> So I mean, you probably don't want to have any leaks or weak stitches in your uterus transplant...

With this sort of surgery, they wouldn't be cutting into the uterus (womb) itself when extracting it from the donor, but instead will cut around it to remove it, along with some very essential plumbing. The receiving mum will also be on industrial-strength immune suppressants anyway.

Where you DO have to worry about leaks and weak stitches is with said plumbing (uterine arteries and veins) -- they have to support virtual firehoses of blood through the duration of pregnancy, and their damage is one reason why a delivery can go south very, very quickly. Obstetric medicine is definitely a high-risk sport, which is why their malpractice insurance rates are head and shoulders above any other medical specialty. But I digress...
