Gestational vs. Traditional Surrogacy: Is the Baby Related to Me?

The short answer is no. In gestational surrogacy — which is what Borne and essentially every US agency does — the egg isn't yours and the baby carries none of your DNA. Here's the difference between the two kinds of surrogacy, why the industry moved almost entirely to one of them, and what it means for the handoff.

No - in gestational surrogacy, which is what Borne and essentially every US agency does, the embryo is made from the intended parents' or a donor's egg and sperm, so the baby carries none of your DNA. Traditional surrogacy, where the carrier's own egg is used and she is the child's genetic mother, is rare in the US now, and Borne does not arrange it.

This is the first question almost everyone asks, and often the only one that really matters before anything else can be considered. It bears repeating: in gestational surrogacy — which is what Borne and essentially every US agency does — the baby is not genetically related to you. The egg isn't yours. You carry a pregnancy created from someone else's genetic material.

That distinction has a name, a history, and consequences that reach into the law, the medicine, and the emotional experience of a journey. Here's the whole picture.

The two kinds of surrogacy

Gestational surrogacy

An embryo is created in a lab through IVF, using an egg from the intended mother or an egg donor and sperm from the intended father or a sperm donor. That embryo is transferred into your uterus. You carry the pregnancy and deliver the baby, and at no point does any of your genetic material become part of that child.

This is what people mean now when they say "surrogacy." It's what the medical guidance addresses, what state surrogacy statutes were written for, and what every reputable agency in the country practices.

Traditional surrogacy

The carrier's own egg is used, fertilized by the intended father's or a donor's sperm, usually through insemination rather than IVF. The woman carrying the pregnancy is the child's genetic mother.

This is the older arrangement — the one behind the court cases of the 1980s that shaped how the law thinks about surrogacy to this day. It is rare in the United States now, and agencies have largely stopped facilitating it.

Why the industry moved almost entirely to gestational

Two reasons, and both are about protection.

The law treats them completely differently. Most state surrogacy statutes were written specifically for gestational arrangements. Where a state has a clear path to a pre-birth order — the court document naming the intended parents before delivery — that path usually requires that the carrier not be genetically related to the child. Traditional surrogacy contracts are void or unenforceable in a number of states, and even where they're permitted, establishing parentage typically requires the carrier to relinquish parental rights after birth, sometimes through a formal adoption. That's a slower, more invasive process with far more room for something to go wrong.

It protects the carrier, too. A gestational carrier is never in the position of surrendering her own genetic child. The paperwork is cleaner, the emotional terrain is fundamentally different, and the legal risk of a parentage dispute is dramatically lower for everyone involved. Once IVF made gestational surrogacy reliably possible, there was very little reason to keep doing it the other way.

So whose egg is it?

One of three situations, and you'll know which before you match:

• The intended mother's egg. Common when she can produce viable eggs but can't safely carry a pregnancy — because of a uterine condition, a hysterectomy, a heart or kidney condition, or a history of severe complications.
• A donor egg. Used when the intended mother's eggs aren't viable, when there's a genetic condition to avoid, or when the intended parents are two men or a single father.
• Embryos created years ago. Many intended parents come to surrogacy after years of IVF, with frozen embryos already stored. Those embryos are often the reason they're here at all.

The sperm side follows the same logic — intended father or donor. None of this is a decision you make, but it's not hidden from you either. It comes up during matching, and it's a fair thing to ask about.

"Will the baby look like me?" and other real questions

No. The child's physical characteristics come from the egg and sperm. Eye color, hair, build, features — none of it traces to you. Surrogates commonly deliver babies of a different race than their own, and that's unremarkable in this world.

Blood type is the same story: the baby's blood type comes from the genetic parents and has nothing to do with yours. If you're Rh-negative and the baby is Rh-positive, you'll be managed exactly as you would in any pregnancy, with an Rh immune globulin shot.

The more interesting question is whether you influence the baby at all, and the honest answer is: not genetically, but not nothing either. Your body builds that pregnancy. Nutrition, blood supply, stress, and the uterine environment all shape fetal development, and there's an active research area looking at how a carrier's biology may influence which genes get expressed. What that research does not suggest is any change to the baby's DNA. The genome is fixed at fertilization and it isn't yours. But the idea that you're merely a container isn't accurate either, and most surrogates find that framing both truer and more satisfying than either extreme.

What this means for the handoff

This is where the genetic question stops being trivia. The most common worry people bring to surrogacy — usually voiced by a mother, a sister, or a friend rather than the candidate herself — is "won't you want to keep the baby?"

Research on gestational carriers is still limited, but what exists is reassuring, and it doesn't describe the grief people expect. Follow-up studies of surrogates years after delivery generally find low rates of lasting distress and high rates of satisfaction with the decision. Surrogates typically describe the handoff not as loss but as completion — the point of the whole thing finally arriving.

The absence of a genetic tie isn't the only reason for that, but it's a real part of it. Gestational carriers almost universally describe the pregnancy as belonging to someone else from the beginning — a thing they were doing for a family, not a child they were building into their own. Knowing from day one whose baby it is turns out to matter quite a lot.

None of which means you'll feel nothing. Most surrogates describe something in the days after delivery — a hormonal dip, a strange quiet, an ordinary postpartum period without a newborn at the end of it. That's real and it's planned for. It's just a different thing than losing a child.

What actually changes for you

Practically, the gestational structure shapes the whole journey:

• You'll go through an IVF cycle rather than an insemination — which means the medication protocol, the monitoring appointments, and a scheduled transfer at the intended parents' fertility clinic.
• Your legal position is a carrier, not a parent. In a state with a functioning pre-birth order process, the intended parents are named on the birth certificate and you never appear as a parent on any document.
• Your eligibility is evaluated on your ability to carry safely and well - your pregnancy history, your health, your uterus, your emotional readiness and the support you have at home - and not on genetic screening, because your genes aren't in play.

That last point surprises people. Your genes aren't screened the way the egg and sperm providers' are. What matters is your own health and pregnancy history, and whether you have the readiness and support to carry for someone else.
