Koro

Koro syndrome is a psychiatric disorder characterized by anxiety and a deep fear of the shrinking of the penis and/or retraction of the genitals into the abdomen until they disappear. The sufferers believe that when the genitals do disappear they will die. It is triggered by rumors of genital disappearance supposedly caused in China by female fox spirits, in Singapore and Thailand by mass poisoning, and in Africa by sorcery, usually in the context of socio-economic or political tension.
