Gestational surrogacy is an arrangement where a woman carries a baby she has no genetic connection to. Doctors create an embryo through IVF using the intended parents' or donors' eggs and sperm, then transfer it to the carrier's uterus, where it develops for nine months.
It accounts for about 95% of surrogacy today, because the absence of a genetic tie keeps the legal and emotional picture clear. This guide covers how it works, what it costs, and the success rates.
Unlike traditional surrogacy, where the carrier's own egg is used, a gestational carrier is not genetically related to the baby at all.
Who gestational surrogacy is for
Gestational surrogacy exists for people who cannot safely carry a pregnancy themselves, and that covers several situations. It helps couples facing infertility or a uterine condition that rules out pregnancy, same-sex couples and single parents who need a carrier and sometimes a donor, and women for whom pregnancy would be medically unsafe. Because success tracks the egg provider's age rather than the carrier's, it can also produce better outcomes for older intended mothers using their own or donor eggs than attempting pregnancy themselves.
The gestational surrogacy process, step by step
The medical process is more involved than traditional surrogacy because it requires IVF, but it follows a predictable sequence. The American College of Obstetricians and Gynecologists publishes guidance on the medical steps.
-
14–6 weeks
Medical and psychological screening
Health evaluations, hormone and infectious-disease testing for the intended parents and carrier; psychological evaluation for the carrier.
-
22–4 weeks
Cycle synchronization
Hormone treatment to prepare the egg provider and medication to prepare the carrier's uterus, timed together.
-
3~1 week
Egg retrieval and fertilization
Eggs are retrieved under light sedation and fertilized in the lab; embryos develop for three to five days.
-
41 day
Embryo transfer
One embryo is placed in the carrier's uterus in a short procedure; a pregnancy test follows about 10 days later.
How to find a gestational surrogate
There are two routes to a carrier, and they trade cost against convenience. An agency keeps a pool of pre-screened surrogates and handles matching, screening, and support for a fee of $30,000 to $60,000. Going independent means finding a surrogate without an agency, through your network or a matching platform, which costs less but puts the coordination on you.
How much gestational surrogacy costs
A full gestational surrogacy journey in the US typically costs $110,000 to $220,000 through an agency, and less if you go independent. The figure depends most on your embryo situation, whether you already have embryos or need IVF or donor eggs. This article keeps the cost summary brief on purpose; the full breakdown, line by line, is in how much does gestational surrogacy cost, and ways to lower it are in how to afford surrogacy.
Success rates
Gestational surrogacy has strong success rates, in part because carriers are screened for healthy pregnancy histories before approval. Live-birth rates are generally around 45% to 55% per embryo transfer, and roughly 70% to 80% of intended parents achieve a pregnancy within three transfers, based on national CDC ART success-rates data and reporting from the Society for Assisted Reproductive Technology. The most important factor is the age of the egg provider, not the carrier: a healthy carrier under 45 has little effect on the odds, while the egg provider's age drives them. If the first transfer does not take, a second is common and not a cause for alarm.
Is gestational surrogacy right for you?
Deciding involves weighing four things together: whether other options remain viable medically, whether you are ready emotionally for someone else to carry your child, whether you can plan for a $110,000-to-$220,000 process that may need more than one transfer, and what your state's law requires. Working with a reproductive attorney and an experienced clinic from the start is the surest way to avoid problems later. For the full journey end to end, see how surrogacy works.
Frequently asked questions
What is gestational surrogacy?
An arrangement where a woman carries a baby created through IVF from the intended parents' or donors' eggs and sperm. The carrier has no genetic connection to the child, and the intended parents are the legal parents.
How does gestational surrogacy work?
Doctors create embryos through IVF, everyone completes medical and legal screening, an embryo is transferred to the carrier, and the pregnancy is monitored to birth. The intended parents become the legal parents, often through a pre-birth order.
How much does gestational surrogacy cost?
Typically $110,000 to $220,000 through an agency in the US, driven mostly by your embryo situation. See how much does gestational surrogacy cost for the full breakdown.
What is the success rate of gestational surrogacy?
Live-birth rates are generally 45% to 55% per transfer, and about 70% to 80% of intended parents achieve pregnancy within three transfers. Success depends mainly on the egg provider's age, not the carrier's.
Can the surrogate keep the baby?
No. The carrier has no genetic tie to the child, and legal contracts plus a parentage order establish the intended parents as the legal parents. She has no parental rights to the baby.
