Allow you to add more gender types in your component.

<?php
function my_component_init(){
		ossn_add_hook('user', 'gender:types', 'my_component_hook');
}
function my_component_hook($hook, $type, $genders, $instance){
		$genders[] = 'new_gender_key';
		return $genders;
}
ossn_register_callback('ossn', 'init', 'my_component_init');

After adding new_gender_key you need to add this also in language file

'new_gender_key' => 'New Gender',
