Surrogacy Explained
Surrogacy is an arrangement where someone carries and delivers a baby for intended parents. In gestational surrogacy: the dominant modern form, the carrier has no biological connection to the child. The embryo is created using IVF and then transferred to the carrier. Legal agreements determine parentage before and after birth.
Definition of Surrogacy
Surrogacy is a reproductive arrangement in which a woman (the gestational carrier or surrogate) carries a pregnancy and delivers a child on behalf of another person or couple (the intended parents). In gestational surrogacy, the carrier has no genetic relationship to the child. The embryo is created through in vitro fertilization using gametes from the intended parents, donors, or a combination thereof.
Surrogacy is not adoption. The child is genetically related to one or both intended parents (or to selected donors). The carrier has no legal parental claim under a properly executed gestational carrier agreement. The legal, medical, and financial structure of surrogacy is complex and jurisdiction-dependent.
Types of Surrogacy
Gestational Surrogacy
The carrier has no genetic link to the baby. An embryo is created via IVF using the intended parents' gametes, donor gametes, or a combination. This is the most common form of surrogacy practiced today and is the type used in the vast majority of US surrogacy arrangements. The carrier's uterus is the gestational environment; her DNA is not part of the embryo.
Traditional Surrogacy
The carrier's own egg is used, making her the biological mother of the child. Fertilization may occur via IUI (intrauterine insemination) or IVF. Traditional surrogacy is rare in modern practice because it creates a biological parental claim that complicates legal parentage. Most surrogacy agencies and attorneys advise against it due to legal risk.
When people refer to "surrogacy" in contemporary contexts, they almost always mean gestational surrogacy. The legal, medical, and ethical frameworks discussed here apply primarily to gestational arrangements.
Who Uses Surrogacy
Surrogacy is used by individuals and couples for whom pregnancy is medically impossible, medically unsafe, or biologically unavailable:
- • Same-sex male couples. Surrogacy is the primary pathway for gay men to have genetically related children. One or both partners may provide sperm, combined with donor eggs.
- • Single men. Solo fathers increasingly use surrogacy with donor eggs to build families independently.
- • Women with medical conditions. Absent uterus (congenital or surgical), Asherman syndrome, uterine malformations, or conditions where pregnancy carries unacceptable health risk (severe cardiac disease, uncontrolled autoimmune conditions).
- • Repeated IVF failure. Couples who have achieved euploid embryos but experienced recurrent implantation failure or pregnancy loss may use a gestational carrier to carry a transferred embryo.
- • Cancer survivors. Patients who preserved embryos or gametes before treatment but cannot safely carry a pregnancy post-treatment.
Surrogacy is not a convenience choice. It is a medically, legally, and financially complex pathway undertaken when other reproductive options are unavailable or carry unacceptable risk.
The Surrogacy Process
1. Agency selection and matching
Intended parents select a surrogacy agency (or pursue an independent match). The agency screens and matches a gestational carrier based on medical history, psychological evaluation, and mutual compatibility.
2. Legal agreements
A Gestational Carrier Agreement (GCA) is drafted and executed by separate attorneys representing the intended parents and the carrier. This must be completed before any medical procedures begin.
3. Medical screening
The carrier undergoes comprehensive medical and psychological screening. Intended parents complete infectious disease testing and any required evaluations.
4. IVF cycle and embryo creation
Eggs are retrieved (from intended mother or donor), fertilized (with intended father's or donor sperm), and embryos are cultured and potentially tested via PGT-A.
5. Embryo transfer
A selected embryo is transferred to the carrier's prepared uterus. The carrier takes estrogen and progesterone to prepare her endometrium.
6. Pregnancy and monitoring
The carrier gestates the baby with regular prenatal care. Intended parents may attend appointments depending on geographic proximity and agreement terms.
7. Birth and parentage
Parentage is established through a pre-birth order (PBO) or post-birth order depending on jurisdiction. The intended parents are named as legal parents on the birth certificate.
Legal Considerations
Surrogacy law is jurisdiction-specific. There is no federal surrogacy law in the United States. Each state has its own legal framework, ranging from explicitly permissive to effectively prohibitive:
- • Surrogacy-friendly states (California, Connecticut, Nevada, Oregon), allow pre-birth parentage orders for all family structures including same-sex couples and single parents.
- • Restrictive states (Michigan, Louisiana), surrogacy contracts may be unenforceable or carry penalties.
- • International variation. Canada allows altruistic surrogacy only. UK permits surrogacy but contracts are unenforceable. Many European countries ban surrogacy entirely.
Legal counsel specializing in assisted reproduction law is essential. The Gestational Carrier Agreement, parentage strategy, and birth certificate process must be structured according to the specific laws of the state or country where the birth will occur.
Frequently Asked Questions
What is surrogacy?
An arrangement where a carrier gestates and delivers a baby for intended parents. In gestational surrogacy, the carrier has no genetic connection to the child.
What is the difference between gestational and traditional surrogacy?
Gestational: carrier has no genetic link (embryo via IVF). Traditional: carrier's own egg is used (biological mother). Gestational is the standard modern approach.
Who uses surrogacy?
Same-sex male couples, single men, women with medical conditions preventing pregnancy, couples with recurrent IVF failure, and cancer survivors who preserved embryos.
Is surrogacy legal?
Varies by jurisdiction. Legal in most US states, with varying regulations. Some countries ban it entirely. Legal counsel is essential.
How much does surrogacy cost?
US surrogacy typically costs $150,000-$200,000+ including surrogate compensation, agency fees, IVF, legal, and insurance.
Common Misunderstandings
- A single IVF cycle does not guarantee pregnancy.
- Attrition occurs at every biological stage.
- Published success rates may use different measurement units.
- Population statistics do not equal individual outcomes.
