Also known by the name "shook yong", koro is a mental disease prevalent among East Asian males, the symptoms of which are chiefly an irrational fear that the subject's "membrum virile" will disappear up into his body.

Sufferers often resort to the use of elaborate clamps or clasps to alleviate the fear.
