Traditional surrogacy is an arrangement where a woman carries a pregnancy using her own egg, making her the biological mother of the child she delivers. This is the key distinction from gestational surrogacy, where the surrogate has no genetic connection to the baby. Because the surrogate provides the egg and carries the pregnancy, traditional surrogacy raises unique legal and emotional considerations that have made it increasingly rare in clinical practice.
How Traditional Surrogacy Works
In traditional surrogacy, the surrogate’s own egg is fertilized, typically through intrauterine insemination (IUI), using sperm from the intended father or a donor. This is a relatively simple medical procedure compared to gestational surrogacy, which requires a full round of IVF to create an embryo from a separate egg donor or intended mother and then transfer it to the surrogate.
Because IVF isn’t needed, traditional surrogacy involves fewer medications, fewer clinic visits, and a less physically demanding process for everyone involved. The surrogate doesn’t need to take hormones to prepare her uterus for an embryo transfer, and there’s no egg retrieval surgery for a separate donor. This simplicity is one reason some intended parents, particularly single men or same-sex male couples, have historically considered traditional surrogacy as an option.
Traditional vs. Gestational Surrogacy
The fundamental difference comes down to genetics. In gestational surrogacy, the surrogate carries a baby created from someone else’s egg and sperm. She has no biological relationship to the child. In traditional surrogacy, the surrogate is the egg donor, which means the child carries her DNA. This genetic link is what makes traditional surrogacy legally and ethically more complex.
Gestational surrogacy now dominates clinical practice. Data from the CDC’s 2022 assisted reproductive technology summary shows that only about 1.5% of all ART cycles involved a gestational carrier, and traditional surrogacy is even rarer than that. The American Society for Reproductive Medicine describes traditional surrogacy as “uncommon in clinical practice” today, largely because the genetic connection between surrogate and child creates legal vulnerabilities that most fertility professionals and intended parents prefer to avoid.
The Legal Landscape in the U.S.
Traditional surrogacy laws vary dramatically from state to state, and the legal picture is considerably more complicated than it is for gestational surrogacy. Several states explicitly allow it, others ban it, and many fall somewhere in between with limited legal protections.
States that permit traditional surrogacy include Connecticut (under the Connecticut Parentage Act), Washington, D.C., Florida, Massachusetts, Kansas, Washington state, and Wisconsin. Each has its own framework. In Massachusetts, for instance, if a genetic surrogacy agreement is validated by a court before embryo transfer, the intended parent’s legal parentage is automatic at birth. In Florida, the surrogate has 48 hours after birth to rescind her consent. Kansas allows compensated traditional surrogacy but requires additional legal steps like confirmatory adoptions and donor agreements, with criminal penalties for failing to comply.
On the other side, New York considers traditional surrogacy against public policy, even though it legalized gestational surrogacy in 2020. Kentucky prohibits contracts that compensate a woman for artificial insemination followed by termination of parental rights, effectively banning traditional surrogacy. Indiana makes both gestational and traditional surrogacy contracts void and unenforceable if they contain certain provisions. Maryland permits traditional surrogacy but flags it as “legally risky.”
This patchwork means that where you live, or where the surrogacy takes place, has enormous implications for whether the arrangement is legally protected. Internationally, the picture is similarly restrictive. In the U.S. generally, traditional surrogacy finds little to no legal support compared to gestational arrangements. Portugal bans traditional surrogacy except in narrow circumstances, such as when the intended mother is completely unable to produce eggs.
Why the Genetic Link Creates Legal Risk
The core legal challenge is straightforward: because the surrogate is the biological mother, she has a stronger claim to parental rights than a gestational carrier would. In many jurisdictions, a woman who gives birth to a child she is genetically related to is presumed to be that child’s legal mother. Overriding that presumption requires either a pre-birth court order (available in only some states) or a post-birth adoption process.
For the intended parent who is not biologically related to the child, establishing legal parentage often requires a second-parent adoption or stepparent adoption. In California, for example, this involves filing specific court forms, signing adoption agreements before a notary, and paying a filing fee. While the process can be straightforward when uncontested, it adds a layer of legal uncertainty that doesn’t exist in gestational surrogacy, where both intended parents can often be named on the birth certificate from the start.
The risk that a traditional surrogate could change her mind and seek to keep the child is not just theoretical. It’s the reason most surrogacy agencies, fertility clinics, and reproductive attorneys steer clients toward gestational surrogacy. When a surrogate has no genetic tie to the baby, courts in most states treat her similarly to a temporary caretaker rather than a parent.
Cost Differences
Traditional surrogacy can be significantly less expensive than gestational surrogacy because it eliminates the need for IVF and, in many cases, egg donation. The average cost of gestational surrogacy in the U.S. in 2025 ranges from $100,000 to $140,000, and can reach $250,000 or more depending on the situation. That total typically includes agency fees ($35,000 to $55,000), surrogate compensation and expenses ($65,000 to $95,000 when factoring in all benefits), legal fees ($10,000 to $25,000), and medical costs.
A single IVF cycle alone runs $25,000 to $35,000, and egg donation adds another $30,000 to $40,000 on top of that. Traditional surrogacy sidesteps both of those expenses entirely. However, legal costs may actually be higher for traditional surrogacy because the parentage process is more complex, and many intended parents need adoption proceedings on top of the surrogacy contract. Still, the overall price tag tends to be lower, which is part of its appeal for intended parents working within a budget.
Who Considers Traditional Surrogacy
Traditional surrogacy is most often considered by single intended fathers, same-sex male couples who want one partner to be the biological father, or intended parents who want to avoid the physical demands and expense of IVF. In some cases, it appeals to people who already have a willing surrogate in their life, such as a friend or family member, and want a simpler medical process.
Finding a fertility clinic willing to facilitate traditional surrogacy can be difficult. Many clinics decline to participate because of the legal risks, and most surrogacy agencies focus exclusively on gestational arrangements. Intended parents pursuing traditional surrogacy often work with a reproductive attorney from the very beginning to navigate state-specific laws and draft agreements that provide as much legal protection as possible. The surrogate also typically has her own independent attorney to ensure her rights and interests are represented separately.
