Organ transplants require that the donor have a blood type that is compatible with the recipient.
Why is that not a requirement when you are actually growing the organs themselves during a surrogate pregnancy?
Thanks in advance!

It’s not that it doesn’t matter, but it doesn’t matter as much.
The placenta is a filter between mother and child, so there is very little blood or tissue Mix between the two. There still can be issues relating to blood typing. Baby’s blood cells are detectable in the mother’s blood, that’s how current generation genetic tests on pre-term fetus work. So if there is a mismatch between mother and child it can cause illness or stress for either mother or child, but rarely is this stress a fatal issue.
