In traditional surrogacy, the woman carries a child conceived by her own eggs and donor sperm. After giving birth, the woman may not be given any parental rights, but she will be genetically linked to the child.
In gestational surrogacy, the woman carries a child conceived by other couples/intended parents. The embryo is developed using IVF (In-Vitro Fertilization). Therefore, the surrogate mother won't have any legal rights or genetic relationship with the baby.
