One of the most common questions intended parents ask early in the surrogacy process is: Whose egg is used?
The answer depends on the type of surrogacy being used — but in modern surrogacy, and in every Hatch journey, the egg comes from either the intended mother or an egg donor, never from the surrogate herself.
In this article, we’ll explain how eggs are selected, the difference between gestational and traditional surrogacy, and what this means for genetics, legal parentage, and your surrogacy journey.
The source of the egg determines whether the surrogate is genetically related to the baby.
Because gestational surrogacy offers clearer legal protections and emotional boundaries, it’s now the standard in most professional surrogacy programs, including Hatch.
In gestational surrogacy, eggs are retrieved from the intended mother or an egg donor through in vitro fertilization (IVF). The egg is fertilized with sperm from the intended father or a donor, and the resulting embryo is transferred to the surrogate’s uterus.
This process ensures the surrogate’s role is purely to carry the pregnancy, not to contribute genetic material. This is why, in gestational surrogacy, surrogates do not share DNA with the baby.
Many intended parents use an egg donor if:
Traditional surrogacy involves the surrogate being artificially inseminated with sperm from the intended father or a donor, using her own egg to conceive. This makes her both the biological and birth mother of the child.
While traditional surrogacy played an important role in the history of reproductive medicine, it is rarely used today due to:
At Hatch, we work exclusively with gestational surrogacy because it provides the clearest, safest path for everyone involved.
In gestational surrogacy, the intended parents are established as the legal parents from the outset in the surrogacy agreement. This clear legal framework is one reason why intended parents choose to work with a trusted agency.
In traditional surrogacy, the surrogate’s genetic connection can create legal complexities that often require additional court proceedings to establish parentage — another reason this approach has become uncommon.
Choosing the right egg source is just one part of a safe and ethical surrogacy journey. At Hatch, we guide intended parents through every step — from selecting an egg donor to finding the right match through our surrogate matching process.

In all Hatch surrogacy journeys, the egg comes from the intended mother or a donor — never from the surrogate. This ensures there is no genetic connection between the surrogate and the baby, creating a clearer and more secure path to parenthood.
