The difference comes down to one thing: genetics. In gestational surrogacy, the carrier has no genetic connection to the baby; the embryo is created via IVF from the intended parents' or donors' egg and sperm. In traditional surrogacy, the carrier's own egg is used, which means she's the baby's biological mother. That single difference changes the medical process, the legal risk, and why almost every agency and clinic today only works with gestational surrogacy.
Traditional Surrogacy, Explained
Traditional surrogacy uses the carrier's own egg, fertilized with the intended father's or a donor's sperm—usually through intrauterine insemination (IUI) rather than IVF. Because the carrier is genetically related to the child, she has a biological claim that a gestational carrier doesn't have. This is the older, less common form of surrogacy, and most fertility clinics and agencies no longer offer it because of the legal complexity it introduces.
Gestational Surrogacy, Explained
Gestational surrogacy uses an embryo created through IVF from the intended parents' or donors' eggs and sperm, then transferred to a carrier who has no genetic link to the baby. This is the standard path almost every intended parent takes today. For the full step-by-step process, cost, and legal picture, see our complete guide to gestational surrogacy.
Why This Difference Matters More Than It Seems
Because a traditional surrogate is genetically related to the baby, parentage is legally murkier — some jurisdictions require additional steps, like a second-parent adoption, to fully secure the intended parents' rights after birth. Gestational surrogacy avoids this entirely: with no genetic claim from the carrier, a pre-birth legal agreement establishes the intended parents as the legal parents cleanly in the vast majority of jurisdictions that permit surrogacy at all.
This is also the main reason traditional surrogacy has largely disappeared from professional agencies and clinics — the legal risk it introduces isn't worth it when gestational surrogacy achieves the same outcome without a genetic claim to contest.
Which One Do Intended Parents Actually Use Today
Gestational surrogacy is the standard almost everywhere surrogacy is practiced, whether domestically or abroad. Traditional surrogacy still happens, but almost always as an informal arrangement between family or friends rather than through an agency or clinic. Professional programs, including every program in Kurbuo's network of vetted clinics in Colombia and the Dominican Republic, work exclusively with gestational surrogacy.
FAQ
Can a traditional surrogate keep the baby?
The legal risk is real: because she's genetically related to the child, her biological claim is stronger than a gestational carrier's, and in some jurisdictions securing full parentage requires extra legal steps after birth. This is the core reason most professional programs no longer offer traditional surrogacy.
Can a gestational surrogate keep the baby?
No. She has no genetic connection to the baby, and a legal agreement signed before treatment begins establishes the intended parents as the legal parents.
Is traditional surrogacy cheaper than gestational surrogacy?
It can avoid some IVF-related costs, but the added legal complexity and risk usually outweigh the savings—which is why it's rarely offered as a program option today.
Does Kurbuo work with traditional surrogacy programs?
No. Kurbuo's network of vetted fertility clinics in Colombia and the Dominican Republic works exclusively with gestational surrogacy—the path with the clearest legal protection for intended parents.
