Surrogacy and DNA: Is the Baby Genetically Related to the Surrogate?

If you're exploring surrogacy as a path to parenthood, it's natural to have questions—especially when it comes to genetics. Does a surrogate pass on any DNA to the baby? Are the surrogate and child biologically connected? And what about legal rights?

We’re here to break it all down for you—clearly and simply.

Traditional vs. Gestational Surrogacy: What’s the Difference?

There are two main types of surrogacy: traditional and gestational. Today, gestational surrogacy is the more commonly used approach.

Traditional Surrogacy: The surrogate uses her own egg, making her biologically related to the baby. This process is now used much less frequently due to the emotional and legal complexities it can involve.

Gestational Surrogacy: The surrogate carries an embryo created through in vitro fertilization (IVF) using the intended parent(s)’ or donor eggs and sperm. In this case, the surrogate has no genetic connection to the baby.

Once the embryo is created in a lab, it’s transferred to the surrogate’s uterus. She carries the pregnancy, but does not contribute any DNA to the child.

Does a Surrogate Share DNA With the Baby?

In gestational surrogacy, no—the surrogate does not share DNA with the baby. Since the embryo is created using the intended parents’ or donors’ reproductive cells, the surrogate simply carries the pregnancy without contributing genetic material.

This means there’s no biological link between the surrogate and the child. So, any carefully chosen and medically approved gestational carrier can help bring your child into the world without passing on her genetics.

Do Surrogates Have Legal Rights to the Baby?

In gestational surrogacy arrangements, the surrogate has no legal rights to the child. Legal contracts are put in place before the process begins, outlining the rights and responsibilities of all parties involved.

This pre-birth legal work gives intended parents peace of mind, helping ensure a smooth process from pregnancy to parenthood.

Traditional surrogacy can involve more legal risks because the surrogate is genetically related to the baby—one reason it is far less common today.
