Penis‐root perception of Koro patients

Koro is an acute anxiety reaction in which the perception of decreased penis length because of intra-abdominal traction is the main feature. This study attempts to explore the penis-root perception of the Koro patients by a graphomotor projective test--the Draw-a-penis Test (DAPT). This controlled DAPT investigation shows that Koro patients perceived the penis as a detached organ with root-boundary definiteness as evidenced from their close penis-root perception. They also displayed reduced volumetric perception of penis-root than the normal subjects. These perceptual deviations in penis-root image are discussed in relation to their Koro vulnerability.
