What are the possible values ​​for the gender field in the Facebook Graph API?

Question

Facebook recently introduced many options for gender issues besides men and women. Is there a list of all the possible values ​​for the "gender" field in the Graph API?

Answer 1

Ok, I found out. I tried setting up a custom gender in a test account.

Possible values ​​remain only "male" and "female". When you select a custom gender, and then enter one of the custom gender groups, that is, the field next to the bottom using the option - Which pronoun do you prefer?

Here, depending on what you choose, the gender field returns “male” or “female”, regardless of what you type in “Gender”. However, if you select "Neutral", then the Graph API does not have a "gender" field in it.

This article lists all the possible sexes that they were able to find, but they note that Facebook has not published an official list. http://www.slate.com/blogs/future_tense/2014/02/13/facebook_custom_gender_options_here_are_all_56_custom_options.html
