Facebook's 56 gender options and what they mean
Facebook has expanded its gender options to a mindboggling array of terms encompassing trans and gender-nonconforming users.
The social media company said the change offers its 159 million monthly users in the United States more choices in the way they describe themselves.
Users have lobbied Facebook for years to offer alternative gender choices. The company has also been publicly supportive of lesbian, gay, bisexual and transgender (LGBT) rights, and founder Mark Zuckerberg, along with employees, took part in San Francisco's gay pride parade last year.
Facebook's move has been welcomed by the LGBT community in the US. Sarah Kate Ellis, president of American gay rights organisation GLAAD, wrote in a blog post (http://www.glaad.org/blog/facebook-introduces-custom-gender-field-allow-...): "This new feature is a step forward in recognising transgender people and allows them to tell their authentic story in their own words."
So far reaction from the conservative right in the US has been relatively muted, although a spokesman for Focus On The Family, an influential religious organisation based in Denver, told Associated Press: "Of course Facebook is entitled to manage its wildly popular site as it sees fit, but here is the bottom line: It's impossible to deny the biological reality that humanity is divided into two halves - male and female."
Here is a glossary of the gender definitions and what they mean.
Agender: Someone who does not have an internal sense of gender.
Androgyne/Androgynous: A person in whom both feminine and masculine traits are integrated in his/her sense of gender.
