Genital Retraction Syndrome (GRS) are overcome by the fear that their external genitals (and the breasts, for women) are shrinking and/or retracting into the body to the point of complete disappearance. GRS is a mental condition prevalent in cultures that are often without sufficient medical resources and who attribute the condition to voodoo, witchcraft, or superstition. In Asia and Africa there have been widespread instances of this syndrome called "Penis Panics."
