Throughout the world, 西科 (Xike 
, 西科 , Sicoe 
) is a rare mostly boy's, but uncommonly girly forename. The forename 西科 is characteristic of Romania, where it is a rare unisex name, China, where it is a very rare predominantly masculine, but scarcely female name, and Vietnam, where it is a very rare boy's name. Much less frequently, 西科 is the last name as well as the forename.
