How can a pregnancy surrogate carry a zygote/fetus when surrogate and baby are not biologically related?

342 views

Specifically wondering why surrogate’s body doesn’t attack the zygote/fetus as if it’s a foreign body.

Of course as I’ve typed this out I’m wondering if it’s the same reason babies aren’t attacked in the womb in any other situation, the placenta?

Baby’s can be attacked. In fact if the baby is RH positive, and the person who’s uterus that they are growing in, is not RH positive, antibodies will be created and attack the baby.

In this case the doctors will have to administer medicine to stop this from happening.

That being said, your body is not testing the DNA of every cell that comes in, to attack it if it is foreign. It is mostly reacting to things that it knows will cause trouble. That is why new viruses and the like, can cause so much havoc as the body will allow it to gain a pretty strong foothold before it decides to spend the energy to kick it out.
