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 protective 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.
