Introduction
Surrogacy is a life-changing fertility option for many intended parents, but one common question arises: Whose DNA does the baby have? Understanding the genetic aspects of surrogacy can help clear doubts and misconceptions surrounding this assisted reproductive technique.
Types of Surrogacy and Genetic Connection
The genetic makeup of a surrogate baby depends on the type of surrogacy used:
1. Traditional Surrogacy
In traditional surrogacy, the surrogate mother’s egg is used, and it is fertilized with the intended father’s or donor’s sperm through artificial insemination (IUI). This means that the surrogate mother is the baby’s biological and genetic mother. Because of this genetic link, traditional surrogacy is less common and often carries more legal and emotional complexities.
2. Gestational Surrogacy
Gestational surrogacy is the most widely used method today. In this process:
- An embryo is created through in vitro fertilization (IVF) using the intended mother’s egg (or donor egg) and the intended father’s sperm (or donor sperm).
- The embryo is then transferred into the surrogate mother’s uterus.
- The surrogate carries the pregnancy but has no genetic link to the baby.
Thus, in gestational surrogacy, the baby’s DNA comes from the intended parents or donors, not the surrogate mother.
Whose DNA Does the Baby Have in Surrogacy?
- In traditional surrogacy – The surrogate mother’s DNA is present since her egg is used.
- In gestational surrogacy – The baby’s DNA comes from the intended parents (or donors), and the surrogate mother has no genetic connection to the child.
Factors That Influence the Genetic Makeup of a Surrogate Baby
- Intended Parents’ DNA – If both parents contribute their sperm and egg, the baby will inherit their genetic traits.
- Donor Gametes – If donor sperm or eggs are used, the baby will inherit genetics from the donor and one intended parent.
- No DNA from the Surrogate – In gestational surrogacy, the baby does not inherit any DNA from the surrogate mother.
Why Gestational Surrogacy is Preferred?
Gestational surrogacy is favored for several reasons:
- No legal parental rights issues – Since the surrogate has no genetic link, legal complexities are reduced.
- Maintains the intended parents’ biological connection – If using their own gametes, the baby carries their DNA.
- Emotional and ethical considerations – Traditional surrogacy can create emotional challenges due to the biological link.
Conclusion
The genetics of surrogacy depends on the method chosen. In traditional surrogacy, the surrogate contributes her DNA, while in gestational surrogacy, the baby’s genetic material comes entirely from the intended parents or donors.

FAQs
Q1: Does the baby look like the surrogate mother?
A: In gestational surrogacy, no. The baby’s genetic traits come from the egg and sperm providers.
Q2: Can a surrogate baby inherit traits from the surrogate?
A: No, gestational carriers only provide a nurturing environment for the baby; they do not pass on DNA.
Q3: Who is the biological mother in surrogacy?
A: In traditional surrogacy, the surrogate is the biological mother. In gestational surrogacy, the biological mother is the egg provider.
Q4: Can intended parents use donor sperm or eggs in surrogacy?
A: Yes, intended parents can opt for sperm or egg donation if needed.
