Embryo Transfer Success Rates

What to Expect in Surrogacy IVF

Learn embryo transfer success rates and how they can affect your surrogacy journey.

When you have been waiting to have the family you dream of, the embryo transfer can feel like a turning point on your journey to parenthood.

Multiple factors influence the embryo transfer success rate, including the quality of the embryo and the age of the individual whose eggs are being used.  The success rates of IVF with a surrogate are 20% higher than those of IVF without a surrogate.

If you have already created embryos or are in the process of doing so, you can be matched with a surrogate quickly. Reach out to us today to get connected with a surrogate and advance to the next step in the surrogacy process.

What is the Success Rate for Embryo Transfer?

The success rate for an IVF embryo transfer to end with a birth ranges from 24-40% on average according to CDC data. Since these numbers are averages, your likelihood of success may be different.

Embryo transfer success rates vary by population group and additional factors can play a role in your success, so as you research embryo transfer rates, it may be useful to consider what factors may affect your pregnancy.  

IVF Using the Intended Mother’s Eggs:

  • Under the age of 35: 49.1%
  • Between the ages of 35-40: 43.5%

IVF Using Donor Eggs or Embryos:

  • Frozen embryo transfer(FET): 46.3%
  • Fresh embryo transfer: 45.8%

When you pursue surrogacy, average transfer success rates can be as high as 75%.

What Affects Embryo Transfer Success Rates?

As you look at IVF embryo transfer success rates, it is a good idea to be aware of your circumstances. The CDC has an IVF success estimator tool that includes many of these variables and may be able to give you a more accurate idea of success rates for people who share similar situations. Below are some of the common factors that can affect success rates.

Health Status

One of the biggest factors affecting IVF success rates is medical conditions and health. Some medical conditions make it difficult or impossible to carry a pregnancy to term.

Consulting a fertility doctor is the best way to determine if you have any medical conditions or factors that may affect your success in IVF. While some medical conditions make pregnancy more difficult or impossible, there are other medical factors, like hormone levels, that can be tracked and treated to increase the likelihood of a successful pregnancy.

Age of the Egg Provider

Age is also a large factor in embryo transfer success rates.  The age of the intended mother or egg donor will impact the quality of their eggs, which in turn can affect the quality of the embryo and the chances of achieving a pregnancy.

While there are successful pregnancies for women in their late 30s, 40s, and occasionally beyond, rates of successful IVF transfer generally begin dropping for women in their mid to late 30s.

Number and Quality of Embryos

IVF cannot be successful if there are no embryos to transfer, and when there are fewer embryos, you have fewer chances to have a successful pregnancy. Having more embryos can also allow your fertility specialists to help you choose an embryo with a higher chance of success.

In some cases couples also choose to use donor sperm, eggs, or embryos that may be of higher quality to increase the likelihood of a successful embryo transfer.

Fertility Clinic and Methods

Many intended parents will compare fertility clinic success rates when considering which clinic to work with. While this is a useful metric, it’s not the bottom line. Individual clinics may have varying success rates, and some may be more equipped to handle your unique situation.

The Society for Assisted Reproductive Technology (SART), an authority on all-things embryos, has said, “It is important to note that patient characteristics vary among programs; therefore, success rates should not be used to compare treatment centers.”

Can Surrogacy Increase Embryo Transfer Success Rates?

Surrogacy can increase embryo transfer success rates drastically.

If you have a medical condition that makes it difficult or impossible to carry a pregnancy, or if your likelihood of successful pregnancy has decreased due to age, finding a surrogate to carry an embryo means you may have a greater likelihood of embryo transfer leading to a successful pregnancy.

No matter what, when you work with American Surrogacy, we protect you to the highest level possible so that you can find success if you experience unsuccessful embryo transfers. You can have unlimited matching if you experience unsuccessful pregnancy attempts, and you will be financially protected. Learn more here.


What is the success rate of the first embryo transfer?

The success rate of the first embryo transfer averages 55%, however, this number depends on the embryo’s health and the age and health of the woman receiving the transfer.

How can I increase my chances of successful embryo transfer?

You can increase your chances of a successful embryo transfer by following the instructions of your physician, who may advise:

  • Taking supportive medications

  • Increasing water and electrolyte consumption

  • Eating healthy and relaxing

  • Avoiding cigarette smoke

  • Taking supplements

  • Avoiding toxic chemicals

  • Reducing alcohol and coffee intake

What are the odds of embryo transfer sticking?

The first embryo transfer has an average success rate of 55%, but not all situations are the same. Having a surrogate who has been approved by a fertility specialist, having high-quality embryos available, and having skilled medical professionals can make a difference in your likelihood of success.
