In the entire world, Rugen (如根 
, 汝根 , Rugen 
) is quite a rare primarily male, but very infrequently female given name. The first name Rugen is characteristic of China, where it is a rare principally boy's, but very infrequently feminine name, Philippines, where it is a rare largely masculine, but uncommonly feminine name, and India, where it is an extremely rare epicene name. Very seldom, Rugen is the last name as well as the forename.
