 In most of the non-Chinese cases in the Western hemisphere, genital shrinkage is reported but not all the other typical koro symptoms, such as fear of death, as in endemic countries.The incomplete forms of koro are regarded as the non-cultural forms, while the complete form with acute anxiety is the classical culture-bound type.Local official records indicate genital retraction epidemics in Hainan Island and Leizhou Peninsula in Guangdong, China, as early as the late 19th century.
