A surrogate pregnancy is an arrangement in which a woman carries and delivers a baby for another person or couple, known as the intended parents. The surrogate agrees before conception to transfer parental rights after birth, making it possible for people who cannot carry a pregnancy themselves to have children. The entire process, from initial consultations to delivery, typically spans 23 to 27 months and costs between $140,000 and $200,000 in the United States.
Gestational vs. Traditional Surrogacy
The central distinction between the two types of surrogacy is whether the surrogate is genetically related to the baby. In gestational surrogacy, the far more common arrangement today, an embryo is created in a lab using in vitro fertilization (IVF) and then transferred to the surrogate’s uterus. The eggs and sperm may come from the intended parents, from donors, or from a combination of both. The surrogate has no biological connection to the child.
In traditional surrogacy, the surrogate provides her own egg, making her the biological mother of the baby. Fertilization happens through intrauterine insemination using sperm from the intended father or a donor. Because of the genetic link between surrogate and child, traditional surrogacy raises more complex legal and emotional questions, and most agencies and fertility clinics now work exclusively with gestational arrangements.
How the Medical Process Works
If the intended mother is using her own eggs, she takes fertility medication to stimulate her ovaries to produce multiple eggs at once. Those eggs are then retrieved and fertilized with sperm in a lab to create embryos. When donor eggs or donor sperm are used, the same fertilization process applies.
Meanwhile, the surrogate takes separate fertility medication to prepare the lining of her uterus for implantation. Once one or more embryos have developed, a doctor transfers an embryo into the surrogate’s uterus. The IVF cycle itself typically takes about six weeks. If the transfer is successful, a standard pregnancy follows for roughly 40 weeks. CDC data shows that gestational carrier cycles using the intended mother’s eggs have about 17% higher live birth rates per transfer compared to standard IVF cycles, partly because surrogates are carefully screened for their ability to carry a healthy pregnancy.
Who Can Be a Surrogate
Surrogacy agencies and fertility clinics screen candidates against a specific set of medical and lifestyle criteria. Common requirements include being between 21 and 39 years old, having a BMI of 32 or lower, and having already delivered at least one child successfully at full term. A candidate’s medical history must be free of serious pregnancy complications like gestational diabetes, preeclampsia, or preterm delivery.
These standards exist because a surrogate’s track record of uncomplicated pregnancy is one of the strongest predictors of a healthy outcome. The screening process also includes psychological evaluation and background checks, which happen during the early months of the journey before any medical procedures begin.
The Full Timeline
Most surrogacy journeys follow a predictable sequence of phases, though the total length varies based on how quickly a match is found and whether the first embryo transfer succeeds.
- Consultation and sign-on: 1 to 3 months of initial meetings, paperwork, and agency selection.
- Matching with a surrogate: Variable, sometimes weeks, sometimes several months depending on availability and compatibility.
- Medical and legal steps: 3 to 4 months covering medical screenings, legal contracts, and the IVF cycle.
- Pregnancy and delivery: Approximately 9 months.
All told, intended parents should expect the process to take roughly two years from start to finish.
Cost Breakdown
Surrogacy is a significant financial commitment. In the U.S., the total typically falls between $140,000 and $200,000, sometimes more. That breaks down into several major categories.
Surrogate compensation is the largest single expense, ranging from $55,000 to $75,000 or higher. This covers the surrogate’s time, physical commitment, and pregnancy-related costs. Agency fees run $20,000 to $35,000 and pay for surrogate screening, matching, and case management throughout the journey. Medical and IVF costs, including embryo creation, the transfer procedure, medications, and prenatal care through delivery, add another $30,000 to $50,000. Legal fees, insurance, and miscellaneous expenses account for the rest.
Legal Considerations
Surrogacy law in the United States varies dramatically from state to state. There is no federal surrogacy law. California has long been one of the most surrogacy-friendly states, permitting gestational surrogacy under its family code. New York and New Jersey, which had completely prohibited compensated surrogacy since 1992, legalized it in 2021. A few states still restrict or effectively ban surrogacy agreements.
One of the most important legal steps is establishing parentage. In many states, intended parents can obtain a pre-birth parentage order, a court ruling issued before the baby is born that names them as the legal parents. In California, for instance, these orders are available regardless of the parents’ marital status, sexual orientation, or whether they used their own eggs and sperm. Other states only allow post-birth proceedings, which may involve a confirmatory adoption or a court order issued after delivery. In New York, the Child Parent Security Act created a “Surrogate’s Bill of Rights” addressing independent legal counsel for the surrogate, life insurance, and decision-making authority over her own medical care.
Both parties typically need separate attorneys throughout the process. Surrogacy contracts spell out compensation, expectations during pregnancy, parental rights, and what happens in various contingencies. These agreements are the legal backbone of the arrangement, and their enforceability depends entirely on the state where the surrogacy takes place.
Surrogacy Laws Around the World
Globally, surrogacy laws range from fully permissive to outright criminal. The United Kingdom allows surrogacy but does not enforce surrogacy contracts in court, meaning a surrogate could legally choose to keep the child. South Africa permits only altruistic surrogacy (no payment beyond medical expenses), requires a genetic link to at least one intended parent, and mandates approval from a High Court judge.
India was once a major destination for international commercial surrogacy but banned the practice in 2021, allowing only altruistic surrogacy for Indian citizens under strict regulations. Italy took a particularly hard line, passing a 2024 bill that applies universal jurisdiction to surrogacy, meaning Italian citizens could face prosecution for pursuing surrogacy arrangements even in countries where it is legal. The legal landscape is shifting rapidly in many countries, so intended parents considering international surrogacy need current, location-specific legal guidance.
Who Pursues Surrogacy
People turn to surrogacy for a range of reasons. Some intended mothers have medical conditions that make pregnancy dangerous or impossible, such as a history of uterine surgery, recurrent pregnancy loss, or heart conditions. Others may have had a hysterectomy or were born without a uterus. Same-sex male couples use surrogacy as their primary path to biological parenthood. Single men and women also pursue surrogacy when adoption is not the right fit or when they want a genetic connection to their child.
Whatever the reason, the process requires sustained commitment from everyone involved. Surrogates describe the experience as rewarding but physically and emotionally demanding, and intended parents often navigate months of uncertainty before holding their baby for the first time.
