Koro is a culture-specific syndrome in which an individual has an overpowering belief that his or her genitals (e.g., penis or female nipples) are retracting and will disappear, despite the lack of any true longstanding changes to the genitals.

The manual gives koro's definition as "a term, probably of Malaysian origin, that refers to an episode of sudden and intense anxiety that the penis (or, in females, the vulva and nipples) will recede into the body and possibly cause death."
