Inner-thigh skin is often used in those surgeries because it is soft, often hairless and the scars are not that visible UNLESS you are in a bathing suit.

Yes, but they didn't use inner thigh skin! They used skin from the front of the thighs where it would be most visible. That's the whole point! They could have used skin from the inner thighs or other more hidden and discreet places I mentioned, especially the inner upper arms: skin from there is also soft, pliable and hairless.

The physicians who did Jazz's surgeries are plastic/cosmetic surgeons. Such surgeons are keenly aware of the placement of the incision scars they make, and locating incision scars so that they will not be seen, is fundamental to the "art" of cosmetic/plastic surgery. Go ask any plastic surgeon. Better yet, go make an appointment with one. The placement of incisions and attempts to minimize and hide scarring are things that will be discussed right up front in any standard consult.

the scars are not that visible UNLESS you are in a bathing suit.

You say that as though wearing a bathing suit is a rare event. But Jazz Jennings is a young person who lives in southern Florida, a place where wearing a bathing suit is very common. In that part of Florida, donning a bathing suit and going swimming are things many people do every day of their lives, 365 days a year. Jazz not only frequents the beaches in Florida, he has an in-ground pool in his backyard where throughout his life he and his whole family have always spent a whole lot of time day in and day out. It's not like wearing a bathing suit is an occasional thing for Jazz; it's everyday attire.

What's more, anyone familiar with Jazz's story knows that his preference for "girly" swim wear and his desires to be a "mermaid" were the main reasons he was labelled "trans" as a toddler to begin with. On the TV series, teenage Jazz made it very clear that being seen as a sexy bathing beauty with "porn star tits" who can really rock a bikini or a revealing high-thigh cut one-piece is one of his life goals.

Jazz's surgeons knew all this. And yet look at what they did.

Not saying any of this is right or good for a human being, but those speculations you threw are pretty out there...

Did you watch the TV series? These physicians are unethical madmen who made up the procedures they used on Jazz in the OR as they were operating - on the fly, as it were. It was entirely experimental. What they did was not planned out and well-researched ahead of time, nor was it gone over with Jazz and his parents in detail beforehand, either.

The physicians who put Jazz on puberty blockers at 10-11 and on estrogen at 12 never bothered to consider for a moment - or to inform Jazz and his parents - that this would mean Jazz would end up at 17 with the genitals of a little boy. As a result, they did not tell him or his parents that when it came time for Jazz to have his genital reconstruction surgery, there wouldn't be enough penile and scrotal tissue for Jazz to have the surgery customarily done in these cases.

A number of reputable surgeons Jazz and his family consulted said they could/would not do genital surgery on him as Jazz didn't have enough genital tissue for such an operation to be a success. Others said they'd only consider it if Jazz went off the puberty blockers and estrogen to allow his genitals to develop further, or undertook steps they recommended to enlarge his scrotum, including using testosterone cream on his bits and using a series of progressively larger and larger water balloons inserted in the ball sac to stretch out the skin.

Unhappy with these responses, and surprised by them too, Jazz and his parents shopped around further until they found surgeons willing to wing it.

those speculations you threw are pretty out there...

I've looked into the history and medical practices of Jazz's surgeons Marci Bowers MD and Jess Ting MD at some length. IMO, what they are doing to vulnerable, mentally unwell people like Jazz Jennings is "pretty out there." Why is my saying I oppose it and pointing out how weird it is for them to have located those scars where they did so they would be most visible and would be sure to draw attention to that precise part of Jazz's body more "out there" than the actions these physicians have taken?
