Thank you. I never realized that the organ is always rejected, albeit somewhat incrementally if immunosuppressants are used and effective.
Wow. That opened my eyes.
I wonder if the genetic differences between male and female tissue would make a cross-gender transplant even more "foreign" and, therefore, more vulnerable to the process of rejection.
And that is the first thing that sprang to my mind. Perhaps we have been wrong to ignore sex when selecting a transplant recipient.
Most people think that transplant=cure. It is more like remission.
