"Koro" (genital retraction syndrome): psychotherapeutic interventions.

"Koro" is a belief or delusion of retraction of the penis into the abdomen. Originally thought to be a Chinese and Indonesian culture-bound syndrome, it has recently been noted to occur in "Western" patients. Two Western patients with this syndrome are described and their psychotherapeutic treatment and outcome outlined. A stepwise approach to the treatment of the Koro symptom is suggested.
