The idea that (1) doctors could do a successful womb transplant into a male, and (2) this could be used to carry a pregnancy to term, (3) in the lifetime of anyone who's alive today, is absolutely delusional.
ANY transplant is an extremely intense, risky procedure that even in the most ideal circumstances, takes a huge toll on the recipient's body; It requires powerful, dangerous immuno-supressant drugs, to stop your body's natural tendency to reject the new organ/body-part as a foreign body. These immuno-supressants really fuck with your physiology- They leave you vulnerable to other infections, because it's basically just removing the body's natural defense against infection/invasive threats.
But a womb transplant INTO A MALE isn't the same as normal transplants (which are risky/harmful enough); Because a normal transplant, you have someone who STARTED OFF with a heart, or kidney, or whatever organ; That organ has some disease/defect, so you find a donor organ, to replace the flawed organ the patient ALREADY had; The patient's body is ALREADY used to having a kidney, with all the nerves, blood supply etc for a kidney; The surgeons "merely" need to swap WHICH specific kidney those nerves and blood supply are supporting (which of course is a huge, dangerous, difficult challenge- Rejection and complications are very common. But IN COMPARISON to a male womb transplant, all that stuff becomes "merely" swapping one kidney, for another)
But with male womb transplant, things get infinitely harder because it ISN'T a "swap"- It's introducing a totally new organ, into a body that was never equipped to support it. Even the "basic" stuff that any organ needs, like nerves, blood supply etc become a giant challenge, because a surgeon can't just scratch-build nerves or veins, from nothing.... Add to that the fact that a womb, in order bring a pregnancy to term, needs FAR MORE complicated support/supply of resources, than the support that ANY internal organ needs; A pregnant woman's body supplies a super-complex, dynamic, responsive supply of nutrients and hormones, that varies with the baby's growth, health, and specific needs. The idea you could replicate that, with the relatively crude blood supply used in a transplanted organ, is insane.
But probably the BIGGEST obstacle, is idea that you can destroy a man's immune system, to the point where his body doesn't reject this totally alien organ which his body never had before, never was MEANT to have... and then ALSO have him bring a pregnancy to term, with his weakened immunity AND the resulting greater exposure to infection.
Getting a male body to not a reject a uterus would be a huge, unparalled medical achievement in the first place... but THAT goal has basically THE COMPLETE OPPOSITE requirements, to the seperate goal, of having him actually carry a pregnancy; The transplant requires a WEAK immune system, which won't reject a foreign organ. The pregancy requires a STRONG immune system, which will protect a vulnerable, developing fetus. There's just no possible way to juggle these two, totally contradictory requirements.
But even if we just ignore ALL those medical barriers, and assume the tranny-logic is correct; People ARE just like Legos, or Tupperware, where you can just swap one part for another, no drama. "Trans women" DO have some magical link to womanhood, that "cis" men lack, making them especially womb-receptive... Trannys STILL wouldn't be satisfied with a womb transplant- Because they STILL couldn't be "bred", by actually being fucked, which is the main focus of the whole fetish; Even WITH a magical womb-transplant, they'd need to have doctors fertilize an egg in the lab, and then surgically implant it- No actual "impreganation", in the sense that an "impregnation fetishist" cares about... And the OTHER event they fetishize, the actual birth, couldn't be done in the natural way they alway focus on, either; It'd need to be a C-section, probably early and induced. Coz there's no way in hell that an inverted penis/amhole is going to work as a birth canal.
It's the nature of troonism, that they will ALWAYS focus on whatever a woman can do (eg, get impregnated by sex. Physically give birth), that the troon CAN'T do. And it's the nature of biology/reality, that there will ALWAYS be a huge gap between those two things. They'll just do more and more harm, chasing the impossible.
The whole "womb transplant" thing is just an absolute pipe-dream. But I think it IS a good way to peak normies to the extent that troons will go to for their fetishism; It's such disturbing, ghoulish imagery; These men being so desperate to literally harvest the internal woman-parts from dead women, so they can stuff the prized, female innards inside themselves, to help them LARP as "REAL women". It's getting so very close to literally demanding to skin women, and walk around wearing them as clothing, like Ed Gein or Buffalo Bill.
