Current Match Time:
Choosing surrogacy often comes after a long, emotional journey. As you move into the medical phase, it’s natural to want clear data, especially about the success rate of embryo transfer to a surrogate.
This information isn’t just about the math; it’s about feeling prepared and confident as you move toward the medical milestones ahead.
If you’d like to better understand how our screening process supports stronger embryo transfer outcomes, or if you’re evaluating your next step after a failed cycle, connect with our team to receive detailed information about our available pre-screened surrogates.
Understanding Embryo Transfers Success Rates in Surrogacy
When researching embryo transfer success rates in surrogacy, you may notice that specific, standardized statistics can be difficult to find because surrogacy outcomes are not always reported separately from broader IVF data.
In surrogacy, embryo transfers take place with carefully screened gestational carriers who have a proven history of healthy, full-term pregnancies. Because of these requirements, success rates are often higher than those reflected in broader IVF averages.
At American Surrogacy, every surrogate must meet rigorous medical qualifications before she is approved for matching and transfer, including a documented history of healthy, full-term pregnancies.
This deliberate approach helps reduce avoidable risk factors at the outset before your journey even begins.
Live Birth Rate vs. Pregnancy Rate: What’s the Difference?
As you review statistics from different clinics or programs, it is important to understand the different success metrics used in the industry. These terms are often confused, but they mark very different stages of success:
The percentage of embryos that successfully attach to the surrogate’s uterine wall. The percentage of transfers that result in a pregnancy confirmed by ultrasound, usually when a fetal heartbeat is detected. The percentage of transfers that result in the delivery of a baby. For most parents, this is the most critical figure to follow.
What Actually Determines Embryo Transfer Success?
While every journey is unique, there isn't a single secret to a successful transfer. Instead, success is built on these essential factors: the laboratory standards of your clinic, the surrogate’s uterine health, and the biological quality of the embryo.
Fertility Clinic & Lab
The expertise of your fertility clinic is just as important as the logistics of your agency. The role of the IVF lab is to provide the optimal environment for your embryos to thrive before they are ever transferred.
- Lab Environment: High-end clinics use advanced air filtration and precise temperature controls to protect delicate embryos.
- Physician Skill: The doctor’s specific technique and the protocol they use for the transfer procedure can directly influence whether an embryo implants successfully.
- Reported Data: It is always a good idea to check a clinic’s specific live birth rates to see their historical performance with gestational carriers.
Surrogate Health
A surrogate’s physical readiness is the foundation of a high success rate of embryo transfer to surrogate. Because surrogates are required to have already carried a child to term, their uterine health is already established before they join a program.
During the screening process, doctors confirm:
The surrogate’s lining must be thick and receptive for the embryo to stick. She must respond well to the medications used to prepare her body for the transfer. A history of healthy, uncomplicated pregnancies suggests a high likelihood of another smooth pregnancy.
Embryo Quality
Even with the best medical care and a healthy surrogate, the health of the embryo is often the most significant predictor of success.
Embryologists grade embryos based on their physical appearance and development speed to identify those with the highest potential.
Many intended parents choose PGT-A (Preimplantation Genetic Testing for Aneuploidies) to screen for chromosomal normality. It is important to clarify that PGT-A testing does not technically increase the chances of a "healthy" pregnancy; rather, it increases the chances of successful implantation by ensuring only the most viable embryos are selected for transfer.
IVF vs. Surrogacy Success Rate
When comparing the IVF vs. surrogacy success rate, the difference often comes down to the "uterine factor."
In standard IVF, patients may be dealing with age-related fertility issues or uterine conditions that make pregnancy difficult or even dangerous.
Surrogacy bypasses these specific medical hurdles.
Because surrogates are pre-screened specifically for their uterine health and have a track record of easy pregnancies, the chances of a live birth are generally higher than for an IVF patient who has experienced repeated failures.
Does the Surrogacy Agency Affect Success Rates?
Because a surrogacy agency does not perform the medical transfer, it does not directly affect the success rate.
While we do not control the medical outcome, American Surrogacy's deliberate surrogate screening is designed to reduce avoidable risks and minimize preventable delays helping keep your journey moving forward and bringing you closer to becoming parents.
How American Surrogacy Sets Families Up for Success
Our surrogates must meet rigorous high health and lifestyle standards set by the American Society for Reproductive Medicine (ASRM), including at least one prior successful pregnancy and a documented medical record free of major complications.
Many of our surrogates have prior surrogacy experience, meaning they have already helped other intended parents live out their dreams of growing their family.
Your path to parenthood is most successful when you have the right team. We can help you find a reputable clinic and match you with a surrogate who has been pre-screened with your success in mind.
