Koro syndrome is a psychological condition characterized by an intense fear that one's genitals are retracting into the body, leading to the belief that they may disappear. This syndrome is often associated with anxiety and can cause significant distress for those affected. It is most commonly reported in certain cultures, particularly in parts of Southeast Asia. The exact cause of Koro is not well understood, but it may be linked to cultural beliefs, stress, or mental health disorders. Treatment typically involves psychological support and addressing any underlying anxiety or stressors. In some cases, medication may also be prescribed to help manage symptoms.
