In order to make it works you have to:

1. create a content type with categories

2. create a workflow action (velocity script actionlet)

#set($parentCategory = $categories.getCategoryByKey('ageOrGender'))
#set($cats= $categories.getChildrenCategories($categories.getCategoryByKey('ageOrGender')))
#set($contentDeps = $workflow.copyContentletDependenciesBuilder().categories($cats).build())
$workflow.setContentletDependencies($contentDeps))

Create a new type and fire the new action, the categories of age or gender will be assigned to the contentlet
