What's your Facebook gender: 'He', 'she', 'they' or…

Facebook on Thursday freed members from the bonds of being either male or female, letting people opt for custom genders such as transsexual or ‘intersex’ on the social network.

Along with adding scores of ‘custom gender’ options on profile pages, Facebook is letting members select which pronouns they wish used when referring to them in posts or messages.

Facebook users could opt to be referred  to as ‘he/him’ or ‘she/her’, or by a neutral ‘they/their’ choice.

"While to many this change may not mean much, for those it affects it means a great deal," Facebook said in a post at its Diversity page that included a picture of a rainbow flag on display on the company's campus in the Silicon Valley city of Menlo Park.

Facebook said it worked with lesbian, gay, bisexual and transgender activist groups to create a thorough list of gender options, which can be found in an "other" category on profile About pages.

Custom genders are only available to those who use Facebook in US English but the company planned to expand the range in the future
