All around the world, Mennen (Minor 
, منن 
, Mennen 
) is quite a common epicene forename. The forename Mennen is habitual in Costa Rica, where it is quite a common masculine name, Sudan, where it is quite a rare predominantly female, but scarcely male name, and Guatemala, where it is quite a rare masculine name. Not in comparison with a country's population, this name is the most popular in Costa Rica, Sudan, and the United States. More frequently, Mennen is the last name as well as the forename.
