It is a real psychological disorder called koro in which victims (mostly men, but sometimes women) come to believe that their genitals are shrinking or retracting into the body. The concern is not only for their sexuality, but also for their lives, since they believe that the condition may be life threatening if not reversed. In order to prevent further shrinkage, victims have been known to securely tie their penises with string or metal clamps — even sometimes having family members hold it in relays until treatment can be sought, usually from shamen or traditional healers.
