Current Match Time:
Choosing surrogacy is a major decision, often following a long and emotional road toward building your family. As you move into this phase, it’s only natural to look for concrete data to guide your expectations.
You want to understand the success rate of embryo transfer to surrogate carriers and how those numbers apply to your specific situation. This information isn’t just about the math; it’s about feeling prepared and confident as you move toward the medical milestones ahead.
Success in this process isn't determined by an agency’s marketing, it is the result of high-quality embryos, the technical skill of your fertility clinic, and the health of the surrogate you choose. By understanding what really impacts these results, you can approach your transfer with a clear, informed perspective.

Understanding Embryo Transfers Success Rates in Surrogacy
When you begin researching the surrogate embryo transfer success rate, you will likely find that these numbers are often higher than the national averages for standard IVF.
While national IVF data includes patients of all ages and medical backgrounds, surrogacy typically involves a more controlled set of biological factors.
The reason for these higher success rates is largely due to the surrogates themselves.
Unlike a standard IVF cycle where a patient may be struggling with underlying reproductive issues, a gestational surrogate is selected specifically because she has a proven history of healthy, full-term pregnancies. Every surrogate must pass a strict medical screening to ensure her body is physically ready for a successful transfer.
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?
An agency does not perform the medical transfer, but it does manage the variables that lead to success. Our role is to provide a thoroughly screened surrogate who is both medically and emotionally ready for the journey.
While we do not control the medical outcome, American Surrogacy supports you by:
- Strict Vetting: We ensure every surrogate meets high health and lifestyle standards.
- Coordination: We work closely with your clinic to ensure the transfer protocol is followed perfectly.
- Risk Reduction: By screening for a history of healthy pregnancies, we help reduce the likelihood of medical complications.
Controlling what we can control ensures you work with a surrogate who is less likely to experience issues when it comes to the embryo transfer.
How American Surrogacy Can Help Intended Parents Improve Their Chances of Success
Your path to parenthood is most successful when you have the right team. We help you choose a reputable clinic and provide you with a surrogate who has been vetted with your success in mind.
Many of our surrogates have prior surrogacy experience, meaning they have already successfully navigated the medical steps of a transfer before.
If you are ready to see how our screening process can help you, get more information today and let us help you find the right path forward.
