Reciprocal IVF is when two people who identify as women decide to have a baby together using In Vitro Fertilization (IVF). It's called "reciprocal" because each person takes on a different role in the process.
One person's eggs are retrieved from their body and fertilized with donor sperm in a lab. The resulting embryos are then transferred into the other person's uterus, where they hopefully implant and grow into a baby.
So, let's pretend there's a couple of ladies named Rachel and Sarah who want to have a baby together. Rachel decides she's going to be the one to provide the eggs. She has to take some medicine that helps her make lots of eggs, which are then taken out of her body using a special procedure called "egg retrieval."
Meanwhile, Sarah's job is to get her body ready to be a good home for the embryos. She takes some medicine too, to make her uterus super cozy and welcoming. When the embryos are ready, they're put into a little tube and placed inside Sarah's uterus, sort of like a tiny seed that will hopefully grow into a baby.
After that, Rachel and Sarah wait and hope that one of the embryos sticks and makes a baby. And if everything goes well, they'll get to be moms together!
