Some women become gestational carriers because:
They love their own children and have completed their families and are empathetic of others who are in need of assistance in creating a family.
They have had enjoyable, uncomplicated pregnancies.
The surrogacy process may enable them to stay at home with their children and/or enable them to contribute financially to their family.
It is an opportunity for paying it forward/blessing someone; regardless of race, religion, political views, or education level.
