I heard of this disorder a few years ago. I think that the "gender identity" disorder is closely related.
I do not think that "social scientists" are going to be able to tease out the root causes of these disorders. They are only going to be understood through the efforts of research psychologists, psychiatrists, and neurologists, to name a few scientific disciplines with the expertise to study mental disorders.
At the moment, our media is no better than the circuses of the 1800s who paraded "freaks" in front of the public for profit. The media have no conscience.
I just came across this great website: www.SexChangeRegret.com. It is written by a man who had the procedure then he realized that he made a mistake. There are some other examples from other people who had he same experience. Pass it on, the media will be lying like crazy about this since Jenner came out so it would be helpful to get the truth out as much as possible.
