There has never been any official claims of he/she/it being transgender. But the pics make it pretty obvious... on top of its 6"9" height! (Yes, a few biological women have topped 7 feet, but they had congenital issues and were never healthy, much less able to play sports at a high level)
I've been asking what prison they're going to put her in for a long time!

There are some women that are tall that are just fine, it is rare but it happens especially among certain ethnic groups that tend toward tall people. A quick search on google had a 7-foot basketball player (female) in China which occasionally has really tall people, I went to University with a Japanese girl who was about 6 feet, she towered over everyone else and was part of that first generation (boomers) in Japan that got enough nutrition that the ancient genetics came back. Other Google showed a 7-foot happily married model in Brazil (though her height did come from a tumor) along with a number of other athletes.
As more and more people around the world have better access to good nutrition as do many people in the USA, more people are growing to the full heights that their genetics will allow.
My major professor was part of excavation from Mesolithic England, a settled village from about 8,000 years ago when people were first settling down but still hadn't gotten smaller from "the farming effect." The AVERAGE height of men was 6 feet but some were much taller, the AVERAGE height of the women was 5'8" but some were the same height as the taller men.
You get groups of people with part African ancestry and occasionally Native Americans whose genetic blueprints are usually 5'8" up to 7.5 Feet tall. I'm not talking about people with growth hormone problems that cause them to grow too tall (like Andre the Giant). We have a kitty with that condition we named Rory but we kiddingly call him Andre, he has a huge face and paws and probably won't live more than a decade or so.
I have no idea about this women, but some ladies are naturally flat (my grandmother was) and many perfectly biologically female athletes have NATURALLY high testosterone levels. My housemate does, it really helped her with weight lifting.
