Glans penis perception of Koro patients.

Koro is a form of sexual neurosis in which a reaction of acute anxiety accompanies the perception of decreased penis length from intra-abdominal traction. This study attempts to explore the glans penis perception of Koro patients by a grapho-motor projective test--DAPT (Draw-a-penis Test). This controlled DAPT investigation shows that Koro patients have significantly less perception of glans penis than the controls. This perceptual deviation in glans penis image is discussed in relation to the sexual-behavioral profile and Koro vulnerability of the patients.
