All over the world, Гулен (Gülen 
, Gulen 
, Goulen 
) is quite a common principally girly, but very seldom boy's given name. The first name Гулен is characteristic of Turkey, where it is quite a common feminine name, Germany, where it is a very rare female name, and India, where it is a very rare gender-neutral name. More prevalently, Гулен is the last name as well as the forename.
