Koro, a culture-specific disorder consisting of complaints of genital
retraction and fear of death associated with genital retraction, has been
recognized in Asian cultures in single cases and in epidemic proportions.
Koro has been described in non-Asian patients as well, leading to debate
concerning the true nature of the syndrome. The authors review past
attempts to define and classify koro and present a classification for
DSM-IV that they believe could be used to classify other culture-bound
syndromes as well.
