LEMON: Fallon Fox is undefeated in her first two mixed martial arts bouts. She also came just forward and announced she is transgender. Fox is 37 years old and had kept her medical history private until she revealed to "Sports illustrated" she was born a man. She had gender reassignment surgery in 2006. Earlier, Fox told our Brianna Keilar why she chose to go public with the story.</s>FALLON FOX, MMA FIGHTER: I didn't plan to come out. There was a reporter that contacted me. He was told rumors that I was transgender, the term that I like to use. I pretty much had no choice, because he was digging around, asking people about me. So if it was not for that, I would have preferred to keep my personal medical history to myself, because it is a matter about my personal medical history. And I don't think that anybody should have to reveal the personal medical history if they don't feel they want to. I think that some people have a tendency not to pay attention to science in general, which is the way that we find out about the world around us. It is just a thing that happens to human beings. But I think, for the most part, the reaction has been positive. It is just some people, some of society just doesn't get it yet. And this is what we're trying to do is inform people and let them know about transgender athletes.</s>LEMON: Well, Fox is the first transgender athlete in the growing sport of mixed martial arts. I'm Don Lemon, at the CNN world headquarters in Atlanta. I'll see you back here one hour from now. THE SITUATION ROOM with Wolf Blitzer begins right now.
