A gestational carrier is a person who carries and delivers a baby for someone else, with no genetic connection to the child. The embryo is created through in vitro fertilization (IVF) using eggs and sperm from the intended parents or donors, then transferred to the carrier’s uterus. The carrier provides the pregnancy, but not the egg, which is the key distinction that separates this arrangement from other forms of surrogacy.
How It Differs From Traditional Surrogacy
The difference comes down to genetics. A traditional surrogate uses her own egg, making her the biological mother of the child. Fertilization typically happens through intrauterine insemination rather than IVF. A gestational carrier, by contrast, has no genetic tie to the baby at all. The embryo is created entirely from other people’s genetic material and placed into her uterus.
This distinction has major legal consequences. Because a traditional surrogate is the genetic mother, she is also considered the legal mother in many jurisdictions. That means the intended parents often need to go through adoption proceedings, sometimes including a stepparent adoption, to be recognized as the child’s legal parents. Gestational surrogacy sidesteps much of this complexity. Traditional surrogacy is actually banned in many states, including New York, largely because of the legal complications it creates. New York legalized compensated gestational carrier arrangements in 2021.
Why People Use a Gestational Carrier
The most straightforward reason is that the intended parent cannot safely carry a pregnancy. This includes people born without a uterus, those who have had a hysterectomy, and those with uterine abnormalities that prevent implantation or full-term pregnancy. People with serious heart or lung conditions, or connective tissue disorders that make pregnancy dangerous, may also turn to a gestational carrier. Recurrent pregnancy loss and repeated IVF failure are other common reasons.
Gestational carriers also make parenthood possible for single men and same-sex male couples who want a biological connection to their child. In these cases, one partner’s sperm is used with a donor egg to create the embryo.
Who Can Be a Gestational Carrier
Not everyone qualifies. The American Society for Reproductive Medicine (ASRM) recommends that carriers be between 21 and 45 years old and have completed at least one uncomplicated, full-term pregnancy before carrying for someone else. That prior pregnancy serves as evidence that the carrier’s body can sustain a healthy pregnancy. ASRM also recommends carriers have no more than five total prior deliveries or three prior cesarean sections.
Beyond those baseline criteria, the screening process is extensive. Candidates go through medical testing, psychological evaluation, and background checks. The psychological assessment looks at the carrier’s motivations, her understanding of the emotional dimensions of carrying a child for someone else, and her support system at home. Intended parents typically undergo their own medical consultations to review embryo quality and treatment options.
The Medical Process
Because the carrier is not providing the egg, the entire process relies on IVF. Eggs are retrieved from the intended mother or a donor and fertilized with sperm in a lab to create embryos. The carrier then takes fertility medications for several weeks to prepare her uterine lining for implantation. Once her body is ready, a doctor transfers the embryo into her uterus.
These medications, which include hormones like estrogen and progesterone, can cause side effects ranging from bloating and mood changes to headaches and injection-site soreness. Once pregnant, the carrier faces the same risks as any pregnancy, plus some that are slightly elevated with IVF. According to the American College of Obstetricians and Gynecologists, pregnancies resulting from assisted reproductive technology carry somewhat higher rates of preeclampsia, placenta previa, cesarean delivery, preterm birth, and low birth weight. The single greatest risk factor is multifetal pregnancy (twins or more), which is why most clinics now transfer only one embryo at a time.
Legal Protections and Parental Rights
A surrogacy agreement is drafted and signed before the embryo transfer takes place. Both sides work with separate attorneys to outline expectations around compensation, medical decisions, communication during pregnancy, and what happens in various scenarios. This contract typically takes one to two months to finalize.
The most important legal step for intended parents is obtaining a parentage order. In many states, this can be done before the baby is born through what’s called a prebirth parentage order. A court declares the intended parents to be the legal parents while the carrier is still pregnant. This has several practical effects: the intended parents’ names go directly on the original birth certificate, they have immediate legal authority over the baby’s medical care at birth, and insurance coverage under their policies is more clearly established. It also allows them to participate in the delivery and hospital experience as the recognized parents from the start.
In states that don’t allow prebirth orders, intended parents may need to establish parentage after birth through a court proceeding. The specific process varies widely by state. Some states are very surrogacy-friendly with clear statutory frameworks, while others have no surrogacy laws on the books, forcing attorneys to work within paternity and adoption statutes that were never designed for these situations.
How Long the Process Takes
From the first steps to delivery, most surrogacy journeys take 15 to 24 months. The timeline breaks down roughly like this:
- Preparation and application: 1 to 6 months of gathering medical records, researching agencies, and deciding to move forward.
- Screening: 1 to 3 months of medical, psychological, and background evaluations.
- Matching: 6 to 10 months. This is often the longest pre-pregnancy phase, as agencies pair carriers and intended parents based on shared values, lifestyle, and expectations.
- Legal contracts: 1 to 2 months.
- Medical preparation and embryo transfer: 1 to 3 months for hormone treatment and the transfer itself.
- Pregnancy and delivery: approximately 9 months, followed by post-birth legal steps to finalize parentage if a prebirth order wasn’t obtained.
What It Costs
Gestational surrogacy is expensive. A complete journey in the United States typically costs between $150,000 and $200,000 or more. The carrier’s compensation is the largest single expense, generally ranging from $68,000 to $90,000 or higher when you include base pay, monthly allowances, and milestone payments. Costs in California, one of the most popular states for surrogacy due to its favorable legal framework, tend to land at the upper end of that range.
The remaining costs cover IVF and medical procedures, legal fees for both parties, agency fees for matching and coordination, the carrier’s pregnancy-related expenses, and insurance. Some intended parents already have embryos frozen from prior IVF cycles, which can reduce the medical portion of the cost. Others need egg or sperm donors, which adds to it. Insurance is a variable that can swing the total significantly depending on whether the carrier’s existing health plan covers surrogacy pregnancies or whether a separate policy needs to be purchased.
