when talking about organ transplants,what is the percentage of the body rejecting the organ that's allowed?

Question

i just read about womb transplant.
so what's the percentage of the body rejecting the new organ that's allowed before a transplant is usually considered to be dangerous?
please give me exact figures,and if I would really appreciate it if you could state your sources.
thank you.

Answer 1

I have never heard of a womb transplant. I have a transplanted liver and I was told that there was about a 10% chance of my body rejecting it. I now take a medicine to prevent rejection.
